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：
publicstaticStringgetLocalIpAddress(){
try{
for(Enumeration<NetworkInterface>en=NetworkInterface.getNetworkInterfaces();en.hasMoreElements();){
NetworkInterfaceintf=en.nextElement();
for(Enumeration<InetAddress>enumIpAddr=intf
.getInetAddresses();enumIpAddr.hasMoreElements();){
InetAddressinetAddress=enumIpAddr.nextElement();
if(!inetAddress.isLoopbackAddress()){
returninetAddress.getHostAddress().toString();
}
}
}
}catch(SocketExceptione){
//TODO:handleexception
Utils.log("WifiPreferenceIpAddress---error-"+e.toString());
}
returnnull;
}
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：
publicstaticStringgetLocalIpAddress(){
try{
for(Enumeration<NetworkInterface>en=NetworkInterface.getNetworkInterfaces();en.hasMoreElements();){
NetworkInterfaceintf=en.nextElement();
for(Enumeration<InetAddress>enumIpAddr=intf
.getInetAddresses();enumIpAddr.hasMoreElements();){
InetAddressinetAddress=enumIpAddr.nextElement();
if(!inetAddress.isLoopbackAddress()&&InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())){
returninetAddress.getHostAddress().toString();
}
}
}
}catch(SocketExceptione){
//TODO:handleexception
Utils.log("WifiPreferenceIpAddress---error-"+e.toString());
}
returnnull;
}
获取android手机当前ip地址
publicclassNetWorkUtils{
/**
*检查网络是否可用
*
*@paramparamContext
*@return
*/
publicstaticbooleancheckEnable(ContextparamContext){
booleani=false;
NetworkInfolocalNetworkInfo=((ConnectivityManager)paramContext
.getSystemService("connectivity")).getActiveNetworkInfo();
if((localNetworkInfo!=null)&&(localNetworkInfo.isAvailable()))
returntrue;
returnfalse;
}
/**
*将ip的整数形式转换成ip形式
*
*@paramipInt
*@return
*/
publicstaticStringint2ip(intipInt){
StringBuildersb=newStringBuilder();
sb.append(ipInt&0xFF).append(".");
sb.append((ipInt>>8)&0xFF).append(".");
sb.append((ipInt>>16)&0xFF).append(".");
sb.append((ipInt>>24)&0xFF);
returnsb.toString();
}
/**
*获取当前ip地址
*
*@paramcontext
*@return
*/
publicstaticStringgetLocalIpAddress(Contextcontext){
try{
//for(Enumeration<NetworkInterface>en=NetworkInterface
//.getNetworkInterfaces();en.hasMoreElements();){
//NetworkInterfaceintf=en.nextElement();
//for(Enumeration<InetAddress>enumIpAddr=intf
//.getInetAddresses();enumIpAddr.hasMoreElements();){
//InetAddressinetAddress=enumIpAddr.nextElement();
//if(!inetAddress.isLoopbackAddress()){
//returninetAddress.getHostAddress().toString();
//}
//}
//}
WifiManagerwifiManager=(WifiManager)context
.getSystemService(Context.WIFI_SERVICE);
WifiInfowifiInfo=wifiManager.getConnectionInfo();
inti=wifiInfo.getIpAddress();
returnint2ip(i);
}catch(Exceptionex){
return"获取IP出错鸟!!!!请保证是WIFI,或者请重新打开网络!\n"+ex.getMessage();
}
//returnnull;
}
}
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-permissionandroid:name="android.permission.INTERNET"/>//必写 <uses-permissionandroid:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permissionandroid:name="android.permission.CHANGE_NETWORK_STATE"></uses-permission> <uses-permissionandroid:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>//必写 <uses-permissionandroid:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
主要函数代码如下：
//得到本机ip地址
publicStringgetLocalHostIp()
{
Stringipaddress="";
try
{
Enumeration<NetworkInterface>en=NetworkInterface
.getNetworkInterfaces();
//遍历所用的网络接口
while(en.hasMoreElements())
{
NetworkInterfacenif=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())
{
InetAddressip=inet.nextElement();
if(!ip.isLoopbackAddress()
&&InetAddressUtils.isIPv4Address(ip
.getHostAddress()))
{
returnipaddress="本机的ip是"+"："+ip.getHostAddress();
}
}
}
}
catch(SocketExceptione)
{
Log.e("feige","获取本地ip地址失败");
e.printStackTrace();
}
returnipaddress;
}
//得到本机Mac地址
publicStringgetLocalMac()
{
Stringmac="";
//获取wifi管理器
WifiManagerwifiMng=(WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfowifiInfor=wifiMng.getConnectionInfo();
mac="本机的mac地址是："+wifiInfor.getMacAddress();
returnmac;
}
Android获取wifi的IP地址
WifiManagerwifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//获取WifiManager
//检查wifi是否开启
if(!wifimanage.isWifiEnabled()){
wifimanage.setWifiEnabled(true);
}
WifiInfowifiinfo=wifimanage.getConnectionInfo();
Stringip=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
privateStringintToIp(inti){
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.
