Inherited methods

Constants

SHOW_AS_ACTION_ALWAYS

int SHOW_AS_ACTION_ALWAYS

This constant is deprecated.
Use MenuItem.SHOW_AS_ACTION_ALWAYS directly.

Always show this item as a button in an Action Bar. Use sparingly! If too many items are set to always show in the Action Bar it can crowd the Action Bar and degrade the user experience on devices with smaller screens. A good rule of thumb is to have no more than 2 items set to always show at a time.

Constant Value: 2 (0x00000002)

SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW

int SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW

This constant is deprecated.
Use MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW directly.

Constant Value: 8 (0x00000008)

SHOW_AS_ACTION_IF_ROOM

int SHOW_AS_ACTION_IF_ROOM

This constant is deprecated.
Use MenuItem.SHOW_AS_ACTION_IF_ROOM directly.

Show this item as a button in an Action Bar if the system decides there is room for it.

Constant Value: 1 (0x00000001)

SHOW_AS_ACTION_NEVER

int SHOW_AS_ACTION_NEVER

This constant is deprecated.
Use MenuItem.SHOW_AS_ACTION_NEVER directly.

Never show this item as a button in an Action Bar.

Constant Value: 0 (0x00000000)

SHOW_AS_ACTION_WITH_TEXT

int SHOW_AS_ACTION_WITH_TEXT

This constant is deprecated.
Use MenuItem.SHOW_AS_ACTION_WITH_TEXT directly.

When this item is in the action bar, always show it with a text label even if it also has an icon specified.

Constant Value: 4 (0x00000004)

This method is deprecated.
