推荐答案

您需要将Android的支持库添加到您的项目。

You need to add the Android Support library to your project.

http://developer.android.com/tool​​s/support-library/ setup.html

为了使用一个支持库，您必须在开发环境中修改应用程序的项目的类路径依赖。

"In order to use a Support Library, you must modify your application's project's classpath dependencies within your development environment."
