Android 谷歌开发者提供的交互式图表示例，显示eclipse错误

我只是导入项目。我在res和src文件夹中得到错误符号。我决定从现有代码创建一个项目。我仍然得到错误。我得到的错误不是所有项目，而是一些项目，主要是所有谷歌示例：

我重新启动了eclipse。我的计算机，清除了所有项目。不知道如何解决这个问题

谢谢

编辑：我需要提到的是，一些项目在没有错误的情况下成功运行（之前），现在显示错误。这些项目工作得很好/

因此我尝试更改主题和java文件。没有任何效果。我所要做的就是：

转到项目属性（在项目上单击鼠标右键）

转到Android目标，单击最新

好的，申请吧，给你D

你的项目在以前的工作区工作吗？是的。以前的项目可以工作。即使是我从开发网站下载的谷歌示例也不能工作。有些项目可以工作。我没有任何线索。如果你使用新的工作区，请确保你的sdk路径正确。我检查了它。很好。问题是有些项目可以运行。其他的就是不行。bt他们以前是这样的。ohhh+1用于回答你的问题可能是项目u或导入u可能需要一些库或缺少某些内容转到属性并检查一下java构建路径
