I think it's part of the action bar in android 3.0 and up. http://developer.android.com/guide/topics/ui/actionbar.html

To use it in earlier version you have to create it your self or I think you can use open source action bar. like http://actionbarsherlock.com/

You could just build a list inside a relative layout and make it invisible until you press the button.

Looks like a normal Spinner to me.

Here is an example: http://developer.android.com/resources/tutorials/views/hello-spinner.html
