title: MapView and Expandablelistview scrolling
body: <p>I have troubles with scrollview and nestedscrollview. 
  I try to make a view where on the top there is a map and below the google map there is a expandable listview. And I want to scroll through the whole view so it's like that the google map is a part of the expandablelistview.</p>
  
  <p>My xml looks like that</p>

  <p>I tried to use a scrollview and in this code snippet a nestedscrollview but both didn't work. 
  When i say that nestedScrollingEnabled=true at the expandablelistview only the listview scrolls but not the map. Do you have any idea how to solve this?
  By the way, I have a similar view but there I use a recyclerview instead of the expandablelistview and this works fine. So, I think the main problem is the expandablelistview but I can't replace this because my listview has to expand. Or is there any possibility to bypass the expandablelistview?</p>
  
  <p>Maybe you need also the layout files from my item in the expandablelistview
