A DialogFragment is a fragment that displays a dialog window, floating on top of its activity's window.

This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog.
