How to change seek bar progress colour according to its progress?

问题

I want to create a custom seekbar, whose progress bar's colour change between red and blue as the user changes the progress of the bar.

I have tried it but its only changing the background colour not the progress bar color.

seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

            public void onStopTrackingTouch(SeekBar seekBar) {
                // TODO Auto-generated method stub

            }

            public void onStartTrackingTouch(SeekBar seekBar) {
                // TODO Auto-generated method stub

            }

            public void onProgressChanged(SeekBar seekBar, int progress,
                    boolean fromUser) {


                seekBar.setBackgroundColor(Color.RED + progress);

            }
        });

There are a lot of way to do this, I'll tell the simple way. You can set the color of progressBackground like this:

seekBar.getProgressDrawable().setColorFilter("<Color you wish>", PorterDuff.Mode.MULTIPLY);

If your api level 21, you can use getProgressBackgroundTintList or getProgressBackgroundTintMode().
