获取网络类型

时间：2010-05-27 08:05:22

标签： android

我一直在尝试检索当前的网络类型，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..

我试图使用：

NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();

或

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..

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";

    }
    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;
}

答案 2 :(得分：14)

要获取网络类型（我认为您在讨论wifi或移动设备），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
}

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

我正在使用此功能：

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;
       }

另外，在AndroidManifest.xml中添加以下必需的权限。

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

否则，由于安全性异常，您将在获取ConnectivityManager句柄时遇到应用程序崩溃。

在TelephonyManager中的Android SDK中，有一个与移动数据类有关的隐藏方法，通过API级别跟踪此方法的更改以使android的定义保持最新可能很有用。他们

根据我的经验......最好使用Android培训指南来完成这些类型的工作。当您使用这些类时，很容易获得空指针异常，当您首次打开应用程序然后应用程序崩溃时尝试检测这些连接时，这种情况尤其糟糕。

您可以使用ConnectivityManager检查您是否确实已连接到互联网，如果是，则建立了什么类型的连接：

您可以使用ConnectivityManager确定有效的无线电：

更好的用途是：

    NetworkInfo activeNetworkInfo = ((ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
    if (activeNetworkInfo == null) return false;
    switch (activeNetworkInfo.getType()) {
        case ConnectivityManager.TYPE_WIFI:
            return true;
    }
//        public static final int TYPE_BLUETOOTH = 7;
//        public static final int TYPE_DUMMY = 8;
//        public static final int TYPE_ETHERNET = 9;
//        public static final int TYPE_MOBILE = 0;
//        public static final int TYPE_MOBILE_DUN = 4;
//        /** @deprecated */
//        @Deprecated
//        public static final int TYPE_MOBILE_HIPRI = 5;
//        /** @deprecated */
//        @Deprecated
//        public static final int TYPE_MOBILE_MMS = 2;
//        /** @deprecated */
//        @Deprecated
//        public static final int TYPE_MOBILE_SUPL = 3;

//        public static final int TYPE_WIFI = 1;
//        public static final int TYPE_WIMAX = 6;

您想要定义和处理的其他类型取决于您......

对于那些想要字符串标识符的人，最好使用：

activeNetworkInfo.getTypeName()
activeNetworkInfo.getSubtypeName()

如果您想知道它是哪种网络，可以使用：

private String getNetworkClass() {
    // network type
    TelephonyManager mTelephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
    int networkType = mTelephonyManager != null ? mTelephonyManager.getNetworkType() : 0;
    switch (networkType) {
        case TelephonyManager.NETWORK_TYPE_UNKNOWN:
            return "Unknown network";
        case TelephonyManager.NETWORK_TYPE_GSM:
            return " GSM";
        case TelephonyManager.NETWORK_TYPE_CDMA:
        case TelephonyManager.NETWORK_TYPE_1xRTT:
        case TelephonyManager.NETWORK_TYPE_IDEN:
            return " 2G";
        case TelephonyManager.NETWORK_TYPE_GPRS:
            return " GPRS (2.5G)";
        case TelephonyManager.NETWORK_TYPE_EDGE:
            return " EDGE (2.75G)";
        case TelephonyManager.NETWORK_TYPE_UMTS:
        case TelephonyManager.NETWORK_TYPE_EVDO_0:
        case TelephonyManager.NETWORK_TYPE_EVDO_A:
        case TelephonyManager.NETWORK_TYPE_EVDO_B:
            return " 3G";
        case TelephonyManager.NETWORK_TYPE_HSPA:
        case TelephonyManager.NETWORK_TYPE_HSDPA:
        case TelephonyManager.NETWORK_TYPE_HSUPA:
            return " H (3G+)";
        case TelephonyManager.NETWORK_TYPE_EHRPD:
        case TelephonyManager.NETWORK_TYPE_HSPAP:
        case TelephonyManager.NETWORK_TYPE_TD_SCDMA:
            return " H+ (3G++)";
        case TelephonyManager.NETWORK_TYPE_LTE:
        case TelephonyManager.NETWORK_TYPE_IWLAN:
            return " 4G";
        default:
            return " 4G+";
