Turn off auto rotation in fragment

I have a PictureFragment which I use to show a picture in fullscreen when selecting it from my thumbnail. It works fine, but when I rotate my smartphone, the picture also rotates and gets scaled very ugly sothat its height is now its actual width and so on. How can I turn off the rotation for this fragment? I've read always how to do it for a whole activity but for the rest of the activity this runs in I want to keep the auto rotation. Or, if this is also easy possible, how can I manage to scale the picture sensefully on rotation to keep its aspect ratio?

@SuppressLint("SourceLockedOrientationActivity")
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
    //Rest of the code
}

override fun onDestroyView() {
    super.onDestroyView()
    activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED
}

Without overriding onDestroyView() all your fragments of activity will have locked orientation that you defined in one of your fragments this way activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT

Simple solution using Googles Navigation Conponents:

In your Activity:

navController.addOnDestinationChangedListener { _, destination, _ ->
        if (destination.id == R.id.fragmentB) {
            requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
        } else if (requestedOrientation != ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR) {
            requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR
        }
    }

This logic would lock the screen orientation of "fragmentB" (Id resource from your navigation graph) to portrait.

navController is an instance of androidx.navigation.NavController

Add in manifest

android:configChanges="keyboardHidden|orientation"

add in your fragment

@Override
public void onConfigurationChanged(@NonNull Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    if (getActivity() != null) {          
            if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
                getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            } else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
                getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            }
        }       
}

In your Fragment call inside onResume to lock to portrait:

getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

then in onPause to unlock orientation:

getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);

OBS! For the sake, use if(getActivity != null) before using this methods.
