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 下會出現(xiàn)類似fe80::b607:f9ff:fee5:487e的IP地址，這個是IPV6的地址，我們需要獲得是的IPV4的地址，所以要在上訴代碼中加一個判斷

InetAddressUtils.isIPv4Address(inetAddress.getHostAddress());

2.完整代碼如下：

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; 
 }

Android中獲取本機(jī)ip地址和MAC地址

通過InetAddress.getLocalHost()得到始終是“127.0.0.1”，要想得到真正的網(wǎng)絡(luò)ip地址要通過下面的方法：

首先新建一個工程，修改AndroidManifest.xml文件增加用戶權(quán)限，如下：

復(fù)制代碼代碼如下:

<uses-permission android:name="android.permission.INTERNET"/> //必寫

<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>//必寫

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

主要函數(shù)代碼如下：

// 得到本機(jī)ip地址
 public String getLocalHostIp()
 {
  String ipaddress = "";
  try
  {
   Enumeration<NetworkInterface> en = NetworkInterface
     .getNetworkInterfaces();
   // 遍歷所用的網(wǎng)絡(luò)接口
   while (en.hasMoreElements())
   {
    NetworkInterface nif = en.nextElement();// 得到每一個網(wǎng)絡(luò)接口綁定的所有ip
    Enumeration<InetAddress> inet = nif.getInetAddresses();
    // 遍歷每一個接口綁定的所有ip
    while (inet.hasMoreElements())
    {
     InetAddress ip = inet.nextElement();
     if (!ip.isLoopbackAddress()
       && InetAddressUtils.isIPv4Address(ip
         .getHostAddress()))
     {
      return ipaddress = "本機(jī)的ip是" + "：" + ip.getHostAddress();
     }
    }

   }
  }
  catch (SocketException e)
  {
   Log.e("feige", "獲取本地ip地址失敗");
   e.printStackTrace();
  }
  return ipaddress;

 }

 // 得到本機(jī)Mac地址
 public String getLocalMac()
 {
  String mac = "";
  // 獲取wifi管理器
  WifiManager wifiMng = (WifiManager) getSystemService(Context.WIFI_SERVICE);
  WifiInfo wifiInfor = wifiMng.getConnectionInfo();
  mac = "本機(jī)的mac地址是：" + wifiInfor.getMacAddress();
  return mac;
 }

Android 獲取wifi的IP地址

WifiManager wifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//獲取WifiManager 
 
//檢查wifi是否開啟 
 
if(!wifimanage.isWifiEnabled()) { 
　　wifimanage.setWifiEnabled(true); 
} 
 
WifiInfo wifiinfo= wifimanage.getConnectionInfo(); 
String ip=intToIp(wifiinfo.getIpAddress()); 
 
//將獲取的int轉(zhuǎn)為真正的ip地址,參考的網(wǎng)上的，修改了下 
 
private String intToIp(int i) {
　　return (i & 0xFF)+ "." + ((i >> 8 ) & 0xFF)? + "." + ((i >> 16 ) & 0xFF) +"."+((i >> 24 ) & 0xFF );
}

OK,這樣就好了嗎？呵呵，別忘記加上權(quán)限

復(fù)制代碼代碼如下:

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

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

總結(jié)：大家可以對比一下，Android 獲取手機(jī) IP 地址的方法，以免在編程的過程中造成不必要的問題.
