我有一个FragmentActivity与其中的一些片段。当我从我正在拍摄的片段（片段A）中，将手机放在肖像位置，到我在代码setOrientation（）中设置的下一个片段（片段B）到横向时，我握住黑色屏幕在将手机变为风景之前，纵向显示的手机和布局不会显示在第二个片段上。我的印象是，无论你如何拿着手机，当你做setRequestedOrientation（）应该有力地表明您提供使用setRequestedOrientation时获得黑屏（）
视觉布局：

代码：
MainActivity这持有的方向变化：
// Set Orientation of the Activity.
public void setOrientation(int sensor) {
if (sensor == 1) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
} else if (sensor == 2) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
} else if (sensor == 3) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
} else if (sensor == 4) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
} else if (sensor == 5) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
}
弗拉加：
个@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Set the orientation to be in portrait and landscape.
((MainActivity) getActivity()).setOrientation(1);
...
}
FragB：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Set the orientation to be in landscape.
((MainActivity) getActivity()).setOrientation(5);
...
}
