Seekbar's thumb on click

I would like to register a clickable event on the seekbar's thumb in order to trigger an event when the user has cliked it. Is it possible?

Combining zwebie and Nermeens answers to the proper solution:

seekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    private int mProgressAtStartTracking;
    private final int SENSITIVITY;

    @Override
    public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
        // handle progress change
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
        mProgressAtStartTracking = seekBar.getProgress();
    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
        if(Math.abs(mProgressAtStartTracking - seekBar.getProgress()) <= SENSITIVITY){
            // react to thumb click
        }
    }
});

So this really fires only on thumb click, not on thumb move and not on click on other parts of the seekbar.

You can adjust sensitivity, because sometimes a click already moves the thumb a little bit and allowing little changes while still clicking is less frustrating. A good value here depends on the size of the seekbar and the max value it can have. For me 3 worked well on a full-width seekbar with 50 max on a portrait layout.

I was able to achieve this in the following way:

seekBar.setOnTouchListener(new OnTouchListener() 
{
    @Override
    public boolean onTouch(View v, MotionEvent event) 
    {
        if(event.getAction() == MotionEvent.ACTION_MOVE)
        {
            changedPosition = true;
            seekBar.setProgress(seekBar.getProgress());
            return false;
        }
        else if (event.getAction() == MotionEvent.ACTION_UP)
        {
            if(!changedPosition)
            {
                  //do action here
            }
        }
   }

hope this helps

我这样做：

pagesSeekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { //listener
        @Override
        public void onStopTrackingTouch(final SeekBar seekBar) {
            //add your event here
        }

        @Override
        public void onStartTrackingTouch(final SeekBar seekBar) {
        }

        @Override
        public void onProgressChanged(final SeekBar seekBar, final int progress, final boolean fromUser) {
                updateControls(progress, false);
        }
    });
