Android Studio无法正确显示xml文件

Question

Android Studio突然在xml文件中显示自动生成的代码。我曾尝试使缓存/重新启动无效，但不能解决问题。我也尝试过清理项目并重建它，但是它也不起作用。即使一切都可以在编辑器中正确显示，例如sublime文字。这是我的android studio显示的xml文件之一的代码。

`/ *自动生成的文件。请勿修改。* *该类由* gradle插件自动从找到的资源数据中生成。*请勿手工修改。* /

Answer 1

只需将现有项目复制到另一个文件夹并用android studio重新打开该项目，它就会再次正常显示。

这个问题今天发生在我身上，当我打开一个 java 文件时，android studio 向我展示了 XML 文件。

Answer 2

您的布局 xml 文件或 AndroidManifest.xml 文件中应该存在错误。我注意到只有一些文件在波浪线下有红色，请仔细检查它们，特别是其中包含自定义小部件，例如lotteryanimationview.
