QUESTION: 32

What two methods you have to override when implementing Android option menus?

onCreateOptionsMenu, onCreateContextMenu
onCreateContextMenu, onContextItemSelected
onCreateOptionsMenu, onOptionsItemSelected
onCreateOptionsMenu, onContextItemSelected

Answer(s): C

Explanation:

To specify the options menu for an activity, override onCreateOptionsMenu().
When the user selects an item from the options menu (including action items in the app bar), the system calls your activity's onOptionsItemSelected() method. This method passes the MenuItem selected. You can identify the item by calling getItemId(), which returns the unique ID for the menu item (defined by the android:id attribute in the menu resource or with an integer given to the add() method). You can match this ID against known menu items to perform the appropriate action.
For example:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Etc.

To specify the options menu for an activity, override onCreateOptionsMenu() (fragments provide their own onCreateOptionsMenu() callback). In this method, you can inflate your menu resource (defined in XML) into the Menu provided in the callback. For example:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);
return true;
