如何找到Android设备的LAN IP地址？ [英] How to find LAN ip address of android device?

问题描述

如果设备的无线连接，我假设该设备由路由器上运行的DHCP具有局域网IP地址分配presumably。

If wifi of device is connected, I assume the device has an LAN IP address assigned presumably by a dhcp running on a router.

如何才能找到它有什么WiFi接口的LAN IP地址（而不是外部IP）？

How can find it what's the LAN ip address (not the external ip) on the wifi interface ?

谢谢，

推荐答案

的NetworkInterface 将帮助你：

String ipAddress = null;
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()) {
                ipAddress = inetAddress.getHostAddress().toString();
            }
        }
    }
} catch (SocketException ex) {}
