Android 获取本机WIFI及3G网络IP

获取本机WIFI
privateStringgetLocalIpAddress(){
WifiManagerwifiManager=(WifiManager)getSystemService(WIFI_SERVICE);
WifiInfowifiInfo=wifiManager.getConnectionInfo();
//获取32位整型IP地址
intipAddress=wifiInfo.getIpAddress();

//返回整型地址转换成“*.*.*.*”地址
returnString.format("%d.%d.%d.%d",
(ipAddress&0xff),(ipAddress>>8&0xff),
(ipAddress>>16&0xff),(ipAddress>>24&0xff));
}

3G网络IP
publicstaticStringgetIpAddress(){

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()
&&inetAddressinstanceofInet4Address){
//if(!inetAddress.isLoopbackAddress()&&inetAddress
//instanceofInet6Address){
returninetAddress.getHostAddress().toString();
}
}
}
}catch(Exceptione){
e.printStackTrace();
}
returnnull;
