获取手机IP地址的代码：

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(); if (!inetAddress.isLoopbackAddress()) { return inetAddress.getHostAddress().toString(); } } } }catch (SocketException e) { // TODO: handle exception Utils.log("WifiPreference IpAddress---error-" + e.toString()); } return null; }

但是在4.0 下 会出现类似fe80::b607:f9ff:fee5:487e的IP地址， 这个是IPV6的地址，我们需要获得是的IPV4的地址，所以要在上诉代码中加一个判断

InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())

完整代码如下：

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(); if (!inetAddress.isLoopbackAddress() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) { return inetAddress.getHostAddress().toString(); } } } }catch (SocketException e) { // TODO: handle exception Utils.log("WifiPreference IpAddress---error-" + e.toString()); } return null; }
