Your image shows a Dialog containing a ListView. There are several examples of using Dialogs in Android's Demo API.
I have just completed a tutorial adding transparent panels to a MapView that you can view here:

Although I think my tutorial will help you some and recommend that you check it out, DON'T use my transparent panel approach to create the exact image you've posted above. For that, embed a ListView into a Dialog. I'm working on a 2nd tutorial that shows how to best use transparent panels in MapViews. E.g. you need a transparent panel as in my tutorial if you want to overlay navigation buttons onto a MapView as you see at the bottom of Android's Google Map when viewing directions.
Best of luck,
