If there are any errors in the layout or any resource files there will be no build happening and the R.javafile will not be created.
如果布局或任何资源文件中有任何错误，则不会进行构建，R.java也不会创建文件。
Please solve the errors and then try to clean the project.
请解决错误，然后尝试清理项目。

Everytime you clean the project and it rebuilds, it imports
每次清理项目并重建时，它都会导入
import.android.R
导入.android.R
so, delete this import and remove all errors from xml files. It will work.
因此，删除此导入并从 xml 文件中删除所有错误。它会起作用。

Also if you tried to speed up eclipse and unchecked Preferences - > General -> Startup and Shutdown - > Android Development Toolkitcheck it back and restart eclipse, then R will generate automatically
此外，如果您尝试加速 eclipse 并且未选中 Preferences -> General -> Startup and Shutdown -> Android Development Toolkit检查并重新启动 eclipse，那么 R 将自动生成
