Parallax toolbar initial value
<p>I am not familiar with coordinatorlayout and appbarlayout, i checked <a href="https://github.com/chrisbanes/cheesesquare" rel="nofollow">https://github.com/chrisbanes/cheesesquare</a>. Everything works good, but i have a question, is it possible to set initial height of appbarlayout, like setExpand(true) sets it to full height. Xml:  </p>
