Adding a button to the widget is just a matter of putting it in your layout. In your code, you can attach a PendingIntent to be invoked when that button is clicked. You can see that in one of the samples out of my _Android Programming Tutorials_ book: http://github.com/commonsguy/cw-andtutorials/tree/master/36-AdvAppWidget/ For your case, though, the challenge is in the "next most contacted contact" part. Widgets have no real state, so either you would need to teach the Button's PendingIntent what the "next most contacted contact" is, or you would have to keep a file or database table or something that knows what the widget is currently showing, so you can determine what is "next" to be shown. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html
