❶ 我想修改ANDROID的wifi系统，我用什么技术容易实现呢

你的登录了我理解为就可以上网了。 你现在可以随便访问一个URL如网络的，然后获取重定向的URL，如果还是网络的，说明登录了。 如果不是网络，跳转到了你指定的域名了说明就没有登录，然后现在你 用post 重新发一个URL 里面包含你的用户名和密码就好了啊

❷ android 怎么判断是否wifi

AndroidAPI有提供获取网络状态以及网络类型的接口，代码也很简单

NetworkInfonetworkInfo=(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE).getActiveNetworkInfo();

if(networkInfo!=null&&networkInfo.isConnected()){

if(networkInfo.getType()==ConnectivityManager.TYPE_WIFI)//这个状态就是wifi

//TODO

}elseif(networkInfo.getType()==ConnectivityManager.TYPE_MOBILE)

{

//TODO

}

}

希望能帮到你

一下这些是源码中的一些网络类型定义，可以参考一下

❸ Android WiFi开发，如何自动连接的代码

❹ Android之WIFI-网络可用性校验（NetworkMonitor）

流程框架

基础知识

源码

细节
1.WifiStateMachine在状态L2ConnectedState时，进行NetworkAgent初始化。
NetworkAgent初始化的过程建立与ConnectivityService通信

2.ConnectivityService的registerNetworkAgent创建NetworkAgentInfo

3.NetworkAgentInfo的初始化，创建NetworkMonitor，而NetworkMonitor则是监听网络的可用性

4.NetworkMonitor

adb控制

❺ 有关android内核的wifi驱动api

通过程序来实现wifi的自动连接。

这两天对android的wifi功能研究了一下。下面共享出自己封装的WifiConnect类。（这里参考了ZXing开源项目中wifi模块）

首先，要了解android关于wifi的API.

如果喜欢看English API，这是android关于wifi的API地址：

http://developer.android.com/reference/android/net/wifi/package-summary.html（配置Wifi，还需要设定权限，android中关于wifi的API文档中说明了要添加什么权限）

如果一看英语就头疼，这里有关于wifi的api的中文解释

http://note.sdo.com/u/1500295617/n/prb71~jGAHfpnM0l000bgN

切入正题,这里贴出一个封装了的类(WifiConnect)，在实例化WifiConnect对象时，需要传入一个WifiManager对象。WifiConnect类向外部提供一个Connect方法，参数是无线的SSID，password，还有加密类型。

[java] view plainprint?

❻ 在android上查看wifi状态，代码如下：

不知道你的程序报的是什么错，给你一个例子吧，不过方法和你的有点差别：
public class WifiAdmin {
/**WiFi Manager**/
private WifiManager wifimanager;
/**WiFi Information**/
private WifiInfo wifiinfo;
/**Activity NetWork List**/
private List<ScanResult> netlist;
/**Configured NetWork List**/
private List<WifiConfiguration> connectedlist;
/**WiFi Lock**/
private WifiLock wifilock;

public WifiAdmin(Context context) {
wifimanager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
}

/**
* WiFi Operate
* */
/**Open WiFi**/
public void openWifi() {
if (!wifimanager.isWifiEnabled()) {
wifimanager.setWifiEnabled(true);
}
}
/**Close WiFi**/
public void closeWifi() {
if (wifimanager.isWifiEnabled()) {
wifimanager.setWifiEnabled(false);
}
}
/**WiFi State**/
public int checkState() {
return wifimanager.getWifiState();
}

/**
* WiFiLock Operate
* */
/**Create WiFiLock**/
public void creatWifiLock() {
wifilock = wifimanager.createWifiLock("Test");
}
/**Lock WiFi**/
public void acquireWifiLock() {
wifilock.acquire();
}
/**Clear WiFiLock**/
public void releaseWifiLock() {
if (wifilock.isHeld()) {
wifilock.release();
}
}
/**
* WiFiInfo Operate
* */
/**Get WiFiInfo**/
public WifiInfo getWifiInfo(){
wifiinfo = wifimanager.getConnectionInfo();
return wifiinfo;
}

/**
* NetWork Operate
* */
/**Scan**/
public void startScan() {
wifimanager.startScan();
netlist = wifimanager.getScanResults();
connectedlist = wifimanager.getConfiguredNetworks();
}
/**Get Configured NetWork**/
public List<WifiConfiguration> getConfiguration() {
return connectedlist;
}
/**Get Activity NetWork**/
public List<ScanResult> getWifiList() {
return netlist;
}
/**Connect a NetWork**/
public void connectConfiguration(int index) {
if (index < 0 || index > connectedlist.size()) {
return;
}
wifimanager.enableNetwork(connectedlist.get(index).networkId,true);
}
/**Add a NetWork**/
public void addNetwork(WifiConfiguration wcg) {
int wcgID = wifimanager.addNetwork(wcg);
wifimanager.enableNetwork(wcgID, true);
}
/**DisConnect a NetWork**/
public void disconnectWifi(int netId) {
wifimanager.disableNetwork(netId);
wifimanager.disconnect();
}
}
