我有一个Activity和几个片段（它们被称为fragmentA和fragmentB）。现在fragmentA需要有纵向和横向布局。fragmentB必须保持肖像。Activity在onCreate方法中显示fragmentA。我尝试了这个链接：https://stackoverflow.com/a/53864286/15351040在fragmentA中添加了以下代码。

override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        activity?.let {
            it.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_SENSOR
        }
        return super.onCreateView(inflater, container, savedInstanceState)
    }
override fun onDestroyView() {
        super.onDestroyView()
        activity?.let {
            it.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED
        }
    }

并在fragmentB中添加了以下代码。

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    activity?.let {
        it.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
    }
    return super.onCreateView(inflater, container, savedInstanceState)
}
override fun onDestroyView() {
    super.onDestroyView()
    activity?.let {
        it.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED
    }
}

但是当我打开fragmentB时，fragmentA再次打开，而不是fragmentB。当activity的requestOrientation被改变时，可能会调用它的onCreate。当fragmentA是肖像时，它工作得很好，但不是风景。
我现在该怎么办？
