However, it is 14 possible to use a custom view and it is useful in some cases. 15 16 This sample contains two activities with custom views in their action bar, each with a "done" button. These are 17 designed to be used with simple data entry screen where the only options for the user are to cancel or confirm 18 the changes. 19 20 1. Create a layout for the [ActionBar][2]. 21 2.
