搞了好几天终于有点眉目了，这里接着总结一下Android中WiFi的使用，在前面（http://smallwoniu.blog.51cto.com/3911954/1334951）我们已经简单了解了Wifi实际操作中所用到的几个主要类，今天就剖析一个WIFI搜索、创建、关闭、连接及一些简单的动画的综合案例。
首先，我们还是看一下我们项目的框架
MainActivity类：（处理wifi消息，加载UI）
/** * 主界面 * @author ZHF * */public class MainActivity extends Activity implements EventHandler{ //消息事件 public static final int m_nWifiSearchTimeOut = 0;// 搜索超时 public static final int m_nWTScanResult = 1;// 搜索到wifi返回结果 public static final int m_nWTConnectResult = 2;// 连接上wifi热点 public static final int m_nCreateAPResult = 3;// 创建热点结果 public static final int m_nUserResult = 4;// 用户上线人数更新命令(待定) public static final int m_nWTConnected = 5;// 点击连接后断开wifi，3.5秒后刷新adapter //一些常量 public static final String PACKAGE_NAME = "com.zhf.wifidemo.wifi"; //应用包名 public static final String FIRST_OPEN_KEY = "version"; //版本号信息 public static final String WIFI_AP_HEADER = "zhf_"; public static final String WIFI_AP_PASSWORD ="zhf12345"; //wifi操作事件（枚举）-->方便弹出对话框处理事件 private int wFOperateEnum = WFOperateEnum.NOTHING; //三个重要的类 public WFSearchProcess m_wtSearchProcess; //WiFi搜索进度条线程 public WifiAdmin m_wiFiAdmin; //Wifi管理类 public CreateAPProcess m_createAPProcess; //创建Wifi热点线程 //相关控件 private WFSearchAnimationFrameLayout m_FrameLWTSearchAnimation;

1.首先，初始化主界面（xml有些复杂，慢慢理一下就好了，不是什么大问题）接下来，处理三个重要的按钮事件：右上角的搜索wifi按钮、中间创建或关闭热点按钮、对话框中确定按钮。处理前两者事件时，需关注当前wifi状态，若为占用，需弹出提醒对话框来根据当前WiFi操作（WFOperateEnum类中定义好了）事件，来创建、关闭、搜索等具体事务。
2.之所以定义广播接收者，是为了监听当wifi状态发生变化时，能够及时更新界面
广播接收者WIFIBroadcast类:
package com.zhf.wifidemo.broadcast;import java.util.ArrayList;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.net.wifi.WifiManager;import android.util.Log;/** * 监听wifi热点变化 * @author ZHF * */public class WIFIBroadcast extends BroadcastReceiver{ public static ArrayList ehList = new ArrayList(); @Override public void onReceive(Context context, Intent intent) { //搜索到wifi热点结果的广播: "android.net.wifi.SCAN_RESULTS" if(intent.getAction().endsWith(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) { Log.i("WTScanResults---->扫描到了可用网络---->", "android.net.wifi.SCAN_RESULTS"); //遍历通知各个监听接口 for(int i = 0; i < ehList.size(); i++) { ((EventHandler)ehList.get(i)).scanResultsAvaiable(); } //wifi打开或关闭状态变化 "android.net.wifi.WIFI_STATE_CHANGED" }else if(intent.getAction().endsWith(WifiManager.WIFI_STATE_CHANGED_ACTION)) { Log.i("WTScanResults----->wifi状态变化--->", "android.net.wifi.WIFI_STATE_CHANGED"); //这里不需要连接一个SSID（wifi名称） for(int j = 0; j < ehList.size(); j++) { ((EventHandler)ehList.get(j)).wifiStatusNotification(); } //连接上一个SSID后发出的广播，(注：与android.net.wifi.WIFI_STATE_CHANGED的区别) }else if(intent.getAction().endsWith(WifiManager.NETWORK_STATE_CHANGED_ACTION)) { Log.i("WTScanResults----->网络状态变化---->", "android.net.wifi.STATE_CHANGE"); for(int m = 0; m < ehList.size(); m++) { ((EventHandler)ehList.get(m)).handleConnectChange(); } } } /** * 事件监听接口 * @author ZHF * */ public static abstract interface EventHandler { /**处理连接变化事件**/ public abstract void handleConnectChange(); /**扫描结果是有效事件**/ public abstract void scanResultsAvaiable(); /**wifi状态变化事件**/ public abstract void wifiStatusNotification(); } } 说明：监听系统wifi状态变化，内部定义了一个事件处理接口，当wifi状态发生变化时，让其实现类去发送消息更新界面。
CreateAPProcess类：
package com.zhf.wifidemo.ui;import android.net.wifi.WifiManager;import android.os.Message;import com.zhf.wifidemo.wifi.MainActivity;/** * 创建Wifi热点 * @author ZHF * */public class CreateAPProcess implements Runnable{ public MainActivity context; public boolean running = false; private long startTime = 0L; private Thread thread = null; public CreateAPProcess(MainActivity context) { super(); this.context = context; } @Override public void run() { while(true) { if(!running) return; //WIFI_STATE_ENABLED 3 //WIFI_AP_STATE_ENABLED 13 if((context.m_wiFiAdmin.getWifiApState() == WifiManager.WIFI_STATE_ENABLED) || (context.m_wiFiAdmin.getWifiApState() == 13) || (System.currentTimeMillis() - this.startTime >= 30000L)){ //wifi可用 或 热点可用 Message msg = context.mHandler.obtainMessage(context.m_nCreateAPResult); context.mHandler.sendMessage(msg); } try { Thread.sleep(5L); } catch (Exception e) { e.printStackTrace(); } } } public void start() { try { thread = new Thread(this); running = true; startTime = System.currentTimeMillis(); thread.start(); //开启线程 } catch (Exception e) { e.printStackTrace(); } } public void stop() { try { running = false; thread = null; startTime = 0L; } catch (Exception e) { // TODO: handle exception } }} 其他类文件具体看源码，当创建一个热点成功后，等待其他客户端搜索
上图：
WIFIAdapte类：
/** * 网络列表适配器 * @author ZHF * */public class WTAdapter extends BaseAdapter { private LayoutInflater mInflater; private List mList; //扫描到的网络结果列表 private MainActivity mContext; public WTAdapter(MainActivity context, List list) { // TODO Auto-generated constructor stub this.mContext = context; this.mList = list; this.mInflater = LayoutInflater.from(context); } //新加的一个函数，用来更新数据 public void setData(List list) { this.mList = list; notifyDataSetChanged(); } @Override public int getCount() { return mList.size(); } @Override public Object getItem(int position) { return mList.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { //获取点击向的扫描结果 final ScanResult localScanResult = mList.get(position); //获取wifi类// final WifiAdmin wifiAdmin = WifiAdmin.getInstance(mContext); final WifiAdmin wifiAdmin = mContext.m_wiFiAdmin; final ViewHolder viewHolder; if (convertView == null) { viewHolder = new ViewHolder(); convertView = mInflater.inflate(R.layout.wtitem, null); //加载布局模板控件 viewHolder.textVName = ((TextView) convertView.findViewById(R.id.name_text_wtitem)); viewHolder.textConnect = ((TextView) convertView.findViewById(R.id.connect_text_wtitem)); viewHolder.linearLConnectOk = ((LinearLayout) convertView.findViewById(R.id.connect_ok_layout_wtitem)); viewHolder.progressBConnecting = ((ProgressBar) convertView.findViewById(R.id.connecting_progressBar_wtitem)); convertView.setTag(viewHolder); } else { viewHolder = (ViewHolder) convertView.getTag(); } //点击连接处理事件 viewHolder.textConnect.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { //创建wifi网络 WifiConfiguration localWifiConfiguration = wifiAdmin.createWifiInfo(localScanResult.SSID, MainActivity.WIFI_AP_PASSWORD, 3,"wt"); //添加到网络 wifiAdmin.addNetwork(localWifiConfiguration); //"点击链接"消失，显示进度条， viewHolder.textConnect.setVisibility(View.GONE); viewHolder.progressBConnecting.setVisibility(View.VISIBLE); viewHolder.linearLConnectOk.setVisibility(View.GONE); //点击后3.5s发送消息 mContext.mHandler.sendEmptyMessageDelayed(mContext.m_nWTConnected, 3500L); } }); // 点击断开处理事件 viewHolder.linearLConnectOk.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { //断开指定wifi热点 wifiAdmin.disconnectWifi(wifiAdmin.getWifiInfo().getNetworkId()); //"断开连接"消失，进度条显示 viewHolder.textConnect.setVisibility(View.GONE); viewHolder.progressBConnecting.setVisibility(View.VISIBLE); viewHolder.linearLConnectOk.setVisibility(View.GONE); //点击后3.5s发送消息 mContext.mHandler.sendEmptyMessageDelayed(mContext.m_nWTConnected, 3500L); } }); //初始化布局 viewHolder.textConnect.setVisibility(View.GONE); viewHolder.progressBConnecting.setVisibility(View.GONE); viewHolder.linearLConnectOk.setVisibility(View.GONE); viewHolder.textVName.setText(localScanResult.SSID); //显示热点名称 // 正连接的wifi信息 WifiInfo localWifiInfo = wifiAdmin.getWifiInfo(); if (localWifiInfo != null) { try {//正在连接 if ((localWifiInfo.getSSID() != null)&& (localWifiInfo.getSSID().equals(localScanResult.SSID))) { viewHolder.linearLConnectOk.setVisibility(View.VISIBLE); return convertView; } } catch (NullPointerException e) { e.printStackTrace(); return convertView; } viewHolder.textConnect.setVisibility(View.VISIBLE); } return convertView; } public final class ViewHolder { public LinearLayout linearLConnectOk; public ProgressBar progressBConnecting; public TextView textConnect; public TextView textVName; }} 点击连接，实现客户连接，此时他们将处于同一网段内，接下来就可以自己实现传输数据，操控等一系列操作了。 在下一篇中我会继实现一个基于wif热点的多人聊天室，希望能帮助到大家！
