AdMob AdView apears on top of ListView in Android

Question

I am trying to get an AdView to appear at the bottom of my layout, its sort of working but for some reason my AdView is covering the last few rows of my ListView, instead of apearing right after it. I have tried a bunch of things including setting the ListView with height 0px. and weight 1, all with no luck. Any clues?
