開始之前，首先说一下什么叫一键桥接，所谓一键桥接，就是点击一下。就能够对所连接的路由器进行网络中继设置。以实现路由器能够通过已有的无线路由器进行网络訪问。

那么实现这个功能有几种方法呢？能够说有非常多种。仅仅要能够和路由网关进行通信即可。一般能够选择。Socket通信，Http通信。对于Http通信能够选择HttpClient, HttpURLConnection等。在本文中，为了实现的方便。我们选择android的特性之中的一个，webkit。也即是使用WebView控件来实现一键桥接

一、WebView是什么

二、看我实现

package com.leo.switchrouter;

import android.app.Service;

import android.content.Context;

import android.content.Intent;

import android.content.SharedPreferences;

import android.os.Handler;

import android.os.IBinder;

import android.os.Message;

import android.os.SystemClock;

import android.text.TextUtils;

import android.webkit.HttpAuthHandler;

import android.webkit.WebSettings;

import android.webkit.WebView;

import android.webkit.WebViewClient;

import android.widget.Toast;

三、总结

本文中所使用的方法，是投机取巧了，通过JS代码非常easy的操作配置页面。然后通过WebView操作JS代码，非常easy实现想要实现的功能。
