Android 擷取網絡類型（WIFI、CMNET、CMWAP）

下面這個方法用于擷取系統目前網絡類型：

1: public static int getNetworkType(Context context) {      

2:         ConnectivityManager connectivity = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);      

4:         if (connectivity != null) {       

5:             // 擷取網絡連接配接管理的對象      

6:             NetworkInfo info = connectivity.getActiveNetworkInfo();      

7:        

8:             if (info != null && info.isConnected()) {      

9:                 // 判斷目前網絡是否已經連接配接      

10:                 if (info.getState() == NetworkInfo.State.CONNECTED) {      

11:                     if (info.getTypeName().equals("WIFI")) {      

12:                         return MrDefines.NETTYPE_WIFI;      

13:                     } else {      

14:                         Cursor mCursor = context.getContentResolver().query(Uri.parse("content://telephony/carriers"),       

15:                                 new String[] {"name"}, "current=1", null, null);      

17:                         if(mCursor != null && mCursor.moveToFirst()){      

18:                             String name = mCursor.getString(0);      

20:                             if(name.equalsIgnoreCase("cmnet"))      

21:                                 return MrDefines.NETTYPE_CMNET;      

22:                             else if(name.equalsIgnoreCase("cmwap"))      

23:                                 return MrDefines.NETTYPE_CMWAP;      

24:                         }      

25:                     }      

26:                 }      

27:             }      

28:         }      

30:         return MrDefines.NETTYPE_UNKNOW;      

31:     }      

1: public static final int NETTYPE_WIFI=0,      

2:         NETTYPE_CMWAP=1,      

3:         NETTYPE_CMNET=2,      

4:         NETTYPE_UNKNOW=3;
