How to detect whether a seekbar progress change is decreasing or increasing?

Question

The progress change event can be notified by onProgressChanged in interface OnSeekBarChangeListener().

But how to know whether a change decrease the progress or increase it? Or is there an interface or method like: onSeekBarProgressDecreased(....) or onSeekBarProgressIncreased(...)

Answer 1

There is no interface available for progress decrease or increase events. You have to keep track of it. You can use something like this.

int prevProgress;
mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){
     @Override
      public oid onProgressChanged (SeekBar seekBar, int progress, boolean fromUser){
       int diff = progress - prevProgress;
       if(diff > 0){
          //increase
          }
       else{
          //decrease
          }
        prevProgress = progress;
      }

});
