推荐答案

如果你只是想看看手机连接到网络，你可以尝试： ConnectivityManager.getAllNetworkInfo（），然后为每个网络适配器检查 networkinfo.getState（）。这应该告诉你，无论是连接与否。不过，我不知道是否有一种方法可以专门针对3G检查。

If you just want to see if the phone is connected to the network, you could try: ConnectivityManager.getAllNetworkInfo() and then for each network adapter check networkinfo.getState(). That should tell you whether it's connected or not. However, I'm not sure if there's a way to specifically check for 3G.
