Android获取当前WIFI所有信息

Android获取当前WIFI所有信息：
我在这里提供一个获取WIFI信息的工具类，里边包含的方法有：
1、Android创建一个创建一个WifiLock
2、Android打开WIIF，Andorid关闭WIFI
3、用路由器或者热点的WIFI名称和WIFI密码配置一个连接WIFI的Config
4、连接一个已经配置好的WIFI
5、断开指定的WIFI
6、Andorid创建WIFI热点
7、获取当前连接的路由器的IP地址
8、获取手机在当前路由器中的局域网IP地址
9、获取当前连接的WIFI的名称
10、获取本机当前Wlan Mac地址
11、扫描当前WIFI，获得手机WIFI列表
