This sample demonstrates notifications with custom content views. *
On API level 16 and above a big content view is also defined that is used for the 'expanded' notification. The notification is created by the NotificationCompat.Builder. The expanded content view is set directly on the {@link android.app.Notification} once it has been build. (See {@link android.app.Notification#bigContentView}.)
*
The content views are inflated as {@link android.widget.RemoteViews} directly from their XML layout definitions using {@link android.widget.RemoteViews#RemoteViews(String, int)}.
Create and show a notification with a custom layout. This callback is defined through the 'onClick' attribute of the 'Show Notification' button in the XML layout. * @param v
