如何解析java。android中的lang.ClassNotFoundException？

Question

我正在尝试运行一个应用程序。我发现了一个错误：

JAVAlang.ClassNotFoundException:未找到类“android.view.SquareImageView”

但我已经在android的java文件夹中创建了SquareImageView类。但我还是犯了这个错误。

部分错误：

Answer 1

在视图XML文件中，您使用SquareImageView作为类引用，而不使用完整的包名。由于没有包含完整的包名，Anroid假定SquareImageView位于android中。查看包，但找不到该类。您需要在视图XML文件中添加完整的包名。
