android 2.3 notifaction 使用-优快云博客

本文介绍如何在Android应用中创建并显示通知。通过使用NotificationManager及Intent等组件，文章详细展示了设置通知图标、声音、取消方式及时戳的具体实现过程，并提供了Intent与PendingIntent的使用示例。

	NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
		
		// Notification
		Notification notification = new Notification();
		notification.icon = R.drawable.ic_launcher; // 设置通知的图标
		notification.defaults |= Notification.DEFAULT_SOUND;
//		notification.defaults |= Notification.DEFAULT_VIBRATE;
		notification.flags |= Notification.FLAG_AUTO_CANCEL;
		notification.when = System.currentTimeMillis();
		
		 Intent intent = new Intent(context,
		 MainActivity.class);
//		 intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//		 intent.setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
//		 intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
//		 intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
//		 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
		//
		 PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
		 intent, PendingIntent.FLAG_UPDATE_CURRENT);
		//
		 notification.setLatestEventInfo(context, "有新消息", message.getContent(),
		 contentIntent);
		 
		 notificationManager.notify(message.getTime().hashCode(), notification);
