android 获取当前手机的 dhcp 信息ip,server 等操作实例教程

wifimanager wifimanager = (wifimanager) getsystemservice(context.wifi_service);
assert wifimanager != null;
dhcpinfo dhcpinfo = wifimanager.getdhcpinfo();
logutils.w(dhcpinfo);
// ipaddr 172.20.161.205
// gateway 172.20.160.1
// netmask 255.255.254.0
// dns1 172.16.2.15
// dns2 172.16.2.16
// dhcp server 172.20.160.1
// lease 14400 seconds
int ip = dhcpinfo.serveraddress;
//此处获取ip为整数类型，需要进行转换
final string strip = inttoip(ip); // 172.20.160.1 ip --->< 27268268
logutils.w(strip + " ip --->< " + ip);

其中用到的方法：

private string inttoip(int i) {
 return (i & 0xff) + "." + ((i >> 8) & 0xff) + "." + ((i >> 16) & 0xff) + "."
+ ((i >> 24) & 0xff);
}
