我使用以下步骤解决了这个问题:

File ->导入 单击General，然后在Workspace中选择Existing Projects 单击Next 浏览项目目录 单击Finish。

这对我很有效

以下是我做的非常有效的方法。我只是在通用下导入了一个现有的项目，而不是导入一个android项目。

进入工作空间，将项目源代码文件夹移动到工作空间之外的另一个区域(如桌面)。确保在eclipse中删除了项目，然后在该目录中从source创建一个新项目。

您可以做的另一件事是尝试创建一个不同名称的项目(来自第一个项目的源)，这样工作空间将包含作为功能项目的新项目。然后，进入您的工作区目录，完全删除包含原始项目的文件夹，或者移动它。尝试再次从源代码加载项目，这次使用第二个项目，用正确的名称命名它。或者，您可以尝试将第二个项目重构为第一个项目的名称。

而不是从Android ->现有的Android代码导入工作空间，你必须使用通用->现有的项目到工作空间。这可能是一个解决方案。

今天我意外地解决了这个问题:

以下2个步骤可能不涉及，但不确定:

从(Eclipse菜单)调用*“/Window/Android SDK Manager”并更新a)“Android SDK Tools”“Android SDK平台工具”包 从Eclipse菜单“/Help/Check for Updates”调用并更新Eclipse。重新启动Eclipse。

以下步骤是必要的:

From eclipse menu "/File/Import/Android/Existing Android Code Into Workspace" Browse and select problematic project/or problematic projectS parent directory. Check "Copy projects into workspace". Check "Add projects into working sets". Press finish. [Optional scenario]: If project(s) and their containing folders have been renamed with the fully qualified package names then simply click on project node parent (where you see project package name instead of project's old name) in Eclipse and rename project with old name. Eclipse will rename folder too.

附注:在日蚀朱诺号上测试过。

Edit: Many times have passed since this answer and new Eclipse and Android SDK arrived. They have no much more problems during importing existing projects. The only thing one has to consider before importing is to move project folders(those ones one is willing to import) outside of eclipse workspace dir and then check checkboxes ("copy projects into working sets", "add projects into wokring sets") in import wizard dialog. Also I recommend doing this with latest Android SDK because it no more imports projects with dummy names and does not rename folders as it did in some custom cases.

这个选项解决了我的问题。
