导入R.（android） [英] importing R. (android)

问题描述

我已经搜索了Stack Overflow，因为我知道这是一个常见的问题，但没有一个解决方案对我有用。这包括清理我的项目，删除所有导入并删除项目并完全重新开始。

I have searched through Stack Overflow as I know this is a common question, but none of the solutions seemed to work for me. This included cleaning my project, deleting all imports and deleting the project and starting again entirely.

我正在使用专门用于Android的Eclipse（ADT捆绑软件）。

I am using the Eclipse specifically for android on mac (ADT bundle mac).

每当我创建一个新项目时，我在我的src文件夹中的错误就是
setContentView（R.layout.activity_main）;

Whenever I create a new project I have errors immediatley in my src folder on the line setContentView(R.layout.activity_main);

以及充气。

除了上述建议之外的任何建议？这是在我完成任何编程之前，所以无法理解错误。

Any suggestions other than those stated? It is literally before I have done any programming so cannot understand what is wrong.

编辑：修正。第二次下载SDK，这似乎修复了它。

Fixed. Downloaded the SDK a second time and this seems to have fixed it.
