Answer 1

我有一个非常相似的问题。

似乎资源文件R已被删除。就我而言，它在我创建Google Maps Activity 时消失了。

尝试:
构建->清理项目
清理gradle文件

或者:
文件->使缓存无效
然后将项目与Gradle文件同步

快去看看这些是否有用。
我发现创建一个新项目并复制并粘贴“旧”项目中的代码效果最好。这确实需要一些时间，因为您必须再次创建所有xml文件和Java类，但是考虑到我浏览了Web多少小时才能找到修复程序，因此创建新项目仅花费了大约30分钟，当然这取决于根据您的项目规模。只要确保(如果继续进行，然后复制并粘贴代码)，就可以确保您不会意外地将包名称从“旧”项目复制到新项目中(如果新项目的名称不同)。

祝好运!
