Remarks

Interface for managing the items in a menu.

By default, every Activity supports an options menu of actions or options. You can add items to this menu and handle clicks on your additions. The easiest way of adding menu items is inflating an XML file into the Menu via MenuInflater. The easiest way of attaching code to clicks is via Activity#onOptionsItemSelected(MenuItem) and Activity#onContextItemSelected(MenuItem).

Different menu types support different features: <ol> <li><b>Context menus</b>: Do not support item shortcuts and item icons. <li><b>Options menus</b>: The <b>icon menus</b> do not support item check marks and only show the item's MenuItem#setTitleCondensed(CharSequence) condensed title. The <b>expanded menus</b> (only available if six or more menu items are visible, reached via the 'More' item in the icon menu) do not show item icons, and item check marks are discouraged. <li><b>Sub menus</b>: Do not support item icons, or nested sub menus. </ol>

Methods

Add(ICharSequence)

Add a new item to the menu.

Add(Int32, Int32, Int32, ICharSequence)

Add a new item to the menu.

Add(Int32, Int32, Int32, Int32)

Variation on #add(int, int, int, CharSequence) that takes a string resource identifier instead of the string itself.

Add(Int32)

Add a new item to the menu.

AddIntentOptions(Int32, Int32, Int32, ComponentName, Intent[], Intent, MenuAppendFlags, IMenuItem[])

Add a group of menu items corresponding to actions that can be performed for a particular Intent.

AddSubMenu(ICharSequence)

Add a new sub-menu to the menu.

AddSubMenu(Int32, Int32, Int32, ICharSequence)

Add a new sub-menu to the menu.

AddSubMenu(Int32, Int32, Int32, Int32)

Variation on #addSubMenu(int, int, int, CharSequence) that takes a string resource identifier for the title instead of the string itself.

AddSubMenu(Int32)

Add a new sub-menu to the menu.

Clear()

Remove all existing items from the menu, leaving it empty as if it had just been created.
