It depends somewhat on the minimum SDK that you are targeting. If you are able to write your application with a minimum target of Android 3.0 (API Level 11), then there are at least two classes that you can use to accomplish creating a simple popup anchored to another view (in this case, your button):

ListPopupWindow
PopupMenu

Otherwise, you will need to do a little customization of PopupWindow, which is the class that many early QuickAction implementations are based on.

Design a listview inside it RelativeLayout view in that same layout and make it as invisible. once you click a button at the header you can make it visible. which shows the listview.
