title: How to set a custom seekbar on the default MediaController?
body: <p>I'm looking for a way of setting a custom seekbar on the default MediaController; preferably without having to completely extend the MediaController.</p>
  
  <p>Following the information on this post:
  <a href="https://stackoverflow.com/questions/17637925/android-seek-bar-customization">android seek bar customization,</a>
  I've created a custom seekbar class however I'd like to set that onto the MediaController being used in my VideoPlayerActivity.</p>
  
  <p>Looking at the implementation for the MediaController, it looks like you can retrieve the seekbar Resource using its basic identifier</p>
  
  <pre><code>"mediacontroller_progress", "id", "android"
  </code></pre>
  
  <p>Therefore, is it possible to create a unique resourceId and set the MediaController to retrieve this resource instead? If not, then how would one go about setting the seekbar?</p>
