title: inflate view in user's home/active screen
body: <p>Could someone kindly share how to inflate a <code>View</code> to user's home (or active) screen, like this image :</p>
  
  <p><a href="https://i.stack.imgur.com/A8d0S.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/A8d0S.jpg" alt="enter image description here"></a></p>
  
  <p>The <code>Any.do</code> application can inflate a <code>View</code> on the bottom of my home (or active) screen (the <code>View</code> still inflated even when im playing game) and at the same time displaying a notification.</p>
  
  <p>How to accomplish this? I tried to google but cant get a clue.</p>
  
  <p>Thanks a lot for your help</p>
