安卓开发获取手机运营商网络类型

获取手机运营商网络类型的方法

权限配置

在 AndroidManifest.xml 中添加读取手机状态的权限：

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

使用 TelephonyManager 获取网络类型

通过 TelephonyManager 的 getNetworkType() 方法获取原始网络类型值，再映射为可读的字符串。

示例代码

import android.content.Context;
import android.telephony.TelephonyManager;
public class NetworkUtils {
    public static String getNetworkType(Context context) {
        TelephonyManager telephonyManager = 
            (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (telephonyManager == null) {
            return "Unknown";
        }
        int networkType = telephonyManager.getNetworkType();
        switch (networkType) {
            case TelephonyManager.NETWORK_TYPE_NR: return "5G/NR";
            case TelephonyManager.NETWORK_TYPE_LTE: return "4G/LTE";
            case TelephonyManager.NETWORK_TYPE_HSPAP: return "3G+";
            case TelephonyManager.NETWORK_TYPE_HSDPA: return "3G";
            case TelephonyManager.NETWORK_TYPE_HSUPA: return "3G";
            case TelephonyManager.NETWORK_TYPE_UMTS: return "3G";
            case TelephonyManager.NETWORK_TYPE_EVDO_0: return "CDMA EVDO Rev.0";
            case TelephonyManager.NETWORK_TYPE_EVDO_A: return "CDMA EVDO Rev.A";
            case TelephonyManager.NETWORK_TYPE_EVDO_B: return "CDMA EVDO Rev.B";
            case TelephonyManager.NETWORK_TYPE_EHRPD: return "eHRPD";
            case TelephonyManager.NETWORK_TYPE_HSPA: return "3G";
            case TelephonyManager.NETWORK_TYPE_HSPAP: return "3G+";
            case TelephonyManager.NETWORK_TYPE_IDEN: return "iDEN";
            case TelephonyManager.NETWORK_TYPE_LTE_CA: return "4G+"; // LTE Carrier Aggregation
            case TelephonyManager.NETWORK_TYPE_UNKNOWN: return "Unknown";
            default: return "Unknown";
        }
    }
}

相关问题与解答

问题1：如何监听网络类型的实时变化？

解答：
可通过 PhoneStateListener 监听网络变化，示例如下：

TelephonyManager telephonyManager = 
    (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
PhoneStateListener listener = new PhoneStateListener() {
    @Override
    public void onDataConnectionStateChanged(int state, int networkType) {
        super.onDataConnectionStateChanged(state, networkType);
        String type = getNetworkType(networkType); // 自定义方法映射网络类型
        Log.d("NetworkChange", "Current Type: " + type);
    }
};
telephonyManager.listen(listener, PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);

问题2：如何判断设备是否正在使用移动数据（而非WiFi）？

解答：
结合 ConnectivityManager 和 TelephonyManager 判断：

import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public boolean isUsingMobileData(Context context) {
    ConnectivityManager cm = 
        (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    if (activeNetwork != null && activeNetwork.isConnected()) {
        // 检查是否是移动网络类型（非WiFi）
        return activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE;
    }
    return false;
}
