线程池管理的基类Activity

看以前同事写了个基类 感觉每次  获取网络数据和异步操作都new 一条线程,感觉对性能以及APP 的 内存 感觉有很大的占用,所以今天写了一个用线程池管理的基类 希望对大家有所帮助下面上code

package com.sqbc.tong.impl;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

import com.sqbc.tong.activity.IActivity;

import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.support.v4.app.FragmentActivity;
import android.view.Window;

/**
 * 此基类用于线程池管理管理线程需要添加什么dialog啦 什么东西的自行添加
 * 
 * @author 张红亮
 * 
 */

public class ExecutorServiceBaseActivity extends FragmentActivity implements
		IActivity {

	private ExecutorService executorService = null;

	@Override
	protected void onCreate(Bundle arg0) {
		// TODO Auto-generated method stub
		this.requestWindowFeature(Window.FEATURE_NO_TITLE);

		executorService = Executors.newFixedThreadPool(2);// 最大线程数自行设置控制线程条数
		init();
	}

	public void init() {

	}

	@Override
	public void runLoadThread(int messageId) {
		// TODO Auto-generated method stub
		executorService.submit(new MyThread(messageId));

	}

	@Override
	public void refresh(int messageId, Object params) {
		// TODO Auto-generated method stub

	}

	/**
	 * The handler for refresh UI.
	 */
	protected Handler mHandler = new Handler() {
		@Override
		public void handleMessage(Message msg) {

			refresh(msg.what, msg.obj);
		}
	};

	/**
	 *  runnable
	 * @author Administrator
	 *
	 */
	
	class MyThread implements Runnable {

		private int mMessageId = 0;

		MyThread(int messageId) {
			this.mMessageId = messageId;
		}

		@Override
		public void run() {
			Message msg = Message.obtain();
			msg.what = mMessageId;

			// Load data for the activity.
			msg.obj = loadData(mMessageId);
			mHandler.sendMessage(msg);
		}
	}
	/**
	 * 线程内部访问的方法
	 * @param messageId
	 * @return
	 */

	public Object loadData(int messageId) {

		return null;
	}

	/**
	 * finish activity
	 */
	public void back() {

		this.finish();
	}

}

下面是定义的接口

package com.sqbc.tong.activity;

public interface IActivity {
	/**
	 * Start to run the thread that is to load data for UI.
	 */
	public void runLoadThread(int messageId);

	/**
	 * Refresh UI.
	 * 
	 * @param params
	 */
	public void refresh(int messageId, Object params);
	
	 
	 
}

希望对大家有所帮助!
