In my app I'm using a AutoCompleteTextView to select some data. Unfortunately it is possible that the data can change while the AutoCompleteTextView is already on the screen.
Therefore, I want to update the data right before the popup-list is shown.
Is there any lister to execute a function, when the little triagle is clicked?
I already tried:
- setOnFocusChangeListener
- setOnTouchListener
- setOnCreateContextMenuListener
and several more, but nothing really worked.
