        DoneBarActivity
        Done Bar
        In this presentation, a done bar replaces the action bar entirely, providing
            two direct actions to persist or dismiss changes. This is suitable for cases where no
            additional view details or actions are needed in the action bar.
    
    
        DoneButtonActivity
        Done Button
        In this presentation, a done button replaces the action bar\'s "Up" affordance
            and app icon, while the cancel action is made available in the action overflow. This is
            well-suited to scenarios where additional view details or
            actions may be needed in the action bar.

This sample shows how to create a custom view in the ActionBar to show a done button, using
2 alternative layouts. This is well suited for simple data entry activities, where the only
options for the user are to cancel or confirm the data changes.
        
        
API 11 introduced the [ActionBar][1] as a navigational UI element. In most cases, a custom view isn't required
or even recommended, as using a menu xml file is all that is needed to add action icons to it. However, it is
possible to use a custom view and it is useful in some cases.
This sample contains two activities with custom views in their action bar, each with a "done" button. These are
designed to be used with simple data entry screen where the only options for the user are to cancel or confirm
the changes.
1. Create a layout for the [ActionBar][2].
2. In the activity, before setting the content view, inflate the view using the LayoutInflater.
3. Use `getActionBar()` to get the ActionBar, and set the display options with `ActionBar.DISPLAY_SHOW_CUSTOM`.
4. Set the custom view by calling `setCustomView(customActionBarView, new ActionBar.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT))` on the ActionBar.
5. You can now set the content view of the Activity.
