My activity has configChanges="orientation" so that the activity is
reused across orientation changes. If I have a ListPopupWindow
displaying before the orientation change, it does not get positioned
correctly after the orientation change. Is this a known issue?
Furthermore, I cannot figure how to force it to be positioned
correctly. I tried creating a new instance in #onConfigurationChanged,
but even that does not work. Any idea how I can get it to be
positioned correctly?
Thanks,
Shri
