【移动开发】Android中WIFI开发总结(二)

简介:

  搞了好几天终于有点眉目了j_0063.gif,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

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
