Android RecyclerView快速滚动，持续减速

我想更改我的水平回收视图的平滑滚动位置行为

• 一开始应该很快，我已经做到了
• 不断地降低速度，最终平滑地滚动到目标元素。这是我没有做到的

过度使用calculateTimeForDeceleration方法对我没有帮助，这听起来应该会减慢速度

CustomLinearLayoutManager代码：

CustomLinearLayoutManager layoutManager = new CustomLinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false, 0.4f);
galleryView = findViewById(R.id.recyclerview);
galleryView.setLayoutManager(layoutManager);

自定义LinearLayoutManager：

public class CustomLinearLayoutManager extends LinearLayoutManager {
    private final float factor;


    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout, float factor) {
        super(context, orientation, reverseLayout);
        this.factor = factor;
    }

    @Override
    public void smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state, int position) {

        final LinearSmoothScroller linearSmoothScroller = new LinearSmoothScroller(recyclerView.getContext()) {

            @Override
            public PointF computeScrollVectorForPosition(int targetPosition) {
                return CustomLinearLayoutManager.this.computeScrollVectorForPosition(targetPosition);
            }

            @Override
            protected float calculateSpeedPerPixel(DisplayMetrics displayMetrics) {
                return super.calculateSpeedPerPixel(displayMetrics) * factor;
            }

            @Override
            protected int calculateTimeForScrolling(int dx) {
                return super.calculateTimeForScrolling(dx*1);
            }

        };

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

    @Override
    public void scrollToPosition(int position) {
        super.scrollToPosition(position);
    }
}

如何持续降低滚动速度
