1.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());

2.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;  }

获取android手机当前ip地址

public class NetWorkUtils {	/**	 * 检查网络是否可用	 * 	 * @param paramContext	 * @return	 */	public static boolean checkEnable(Context paramContext) {		boolean i = false;		NetworkInfo localNetworkInfo = ((ConnectivityManager) paramContext				.getSystemService("connectivity")).getActiveNetworkInfo();		if ((localNetworkInfo != null) && (localNetworkInfo.isAvailable()))			return true;		return false;	}	/**	 * 将ip的整数形式转换成ip形式	 * 	 * @param ipInt	 * @return	 */	public static String int2ip(int ipInt) {		StringBuilder sb = new StringBuilder();		sb.append(ipInt & 0xFF).append(".");		sb.append((ipInt >> 8) & 0xFF).append(".");		sb.append((ipInt >> 16) & 0xFF).append(".");		sb.append((ipInt >> 24) & 0xFF);		return sb.toString();	}	/**	 * 获取当前ip地址	 * 	 * @param context	 * @return	 */	public static String getLocalIpAddress(Context context) {		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();			// }			// }			// }			WifiManager wifiManager = (WifiManager) context					.getSystemService(Context.WIFI_SERVICE);			WifiInfo wifiInfo = wifiManager.getConnectionInfo();			int i = wifiInfo.getIpAddress();			return int2ip(i);		} catch (Exception ex) {			return " 获取IP出错鸟!!!!请保证是WIFI,或者请重新打开网络!/n" + ex.getMessage();		}		// return null;	}}

Android中获取本机ip地址和MAC地址

通过InetAddress.getLocalHost()得到始终是“127.0.0.1”,要想得到真正的网络ip地址要通过下面的方法:

首先新建一个工程,修改AndroidManifest.xml文件增加用户权限,如下:

复制代码 代码如下:

<uses-permission android:name="android.permission.INTERNET"/> //必写
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>//必写
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

主要函数代码如下:

// 得到本机ip地址 public String getLocalHostIp() {  String ipaddress = "";  try  {   Enumeration<NetworkInterface> en = NetworkInterface     .getNetworkInterfaces();   // 遍历所用的网络接口   while (en.hasMoreElements())   {    NetworkInterface nif = en.nextElement();// 得到每一个网络接口绑定的所有ip    Enumeration<InetAddress> inet = nif.getInetAddresses();    // 遍历每一个接口绑定的所有ip    while (inet.hasMoreElements())    {     InetAddress ip = inet.nextElement();     if (!ip.isLoopbackAddress()       && InetAddressUtils.isIPv4Address(ip         .getHostAddress()))     {      return ipaddress = "本机的ip是" + ":" + ip.getHostAddress();     }    }   }  }  catch (SocketException e)  {   Log.e("feige", "获取本地ip地址失败");   e.printStackTrace();  }  return ipaddress; } // 得到本机Mac地址 public String getLocalMac() {  String mac = "";  // 获取wifi管理器  WifiManager wifiMng = (WifiManager) getSystemService(Context.WIFI_SERVICE);  WifiInfo wifiInfor = wifiMng.getConnectionInfo();  mac = "本机的mac地址是:" + wifiInfor.getMacAddress();  return mac; }

Android 获取wifi的IP地址

WifiManager wifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//获取WifiManager  //检查wifi是否开启  if(!wifimanage.isWifiEnabled()) {   wifimanage.setWifiEnabled(true); }  WifiInfo wifiinfo= wifimanage.getConnectionInfo(); String ip=intToIp(wifiinfo.getIpAddress());  //将获取的int转为真正的ip地址,参考的网上的,修改了下  private String intToIp(int i) {  return (i & 0xFF)+ "." + ((i >> 8 ) & 0xFF)? + "." + ((i >> 16 ) & 0xFF) +"."+((i >> 24 ) & 0xFF );} 

OK,这样就好了吗?呵呵,别忘记加上权限 

复制代码 代码如下:

<uses -permission="" android:name="android.permission.ACCESS_WIFI_STATE"></uses> 
<uses -permission="" android:name="adnroid.permission.CHANGE_WIFI_STATE"></uses>

  总结:大家可以对比一下,Android 获取手机 IP 地址的方法,以免在编程的过程中造成不必要的问题.
