获取网络类型

Question

我一直试图重新审视当前的网络类型,但没有成功

当我说网络类型:我参考知道这个信息:如果类型是:NETWORK_TYPE_IDEN或NETWORK_TYPE_UMTS..等等..

我试着用:

NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();

要么

NetworkInfo mobNetInfo = connectivityManager.getNetworkInfo 
            (ConnectivityManager.TYPE_MOBILE); 

但没有成功..

我正在做这个因为我想知道当前网络是否是IDEN,或者当前网络是否通过wifi连接..

我讨厌神奇的数字:

/**
 * You need to add:
 * 
 * <pre>
 *     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 * </pre>
 * 
 * in your AndroidManifest.xml.
 */
private String networkType() {
    TelephonyManager teleMan = (TelephonyManager)
            getSystemService(Context.TELEPHONY_SERVICE);
    int networkType = teleMan.getNetworkType();
    switch (networkType) {
        case TelephonyManager.NETWORK_TYPE_1xRTT: return "1xRTT";
        case TelephonyManager.NETWORK_TYPE_CDMA: return "CDMA";
        case TelephonyManager.NETWORK_TYPE_EDGE: return "EDGE";
        case TelephonyManager.NETWORK_TYPE_EHRPD: return "eHRPD";
        case TelephonyManager.NETWORK_TYPE_EVDO_0: return "EVDO rev. 0";
        case TelephonyManager.NETWORK_TYPE_EVDO_A: return "EVDO rev. A";
        case TelephonyManager.NETWORK_TYPE_EVDO_B: return "EVDO rev. B";
        case TelephonyManager.NETWORK_TYPE_GPRS: return "GPRS";
        case TelephonyManager.NETWORK_TYPE_HSDPA: return "HSDPA";
        case TelephonyManager.NETWORK_TYPE_HSPA: return "HSPA";
        case TelephonyManager.NETWORK_TYPE_HSPAP: return "HSPA+";
        case TelephonyManager.NETWORK_TYPE_HSUPA: return "HSUPA";
        case TelephonyManager.NETWORK_TYPE_IDEN: return "iDen";
        case TelephonyManager.NETWORK_TYPE_LTE: return "LTE";
        case TelephonyManager.NETWORK_TYPE_UMTS: return "UMTS";
        case TelephonyManager.NETWORK_TYPE_UNKNOWN: return "Unknown";
    }
    throw new RuntimeException("New type of network");
}

这对我来说可以检查网络类型......

TelephonyManager teleMan =  
            (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
int networkType = teleMan.getNetworkType();

switch (networkType)
{
case 7:
    textV1.setText("1xRTT");
    break;      
case 4:
    textV1.setText("CDMA");
    break;      
case 2:
    textV1.setText("EDGE");
    break;  
case 14:
    textV1.setText("eHRPD");
    break;      
case 5:
    textV1.setText("EVDO rev. 0");
    break;  
case 6:
    textV1.setText("EVDO rev. A");
    break;  
case 12:
    textV1.setText("EVDO rev. B");
    break;  
case 1:
    textV1.setText("GPRS");
    break;      
case 8:
    textV1.setText("HSDPA");
    break;      
case 10:
    textV1.setText("HSPA");
    break;          
case 15:
    textV1.setText("HSPA+");
    break;          
case 9:
    textV1.setText("HSUPA");
    break;          
case 11:
    textV1.setText("iDen");
    break;
case 13:
    textV1.setText("LTE");
    break;
case 3:
    textV1.setText("UMTS");
    break;          
case 0:
    textV1.setText("Unknown");
    break;
}

要获得网络类型(我认为您在谈论无线或移动),您可以使用此代码段:

ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

//mobile
State mobile = conMan.getNetworkInfo(0).getState();

//wifi
State wifi = conMan.getNetworkInfo(1).getState();

然后像这样使用它:

if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State.CONNECTING) {
    //mobile
} else if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING) {
    //wifi
}

要获得移动网络的类型,我会尝试TelephonyManager#getNetworkType或NetworkInfo#getSubtypeName

我正在使用这个功能:

public String get_network()
       {Activity act=(Activity)context;
        String network_type="UNKNOWN";//maybe usb reverse tethering
        NetworkInfo active_network=((ConnectivityManager)act.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
        if (active_network!=null && active_network.isConnectedOrConnecting())
           {if (active_network.getType()==ConnectivityManager.TYPE_WIFI)
               {network_type="WIFI";
               }
            else if (active_network.getType()==ConnectivityManager.TYPE_MOBILE)
                 {network_type=((ConnectivityManager)act.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo().getSubtypeName();
                 }
           }
        return network_type;
       }
