这两天，无意中看到飞鸽传书的wifi热点创建与搜索模块，于是乎很蛋疼的还原了一下他的这一小模块代码，感觉效果差不多，跟大家分享一下：
源码下载地址:http://download.csdn.net/download/weidi1989/5293352
我们先来看看效果图：
1.山寨机主界面
2.进应用就会自动搜索wifi，这个动画效果截屏变形了。将就一下吧
3.搜索结果显示
4.连接上我另外一台山寨机创建的热点
5.正在创建热点
6.热点创建成功，关于那个黑黑的gif动画，我试了三种方法：①.网上导了那个很泛滥的包，不行，②.用Movie实现的动画，还是不行，在有的机器上会花屏，③.就是下面这个效果了，自定义的一个view，由于图片是透明的，所以黑色底没有解决。
下面是几个关键类的代码：
1.我们先来看看这个广播：WTBroadcast，通过这个广播，可以及时更新我们的界面显示信息。重点是“android.net.wifi.WIFI_STATE_CHANGED” 与“android.net.wifi.STATE_CHANGE”两个状态的区别
/**
* wifi状态监听广播
*
* @author way
*
*/
public class WTBroadcast extends BroadcastReceiver {
public static ArrayList<EventHandler> ehList = new ArrayList();
public void onReceive(Context paramContext, Intent paramIntent) {
if (paramIntent.getAction().equals("android.net.wifi.SCAN_RESULTS")) {
// 搜索到wifi热点结果广播
Log.i("WTScanResults", "android.net.wifi.SCAN_RESULTS");
// 遍历通知各个监听接口
for (int j = 0; j < ehList.size(); j++)
((EventHandler) ehList.get(j)).scanResultsAvailable();
} else if (paramIntent.getAction().equals(
"android.net.wifi.WIFI_STATE_CHANGED")) {
// wifi打开或关闭广播(不需要连接上一个SSID)
Log.e("WTScanResults", "android.net.wifi.WIFI_STATE_CHANGED");
for (int j = 0; j < ehList.size(); j++)
((EventHandler) ehList.get(j)).wifiStatusNotification();
} else if (paramIntent.getAction().equals(
"android.net.wifi.STATE_CHANGE")) {
// 连接上一个SSID后发出的广播，与android.net.wifi.WIFI_STATE_CHANGED有一定区别
Log.e("WTScanResults", "android.net.wifi.STATE_CHANGE");
for (int i = 0; i < ehList.size(); i++)
((EventHandler) ehList.get(i)).handleConnectChange();
}
}
/**
* 用来更新的接口
*
* @author way
*
*/
public static abstract interface EventHandler {
public abstract void handleConnectChange();
public abstract void scanResultsAvailable();
public abstract void wifiStatusNotification();
}
}2.接下来是主Activity了：WTActivity，在这个Activity中，我们来处理各种界面事件，同时根据wifi状态变化，动态更新界面，值得学习的是自定义view和handler事件处理，还有超时线程的理论。内容比较多，我把它综合到一个类中，其实可以把一些常用的函数放在Application类中。
