title: Nested ScrollView with multiple ListViews does not scroll
body: <p>I just want my nested scrollview to scroll, I do not want the lists to scroll. For some reason the scrollview does not scroll. I looked into multiple posts related to nested scroll views, scroll views, with listview, none of the solution helped. It is strange that the scrollview is not working, I am not certain if I am missing something. 
  Also, my listviews are of dynamic heights.</p>
  
  <p>Here is my code: </p>
  
  <pre><code>&lt;android.support.v4.widget.NestedScrollView
