      <title>Standalone fragment</title>

      <description>&lt;p&gt;To use the fragment together with an existing toolbar/action bar, a few things should be overridden.&lt;/p&gt;

&lt;p&gt;Here&amp;rsquo;s a minimal example where the toolbar is intercepted from being set as the main toolbar. The menu creation is also intercepted and populates the toolbar directly.&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;class&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;StandaloneFilePickerFragment&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;extends&lt;/span&gt; FilePickerFragment &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;

    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;protected&lt;/span&gt; Toolbar mToolbar&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;protected&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;void&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;setupToolbar&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;Toolbar toolbar&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// Prevent it from being set as main toolbar by NOT calling super.setupToolbar().&lt;/span&gt;
        mToolbar &lt;span style=&#34;color: #666666&#34;&gt;=&lt;/span&gt; toolbar&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;
    &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;

    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;void&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;onCreateOptionsMenu&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;Menu menu&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; MenuInflater inflater&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// Populate the toolbar with the menu items instead of the action bar.&lt;/span&gt;
        mToolbar&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;inflateMenu&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;R&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;menu&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;picker_actions&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;

        &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// Set a menu listener on the toolbar with calls the regular onOptionsItemSelected method.&lt;/span&gt;
        mToolbar&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;setOnMenuItemClickListener&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;new&lt;/span&gt; Toolbar&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;OnMenuItemClickListener&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;()&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;boolean&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;onMenuItemClick&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;MenuItem item&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
                &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; onOptionsItemSelected&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;item&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
            &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;});&lt;/span&gt;

      <title>Override selection behavior</title>
      <link>http://spacecowboy.github.io/NoNonsense-FilePicker/example/override_selection_behavior/</link>
      <pubDate>Sat, 16 Jul 2016 17:35:01 +0200</pubDate>
      
      <guid>http://spacecowboy.github.io/NoNonsense-FilePicker/example/override_selection_behavior/</guid>
      <description>

&lt;p&gt;New in &lt;a href=&#34;https://github.com/spacecowboy/NoNonsense-FilePicker/releases/tag/v2.4.0&#34;&gt;2.4.0&lt;/a&gt; are overridable methods to handle UI-interactions. The following methods are now available for augmentation:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;onClickOK, handles ok button.&lt;/li&gt;
&lt;li&gt;onClickCancel, handles cancel button.&lt;/li&gt;
&lt;li&gt;onClickHeader, handles clicks on &amp;ldquo;..&amp;rdquo;.&lt;/li&gt;
&lt;li&gt;onClickDir, handles clicks on non-selectable items (usually directories).&lt;/li&gt;
&lt;li&gt;onLongClickDir, handles long clicks on non-selectable items.&lt;/li&gt;
&lt;li&gt;onClickCheckable, handles clicks on selectable items.&lt;/li&gt;
&lt;li&gt;onLongClickCheckable, handles long clicks on selectable items.&lt;/li&gt;
&lt;li&gt;onClickCheckBox, handles clicks on the checkbox of selectable items.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Please see the existing implementations before you override any of them.&lt;/p&gt;

&lt;h2 id=&#34;simple-example-make-clicks-instantly-select-items&#34;&gt;Simple example, make clicks instantly select items&lt;/h2&gt;

&lt;p&gt;As asked in &lt;a href=&#34;https://github.com/spacecowboy/NoNonsense-FilePicker/issues/48&#34;&gt;#48&lt;/a&gt;, what if the picker is configured for selecting a single file and you want a click on that to instantly return the result. The default implementation will mark the item as selected, and then the user is required to press the OK button. This small change will make the operation a single click action, returning instantly once the user selects something.&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;class&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;SingleFilePickerFragment&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;extends&lt;/span&gt; FilePickerFragment &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;void&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;onClickCheckable&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;View v&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; CheckableViewHolder vh&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;if&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(!&lt;/span&gt;allowMultiple&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// Clear is necessary, in case user clicked some checkbox directly&lt;/span&gt;
            mCheckedItems&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;clear&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;();&lt;/span&gt;
            mCheckedItems&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;add&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;vh&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;file&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
            onClickOk&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;null&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;else&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;super&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;onClickCheckable&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;v&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; vh&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
    &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;p&gt;Now the astute reader might wonder, if my filepicker is only going to be used for selecting single files, why not just do:&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;void&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;onClickCheckable&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;View v&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; CheckableViewHolder vh&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;super&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;onClickCheckable&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;v&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; vh&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
    onClickOk&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;null&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
&lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;p&gt;The reason is that the default implementation will animate the checkbox being selected on press. If you are closing the picker directly once the user selects something, you are basically animating something which isn&amp;rsquo;t going to be seen and thus you are wasting (not that much) resources. Better to not animate at all in that case.&lt;/p&gt;

      <title>Override the back button</title>
      <link>http://spacecowboy.github.io/NoNonsense-FilePicker/example/override_back_button/</link>
      <pubDate>Sat, 16 Jul 2016 17:33:43 +0200</pubDate>

      <description>

&lt;p&gt;In case you want the back button to navigate the hierarchy instead of
instantly exiting the activity, this is one approach you might take.&lt;/p&gt;

&lt;h2 id=&#34;create-an-activity-which-overrides-the-back-button-and-loads-a-custom-fragment&#34;&gt;Create an activity which overrides the back button and loads a custom fragment&lt;/h2&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;code&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;package&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;com.nononsenseapps.filepicker.examples.backbutton&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;import&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;android.os.Environment&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;import&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;com.nononsenseapps.filepicker.AbstractFilePickerFragment&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;import&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;java.io.File&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;class&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;BackHandlingFilePickerActivity&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;extends&lt;/span&gt; FilePickerActivity &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;

    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;/**&lt;/span&gt;

&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     */&lt;/span&gt;
    BackHandlingFilePickerFragment currentFragment&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;/**&lt;/span&gt;

&lt;p&gt;By default, the SD-card picker will display all files in alphabetical order. But let&amp;rsquo;s say that your app can only handle a specific type of file, like &lt;code&gt;.txt&lt;/code&gt;-files. Here&amp;rsquo;s a minimal example which will only display such files.&lt;/p&gt;

&lt;p&gt;First, a convenience method to get the extension of files:&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// File extension to filter on, including the initial dot.&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;private&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;static&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;final&lt;/span&gt; String EXTENSION &lt;span style=&#34;color: #666666&#34;&gt;=&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;&amp;quot;.txt&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;

    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;/**&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     *&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * @param file&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * @return The file extension. If file has no extension, it returns null.&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     */&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;private&lt;/span&gt; String &lt;span style=&#34;color: #06287e&#34;&gt;getExtension&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@NonNull&lt;/span&gt; File file&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        String path &lt;span style=&#34;color: #666666&#34;&gt;=&lt;/span&gt; file&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;getPath&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;();&lt;/span&gt;
        &lt;span style=&#34;color: #902000&#34;&gt;int&lt;/span&gt; i &lt;span style=&#34;color: #666666&#34;&gt;=&lt;/span&gt; path&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;lastIndexOf&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;&amp;quot;.&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;if&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;i &lt;span style=&#34;color: #666666&#34;&gt;&amp;lt;&lt;/span&gt; &lt;span style=&#34;color: #40a070&#34;&gt;0&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;null&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;else&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; path&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;substring&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;i&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
    &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;p&gt;The decision to display files or not is done with the &lt;code&gt;isItemVisible&lt;/code&gt; method. Just add a check for the file-extension:&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;protected&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;boolean&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;isItemVisible&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;final&lt;/span&gt; File file&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// simplified behavior   (see below full code)&lt;/span&gt;
        &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;// return isDir(file) || (mode == MODE_FILE || mode == MODE_FILE_AND_DIR);&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;if&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(!&lt;/span&gt;isDir&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;file&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;&amp;amp;&amp;amp;&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;mode &lt;span style=&#34;color: #666666&#34;&gt;==&lt;/span&gt; MODE_FILE &lt;span style=&#34;color: #666666&#34;&gt;||&lt;/span&gt; mode &lt;span style=&#34;color: #666666&#34;&gt;==&lt;/span&gt; MODE_FILE_AND_DIR&lt;span style=&#34;color: #666666&#34;&gt;))&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            String ext &lt;span style=&#34;color: #666666&#34;&gt;=&lt;/span&gt; getExtension&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;file&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; ext &lt;span style=&#34;color: #666666&#34;&gt;!=&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;null&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;&amp;amp;&amp;amp;&lt;/span&gt; EXTENSION&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;equalsIgnoreCase&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;ext&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; isDir&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;file&lt;span style=&#34;color: #666666&#34;&gt;);&lt;/span&gt;

    &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;

&lt;p&gt;Say you want to browse some files which have really long names. By default, filenames will be cut if they exceed one line in width like &lt;code&gt;ThisIsAReallyLongFi...&lt;/code&gt;. What if we really wanted it show like in this image?&lt;/p&gt;

&lt;p&gt;&lt;img src=&#34;http://spacecowboy.github.io/NoNonsense-FilePicker/screenshots/itemlayout_longfilename.png&#34; alt=&#34;Example of a long filename&#34; /&gt;&lt;/p&gt;

&lt;p&gt;The behavior of the text is defined in the listitem layouts:

&lt;a href=&#34;https://github.com/spacecowboy/NoNonsense-FilePicker/blob/master/library/src/main/res/layout/nnf_filepicker_listitem_dir.xml&#34;&gt;nnf_filepicker_listitem_dir&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;There are two kinds of layouts, one with a checkbox to allow selection, and one without a checkbox. The second one is also used for the special header item &lt;code&gt;..&lt;/code&gt; though you could of course have a special layout for that if you wanted.&lt;/p&gt;

&lt;h3 id=&#34;layouts&#34;&gt;Layouts&lt;/h3&gt;

&lt;p&gt;Let&amp;rsquo;s create some new layouts which will support longer filenames as follows:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;longer_listitem_checkable.xml&lt;/strong&gt;&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020&#34;&gt;&amp;lt;?xml version=&amp;quot;1.0&amp;quot; encoding=&amp;quot;utf-8&amp;quot;?&amp;gt;&lt;/span&gt;
&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;LinearLayout&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;xmlns:android=&amp;quot;http://schemas.android.com/apk/res/android&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;xmlns:tools=&amp;quot;http://schemas.android.com/tools&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;match_parent&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;wrap_content&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:background=&amp;quot;?android:selectableItemBackground&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:minHeight=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:orientation=&amp;quot;horizontal&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;gt;&lt;/span&gt;


    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;&amp;lt;!--suppress AndroidDomInspection --&amp;gt;&lt;/span&gt;
    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;ImageView&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:id=&amp;quot;@+id/item_icon&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:adjustViewBounds=&amp;quot;true&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:scaleType=&amp;quot;fitCenter&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:src=&amp;quot;@drawable/nnf_ic_file_folder&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:tint=&amp;quot;?attr/colorAccent&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:visibility=&amp;quot;visible&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;tools:ignore=&amp;quot;ContentDescription&amp;quot;&lt;/span&gt; &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;

    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;TextView&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:id=&amp;quot;@android:id/text1&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;style=&amp;quot;?android:textAppearanceLarge&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;0dp&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;wrap_content&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:minHeight=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_weight=&amp;quot;1&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:ellipsize=&amp;quot;end&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:gravity=&amp;quot;center_vertical&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:maxLines=&amp;quot;4&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:padding=&amp;quot;8dp&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;

    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;CheckBox&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:id=&amp;quot;@+id/checkbox&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;wrap_content&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;match_parent&amp;quot;&lt;/span&gt;

&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;/LinearLayout&amp;gt;&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;p&gt;&lt;strong&gt;longer_listitem_dir.xml&lt;/strong&gt;&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020&#34;&gt;&amp;lt;?xml version=&amp;quot;1.0&amp;quot; encoding=&amp;quot;utf-8&amp;quot;?&amp;gt;&lt;/span&gt;
&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;LinearLayout&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;xmlns:android=&amp;quot;http://schemas.android.com/apk/res/android&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;xmlns:tools=&amp;quot;http://schemas.android.com/tools&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;match_parent&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;wrap_content&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:background=&amp;quot;?android:selectableItemBackground&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:minHeight=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #4070a0&#34;&gt;android:orientation=&amp;quot;horizontal&amp;quot;&lt;/span&gt;
    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;gt;&lt;/span&gt;

    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;&amp;lt;!--suppress AndroidDomInspection --&amp;gt;&lt;/span&gt;
    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;ImageView&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:id=&amp;quot;@+id/item_icon&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:adjustViewBounds=&amp;quot;true&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:scaleType=&amp;quot;center&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:src=&amp;quot;@drawable/nnf_ic_file_folder&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:tint=&amp;quot;?attr/colorAccent&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:visibility=&amp;quot;visible&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;tools:ignore=&amp;quot;ContentDescription&amp;quot;&lt;/span&gt; &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;

    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;TextView&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:id=&amp;quot;@android:id/text1&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;style=&amp;quot;?android:textAppearanceLarge&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_width=&amp;quot;0dp&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_height=&amp;quot;wrap_content&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:minHeight=&amp;quot;?android:listPreferredItemHeight&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:layout_weight=&amp;quot;1&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:ellipsize=&amp;quot;end&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:gravity=&amp;quot;center_vertical&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:maxLines=&amp;quot;4&amp;quot;&lt;/span&gt;
        &lt;span style=&#34;color: #4070a0&#34;&gt;android:padding=&amp;quot;8dp&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;
&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;/LinearLayout&amp;gt;&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;p&gt;Note that I defined the TextViews to have a maximum of 4 lines (actual number is up to you), and a minimum height of &lt;code&gt;android:listPreferredItemHeight&lt;/code&gt; (this I recommend, otherwise it looks wonky and off-center). And just be clear, the &lt;em&gt;ids&lt;/em&gt; of these fields must be &lt;code&gt;@+id/item_icon&lt;/code&gt;, &lt;code&gt;@android:id/text1&lt;/code&gt;, and &lt;code&gt;@+id/checkbox&lt;/code&gt;, or the code WILL crash on you.&lt;/p&gt;

&lt;h3 id=&#34;code&#34;&gt;Code&lt;/h3&gt;

&lt;p&gt;To use the new layouts, you need to override the &lt;code&gt;onCreateViewHolder&lt;/code&gt; method in
&lt;a href=&#34;https://github.com/spacecowboy/NoNonsense-FilePicker/blob/master/library/src/main/java/com/nononsenseapps/filepicker/AbstractFilePickerFragment.java&#34;&gt;AbstractFilePickerFragment&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Since this example will be browsing the SD-card, I will extend from the built-in FilePickerFragment.&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;class&lt;/span&gt; &lt;span style=&#34;color: #0e84b5; font-weight: bold&#34;&gt;CustomLayoutFilePickerFragment&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;extends&lt;/span&gt; FilePickerFragment &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;/**&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * @param parent Containing view&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * @param viewType which the ViewHolder will contain. Will be one of:&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * [VIEWTYPE_HEADER, VIEWTYPE_CHECKABLE, VIEWTYPE_DIR]. It is OK, and even expected, to use the same&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * layout for VIEWTYPE_HEADER and VIEWTYPE_DIR.&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     * @return a view holder for a file or directory (the difference is presence of checkbox).&lt;/span&gt;
&lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;     */&lt;/span&gt;
    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; RecyclerView&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;ViewHolder&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;onCreateViewHolder&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;ViewGroup parent&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;int&lt;/span&gt; viewType&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        View v&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;switch&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;viewType&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;case&lt;/span&gt; LogicHandler&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;VIEWTYPE_HEADER&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;:&lt;/span&gt;

&lt;p&gt;And as always, to use your custom fragment you need a custom activity which loads it for you:&lt;/p&gt;

    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;CustomLayoutPickerActivity&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;()&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;super&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;();&lt;/span&gt;
    &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;

    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;protected&lt;/span&gt; AbstractFilePickerFragment&lt;span style=&#34;color: #666666&#34;&gt;&amp;lt;&lt;/span&gt;File&lt;span style=&#34;color: #666666&#34;&gt;&amp;gt;&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;getFragment&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;

      <title>Change the sort order</title>

      <description>

&lt;p&gt;By default, the SD-card picker will display all files in alphabetical order. But what if you want a different sort-order?&lt;/p&gt;

&lt;p&gt;You can override the sorting by overriding the &lt;code&gt;compareFiles&lt;/code&gt;-method:&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;    &lt;span style=&#34;color: #555555; font-weight: bold&#34;&gt;@Override&lt;/span&gt;
    &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;protected&lt;/span&gt; &lt;span style=&#34;color: #902000&#34;&gt;int&lt;/span&gt; &lt;span style=&#34;color: #06287e&#34;&gt;compareFiles&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;File lhs&lt;span style=&#34;color: #666666&#34;&gt;,&lt;/span&gt; File rhs&lt;span style=&#34;color: #666666&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;if&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;lhs&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;isDirectory&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;()&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;&amp;amp;&amp;amp;&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;!&lt;/span&gt;rhs&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;isDirectory&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;())&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
            &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;-&lt;/span&gt;&lt;span style=&#34;color: #40a070&#34;&gt;1&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;
        &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;else&lt;/span&gt; &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;if&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;(&lt;/span&gt;rhs&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;isDirectory&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;()&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;&amp;amp;&amp;amp;&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;!&lt;/span&gt;lhs&lt;span style=&#34;color: #666666&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color: #4070a0&#34;&gt;isDirectory&lt;/span&gt;&lt;span style=&#34;color: #666666&#34;&gt;())&lt;/span&gt; &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;

&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Extendable for sources other than SD-card (Dropbox, FTP, Drive, etc)&lt;/li&gt;
&lt;li&gt;Can select multiple items&lt;/li&gt;
&lt;li&gt;Select directories or files, or both&lt;/li&gt;
&lt;li&gt;Create new directories in the picker&lt;/li&gt;
&lt;li&gt;Material theme with AppCompat&lt;/li&gt;
&lt;/ul&gt;

&lt;h2 id=&#34;yet-another-file-picker-library&#34;&gt;Yet another file picker library?&lt;/h2&gt;

&lt;p&gt;I needed a file picker that had two primary properties:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Easy to extend: I needed a file picker that would work for normal
files on the SD-card, and also for using the Dropbox API.&lt;/li&gt;
&lt;li&gt;Able to create a directory in the picker.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;This project has both of those qualities. As a bonus, it also scales
nicely to work on any phone or tablet. The core is placed in abstract
classes, so it is fairly easy to extend the picker to create
your own.&lt;/p&gt;

&lt;p&gt;The library includes an implementation that allows the user to pick
files from the SD-card. But the picker could easily be extended to get
its file listings from another source, such as Dropbox, FTP, SSH and
so on. The sample app includes implementations which browses your
Dropbox and a Linux mirror FTP-server.&lt;/p&gt;

&lt;p&gt;By inheriting from an Activity, the picker is able to be rendered as
full screen on small screens and as a dialog on large screens. It does
this through the theme system, so it is very important for the
activity to use a correctly configured theme.&lt;/p&gt;

&lt;h2 id=&#34;how-to-include-in-your-project-with-gradle&#34;&gt;How to include in your project (with Gradle)&lt;/h2&gt;

&lt;p&gt;Just add the dependency to your &lt;em&gt;build.gradle&lt;/em&gt;:&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;repositories &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
    jcenter&lt;span style=&#34;color: #666666&#34;&gt;()&lt;/span&gt;
&lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;

dependencies &lt;span style=&#34;color: #666666&#34;&gt;{&lt;/span&gt;
    compile &lt;span style=&#34;color: #4070a0&#34;&gt;&amp;#39;com.nononsenseapps:filepicker:3.0.0&amp;#39;&lt;/span&gt;
&lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;h2 id=&#34;how-to-use-the-included-sd-card-picker&#34;&gt;How to use the included SD-card picker:&lt;/h2&gt;

&lt;h3 id=&#34;include-permission-in-your-manifest&#34;&gt;Include permission in your manifest&lt;/h3&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;uses-permission&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;android:name=&amp;quot;android.permission.WRITE_EXTERNAL_STORAGE&amp;quot;&lt;/span&gt; &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;h3 id=&#34;include-the-file-picker-activity&#34;&gt;Include the file picker activity&lt;/h3&gt;

&lt;p&gt;The intent filter is optional depending on your use case. Note that
the theme set in the manifest is important.&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;activity&lt;/span&gt;
       &lt;span style=&#34;color: #4070a0&#34;&gt;android:name=&amp;quot;com.nononsenseapps.filepicker.FilePickerActivity&amp;quot;&lt;/span&gt;
       &lt;span style=&#34;color: #4070a0&#34;&gt;android:label=&amp;quot;@string/app_name&amp;quot;&lt;/span&gt;
       &lt;span style=&#34;color: #4070a0&#34;&gt;android:theme=&amp;quot;@style/FilePickerTheme&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;gt;&lt;/span&gt;
       &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;intent-filter&amp;gt;&lt;/span&gt;
          &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;action&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;android:name=&amp;quot;android.intent.action.GET_CONTENT&amp;quot;&lt;/span&gt; &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;
          &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;category&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;android:name=&amp;quot;android.intent.category.DEFAULT&amp;quot;&lt;/span&gt; &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;/&amp;gt;&lt;/span&gt;
       &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;/intent-filter&amp;gt;&lt;/span&gt;
    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;/activity&amp;gt;&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;h3 id=&#34;configure-the-theme&#34;&gt;Configure the theme&lt;/h3&gt;

&lt;p&gt;You must &lt;strong&gt;set the theme&lt;/strong&gt; on the activity, but you can configure it to
match your existing application theme. You can also name it whatever
you like..&lt;/p&gt;
&lt;div class=&#34;highlight&#34; style=&#34;background: #f0f0f0&#34;&gt;&lt;pre style=&#34;line-height: 125%&#34;&gt;&lt;span&gt;&lt;/span&gt;    &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;&amp;lt;!-- You can also inherit from NNF_BaseTheme.Light --&amp;gt;&lt;/span&gt;
    &lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;lt;style&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;name=&amp;quot;FilePickerTheme&amp;quot;&lt;/span&gt; &lt;span style=&#34;color: #4070a0&#34;&gt;parent=&amp;quot;NNF_BaseTheme&amp;quot;&lt;/span&gt;&lt;span style=&#34;color: #062873; font-weight: bold&#34;&gt;&amp;gt;&lt;/span&gt;
        &lt;span style=&#34;color: #60a0b0; font-style: italic&#34;&gt;&amp;lt;!-- Set these to match your theme --&amp;gt;&lt;/span&gt;

&lt;/pre&gt;&lt;/div&gt;

&lt;h2 id=&#34;customizing-the-picker&#34;&gt;Customizing the picker&lt;/h2&gt;

&lt;p&gt;Extend &lt;code&gt;AbstractFilePickerActivity&lt;/code&gt; and implement &lt;code&gt;getFragment&lt;/code&gt;. It
should return an instance of &lt;code&gt;AbstractFilePickerFragment&lt;/code&gt;. This
basically means that the activity is just the same boilerplate with as
single line changed (see the sample app&amp;rsquo;s Dropbox example for an
activity which actually has to do some extra work):&lt;/p&gt;

        &lt;span style=&#34;color: #007020; font-weight: bold&#34;&gt;return&lt;/span&gt; fragment&lt;span style=&#34;color: #666666&#34;&gt;;&lt;/span&gt;
    &lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;span style=&#34;color: #666666&#34;&gt;}&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;

&lt;h3 id=&#34;extend-abstractfilepickerfragment&#34;&gt;Extend AbstractFilePickerFragment&lt;/h3&gt;

&lt;p&gt;Which requires you to implement&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;onNewFolder&lt;/li&gt;
&lt;li&gt;isDir&lt;/li&gt;
&lt;li&gt;getParent&lt;/li&gt;
&lt;li&gt;getPath&lt;/li&gt;
&lt;li&gt;getFullPath&lt;/li&gt;
&lt;li&gt;getName&lt;/li&gt;
&lt;li&gt;getRoot&lt;/li&gt;
&lt;li&gt;toUri&lt;/li&gt;
&lt;li&gt;getLoader&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;If you only want to make a custom SD-card picker, you can instead extend &lt;code&gt;FilePickerFragment&lt;/code&gt;, and only override the relevant method you want to change.&lt;/p&gt;

&lt;p&gt;See the sample app and the examples for some concrete code.&lt;/p&gt;

--------------------------------

2.1. Grants

Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:

(a) under intellectual property rights (other than patent or trademark)
    Licensable by such Contributor to use, reproduce, make available,
    modify, display, perform, distribute, and otherwise exploit its
    Contributions, either on an unmodified basis, with Modifications, or
    as part of a Larger Work; and

(b) under Patent Claims of such Contributor to make, use, sell, offer
    for sale, have made, import, and otherwise transfer either its
    Contributions or its Contributor Version.

2.2. Effective Date

The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.

2.3. Limitations on Grant Scope

The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:

(a) for any code that a Contributor has removed from Covered Software;
    or

(b) for infringements caused by: (i) Your and any other third party&amp;#39;s
    modifications of Covered Software, or (ii) the combination of its
    Contributions with other software (except as part of its Contributor
    Version); or

(c) under Patent Claims infringed by Covered Software in the absence of
    its Contributions.

This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).

2.4. Subsequent Licenses

No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).

2.5. Representation

Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.

2.6. Fair Use

This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.

2.7. Conditions

Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.

3. Responsibilities
-------------------

3.1. Distribution of Source Form

All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients&amp;#39; rights in the Source Code
Form.

3.2. Distribution of Executable Form

If You distribute Covered Software in Executable Form then:

(a) such Covered Software must also be made available in Source Code
    Form, as described in Section 3.1, and You must inform recipients of
    the Executable Form how they can obtain a copy of such Source Code
    Form by reasonable means in a timely manner, at a charge no more
    than the cost of distribution to the recipient; and

(b) You may distribute such Executable Form under the terms of this
    License, or sublicense it under different terms, provided that the
    license for the Executable Form does not attempt to limit or alter
    the recipients&amp;#39; rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).

3.4. Notices

You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.

4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------

If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.

5. Termination
--------------

5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.

*  statutory, including, without limitation, warranties that the       *
*  Covered Software is free of defects, merchantable, fit for a        *
*  particular purpose or non-infringing. The entire risk as to the     *
*  quality and performance of the Covered Software is with You.        *
*  Should any Covered Software prove defective in any respect, You     *
*  (not any Contributor) assume the cost of any necessary servicing,   *
*  repair, or correction. This disclaimer of warranty constitutes an   *
*  essential part of this License. No use of any Covered Software is   *
*  authorized under this License except under this disclaimer.         *

*  jurisdictions do not allow the exclusion or limitation of           *
*  incidental or consequential damages, so this exclusion and          *

*                                                                      *
************************************************************************

8. Litigation
-------------

Any litigation relating to this License may be brought only in the
courts of a jurisdiction where the defendant maintains its principal
place of business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions.
Nothing in this Section shall prevent a party&amp;#39;s ability to bring
cross-claims or counter-claims.

9. Miscellaneous
----------------

This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not be used to construe this License against a Contributor.

10. Versions of the License
---------------------------

10.1. New Versions

Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.

10.2. Effect of New Versions

You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.

10.3. Modified Versions

If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).

10.4. Distributing Source Code Form that is Incompatible With Secondary
