Smooth Progress Bar Animation

If you change progress value each time by 1 (for example from 45 to 46) you won’t see the animation. You’d better change progress by 100 points (or maybe other), for this you just need to multiply your max value by 100 and each progress value to 100 too. For example:

    private void setProgressMax(ProgressBar pb, int max) {
        pb.setMax(max * 100);
    }

    private void setProgressAnimate(ProgressBar pb, int progressTo) 
    {
        ObjectAnimator animation = ObjectAnimator.ofInt(pb, "progress", pb.getProgress(), progressTo * 100);
        animation.setDuration( 500);
        animation.setAutoCancel( true);
        animation.setInterpolator( new DecelerateInterpolator());
        animation.start();
    }
