So I've got a screen layout with a title and the top, a bunch of buttons at the bottom, and a listview in the middle.

I want the listview to take up as much height as it can.

What's my move here? I can set absolute pixels, but I really, really don't want to.

The answer is using the layout_weight attribute, which will override the height/weight specified (depending on whether the enclosing linearlayout is horizontally or vertically aligned). The trick is to make sure nothing at a higher level is at wrap_content, because in that case there isn't any extra room for the weighted element to claim.
