通知
通知用于在应用程序处于后台时向用户提示必要的信息。如微信好友消息、追剧更新、支付宝付款等。
1 文本通知
在应用中发布通知，手机顶栏出现图标，下拉顶栏显示通知框。
NotificationNormalContent normal = new NotificationNormalContent() .setTitle("祝您健康") // 标题 .setText("休息，休息一会……") // 内容 .setAdditionalText("不会休息就不会工作"); // 次要内容 NotificationContent content = new NotificationContent(normal); NotificationRequest request = new NotificationRequest(1001) // 通知ID .setContent(content); // ID相同的通知，新的替换旧的 try { NotificationHelper.publishNotification(request); } catch (RemoteException exception) { HiLog.error(label, exception.getLocalizedMessage()); }
