I have fixed this problem and sharing my solution here so if anyone who also faced this problem can work with it.

public void smoothScrollToUserSelectedPosition(DiscreteScrollView discreteScrollView, int imgIndex) {
        try {
            final RecyclerView.Adapter<?> adapter = discreteScrollView.getAdapter();
            int destination = imgIndex;
            if (adapter instanceof InfiniteScrollAdapter) {
                destination = ((InfiniteScrollAdapter<?>) adapter).getClosestPosition(destination);
            }
            discreteScrollView.smoothScrollToPosition(destination);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Call Like this:

new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                smoothScrollToUserSelectedPosition(discreteScrollView, imgIndex);
            }
        }, 100);
