Figure 27-3 shows the effect of setting this property to ifRoom for both menu items: If set to ifRoom, for example, the item will appear in the action bar if there is enough room. The android:showAsAction property, on the other hand, controls the conditions under which the corresponding item appears as an item within the action bar itself. In the above XML, the android:orderInCategory property dictates the order in which the menu items will appear within the menu when it is displayed. The following XML, for example, defines a menu consisting of two menu items relating to color choices: This involves the use of the element, containing an sub-element for each menu item. The items in a menu can be declared within an XML file, which is then inflated and displayed to the user on demand. With the Android 4.0 release and later, on the other hand, the overflow menu button is located in the top right hand corner (Figure 27-2) in the action toolbar represented by the stack of three squares: On a device running Android 2.3.3, for example, the overflow menu is represented by the menu icon located in the center (between the back and search buttons) of the bottom soft key toolbar as illustrated in Figure 27-1: The location of the overflow menu is dependent upon the version of Android that is running on the device. The overflow menu (also referred to as the options menu) is a menu that is accessible to the user from the device display and allows the developer to include other application options beyond those included in the user interface of the application.
