Android动态获取当前手机IP地址

public static String getIPAddress(Context context) {
NetworkInfo info = ((ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
if (info != null && info.isConnected()) {
if (info.getType() == ConnectivityManager.TYPE_MOBILE) {//当前使用2G/3G/4G网络
try {
//Enumeration en=NetworkInterface.getNetworkInterfaces();
for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) {
NetworkInterface intf = en.nextElement();
for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {
return inetAddress.getHostAddress();
}
}
}
} catch (SocketException e) {
e.printStackTrace();
}

} else if (info.getType() == ConnectivityManager.TYPE_WIFI) {//当前使用无线网络
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
String ipAddress = intIP2StringIP(wifiInfo.getIpAddress());//得到IPV4地址
return ipAddress;
}
} else {
//当前无网络连接,请在设置中打开网络
}
return null;
}

/**
* 将得到的int类型的IP转换为String类型
*
* @param ip
* @return

public static String intIP2StringIP(int ip) {
return (ip & 0xFF) + "." +
((ip >> 8) & 0xFF) + "." +
((ip >> 16) & 0xFF) + "." +
(ip >> 24 & 0xFF);
