推荐答案

您可以使用WifiManager类提到的<一个href="http://stackoverflow.com/questions/2973290/check-wifi-and-gps-isconnected-or-not-in-android/2973334#2973334">here

you can use WifiManager class as mentioned here

编辑： 通过调用getConnectionInfo（）WifiManager类的功能，你会得到 WifiInfo 对象

by calling getConnectionInfo() function of WifiManager class you will get WifiInfo object

WifiInfo具有功能getBSSID（），它为您提供了连接AP的名称

WifiInfo has function getBSSID() which gives you connected AP's name

如果其为null，这意味着它没有连接到通过Wifi任何AP（无线未启用）

if its null that means it is not connected to any AP via Wifi ( Wifi is not enabled )

顺便说一句，同时寻找更多的信息，我发现这应该回答所有你对移动连接和WiFi连接问题

btw while looking for more info, i found this which should answer all your questions about mobile connectivity and wifi connectivity
