Xamarin ImageView 继承 class 无法调用 getContext

Question

```

public class MyImageView : ImageView
{

...

    public override void SetImageResource(int resId)
    {
        var inputBitmap = ProcessImage(ContextCompat.GetDrawable(getContext(), resId));
    }

...

}

```

在编译期间出现错误： Controls/MyImageView.cs(...): error CS0103: The name 'getContext' does not exist in the current context

我做错了什么？

Answer 1

Xamarin/C# 规范化将是 read-only 属性 命名：Context

public override void SetImageResource(int resId)
{
    var inputBitmap = ProcessImage(ContextCompat.GetDrawable(Context, resId));
}
