Reduce speed of smooth scroll in scroll view

Question

I have a scroll View. I performed smooth-scroll.using smoothScrollBy().It all works fine, but I want to change the duration of the smooth-scroll. Smooth-scroll happens very fast

Answer 1

Try the following code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
{
    ValueAnimator realSmoothScrollAnimation = 
        ValueAnimator.ofInt(parentScrollView.getScrollY(), targetScrollY);
    realSmoothScrollAnimation.setDuration(500);
    realSmoothScrollAnimation.addUpdateListener(new AnimatorUpdateListener()
    {
        @Override
        public void onAnimationUpdate(ValueAnimator animation)
        {
            int scrollTo = (Integer) animation.getAnimatedValue();
            parentScrollView.scrollTo(0, scrollTo);
        }
    });

    realSmoothScrollAnimation.start();
}
else
{
    parentScrollView.smoothScrollTo(0, targetScrollY);
}
