title: space between nested scrollview and collapsing toolbar android
body: <p>Helo,</p>
  
  <p>I am working on app for one website. I have an issue with collapsing toolbar and Nested ScrollView.</p>
  
  <p>It looks like this (<a href="http://imgur.com/UpIJa59" rel="nofollow">http://imgur.com/UpIJa59</a>) when you open up the article for the first time. After scrolling down white space between text and image removes.</p>
  
  <p>Here is my layout for this activity:</p>
