如何将公司徽标添加到NavigationPage TitleIcon？

using Android.Content;
using MyApp.Droid.Renderers;
using Xamarin.Forms;
using Xamarin.Forms.Platform.Android.AppCompat;

[assembly: ExportRenderer(typeof(NavigationPage), typeof(CustomNavigationPageRenderer))]
namespace MyApp.Droid.Renderers
{
    public class CustomNavigationPageRenderer : NavigationPageRenderer
    {
        public CustomNavigationPageRenderer(Context context) : base(context)
        {
        }

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

            if (e.NewElement != null)
            {
                var actionBar = ((FormsAppCompatActivity)Context).SupportActionBar;
                actionBar.SetLogo(Resource.Drawable.company_logo); // 设置公司徽标图像
                actionBar.SetDisplayUseLogoEnabled(true);
                actionBar.SetDisplayShowHomeEnabled(true);
            }
        }
    }
}
