Android Intent传递对象和ArrayList

         以前做项目的时候，需要Intent 传递复杂类型，例如：数组，ArrayList类型，传递类对象，今天抽空写了个例子，方便以后用的时候查询！有问题可以留言；

                   程序主界面：                                     点击list按钮传递数据：    

                  点击parcelable传递数据：                                             点击serializable传递数据：

下面看代码：

一、MainAcitivty。java类的代码：
