I think you need to spend some more time with some tutorials, such as:
http://developer.android.com/guide/tutorials/notepad/index.html
1. You have not connected a View.OnClickListener to your Button
2. Your guide class is unused, and probably should not be there, with your
onClick() implementation being moved to the View.OnClickListener you have
not set up
The Notepad tutorial, linked to above, will demonstrate how to use a Button.
