What is a SeekBar?

A progress bar that can be dragged (most commonly used in the player)

 seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
   @Override
   public void onStopTrackingTouch(SeekBar seekBar) {
     System.out.println("onStopTrackingTouch");
   }
   @Override
   public void onStartTrackingTouch(SeekBar seekBar) {
     System.out.println("onStartTrackingTouch");
   }
   @Override
   public void onProgressChanged(SeekBar seekBar, int progress,
       boolean fromUser) {
     System.out.println("progress : " + progress);
   }
 });

   @Override
   public void onRatingChanged(RatingBar ratingBar, float rating,
       boolean fromUser) {
     System.out.println(rating);
   }
