title: Android NestedScrollView's child views ignoring first click
body: <p>I am using Coordinator layout along with NestedScrollView in my fragment for the Collapsing Toolbar animation. I am adding views dynamically to my Nested Scrollview container. I have implemented onClickListener on the views inside NestedScrollView, but the first click on any view is always ignored. When I tap for a second time or more than it works. The code for my XML is as follows:</p>

  <p>It seems like NestedScrollView is intercepting the touch event and not passing to a child for the first time. 
  How do I fix this issue? </p>
