title: Change android seekbar value without clicking direclty on the seekbar thumb
body: <p>I have an android seekbar that appears on the screen when a user touches a button. </p>
  
  <p>How can I start tracking user touch to move the seekbar immediately  after it appears?</p>
  
  <p>To be more clear, essentially I want the user to be able to move the seekbar thumb/progress without clicking directly on it.</p>
