转到项目中的。project文件，并在名称标签中更改项目的名称

我有同样的错误，因为在工作空间中svn下还有一个项目，但有另一个名称。我把它移走了。

我刚找到的另一条路!

移动项目到其他文件夹，然后导入，如果需要，复制到工作区

我刚接触Eclipse和Android开发，这让我困扰了很长一段时间。以下是我做错的几件事，也许将来会对别人有所帮助:

I was downloading code examples and assuming project name would be the same as the folder name and was looking for that folder name in the project explorer, not finding it, re-importing it, then getting the error message it already existed in the workspace. Yeah. Not proud of that. Didn't click on 'Copy projects into Workspace' and then searched in vain through the workspace when it didn't appear in the project explorer BECAUSE The 'Add project to working sets' option in the Import Projects tab isn't working as far as I can tell, so was not appearing in the project explorer for the active working set (refresh made no difference). Adding project to the working set had to be done after successfully importing it.

这对我很管用。

文件>新建> Android项目>从现有资源创建项目

Location =要导入的项目的位置。

您将得到一条警告:“此目录中已存在一个Eclipse项目。 考虑使用File > Import > Existing Project代替。”但是你可以点击“Next”，项目就会被导入。

没有什么解决不了我的问题。这就是我解决的方法。

关闭IDE 从工作区中删除同名项目 启动IDE 清理所有项目(不确定这是否有帮助) >导入>现有项目 点击刷新按钮 导入项目

做. .
