在StatusBar和MasterDetailPage Xamarin.Forms Android之间出现一个白条

public interface IStatusBarColorService
{
    void SetStatusBarColor(Color color);
}

[assembly: Dependency(typeof(StatusBarColorService))]
namespace YourNamespace.Droid
{
    public class StatusBarColorService : IStatusBarColorService
    {
        public void SetStatusBarColor(Color color)
        {
            if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
            {
                var androidColor = color.AddLuminosity(-0.1).ToAndroid();
                var window = MainActivity.Instance.Window;
                window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
                window.ClearFlags(WindowManagerFlags.TranslucentStatus);
                window.SetStatusBarColor(androidColor);
            }
        }
    }
}

var statusBarColorService = DependencyService.Get<IStatusBarColorService>();
statusBarColorService.SetStatusBarColor(Color.White);
