title: Android SeekBar setOnSeekBarChangeListener
body: <p>I'm wondering about the behavior of the android SeekBars OnSeekBarChangeListener. In particular, is the onProgressChanged-method notified only for the first and the last touch on the seekbar?</p>
  
  <p>I'm trying to refresh a TextView that should show the current progress of the SeekBar. But the TextView is just updated on first touch and last touch. Debugging this confirms my assumption that this method is called just twice :( What I would like to have is that the TextView shows every progress change in the SeekBar.</p>
  
  <p>In short: I am searching for a possibility to get a progress listener that is called for every little progress change.</p>
