There's a trick involved here. You'll need to:

1. Wrap your layout in a list view
2. Add a fake header with the same height as your action bar large header
3. set your action bar overlay to true
4. Translate the real header when the list moves (i.e. when the fake header is scrolled).

I myself used that link to implement it in my own app and it works great.
