Setting the orientation for only 1 fragment in my activity while the rest is in portrait

Question

My app needs to be in portrait mode so I set it in the manifest by:

android:screenOrientation=\"portrait\"

But I just recently added anothe

Answer 1

ok after i almost blew my head off this worked for me with jetpack navigation components fragments

so this is the base fragment class

abstract class BaseFragment : Fragment(){   

var rotated = false

fun rotate() {
        val currentOrientation = activity?.resources?.configuration?.orientation //this is diffrent from  Configuration.ORIENTATION_LANDSCAPE
        Log.e("currentOrientation--->",currentOrientation.toString())

        if (currentOrientation != null) {
            if (currentOrientation !=  Configuration.ORIENTATION_LANDSCAPE) {
                activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
            }else{
                rotated=true
            }
        }else{
            //impossible
            activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
        }
    }


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

}

and i put this in any fragment i wish it to be landscaped

override fun onStart() {
    super.onStart()
    rotate()
}
