实现在Android简单封装类似JQuery异步请求

在android开发中经常会使用异步请求数据，通常会使用handler或者AsyncTask去做，handler 配合message 使用起来比较麻烦，AsyncTask 线程池只允许128个线程工作，会有溢出的问题，（当然一般情况不会有那么多线程同时工作的）所以写了这个代码，还望高手指正！

package com.xbl.task;import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.net.URL;import java.util.concurrent.Executor;import java.util.concurrent.ExecutorService;import java.util.concurrent.Executors<P>import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.util.Logpublic class JQuery {  private static final String KEY = "key"; private static String TAG = "JQuery"; private static final int N = 5;// 5个工人  private static final Executor worker = Executors.newFixedThreadPool(N);// 线程池 private static final Handler handler = new Handler(){  @Override  public void handleMessage(Message msg) {   TaskListener listener = (TaskListener)msg.obj;   Object result = msg.getData();   if(listener !=null ){    listener.callBack(result);   }   destory();  } };  private JQuery(){   }  public static void execute(final String url,final TaskListener listener){  worker.execute(new Runnable() {   @Override   public void run() {    String result = null;    try {     result = WebUtil.get(url);    } catch (Exception e) {     Log.e(TAG, e.getMessage());    }        Message msg = new Message();    Bundle data = new Bundle();    data.putSerializable(KEY, result);    msg.setData(data);    msg.obj = listener;    handler.sendMessage(msg);   }  }); }  //销毁线程 private static void destory() {  if (worker != null && worker instanceof ExecutorService) {   ExecutorService es = (ExecutorService) worker;   if (!es.isShutdown()) {    es.shutdown();   }  } }   public interface TaskListener{  public void callBack(Object result); } /**  *   * 不必太在意此处代码，只是示例  *  */ public static class WebUtil{    public static String get(String url) throws Exception{   InputStream inputStream = new URL(url).openStream();   StringBuilder strBuilder = new StringBuilder();   BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));   for (String s = reader.readLine(); s != null; s = reader.readLine())     strBuilder.append(s);      inputStream.close();   return strBuilder.toString();  }  }}

[Java]代码

//调用方法：JQuery.execute("http://weather.news.qq.com/inc/minisite_125.js", new JQuery.TaskListener() { @Overridepublic void callBack(Object result) {TextView t = new TextView(TaskDemoActivity.this);t.setText(String.valueOf(result));LinearLayout layout = (LinearLayout)findViewById(R.id.layout1);layout.addView(t);}});
