Which of the following is NOT true about the MenuItem interface?
A . The MenuItem instance will be returned by the Menu class add(…) method.
B . MenuItem can decide the Intent issued when clicking menu components.
C . MenuItem can display either an icon or text.
D . MenuItem can set a checkbox.

Answer: C

Explanation:

Both an icon and text can be displayed.

The <item> element supports several attributes you can use to define an item’s appearance and behavior. The items in the above menu include the following attributes:

android:id

A resource ID that’s unique to the item, which allows the application to recognize the item when the user selects it.

android:icon

A reference to a drawable to use as the item’s icon.

android:title

A reference to a string to use as the item’s title.

Incorrect:

B: Adding Menu Items Based on an Intent

Sometimes you’ll want a menu item to launch an activity using an Intent (whether it’s an activity in your application or another application). When you know the intent you want to use and have a specific menu item that should initiate the intent, you can execute the intent with startActivity() during the appropriate on-item-selected callback method (such as the onOptionsItemSelected() callback).

However, if you are not certain that the user’s device contains an application that handles the intent, then adding a menu item that invokes it can result in a non-functioning menu item, because the intent might not resolve to an activity. To solve this, Android lets you dynamically add menu items to your menu when Android finds activities on the device that handle your intent.
