Question

根据错误消息，导致foo.barscratch.ItemView错误，因为它不存在。问题是，它不应该存在。我不知道引用它的是什么。

最初我从另一个项目复制了这个文件，并将其重命名为foo.bar.BazItemView。

没有什么应该调用foo.barscratch.ItemView但是在我的项目中搜索字符串“scratch”或单词“ItemView”没有任何结果。这里发生了什么？我只是想摆脱任何调用这个类的东西。

Answer 1

根据异常情况，您似乎在第3行的布局（xml）文件中引用了一些自定义视图（ItemView类）。如果一切正常，请再次检查您的布局文件。

Answer 2

不确定..但您可以尝试检查该特定视图的内存管理。

在渲染视图时，当内存超出特定限制时，可能会出现膨胀异常。

OR

检查您尝试显示的自定义视图是否不存在。

请告诉我这是否适合您，以便我可以将这些内容留在我的脑海中供将来参考。

干杯！

Answer 3

简短回答：重新加载项目。

我再次搜索了ItemView这个词，并在workspace.xml文件中找到了一个对ItemView.java的引用。我评论了该线路，Android Studio问我是否要重新加载该项目。我说了可以。错误消失了。

顺便说一下，我之后对该行进行了注释，重新加载后，错误没有返回。

我怀疑这可能是Android Studio的一个错误。有一次，我将ItemView.java从一个旧项目拖到这个项目中。弹出一个对话框，询问是否链接到外部项目。我点击取消，但是尽管取消了取消，IDE尝试进行一些重构并报告两次只读错误。

感谢所有提供帮助的人！
