Methods Summary
public MenuItem	add(java.lang.CharSequence title) Add a new item to the menu. This item displays the given title for its label. param title The text to display for the item. return The newly added menu item.
public MenuItem	add(int titleRes) Add a new item to the menu. This item displays the given title for its label. param titleRes Resource identifier of title string. return The newly added menu item.
public MenuItem	add(int groupId, int itemId, int order, java.lang.CharSequence title) Add a new item to the menu. This item displays the given title for its label. param 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 {@link #NONE} if an item should not be in a group. param itemId Unique item ID. Use {@link #NONE} if you do not need a unique ID. param order The order for the item. Use {@link #NONE} if you do not care about the order. See {@link MenuItem#getOrder()}. param title The text to display for the item. return The newly added menu item.
public MenuItem	add(int groupId, int itemId, int order, int titleRes) Variation on {@link #add(int, int, int, CharSequence)} that takes a string resource identifier instead of the string itself. param 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 {@link #NONE} if an item should not be in a group. param itemId Unique item ID. Use {@link #NONE} if you do not need a unique ID. param order The order for the item. Use {@link #NONE} if you do not care about the order. See {@link MenuItem#getOrder()}. param titleRes Resource identifier of title string. return The newly added menu item.
public int	addIntentOptions(int groupId, int itemId, int order, android.content.ComponentName caller, android.content.Intent[] specifics, android.content.Intent intent, int flags, MenuItem[] outSpecificItems) 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 {@link Intent#CATEGORY_ALTERNATIVE} or {@link Intent#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 {@link android.content.pm.PackageManager#queryIntentActivityOptions} 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 {@link MenuItem#setIntent} 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. param 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 {@link #NONE} if the items should not be in a group. param itemId Unique item ID. Use {@link #NONE} if you do not need a unique ID. param order The order for the items. Use {@link #NONE} if you do not care about the order. See {@link MenuItem#getOrder()}. param caller The current activity component name as defined by queryIntentActivityOptions(). param specifics Specific items to place first as defined by queryIntentActivityOptions(). param intent Intent describing the kinds of items to populate in the list as defined by queryIntentActivityOptions(). param flags Additional options controlling how the items are added. param 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. return The number of menu items that were added. see #FLAG_APPEND_TO_GROUP see MenuItem#setIntent see android.content.pm.PackageManager#queryIntentActivityOptions
public SubMenu	addSubMenu(java.lang.CharSequence title) Add a new sub-menu to the menu. This item displays the given title for its label. To modify other attributes on the submenu's menu item, use {@link SubMenu#getItem()}. param title The text to display for the item. return The newly added sub-menu
public SubMenu	addSubMenu(int titleRes) Add a new sub-menu to the menu. This item displays the given title for its label. To modify other attributes on the submenu's menu item, use {@link SubMenu#getItem()}. param titleRes Resource identifier of title string. return The newly added sub-menu
public SubMenu	addSubMenu(int groupId, int itemId, int order, java.lang.CharSequence title) Add a new sub-menu to the menu. This item displays the given title for its label. To modify other attributes on the submenu's menu item, use {@link SubMenu#getItem()}. Note that you can only have one level of sub-menus, i.e. you cannnot add a subMenu to a subMenu: An {@link UnsupportedOperationException} will be thrown if you try. param 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 {@link #NONE} if an item should not be in a group. param itemId Unique item ID. Use {@link #NONE} if you do not need a unique ID. param order The order for the item. Use {@link #NONE} if you do not care about the order. See {@link MenuItem#getOrder()}. param title The text to display for the item. return The newly added sub-menu
public SubMenu	addSubMenu(int groupId, int itemId, int order, int titleRes) Variation on {@link #addSubMenu(int, int, int, CharSequence)} that takes a string resource identifier for the title instead of the string itself. param 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 {@link #NONE} if an item should not be in a group. param itemId Unique item ID. Use {@link #NONE} if you do not need a unique ID. param order The order for the item. Use {@link #NONE} if you do not care about the order. See {@link MenuItem#getOrder()}. param titleRes Resource identifier of title string. return The newly added sub-menu

public void	removeGroup(int groupId) Remove all items in the given group. param groupId The group to be removed. If there are no items in this group, nothing happens.
public void	removeItem(int id) Remove the item with the given identifier. param id The item to be removed. If there is no item with this identifier, nothing happens.
public void	setGroupCheckable(int group, boolean checkable, boolean exclusive) Control whether a particular group of items can show a check mark. This is similar to calling {@link MenuItem#setCheckable} on all of the menu items with the given group identifier, but in addition you can control whether this group contains a mutually-exclusive set items. This should be called after the items of the group have been added to the menu. param group The group of items to operate on. param checkable Set to true to allow a check mark, false to disallow. The default is false. param exclusive If set to true, only one item in this group can be checked at a time; checking an item will automatically uncheck all others in the group. If set to false, each item can be checked independently of the others. see MenuItem#setCheckable see MenuItem#setChecked
