Android DoneBar Sample

This sample shows how to create a custom view in the ActionBar to show a done button, using 2 alternative layouts. This is well suited for simple data entry activities, where the only options for the user are to cancel or confirm the data changes.

Introduction

API 11 introduced the ActionBar as a navigational UI element. In most cases, a custom view isn't required or even recommended, as using a menu xml file is all that is needed to add action icons to it. However, it is possible to use a custom view and it is useful in some cases.

This sample contains two activities with custom views in their action bar, each with a "done" button. These are designed to be used with simple data entry screen where the only options for the user are to cancel or confirm the changes.

1. Create a layout for the ActionBar.
2. In the activity, before setting the content view, inflate the view using the LayoutInflater.
3. Use getActionBar() to get the ActionBar, and set the display options with ActionBar.DISPLAY_SHOW_CUSTOM.
4. Set the custom view by calling setCustomView(customActionBarView, new ActionBar.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT)) on the ActionBar.
5. You can now set the content view of the Activity.
