One thing I did to get a similar (though not identical) effect is to put
the navbar and the main view in a frame layout.  The navbar pops out from
the left side and shows up on top of the main view.  After making a
selection it hides itself again.

This doesn't do EXACTLY what you are looking for but it provides the same
kind of functionality and isn't that hard to implement.
