安卓 获取手机IP地址的实现代码

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：

<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 

<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.
