在Android中对Wifi操作，android本身提供了一些有用的包，在android.net.wifi包下面。简单介绍一下：

大致可以分为四个主要的类ScanResult,wifiConfiguration,WifiInfo,WifiManager

(1)ScanResult，主要是通过wifi 硬件的扫描来获取一些周边的wifi 热点的信息。

(2)wifiConfiguration 在我们连通一个wifi 接入点的时候，需要获取到的一些信息。大家可以跟我们有线的设备进行对比一下。

(3)WifiInfo 在我们的wifi 已经连通了以后，可以通过这个类获得一些已经连通的wifi 连接的信息获取当前链接的信息，这里信息就比较简单了

(4)wifiManager 这个不用说，就是用来管理我们的wifi 连接，这里已经定义好了一些类，可以供我们使用。这里来说相对复杂，里面的内容比较多，但是通过字面意思，我们还是可以获得很多相关的信息。这个类里面预先定义了许多常量，我们可以直接使用，不用再次创建。

-Operate on Wifi in Android , android itself provides some useful package, android.net.wifi package below . A brief introduction:

Can be divided into four main classes ScanResult, wifiConfiguration, WifiInfo, WifiManager

(1) ScanResult, mainly through wifi hardware scan to get some information about the surrounding wifi hotspot .

(2) wifiConfiguration in our connectivity when a wifi access point , you need to get some information . We can tell our wired devices compare .

(3) WifiInfo have in our wifi connectivity after , you can get some of this class have been connected wifi connection information for the current link information , where information is relatively simple

(4) wifiManager this goes without saying , is used to manage our wifi connection , where some classes have been defined , can be for our use. Here is relatively complex , which more content , but through the literal meaning , we can still get a lot of relevant information. This class is a lot of pre-defined constan
