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
