How to place fixed button below listview?

Question

Is there any way to have a button directly below a listview, so that as the listview grows, the button moves down BUT the button is never pushed off screen. IE, once the listview has outgrown the screen, the button is still always visible, and the listview is scrollable.

I have managed to make the button ALWAYS at the bottom of the screen, but i want it to sit up directly below the listview while the listview is smaller than the screen.

I have tried using various arrangements of relative and linear layouts and using the weight property, and things that seem like they should work simply don't, so it might be worth checking any answers before posting.

CLARIFICATION: To phrase it in a different way: I want a button to sit below a listview, moving down as it grows, but i dont want the button to be pushed offscreen

Answer 1

This previous post does exactly what you want to do. What it does basically is that it keeps the button at the bottom of the list at all times. But when the list grows out of the screen area, its height gets limited by the weight parameter.
This way, the list's bottom edge is just above the button's LinearLayout and you get the same behavior that you were looking for.
