在水平和垂直Recyclerview中滚动问题

Question

我有一个带ViewPager的MotionLayout。在由ViewPager托管的其中一个片段中，我有一个带有两个水平RecyclerViews的垂直RecyclerView。向上滚动工作正常，但是，当我尝试在内部RecyclerViews上水平滚动时，它不能很好地工作。它似乎试图垂直滚动（这里的问题视频：https://youtu.be/94rQ5Qkr2ew）我怀疑它与我正在使用的视图组合有关但我不完全确定如何修复它或弄清楚什么是错的。我在内部（水平）RecyclerView上尝试了这个，它似乎没有太大区别：

recyclerView.setOnTouchListener((v, event) -> {
        int action = event.getAction();
        View
        switch (action) {
            case MotionEvent.ACTION_CANCEL:
                v.getParent().requestDisallowInterceptTouchEvent(false);
            case MotionEvent.ACTION_UP:
                v.getParent().requestDisallowInterceptTouchEvent(false);
            case MotionEvent.ACTION_MOVE:
                v.getParent().requestDisallowInterceptTouchEvent(true);
                break;
        }
        return false;
    });

这是MotionLayout容器的布局文件：

它使用以下运动场景：

知道如何解决这个问题吗？或者至少改善它？
