notification.setLatestEventInfo(context, title, message, pendingIntent);     不建议使用




低于API Level 11版本,也就是Android 2.3.3以下的系统中,setLatestEventInfo()函数是唯一的实现方法。 

Intent  intent = new Intent(this,MainActivity);  
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);  
notification.setLatestEventInfo(context, title, message, pendingIntent);          
manager.notify(id, notification);  

    高于API Level 11,低于API Level 16 (Android 4.1.2)版本的系统中,可使用Notification.Builder来构造函数。但要使用getNotification()来使notification实现。前面版本在notification中设置的Flags,icon等属性都已经无效,要在builder里面设置。
Notification.Builder builder = new Notification.Builder(context)  
            .setAutoCancel(true)  
            .setContentTitle("title")  
            .setContentText("describe")  
            .setContentIntent(pendingIntent)  
            .setSmallIcon(R.drawable.ic_launcher)  
            .setWhen(System.currentTimeMillis())  
            .setOngoing(true);  
notification=builder.getNotification();  

    高于API Level 16的版本,就可以用Builder和build()函数来配套的方便使用notification了。
Notification notification = new Notification.Builder(context)    
         .setAutoCancel(true)    
         .setContentTitle("title")    
         .setContentText("describe")    
         .setContentIntent(pendingIntent)    
         .setSmallIcon(R.drawable.ic_launcher)    
         .setWhen(System.currentTimeMillis())    
         .build();

		m_Button1 = (Button) this.findViewById(R.id.button1);

		// 点击通知时转移内容

		mIntent = new Intent(MainActivity.this, MainActivity1.class);

		mPendingIntent = PendingIntent.getActivity(MainActivity.this, 0,
				mIntent, 0);

		notification = new Notification.Builder(context).setAutoCancel(true)
				.setContentTitle("qq正在运行").setContentText("qq,让交流更多方便")
				.setContentIntent(mPendingIntent)
				.setSmallIcon(R.drawable.ic_launcher)
				.setWhen(System.currentTimeMillis()).build();

		m_Button1.setOnClickListener(new Button.OnClickListener() {
