Xamarin Forms -网格上的IsClipedToBounds不起作用。子视图仍在裁剪

using Xamarin.Forms;

namespace YourNamespace
{
    public class CustomGrid : Grid
    {
    }
}

using Android.Content;
using YourNamespace;
using YourNamespace.Droid;
using Xamarin.Forms;
using Xamarin.Forms.Platform.Android;

[assembly: ExportRenderer(typeof(CustomGrid), typeof(CustomGridRenderer))]
namespace YourNamespace.Droid
{
    public class CustomGridRenderer : VisualElementRenderer<Grid>
    {
        public CustomGridRenderer(Context context) : base(context)
        {
        }

        protected override void OnElementChanged(ElementChangedEventArgs<Grid> e)
        {
            base.OnElementChanged(e);

            if (e.NewElement != null)
            {
                SetClipChildren(true);
                SetClipToPadding(true);
            }
        }
    }
}

<local:CustomGrid IsClippedToBounds="True">
    <!-- 子视图内容 -->
</local:CustomGrid>
