<p>This is a demo application highlighting how to use some of the new APIs in
|
|
Honeycomb, including:</p>
|
|
|
|
<ul>
|
|
<li><a href="../../../guide/topics/fundamentals/fragments.html">Fragments</a></li>
|
|
<li>The <a href="../../../guide/topics/ui/actionbar.html">action bar</a>
|
|
and contextual action bar</li>
|
|
<li>Drag and drop</li>
|
|
<li>The new <a href="../../../reference/android/animation/package-summary.html"><code>android.animation</code></a>
|
|
framework</li>
|
|
<li>Custom notifications</li>
|
|
<li>For information on how to implement <a href="../../../reference/android/widget/StackView.html"><code>StackView</code></a>
|
|
and other adapter-based app widgets, see <a href="../StackWidget/index.html">StackView App Widget</a></li>
|
|
</ul>
|
|
|
|
<p>The image gallery shows how all these pieces can work together in one application.</p>
|
|
|
|
<p class="note"><strong>Update:</strong> This app has been updated for Android 4.0 to support
|
|
handsets by reusing fragments in separate activities when on smaller screens.</p>
|
|
|
|
<p>The application includes the following key classes:<p>
|
|
<ul>
|
|
<li><a href="src/com/example/android/hcgallery/ContentFragment.html">ContentFragment</a>
|
|
A fragment responsible for containing the "content" of the application.
|
|
Displays images, receives drag/drop events from other fragments, and can
|
|
invoke the contextual action bar using
|
|
<a href="../../../reference/android/view/ActionMode.html">action modes</a>.</li>
|
|
<li><a href="src/com/example/android/hcgallery/TitlesFragment.html">TitlesFragment</a>
|
|
Shows a ListView of photos to display in the ContentFragment. Photos can
|
|
be chosen either by tapping on the listview, or dragging them from the
|
|
list to the content area. The list of photos displayed depends on the
|
|
category selected in the ActionBar.</li>
|
|
<li><a href="src/com/example/android/hcgallery/MainActivity.html">MainActivity</a>
|
|
This is the main entry point of the application. MainActivity is
|
|
responsible for initialization of the ActionBar, TitlesFragment, and
|
|
ContentFragment. MainActivity is also responsible for keeping track of
|
|
the currently selected theme and currently selected photo when the
|
|
activity is recreated, such as when the screen is rotated or an intent to
|
|
a separate activity is fired (such as the included Camera sample).
|
|
MainActivity also contains code demonstrating how to animate
|
|
showing/hiding fragments (in this case, the TitlesFragment) and the
|
|
ActionBar, demonstrating how to smoothly transition between states
|
|
in your application.</li></ul>
