c# - 使用 xamarin 在默认锁定屏幕上的 Android Activity

Question

我想知道如何在 xamarin 的 C# 代码中添加 WindowManager 的 LayoutParams 标志。

例如，我们可以通过下面给出的代码在 Android 中做到这一点。

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON|
            WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD|
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED|
            WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

像这样:

namespace SampleCode
{
    [Activity (Label = "SampleCode", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity : Activity
    {

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

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

            Window.AddFlags(WindowManagerFlags.KeepScreenOn|
                WindowManagerFlags.DismissKeyguard|
                WindowManagerFlags.ShowWhenLocked|
                WindowManagerFlags.TurnScreenOn);       
        }
    }
}
