/**
* A window feature at the top of the activity that may display the activity title, navigation
* modes, and other interactive items.
* <p>Beginning with Android 3.0 (API level 11), the action bar appears at the top of an
* activity's window when the activity uses the system's {@link
* android.R.style#Theme_Holo Holo} theme (or one of its descendant themes), which is the default.
* You may otherwise add the action bar by calling {@link
* android.view.Window#requestFeature requestFeature(FEATURE_ACTION_BAR)} or by declaring it in a
* custom theme with the {@link android.R.styleable#Theme_windowActionBar windowActionBar} property.
* <p>By default, the action bar shows the application icon on
* the left, followed by the activity title. If your activity has an options menu, you can make
* select items accessible directly from the action bar as "action items". You can also
* modify various characteristics of the action bar or remove it completely.</p>
* <p>From your activity, you can retrieve an instance of {@link ActionBar} by calling {@link
* android.app.Activity#getActionBar getActionBar()}.</p>
* <p>In some cases, the action bar may be overlayed by another bar that enables contextual actions,
* using an {@link android.view.ActionMode}. For example, when the user selects one or more items in
* your activity, you can enable an action mode that offers actions specific to the selected
* items, with a UI that temporarily replaces the action bar. Although the UI may occupy the
* same space, the {@link android.view.ActionMode} APIs are distinct and independent from those for
* {@link ActionBar}.
* <div class="special reference">
* <h3>Developer Guides</h3>
* <p>For information about how to use the action bar, including how to add action items, navigation
* modes and more, read the <a href="{@docRoot}guide/topics/ui/actionbar.html">Action

* - Move down with the d-pad to select an item in the list
* - Move up with the d-pad until the selection disappears
* - Type more text in the AutoCompleteTextView *using the soft keyboard*
* and get new results; you are now in touch mode
* - The selection comes back on the first item in the list, even though
* the list is supposed to be in touch mode
*
* Using the soft keyboard triggers the touch mode change but that change
* is propagated to our window only after the first list layout, therefore
* after the list attempts to resurrect the selection.

* The trick to work around this issue is to pretend the list is in touch
* mode when we know that the selection should not appear, that is when
* we know the user moved the selection away from the list.
