Class Overview

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 onOptionsItemSelected(MenuItem) and onContextItemSelected(MenuItem).

Different menu types support different features:

  1. Context menus: Do not support item shortcuts and item icons.
  2. Options menus: The icon menus do not support item check marks and only show the item's condensed title. The expanded menus (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.
  3. Sub menus: Do not support item icons, or nested sub menus.

Public Methods

public abstract MenuItem add (CharSequence title)

Added in API level 1

Add a new item to the menu. This item displays the given title for its label.

Parameters
title The text to display for the item.
Returns
  • The newly added menu item.

public abstract MenuItem add (int groupId, int itemId, int order, int titleRes)

Added in API level 1

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

Parameters
groupId The group identifier that this item should be part of. This can also be used to define groups of items for batch state changes. Normally use NONE if an item should not be in a group.
itemId Unique item ID. Use NONE if you do not need a unique ID.
order The order for the item. Use NONE if you do not care about the order. See getOrder().
titleRes Resource identifier of title string.
Returns
  • The newly added menu item.

public abstract MenuItem add (int titleRes)

Added in API level 1

Add a new item to the menu. This item displays the given title for its label.

Parameters
titleRes Resource identifier of title string.
Returns
  • The newly added menu item.

public abstract MenuItem add (int groupId, int itemId, int order, CharSequence title)

Added in API level 1

Add a new item to the menu. This item displays the given title for its label.

Parameters
groupId The group identifier that this item should be part of. This can be used to define groups of items for batch state changes. Normally use NONE if an item should not be in a group.
itemId Unique item ID. Use NONE if you do not need a unique ID.
order The order for the item. Use NONE if you do not care about the order. See getOrder().
title The text to display for the item.

public abstract int addIntentOptions (int groupId, int itemId, int order, ComponentName caller, Intent[] specifics, Intent intent, int flags, MenuItem[] outSpecificItems)

Added in API level 1

Add a group of menu items corresponding to actions that can be performed for a particular Intent. The Intent is most often configured with a null action, the data that the current activity is working with, and includes either the CATEGORY_ALTERNATIVE or CATEGORY_SELECTED_ALTERNATIVE to find activities that have said they would like to be included as optional action. You can, however, use any Intent you want.

See queryIntentActivityOptions(ComponentName, Intent[], Intent, int) for more * details on the caller, specifics, and intent arguments. The list returned by that function is used to populate the resulting menu items.

All of the menu items of possible options for the intent will be added with the given group and id. You can use the group to control ordering of the items in relation to other items in the menu. Normally this function will automatically remove any existing items in the menu in the same group and place a divider above and below the added items; this behavior can be modified with the flags parameter. For each of the generated items setIntent(Intent) is called to associate the appropriate Intent with the item; this means the activity will automatically be started for you without having to do anything else.

Parameters
groupId The group identifier that the items should be part of. This can also be used to define groups of items for batch state changes. Normally use NONE if the items should not be in a group.
itemId Unique item ID. Use NONE if you do not need a unique ID.
order The order for the items. Use NONE if you do not care about the order. See getOrder().
caller The current activity component name as defined by queryIntentActivityOptions().
specifics Specific items to place first as defined by queryIntentActivityOptions().
intent Intent describing the kinds of items to populate in the list as defined by queryIntentActivityOptions().
flags Additional options controlling how the items are added.
outSpecificItems Optional array in which to place the menu items that were generated for each of the specifics that were requested. Entries may be null if no activity was found for that specific action.
Returns
  • The number of menu items that were added.
