Handling Menu Selections

Android handles all of an Activity's Menu Item selections using a single event handler, the onOptionsItemSelected method. The Menu Item selected is passed in to this method as the MenuItem parameter.

To react to the menu selection, compare the item.getItemId value to the Menu Item identifiers you used when populating the Menu, and react accordingly, as shown in Listing 4-28.
