Although the current Android Gradle Plugin doesn't generate a R.javaanymore you can still inspect the corresponding class file (see Sergey V.`s answer).
尽管当前的 Android Gradle 插件不再生成R.java，但您仍然可以检查相应的类文件（请参阅 Sergey V. 的回答）。
However, if you (like probably in most cases) just want to look up the generated IDs for your resources, there is an easier way:
但是，如果您（可能在大多数情况下）只想为您的资源查找生成的 ID，则有一种更简单的方法：
In the project pane on the left hand side switch from Androidto Projectview using the drop-down at the top. Then navigate to app/build/intermediates/runtime_symbol_list/<insert build type here>/R.txt. This file lists all IDs generated by AGPduring the build process.
在左侧的项目窗格中，使用顶部的下拉菜单从Android切换到项目视图。然后导航到app/build/intermediates/runtime_symbol_list/<insert build type here>/R.txt. 该文件列出了 AGP在构建过程中生成的所有 ID。
