Ribbon Menu Android

Ok, I got it. It's simple.

getWindow().getDecorView();

This line gives you the main View of your activity. The main view contains all the things that are displayed in the activity. Then you can animate it. The answer was simple.

EDIT:

This is not the way to proceed. Like Cyril Mottier said it's a hack and I found a lot of problems. I redid everything and now I'm implementing my own ActionBar.
