Xamarin - SignaturePad BackgroundImageView 问题

Question

无法正常工作 - 我一定是遗漏了什么：

signaturePad2.BackgroundImageView = new ImageView(Context)
{
   Id = GenerateId(this),
   LayoutParameters = new RelativeLayout.LayoutParams (RelativeLayout.LayoutParams.MatchParent, RelativeLayout.LayoutParams.MatchParent)
};

signaturePad2.AddView(BackgroundImageView);
signaturePad2.BackgroundImage = MyGlobals.FileNameOfPhotoTaken;

Answer 1

BackgroundImage 的类型是 ImageSource

padView.BackgroundImage = ImageSource.FromUri(new Uri(
