无论如何让我在 Android 上的 Xamarin Forms 应用程序进入全屏或沉浸式模式？

我尝试了以下方法，状态栏上的所有控件都被隐藏了，但状态栏本身仍然显示。任何帮助，请

var newUiOptions = (int)SystemUiFlags.LayoutStable;

newUiOptions |= (int)SystemUiFlags.LayoutHideNavigation;
newUiOptions |= (int)SystemUiFlags.LayoutFullscreen;
newUiOptions |= (int)SystemUiFlags.HideNavigation;
newUiOptions |= (int)SystemUiFlags.Fullscreen;
newUiOptions |= (int)SystemUiFlags.Immersive;
//newUiOptions |= (int)SystemUiFlags.ImmersiveSticky;

decorView.SystemUiVisibility = (StatusBarVisibility)newUiOptions;

导航栏是隐藏的，但不是状态栏。

您可以通过设置属性theme来做到这一点：Activity

[Activity (Label = "@string/app_name", MainLauncher = true, Theme = "@android:style/Theme.Black.NoTitleBar.Fullscreen")]

或者，如果您仅在特定活动之后全屏，则在活动OnCreate方法中设置以下标志：

this.Window.AddFlags(WindowManagerFlags.Fullscreen);
this.Window.ClearFlags(WindowManagerFlags.Fullscreen);

protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);

            // Get our game view from the layout resource,
            // and attach the view created event to it
            CCGameView gameView = (CCGameView)FindViewById(Resource.Id.GameView);
            gameView.ViewCreated += LoadGame;
            gameView.SystemUiVisibility = (StatusBarVisibility)(SystemUiFlags.HideNavigation
                | SystemUiFlags.Fullscreen
                | SystemUiFlags.LayoutFullscreen
                | SystemUiFlags.LayoutHideNavigation
                | SystemUiFlags.Immersive);


        }
