title: android Seekbar show progress value along the seekbar
body: <p>I have a <code>listview</code> with <code>seekbar</code>, each <code>seekbar</code> represents 100% of a value of product. By moving the <code>seekbar</code> the % value can be changed, I want to show the change in value along the seekbar while the user is dragging the <code>seekbar</code>. I do <em>not</em> wish to add another text box where the value is updated. </p>
  
  <p>I am more looking at options to show a small view on top of the seekbar pointer, which appears <code>onStartTracking</code> and disappears <code>onStopTracking</code> event. </p>
  
  <p>Is there a way to achieve this?</p>
