[Android] R.layout.main 找不到的问题

在Eclipse编译第一个Android程序的时候报出这样的错误：

setContentView(R.layout.main);  出错。

报告说：As of ADT 14, resource constants in library projects are no longer final.

但是，最终的原因和ADT 14没有什么关系，看下面的帖子：

If you fix imports before R.java has been generated for your project (before building it the first time) it will add the line:

import android.R;

which will override the local R.java that you are trying to reference.

Deleting that line resolved the errors for me.
