将recyclerView旋转90度

Question

我有一个屏幕，其中上半部分由cameraView覆盖，下半部分是其中包含一个片段的slidePanel，该片段包含一个recyclerView。我只希望屏幕是纵向的，但是当方向更改为横向时，对象应在其位置旋转90度。我正在旋转包含Fragment并包含RecyclerView的FrameLayout。对象旋转完美，但是问题是recyclerView表现得很奇怪。当frameLayout旋转到90度RecyclerView而不是在横向模式下垂直滚动时，它将在水平滚动时滚动。

下面是我的XML，其中包含已旋转到90度的FrameLayout。

我的问题是，当recyclerView旋转到90度时，如何更改其滚动行为。请找到随附的屏幕截图以供参考。

如果您看到所附的屏幕截图，则可以看到当我旋转框架容器时，它旋转了其中的对象recylerView，但在横向时它像在纵向模式下一样滚动。
