不在Wi-Fi上时的内部IP地址

Question

我使用它来连接到Wi-Fi时获取内部IP：

            WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();

            int ipv4intAddress = wifiInfo.getIpAddress();
            tempView = (TextView) findViewById(R.id.textViewIPv4Int2);
            tempView.setText(myNetworkOperations.iptoDecimal(ipv4intAddress));

在移动设备或其他类型的连接上有没有类似的简单方法来获取IP？

您可以尝试使用以下代码：

try {
    for (Enumeration < NetworkInterface > en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
        NetworkInterface intf = en.nextElement();
        for (Enumeration < InetAddress > enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
            InetAddress inetAddress = enumIpAddr.nextElement();
            if (!inetAddress.isLoopbackAddress()) {
                return inetAddress.getHostAddress().toString();
            }
        }
    }
} catch (SocketException ex) {
    return "ERROR Obtaining IP";
}
return "No IP Available";
