A FrameLayout allows you to have a view overlapping another view. I'm not sure it makes sense to have them with only one child view, as you have in your example. Try having a FrameLayout at the highest level, with your "static" view as the first child element, and the floating menu as the second child.
The developer documents have a good overview the layout types, it might help you get started.
RelativeLayout
is what you want.
FrameLayout
must only have one child, and is therefore, usually, only used for a placeholder where other layouts come later (such as the main frame of the activity).
AbsoluteLayout
is deprecated, and should not be used.
RelativeLayout
allows the views to overlap, and allows doing, pretty much, anything you want.
