IntelliJ Idea不会在R.java中生成id

Question

我最近切换到IntelliJ Idea 12.

现在在android上创建了一个项目并立即遇到了一个问题:在R.java中没有生成id

重建项目没有帮助.

也许在IntelliJ Idea中有什么微妙之处我不知道？

错误:

R.java文件为空:

    /* This stub is for using by IDE only. It is NOT the R class actually packed into APK */
public final class R {
}

您所观察到的可能是Idea 12中的设计行为:

http://youtrack.jetbrains.com/issue/IDEA-99045

"这是IDEA 12的行为,它不会在gen文件夹中生成完整的R.java,它会在编译期间在IDEA的系统目录中生成它."

在你的情况下,请查看 ~/.IntelliJIdea12\system\compiler\YOUR_PROJECT_NAME.RANDOM_STRING\.generated\aapt\YOUR_PROJECT_NAME.RANDOM_STRING\production\package\R.java

此文件应该是最新的,它应包含您期望的所有ID.

它还应该通过某种内部的Idea魔术与Idea的自动完成功能,使用搜索功能等相结合.

空的R.java是正常的(虽然误导,Jetbrains打算改变这种行为).
