java获取网络类型的方法

本文实例讲述了java获取网络类型的方法。分享给大家供大家参考。具体如下：

/**** 
* 获取网络类型 
* 
* @param context 
* @return 
*/ 
public static string getnettype(context context) { 
try { 
connectivitymanager connectmgr = (connectivitymanager) context 
.getsystemservice(context.connectivity_service); 
networkinfo info = connectmgr.getactivenetworkinfo(); 
if (info == null) { 
return ""; 
} 
if (info.gettype() == connectivitymanager.type_wifi) { 
return "wifi"; 
} else if (info.gettype() == connectivitymanager.type_mobile) { 
if (info.getsubtype() == telephonymanager.network_type_cdma) { 
return "cdma"; 
} else if (info.getsubtype() == telephonymanager.network_type_edge) { 
return "edge"; 
} else if (info.getsubtype() == telephonymanager.network_type_evdo_0) { 
return "evdo0"; 
} else if (info.getsubtype() == telephonymanager.network_type_evdo_a) { 
return "evdoa"; 
} else if (info.getsubtype() == telephonymanager.network_type_gprs) { 
return "gprs"; 
} 
/* 
* else if(info.getsubtype() == 
* telephonymanager.network_type_hsdpa){ return "hsdpa"; }else 
* if(info.getsubtype() == telephonymanager.network_type_hspa){ 
* return "hspa"; }else if(info.getsubtype() == 
* telephonymanager.network_type_hsupa){ return "hsupa"; } 
*/ 
else if (info.getsubtype() == telephonymanager.network_type_umts) { 
return "umts"; 
} else { 
return "3g"; 
} 
} else { 
return ""; 
} 
} catch (exception e) { 
return ""; 
} 
} 

希望本文所述对大家的java程序设计有所帮助。
