方法一
public static String getLocalIpAddress() {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();Log.e("XXX", inetAddress.getHostAddress());if (!inetAddress.isLoopbackAddress() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) {return inetAddress.getHostAddress();}}}} catch (SocketException ex) {ex.printStackTrace();}return null;}
方法二
private static void getIpAddress() {new Thread() {@Overridepublic void run() {super.run();Socket socket = null;try {socket = new Socket("", 80);// 只有这个可以// 但是这个内网地址有没有外网的地址呢？Log.e("XXX", "socket : "+ socket.getLocalAddress().toString() + "\n");} catch (Exception e) {e.printStackTrace();} finally {if (socket != null) {try {socket.close();} catch (IOException e) {// TODO Auto-generated catch block e.printStackTrace();}}}}}.start();}
以上方法获取到的地址是大都是内网的IP地址，如需获取公网的IP地址，需要访问：
才可以,然后解析文本即可。
