Android :: Can I Use Wrap TabHost Containing MapView Displays AdMob View Below It

I'm very new to Android (like 2 days), but I'm experienced with other layout toolkits. I'm trying to put an AdView below a TabHost, and it seems that I can either get the TabWidget or the AdView to display correctly, but never both.

First, here's an ASCII art version of what I'm trying to accomplish:

--------------------------------------------
| Tab 1 | Tab 2 |
--------------------------------------------
| MapView when tab 1 is selected |
| |
| |
| |
| |
| |
| |
--------------------------------------------
| AdView that stays no matter what tab |
--------------------------------------------

As you can see, I'm trying to get the AdView outside the TabWidget or FrameLayout. I want it to be below the whole tabhost contents.

Here's the layout I've got before adding the AdView...

Unfortunately, in that one, my MapView in the first tab puts the Zoom controls on top of the AdView. Is there some simple layout I'm missing? Cuz I can get the TabWidget to wrap_content for height, or the AdView to wrap_content for height, but only when they go above the "@android:id/tabcontent."

Anything below the tab content gets eaten by the MapView.
