Android SeekBar setOnSeekBarChangeListener

Question

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   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   In short  I am searching for a possibility to get a progress listener that is called for every little progress change

Seekbar called onProgressChanged method when we initialize first time  We can skip by using below code We need to check boolean it return false when initialize automatically volumeManager setOnSeekBarChangeListener new SeekBar OnSeekBarChangeListener                  Override             public void onProgressChanged SeekBar seekBar  int i  boolean b                    if b                       mAudioManager setStreamVolume AudioManager STREAM MUSIC  i  0                                                 Override             public void onStartTrackingTouch SeekBar seekBar                                 Override             public void onStopTrackingTouch SeekBar seekBar

onProgressChanged is called every time you move the cursor    Override public void onProgressChanged SeekBar seekBar  int progress  boolean fromUser        textView setText String valueOf new Integer progress                 so textView should show the progress and alter always if the seekbar is being moved

All answers are correct  but you need to convert a long big fat number into a timer first       public String toTimer long milliseconds       String finalTimerString           String secondsString         Convert total duration into time     int hours    int   milliseconds    1000 60 60        int minutes    int  milliseconds    1000 60 60      1000 60       int seconds    int    milliseconds    1000 60 60      1000 60    1000          Add hours if there     if hours  gt  0           finalTimerString   hours                     Prepending 0 to seconds if it is one digit     if seconds  lt  10           secondsString    0    seconds       else          secondsString        seconds       finalTimerString   finalTimerString   minutes         secondsString         return timer string     return finalTimerString      And this is how you use it    Override public void onProgressChanged SeekBar seekBar  int progress  boolean fromUser    textView setText String format   s   toTimer progress

onProgressChanged   should be called on every progress changed  not just on first and last touch  that why you have onStartTrackingTouch   and onStopTrackingTouch   methods    Make sure that your SeekBar have more than 1 value  that is to say your MAX  3   In your onCreate    yourSeekBar  SeekBar  findViewById R id yourSeekBar    yourSeekBar setOnSeekBarChangeListener new yourListener       Your listener   private class yourListener implements SeekBar OnSeekBarChangeListener            public void onProgressChanged SeekBar seekBar  int progress                  boolean fromUser                                   Log the progress             Log d  DEBUG    Progress is    progress                                 set textView s text             yourTextView setText    progress                      public void onStartTrackingTouch SeekBar seekBar              public void onStopTrackingTouch SeekBar seekBar              Please share some code and the Log results for furter help
