Solution

An Action Bar and a dashboard might be better suited to what your trying to do, or just use an options menu. Have a look at 'Google I/O 2010 - Android UI design patterns' on youtube. That will help you ask clearer questions. Motodev Studio will help getting started with what you learn in the video (but I personally don't like the code generated).

If after watching the video above you still want the home button like your screenshot you could probably use a relative layout with a layout include or fragment aligned to the bottom, with the include or fragment containing a image button.

Actually both methods above require similar code, but action bars are cool.
