title: Changing from transparent to colored status bar android
body: <p>I'm working on Lollipop &amp; I know how to color the status bar by setting this flag <code>FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS</code> &amp; setting the color by 
  <code>getWindow().setStatusBarColor(color);</code></p>
  
  <p>But I have a image &amp; a transparent <code>ActionBar</code> &amp; I want to show the image behind the action bar &amp; when the users scrolls the <code>ListView</code> below the image the status bar should get fill with color as <code>ActionBar</code></p>
  
  <p>The problem is showing image behind the status bar &amp; later after scrolling  filling status bar with color. I don't know how this effect can be achieved.</p>
  
  <p>Any help would be appreciated</p>
