How to make a sidebar menu

I'm looking for a way to develop a menu which could be visible by sliding on the left of the current screen. One example is the mobile version of Firefox, when you slide on the left, you can access to the current tabs navigation, but the main page is still visible. It is called a sidebar I think : EXAMPLE One possible way to do that is to use ViewFlipper, I guess, but maybe is there an easier and more efficient possibility ? And I'm afraid that handling scrolling horizontally and vertically could be a bit difficult... Thanks for any answers, Maxetx.
