I also do not understand what you're trying to do, but you can try to navigate the template ( http://developer.android.com/design/patterns/navigation.html#up-vs-back ).

You need to declare in his manifesto that action A is the parent of the action B, and then use NavUtils.navigateUpFromSameTask(this); in your OnClickListener button. (NavUtils stored in the package support.v4).
