Android AutoCompletionTextView hide popup?

Question

Steps to reproduce:

1. Make a AutoCompleteTextView
2. Click on AutoCompleteTextView -> OnScreenKeyBoard is displayed.
3. Press a few characters, AutoCompleteTextView has new characters and Popup appears.
4. Press done. OnScreenKeyBoard hides (using InputMethodManager.hideSoftInputFromWindow)
5. Auto complete popup is still there.

If I touch the screen it goes away, but its annoying.

How do I hide that popup programaticaly(is that the word?) Can I simulate a Touch event on textview? I don't see something like AutoCompleteTextView.hidePopup()

Thanks, Abhi
