首先创建可运行文件:

first create runnable:

final int duration = 10;
final int pixelsToMove = 30;
private final Handler mHandler = new Handler(Looper.getMainLooper());
private final Runnable SCROLLING_RUNNABLE = new Runnable() {

    @Override
    public void run() {
        rv_autoScroll.smoothScrollBy(pixelsToMove, 0);
        mHandler.postDelayed(this, duration);
    }
};

然后在setadapter()到recyclerView之后，使用以下命令:

then after setadapter() to the recyclerView use following:

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

rv_autoScroll是recyclerview

rv_autoScroll is recyclerview

和

layoutmanager是设置为recyclerview的LayoutManager

layoutmanager is LayoutManager which set to recyclerview
