Answer 1

我找到了解决问题的方法。

I got my solution from here

void CreateNotification(string title, string desc)
        {
            //Create notification
            var notificationManager = GetSystemService(Context.NotificationService) as 
                 NotificationManager;

            //Create an intent to show ui
            var uiIntent = new Intent(this, typeof(MainActivity));

            //Create the notification
            var notification = new Notification(Resource.Drawable.Icon, title);
            //var notification = new Notification(Android.Resource.Drawable.SymActionEmail,title);

            //Auto cancel will remove the notification once the user touches it
            notification.Flags = NotificationFlags.AutoCancel;

            //Set the notification info
            //we use the pending intent, passing our ui intent over which will get called
            //when the notification is tapped.
            notification.SetLatestEventInfo(this,
                title, desc, PendingIntent.GetActivity(this, 0, uiIntent, 0));

            //Show the notification
            notificationManager.Notify(1, notification);
        }

正如Documentation所述，在您致电SetSmallIcon()之前，需要使用builder.Build()设置一个小图标。这很可能是您的问题所在，因为您的代码似乎没有其他任何问题。
