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
