在片段中将方向锁定为横向

Question

My app has navigation set up and it is a single activity app. Fragments are linked like this:

MainFragment -> GameFragment

MainFragment -> GameSetupFragment -> GameFragment

What I need to accomplish: Depending on settings, GameFragment sometimes should be locked in the landscape mode. When I did this in an activity, I wrote a line of code:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

What can I do if I use fragments? Is there a way to tell the fragment owner (ie the activity) to switch the orientation?

Answer 1

假设您知道您的片段已附加到活动，您可以在片段中调用requireActivity()来获取您的活动：

requireActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
