How can make a drop down menu like this in android?

Drop down menu I was wondering how i could make a drop down menu?开发者_StackOverflow And how could you make it go upwards instead of downwards? I have an idea how to get it started but the buttons would have no functionality. Any suggestions appreciated. Thanks!

That looks like a PopupMenu, perhaps. This supports popping up or down based on space, but it is only available on Honeycomb or higher.
