I have a dialog window that covers 1/3 of the entire screen height and is displayed on top of my activity. The dialog holds two AutoCompleteTextView fields.
The problem
As seen here: Scrolling drop-down-menu over the keyboard in autocompletetextview
You can use the property android:dropDownHeight of the AutoCompleteTextView to force it to be of a certain height. This is not really solving the problem, but is the best I could find.
Note: This problem only happens when using AutoCompleteTextView inside a Dialog. When it is used on the layout of an activity or a fragment it just works fine.
This issue is present all the way from Gingerbread to Jelly Bean.
