title: Custom UI on exoplayer sample
body: <p>** I really need help if you don't know anything don't give me a negative point :| if something bother you comment**</p>
  
  <p>I want to write custom UI for my player in Exoplayer(change button of pause play or add new buttons like player speed next and etc) .</p>
  
  <p>I use Exoplayer sample from github and before add code to my original project, I want to test the custom UI on official sample.</p>
  
  <p>I read pages in Stackoverflow and tuts+ about custom UI but I really confused!</p>
  
  <p>why change some buttons image or change their place must be so difficult :) how i can handle this?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>this is the sample

  <p>I read these two article:</p>
  
  <p><a href="http://www.brightec.co.uk/ideas/custom-android-media-controller" rel="noreferrer">http://www.brightec.co.uk/ideas/custom-android-media-controller</a></p>

  <p>according to this <a href="http://brightec.co.uk/ideas/custom-android-media-controller" rel="noreferrer">link</a> "Instead of writing your own media controller from scratch, you could start with the MediaController class that is included in Android" and I ask this question because i can't do this steps on exoplayer library and tutorial is written for default media player</p>
