android 获取网络类型名称2G 3G 4G wifi

首先工程Manifest文件要引用：

1 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />2 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

//获取网络服务

 1 public static String getNetworkTypeName(Context context) { 2      if (context != null) { 3           ConnectivityManager connectMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 4           if (connectMgr != null) { 5                   NetworkInfo info = connectMgr.getActiveNetworkInfo(); 6                   if (info != null) { 7                        switch (info.getType()) { 8                             case ConnectivityManager.TYPE_WIFI: 9                                   return "WIFI";10                             case ConnectivityManager.TYPE_MOBILE:11                                   return getNetworkTypeName(info.getSubtype());12                        }13                   }14           }15      }16      return getNetworkTypeName(TelephonyManager.NETWORK_TYPE_UNKNOWN);17 }

//网络型号

 1 public static String getNetworkTypeName(int type) { 2      switch (type) { 3           case TelephonyManager.NETWORK_TYPE_GPRS: 4                return "GPRS"; 5           case TelephonyManager.NETWORK_TYPE_EDGE: 6                return "EDGE"; 7           case TelephonyManager.NETWORK_TYPE_UMTS: 8                return "UMTS"; 9           case TelephonyManager.NETWORK_TYPE_HSDPA:10                return "HSDPA";11           case TelephonyManager.NETWORK_TYPE_HSUPA:12                return "HSUPA";13           case TelephonyManager.NETWORK_TYPE_HSPA:14                return "HSPA";15           case TelephonyManager.NETWORK_TYPE_CDMA:16                return "CDMA";17           case TelephonyManager.NETWORK_TYPE_EVDO_0:18                return "CDMA - EvDo rev. 0";19           case TelephonyManager.NETWORK_TYPE_EVDO_A:20                return "CDMA - EvDo rev. A";21           case TelephonyManager.NETWORK_TYPE_EVDO_B:22                return "CDMA - EvDo rev. B";23           case TelephonyManager.NETWORK_TYPE_1xRTT:24                return "CDMA - 1xRTT";25           case TelephonyManager.NETWORK_TYPE_LTE:26                return "LTE";27           case TelephonyManager.NETWORK_TYPE_EHRPD:28                return "CDMA - eHRPD";29           case TelephonyManager.NETWORK_TYPE_IDEN:30                return "iDEN";31           case TelephonyManager.NETWORK_TYPE_HSPAP:32                return "HSPA+";33           default:34                return "UNKNOWN";35      }36 }

调用：

 1 @Override 2     public void onClick(View view) { 3         // TODO Auto-generated method stub 4         switch (view.getId()) { 5         case R.id.btn_main: 6              String type =getNetworkTypeName(context); 7              if (type!=null){ 8                  if ( type.equals("GPRS") || type.equals("EGDE") ) 9                    type ="2G";10                  else      if (type.equals("CDMA"))11                        type ="电信 2G";12                  else if (type.equals("EVDO"))13                        type ="电信 3G";14                  else if (type.equals("LTE"))15                        type ="电信 4G";16                  else if (type.equals("HSDPA") ||type.equals("UMTS")  )17                        type ="3G";       18                  19              }20             btn_main.setText(type);21             break;22         }

注：

移动或联通的3G为UMTS或HSDPA，移动和联通的2G为GPRS或EGDE，电信的2G为CDMA，电信的3G为EVDO，电信4G LTE
