You can also implement it in this way, after setting recyclerview to adapter

final int duration = 10;
final int pixelsToMove = 263;
final Handler mHandler = new Handler(Looper.getMainLooper());

final Runnable SCROLLING_RUNNABLE = new Runnable() {
        @Override
        public void run() {
            recyclerView.smoothScrollBy(pixelsToMove, 0);
            mHandler.postDelayed(this, duration);
        }
    };

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            int lastItem = horizontalLayoutManager.findLastCompletelyVisibleItemPosition();
            if (lastItem == horizontalLayoutManager.getItemCount() - 1) {
                mHandler.removeCallbacks(SCROLLING_RUNNABLE);
                Handler postHandler = new Handler();
                postHandler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        quickTips.setAdapter(null);
                        quickTips.setAdapter(adapter);
                        mHandler.postDelayed(SCROLLING_RUNNABLE, 2000);
                    }
                }, 2000);
            }
        }
    });
    mHandler.postDelayed(SCROLLING_RUNNABLE, 2000);
