1. Make your Activity translucent by adding these two lines to your theme:

<stylename="AppTheme" ...>
<!-- ... -->
<itemname="android:windowBackground">@android:color/transparent</item>
<itemname="android:windowIsTranslucent">true</item>
<!-- also translucent system ui -- suggested but not required -->
<itemname="android:windowTranslucentStatus">true</item>
<itemname="android:windowTranslucentNavigation">true</item>
</style>

2. Wraps ooo.oxo.library.widget.PullBackLayout around your ImageView or ViewPager:

<ooo.oxo.library.widget.PullBackLayout
android:id="@+id/puller"android:layout_width="match_parent"android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="@+id/pager"android:layout_width="match_parent"android:layout_height="match_parent" />
</ooo.oxo.library.widget.PullBackLayout>

3. Set a callback:

publicclassViewerActivityextendsAppCompatActivityimplementsPullBackLayout.Callback {
@OverrideprotectedvoidonCreate(BundlesavedInstanceState) {
super.onCreate(savedInstanceState);
/* ... */puller.setCallback(this);
}
@OverridepublicvoidonPullStart() {
// fade out Action Bar ...// show Status Bar ...
}
@OverridepublicvoidonPull(floatprogress) {
// set the opacity of the window's background
}
@OverridepublicvoidonPullCancel() {
// fade in Action Bar
}
@OverridepublicvoidonPullComplete() {
supportFinishAfterTransition();

}
