【Android】利用服務Service創建標題欄通知

創建標題欄通知的核心代碼

	public void CreateInform() {
		//定義一個PendingIntent，當用戶點擊通知時，跳轉到某個Activity(也可以發送廣播等)
		Intent intent = new Intent(context,MainActivity.class);
		PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
		
		//創建一個通知
		Notification notification = new Notification(R.drawable.icon, "巴拉巴拉~~", System.currentTimeMillis());
		notification.setLatestEventInfo(context, "點擊查看", "點擊查看詳細內容", pendingIntent);
		
		//用NotificationManager的notify方法通知用戶生成標題欄消息通知
		NotificationManager nManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
		nManager.notify(100, notification);//id是應用中通知的唯一標識
		//如果擁有相同id的通知已經被提交而且沒有被移除，該方法會用更新的信息來替換之前的通知。
	}
