RecyclerView Smooth Scroll animation

I had implemented a smooth scroll animation for ViewPager using OnjectAnimator. Now, i am trying to do the same for a recyclerView but the scroll animation is abrupt. Here is my animation using ObjectAnimator for a viewpager. It produces a snap animation to demonstrate the scroll capability of the viewpager.

ObjectAnimator objectAnimator = ObjectAnimator
    .ofFloat(new PagerHintMovement(-10, viewPager), "progress", -1f, 1f);

objectAnimator.setInterpolator(new AccelerateInterpolator());
objectAnimator.setDuration(1500);
objectAnimator.setRepeatCount(1);
objectAnimator.setRepeatMode(ValueAnimator.REVERSE);
objectAnimator.addListener(new Animator.AnimatorListener() {
  @Override
  public void onAnimationStart(Animator animation) {
    Log.i(TAG, "Animation: Starting fake drag on view pager.");
    viewPager.beginFakeDrag();
  }

  @Override
  public void onAnimationEnd(Animator animation) {
    Log.i(TAG, "Animation: Ending fake drag on view pager.");
    viewPager.endFakeDrag();
    viewPager.setCurrentItem(viewPager.getCurrentItem());
  }

  @Override
  public void onAnimationCancel(Animator animation) {
    viewPager.setCurrentItem(viewPager.getCurrentItem());
  }

  @Override
  public void onAnimationRepeat(Animator animation) {

    if (VERSION.SDK_INT >= VERSION_CODES.JELLY_BEAN_MR2) {
      if (animation.getInterpolator() instanceof AccelerateInterpolator) {
        animation.setInterpolator(new DecelerateInterpolator());
      } else {
        animation.setInterpolator(new AccelerateInterpolator());
      }
    }
  }
});
objectAnimator.setStartDelay(1000);
objectAnimator.start();

Any suggestions on how to achieve the same for a recyclerView ?

If you are not satisfied with default RecyclerView.smoothScrollToPosition(int) you will need to do some class overrides.

Smooth scroll in RecyclerView is triggered by calling
LayoutManager.startSmoothScroll(RecyclerView.SmoothScroller) on its current layoutManager.

You are free to override LayoutManager and provide custom RecyclerView.SmoothScroller implementation - preferably by extending RecyclerView.LinearSmoothScroller.
