Obtenir la largeur de l'écran sur l'API Niveau 30 (Android 11): GetDefaultDisplay () et GetMétrictrics () sont maintenant obsolètes. Que devrions-nous utiliser à la place?

Question

Je calcule actuellement la largeur de l'écran comme ceci:

public static int getScreenWidth(@NonNull Context context) {
    DisplayMetrics displayMetrics = new DisplayMetrics();
    ((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    return displayMetrics.widthPixels;
}

Puisque ces 2 fonctions (getDefaultDisplay () et getsmetrictrics ()) sont maintenant obsolètes, que devrions-nous utiliser à la place?

@RequiresApi(20)
inline val Fragment.windowHeight: Int
    get() {
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
            val metrics = requireActivity().windowManager.currentWindowMetrics
            val insets = metrics.windowInsets.getInsets(WindowInsets.Type.systemBars())
            metrics.bounds.height() - insets.bottom - insets.top
        } else {
            val view = requireActivity().window.decorView
            val insets = WindowInsetsCompat.toWindowInsetsCompat(view.rootWindowInsets, view).getInsets(WindowInsetsCompat.Type.systemBars())
            resources.displayMetrics.heightPixels - insets.bottom - insets.top
        }
    }

@RequiresApi(20)
inline val Fragment.windowHeight: Int
    get() {
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
            val metrics = requireActivity().windowManager.currentWindowMetrics
            val insets = metrics.windowInsets.getInsets(WindowInsets.Type.systemBars())
            metrics.bounds.width() - insets.left - insets.right
        } else {
            val view = requireActivity().window.decorView
            val insets = WindowInsetsCompat.toWindowInsetsCompat(view.rootWindowInsets, view).getInsets(WindowInsetsCompat.Type.systemBars())
            resources.displayMetrics.widthPixels - insets.left - insets.right
        }
    }

Cela nécessite androidx.core version 1.5.x
