UTILIZING THE ACTION BAR
Besides fragments, another newer feature introduced in Android 3 and 4 is the Action Bar. In place
of the traditional title bar located at the top of the device’s screen, the Action Bar displays the
application icon together with the activity title. Optionally, on the right side of the Action Bar are
action items. Figure 3-28 shows the built-in Email application displaying the application icon, the
activity title, and some action items in the Action Bar. The next section discusses action items in
more detail.
Adding Action Items to the Action Bar
Besides displaying the application icon and the activity title on the left of the Action Bar, you can
also display additional items on the Action Bar. These additional items are called action items.
Action items are shortcuts to some of the commonly performed operations in your application. For
example, you might be building an RSS reader application, in which case some of the action items
might be “Refresh feed,” “Delete feed” and “Add new feed.”
