title: Android NestedScrollView has wrong size after app:layout_behavior
body: <p>Since Google has published the design support library for android, there are many nice things that can be done without implementing custom code. While i've tested the custom views in this lib, i have found a worse thing, and i didn't know if this is a bug or not.</p>
  
  <p>I have found the cheesesquare project on github. In the <em>activity_detail.xml(layout file)</em> there are 3 CardViews inside the NestedScrollView. If you delete 2 of them, you can see that the NestedScrollView doesn't have the full size of the parent(match_parent). The NestedScrollView is bound to the bottom of the parent view. <a href="http://i.stack.imgur.com/BXl7w.png">http://i.stack.imgur.com/BXl7w.png</a></p>
  
  <p>The NestedScrollView get's his full size when i remove the <code>app:layout_behavior="@string/appbar_scrolling_view_behavior"</code>. </p>
  
  <p>But when i remove the layout behavior, the toolbar is not collapsing.</p>
  
  <p>Is there any fix for this? Example layout file can be found here: <a href="https://github.com/Smove/cheesesquare/blob/stackoverflow/app/src/main/res/layout/activity_detail.xml">https://github.com/Smove/cheesesquare/blob/stackoverflow/app/src/main/res/layout/activity_detail.xml</a></p>
  
  <p>You can build the cheesesquare apk from my github branch <code>stackoverflow</code></p>
