body: <p>I want to customize the SeekBar as shown below in the image.<img src="https://i.stack.imgur.com/oSNWh.png" alt="Make a seekbar like this one"></p>
  
  <p>I'm a beginner in programming and I looked for tutorials, but every where the progress starts in the leftmost corner. Can someone please guide me how can I customize the SeekBar.</p>
  
  <p>So In onProgresschanged.</p>
  
  <pre><code> @Override
   public void onProgressChanged(SeekBar seekBar,int progress, boolean fromUser) {            
  brightness = progress;
      putGestureImageOnScreen(doBrightness(imageBitmap, brightness));
   }
  </code></pre>
  
  <p>Thanks.</p>
