android - 为 Android 全屏制作 Xamarin 表单

Question

有没有办法让我在 Android 上的 Xamarin Forms 应用程序进入全屏或沉浸式模式？

我试过以下，状态栏上的所有控件都隐藏了，但状态栏本身仍在显示。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;

导航栏隐藏但状态栏不隐藏。

您可以通过在 Activity 属性中设置 theme 来做到这一点:

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

或者，如果您仅在特定 Activity 之后全屏显示，则在 Activity OnCreate 方法中设置以下标志:

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