title: Play Newsstand kind of animating reveal effect toolbar color change ,how?
body: <p>Many of you might've tried the new google play newsstand with the all new material design.It looks pretty amazing.</p>
  
  <p>I would love to know how to achieve the looks it has.
  So let me narrow it down for you.</p>
  
  <ol>
  <li>How do I do the parallax effect , scroll down toolbar disappears and the reappears as a smaller one on a slight scroll to the top and then fades into the bigger toolbar.</li>
  </ol>
  
  <p>2.the toolbar reveal animation when we swipe tabs.</p>
  
  <p>It has two components , one - the circle in the middle of the toolbar fades in , two - it continues as another circle reveals itself along with an animated color change .</p>
  
  <p>I have made no progress in my research so I come here..nonetheless I'll keep searching for those in my situation.</p>
  
  <p>Thank you</p>
