Android GridView causing view to be on top of ActionBar

I have a view in which I'm creating a popupwindow. In this popupwindow I have a text box (edittext). When clicking to edit the text, the keyboard opens and the whole view goes up, but the top of the view goes under the action bar view. So far so good.

I now have added an empty gridview without any furthur configuration to the popupwindow, and now the same scenario happends but the whole top part of the view goes on top of the action bar view.

Any idea?
