android - 获取网络类型

Question

我一直在尝试检索当前的网络类型，但没有成功

当我说网络类型时:我指的是知道这个信息:如果类型是:NETWORK_TYPE_IDEN 或 NETWORK_TYPE_UMTS..等等..

我尝试使用:

NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();

或

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

但没有成功..

我这样做是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:

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+";
