今天终终终终终终终终终终终终终终终终终终终终终于找到了可以使用的能够调用的方法了，因为之前使用的Activity，Activity里面的传值方式有很大的不同，所以我按照之前的Activity类的继承关系重新谱写了它可以用的View类，当然这是为了和 ViewPager一起联合使用而制作的！
嘿嘿，小发以下代码，你们对比一看就知道有什么幺蛾子了！
Activity代码：

虽说会了以后就觉得挺简单的，我还是没有什么实际的感觉，毕竟~唉~还是对安卓程序发怵啊！花了这么多时间，才搞定这么一个小模块，感觉自己就是菜鸡啊！历程是艰苦的，结果是令人愉悦的，不对，接下来我们要针对用户的其他操作进行梳理和功能设计、实现了。
