搞了好几天终于有点眉目了
，这里接着总结一下Android中WiFi的使用，在前面（http://smallwoniu.blog.51cto.com/3911954/1334951）我们已经简单了解了Wifi实际操作中所用到的几个主要类，今天就剖析一个WIFI搜索、创建、关闭、连接及一些简单的动画的综合案例。
首先，我们还是看一下我们项目的框架
MainActivity类：（处理wifi消息，加载UI）

貌似有点长。。。简单说明一下：
1.首先，初始化主界面（xml有些复杂，慢慢理一下就好了，不是什么大问题）接下来，处理三个重要的按钮事件：右上角的搜索wifi按钮、中间创建或关闭热点按钮、对话框中确定按钮。处理前两者事件时，需关注当前wifi状态，若为占用，需弹出提醒对话框来根据当前WiFi操作（WFOperateEnum类中定义好了）事件，来创建、关闭、搜索等具体事务。
2.之所以定义广播接收者，是为了监听当wifi状态发生变化时，能够及时更新界面

说明：监听系统wifi状态变化，内部定义了一个事件处理接口，当wifi状态发生变化时，让其实现类去发送消息更新界面。

点击连接，实现客户连接，此时他们将处于同一网段内，接下来就可以自己实现传输数据，操控等一系列操作了。 在下一篇中我会继实现一个基于wif热点的多人聊天室，希望能帮助到大家！
