setIcon

public MenuItem setIcon(android.graphics.drawable.Drawable icon)

Parameters:

icon - The new icon (as a Drawable) to be displayed.

Returns:

This Item so additional setters can be called.

setIcon

public MenuItem setIcon(int iconRes)

Description copied from interface: MenuItem

Change the icon associated with this item. This icon will not always be shown, so the title should be sufficient in describing this item. See Menu for the menu types that support icons.

setIntent

public MenuItem setIntent(android.content.Intent intent)

Description copied from interface: MenuItem

Change the Intent associated with this item. By default there is no Intent associated with a menu item. If you set one, and nothing else handles the item, then the default behavior will be to call Context.startActivity(android.content.Intent) with the given Intent.

Note that setIntent() can not be used with the versions of Menu.add(java.lang.CharSequence) that take a Runnable, because Runnable.run() does not return a value so there is no way to tell if it handled the item. In this case it is assumed that the Runnable always handles the item, and the intent will never be started.

Specified by:

setIntent in interface MenuItem

Parameters:

intent - The Intent to associated with the item. This Intent object is not copied, so be careful not to modify it later.

Returns:

This Item so additional setters can be called.
