我有一个带有 ViewPager 的 MotionLayout。在 ViewPager 托管的片段之一中，我有一个带有两个水平 RecyclerView 的垂直 RecyclerView。垂直滚动效果很好，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 ）我怀疑这与我正在使用的视图组合有关，但我不完全确定如何去做修复它或找出问题所在。我已经在内部（水平） RecyclerView 上尝试过这个，它似乎并没有太大的区别：
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：

</MotionScene>知道如何解决这个问题吗？或者至少改进一下？
