在Recycler視圖中Android水平自動滾動

Question

我在列表中有兩個值，並使用Recycler視圖在水平列表視圖中顯示它。 在這里，我需要自動滾動水平列表無限制。 我嘗試使用以下代碼，但沒有結果。

Horizo​​ntalScrollView：添加新視圖時自動滾動到結束？

Answer 1

請在這里查看解決方案。 https://github.com/ritesh-bhavsar86/StockAutoScroll

首先創建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：

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

和

layoutmanager是LayoutManager，設置為recyclerview

Answer 2

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

This Works For me..
