无法在Visual Studio Xamarin中打开设计器视图

Question

我在其他PC上有一个现有项目，但是，当我将项目文件移动到另一台计算机上时，项目本身无法在xaml文件中显示拖放视图，而是显示代码视图而不是拖放视图，应该如何我要做的是让我看到设计师的观点吗？

Answer 1

Are you using the Core Framework of xamarin or Xamarin Forms ? (I'm asking because you are talking about xaml files instead of xml)

If you are using the Core Framework juste have a look to this link coming from the xamarin documentation :

https://developer.xamarin.com/guides/android/user_interface/designer_overview/designer_walkthrough/

One last thing, instead of copying the files use a version management tools if is not the case (like github or bitbucket)

Answer 2

The installed Android SDK is probably too old. Consider updating it.
