问题小结（8）-获取wifi网关和ip

[java]
package com.schogini.dhcp;

import android.content.Context;
import android.net.DhcpInfo;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.text.format.Formatter;

public class CheckWireLess {
     private static WifiManager wifiManager;
     private static DhcpInfo dhcpInfo;
     private static WifiInfo wifiInfo;

     //ip获取
     public static String getIp(Context context){
      wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
      dhcpInfo = wifiManager.getDhcpInfo();
      wifiInfo = wifiManager.getConnectionInfo();
      //wifiInfo返回当前的Wi-Fi连接的动态信息
      int ip = wifiInfo.getIpAddress();
      return "wifi_ip:"+FormatIP(ip);
     }

     //网关获取
     public static String getGateWay(Context context){
         wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
         dhcpInfo = wifiManager.getDhcpInfo();

      //dhcpInfo获取的是最后一次成功的相关信息，包括网关、ip等
      return "dh_ip:"+FormatIP(dhcpInfo.ipAddress)+"\n"+"dh_gateway"+FormatIP(dhcpInfo.gateway);
     }

     // IP地址转化为字符串格式
     public static String FormatIP(int IpAddress) {
      return Formatter.formatIpAddress(IpAddress);
      }

}
package com.schogini.dhcp;

import android.content.Context;
import android.net.DhcpInfo;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.text.format.Formatter;

public class CheckWireLess {
private static WifiManager wifiManager;
private static DhcpInfo dhcpInfo;
private static WifiInfo wifiInfo;

//ip获取
     public static String getIp(Context context){
      wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
      dhcpInfo = wifiManager.getDhcpInfo();
      wifiInfo = wifiManager.getConnectionInfo();
      //wifiInfo返回当前的Wi-Fi连接的动态信息
      int ip = wifiInfo.getIpAddress();
   return "wifi_ip:"+FormatIP(ip);
     }

     //网关获取
     public static String getGateWay(Context context){
    wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
         dhcpInfo = wifiManager.getDhcpInfo();

   //dhcpInfo获取的是最后一次成功的相关信息，包括网关、ip等
      return "dh_ip:"+FormatIP(dhcpInfo.ipAddress)+"\n"+"dh_gateway"+FormatIP(dhcpInfo.gateway);
     }

     // IP地址转化为字符串格式
public static String FormatIP(int IpAddress) {
   return Formatter.formatIpAddress(IpAddress);
   }

}

所以在使用的时候要注意ip获取方式的选择，两种方式是有区别的，上述代码经过本地手机测试。
