当通过移动数据网络连接到互联网时,有没有简单的方法来获取我的手机的IP地址.为了获得WiFi IP地址,我正在使用以下简单的技术.
WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());

有没有类似上面的方法来获取移动数据网络的IP地址.
我使用了以下代码,但它返回了MAC地址,WiFi和蜂窝网络的IP地址,但我只对蜂窝IP地址感兴趣.
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();
Log.i("Sarao5",ipAddress);
}
}
}
} catch (SocketException ex) {}

使用我在我的应用程序中使用的以下代码 -
public static String getDeviceIPAddress(boolean useIPv4) {
try {
List<NetworkInterface> networkInterfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
for (NetworkInterface networkInterface : networkInterfaces) {
List<InetAddress> inetAddresses = Collections.list(networkInterface.getInetAddresses());
for (InetAddress inetAddress : inetAddresses) {
if (!inetAddress.isLoopbackAddress()) {
String sAddr = inetAddress.getHostAddress().toUpperCase();
boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
if (useIPv4) {
if (isIPv4)
return sAddr;
} else {
if (!isIPv4) {
// drop ip6 port suffix
int delim = sAddr.indexOf('%');
return delim < 0 ? sAddr : sAddr.substring(0, delim);
}
}
}
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
return "";
}

这是最简单的方法.
希望我的回答很有帮助.
