NotificationDemoActivity：

package com.amaker.notification;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

/**  
 * @Title: NotificationDemoActivity.java
 * @Package com.amaker.notification
 * @Description: 通知控制类
 * @author ZZL
 */
public class NotificationDemoActivity extends Activity {
	
	private Button clearBtn ;
	private NotificationManager manager ;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        init();
    }
    
    /**
     * 初始化方法实现
     */
    private void init(){
    	
    	//步骤一：取得系统服务
    	manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    	
    	//步骤二：
    	Notification notification = new Notification(R.drawable.notification,
    			"收到小马通知测试", System.currentTimeMillis());
    	
    	/**
    	 * 小马在这个地方写下为什么要在用到通知的时候要创建PendingIntent对象，是因为
    	 * Notification可以与应用程序脱离，即便应用程序关闭，Notification仍然
    	 * 会显示在状态栏中，当应用程序再次启动后，又可以重新控制这些Nofication消息,
    	 * 如清除或替换它们，因为才创建的此对象，更神奇的是这个对象由安卓系统本身维护哦，所以
    	 * 在应用关闭后这个对象是不会被翻译掉的
    	 */
    	//步骤三：
    	Intent intent = new Intent();
    	intent.putExtra("Msg", "这是从Notification传递过来的信息");
    	intent.setClass(this, NotificationDemoTest.class);
    	PendingIntent contentIntent = PendingIntent.getActivity(this, 0,intent, 0);
    	
    	//步骤四：setLatestEventInfo通过标准的方式将我们的通知设置到指定的View中
    	notification.setLatestEventInfo(this, "通知测试哦", "这是通知的主内容", contentIntent);
    	
    	//写下面这句话的时候大家注意下不要忘了加震动权限，不然没法调用硬件
    	//notification.defaults = Notification.DEFAULT_VIBRATE;
    	//下面这句是把当前的通知设置永久保存的Notification，好暴力呀，吼吼
    	//notification.flags = Notification.FLAG_NO_CLEAR
    	//下面这句是指：如果要让其它的软件检测到永久保存的通知时可以这样写
    	//Notification.flags = Nofication.FLAG_ONGOING_EVENT;
    	/**
    	 * 在这一步需要指定标识Notification的唯一ID，这个ID必须相对于同一个
    	 * NoficationManager对象是唯一的，否则就会覆盖相同ID的Notification
    	 */
    	//步骤五：
    	manager.notify(R.drawable.notification, notification);
    	
    	clearBtn = (Button)findViewById(R.id.button1);
    	clearBtn.setOnClickListener(new OnClickListener() {
    		
    		@Override
    		public void onClick(View v) {
    			manager.cancel(R.drawable.notification);
    			//清除所有通知：
    			//manager.cancelAll();
    		}
    	});
    	
    }
    
}
