如何獲取設備網絡信息？ （Android）

Question

我當前正在處理的應用程序依賴於移動網絡，所以我的問題是，能否獲得設備上正在使用的當前移動網絡（例如3 UK，T-Mobile）？

另外，是否有獲取用戶手機號碼的方法？

謝謝你的幫助 （：

Answer 1

電話號碼：

        final TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
        final String phoneNumber = tm.getLine1Number();

網絡類型：

        // Check each connection type
        boolean connectionAvailable = false;
        ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);

        /**
         * WIFI
         */

        /** Check the connection **/
        NetworkInfo network = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

        // Make sure the network is available
        if(network != null && network.isAvailable() && network.isConnectedOrConnecting()) {
            connectionAvailable = true;
        }

        /**
         * 2G/3G
         */            
        /** Check the connection **/
        network = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

        // Show the right icon
        if(network != null &&
                (network.getSubtype() == TelephonyManager.NETWORK_TYPE_GPRS ||
                 network.getSubtype() == TelephonyManager.NETWORK_TYPE_EDGE)) {
            // 2G
        }
        else {
            // 3G
        }

        // Make sure the network is available
        if(network.isAvailable() && network.isConnectedOrConnecting()) {
            connectionAvailable = true;
        }

        /**
         * 4G
         */

        /** Check the connection **/
        network = cm.getNetworkInfo(ConnectivityManager.TYPE_WIMAX);

        // Make sure the network is available
        if(network != null && network.isAvailable() && network.isConnectedOrConnecting()) {
            connectionAvailable = true;
        }

您要查找的所有內容都在TelephonyManager 。 用法示例：

final TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
final String phoneNumber = tm.getLine1Number();

Answer 3

if (this.getPackageManager().hasSystemFeature(PackageManager.FEATURE_TELEPHONY)) {
    TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    String msisdn = telephonyManager.getLine1Number();
    String carrier = telephonyManager.getNetworkOperatorName();
}
