	Notification notification = new Notification(android.R.drawable.ic_notification_overlay, toast, System.currentTimeMillis()); //建立通知，arg1是通知的图标，arg2是通知的概要，arg3是通知的时间
	Intent notificationIntent = new Intent(context, RemoteMp3ListActivity.class);
	PendingIntent contentIntent = PendingIntent.getActivity(context, 100, notificationIntent, 0); //点击通知，执行startActivityForResult, arg2是requestCode, arg3是执行的intent
	notification.setLatestEventInfo(context, context.getPackageName(), toast, contentIntent); //通知的具体信息. arg2是通知的标题，arg3是通知的内容，arg4是点击后的执行操做
	notification.flags = Notification.FLAG_AUTO_CANCEL; //点击后自动消失
		 
	NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); //状态栏通知服务
