Android Popup picker?

Question

I am looking for the right UI widget to use for this requirement:

When the user clicks a button, a modal list appears, the user clicks and item and then the focus is returned to the active Activity.

Answer 1

You could do that with a dialog. And you can customize the dialog with custom views as per your needs.

Answer 2

You should check AlertDialog and setSingleChoiceItems on this link

Answer 3

This sounds like a ContextMenu.
