//获取ip地址    public static String getIpForNet() {          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) {                      Log.e("WifiPreference IpAddress", ex.toString());                  }                               return null;      }      public static String getIpForWifi(Context context){        WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);         WifiInfo wifiInfo = wifiManager.getConnectionInfo();        int ipAddress = wifiInfo.getIpAddress();        String ip = Formatter.formatIpAddress(ipAddress);        return ip;    }

有的时候可能只获取ipv4的地址，所以上面的判断需要加上

inetAddress instanceof Inet4Address
