mRecyclerView.smoothScrollToPosition(position);這個函數(shù)用于平滑的滑動到指定的位置，如果還想控制平滑滑動的速度的話，mRecyclerView沒有提供相關api，查看源碼，你可以發(fā)現(xiàn)最后調用的是LayoutManager的smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state, int position) ，所以關鍵就是這里，需要重寫LayoutManager的這個方法，實例代碼：

    @Override
    public void smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state, int position) {
        LinearSmoothScroller smoothScroller =
                new LinearSmoothScroller(recyclerView.getContext()) {
                    // 返回：滑過1px時經(jīng)歷的時間(ms)。
                    @Override
                    protected float calculateSpeedPerPixel(DisplayMetrics displayMetrics) {
                        return 150f / displayMetrics.densityDpi;
                    }
                };

        smoothScroller.setTargetPosition(position);
        startSmoothScroll(smoothScroller);
    }
