HarmonyOS提供了通知功能,即在一个应用的UI界面之外显示的消息,主要用来提醒用户有来自该应用中的信息。当应用向系统发出通知时,它将先以图标的形式显示在通知栏中,用户可以下拉通知栏查看通知的详细信息。
效果如下:
代码如下:
- private void NotificationSlot(){
- NotificationSlot slot = new NotificationSlot("slot_001", "slot_default", NotificationSlot.LEVEL_MIN); // 创建notificationSlot对象
- slot.setDescription("NotificationSlotDescription");
- slot.setEnableVibration(true); // 设置振动提醒
- slot.setEnableLight(true); // 设置开启呼吸灯提醒
- slot.setLedLightColor(Color.RED.getValue());// 设置呼吸灯的提醒颜色
- try {
- NotificationHelper.addNotificationSlot(slot);
- } catch (RemoteException ex) {
- HiLog.error((HiLogLabel) LABEL, "Exception occurred during addNotificationSlot invocation.");
- }
- int notificationId = 1;
- NotificationRequest request = new NotificationRequest(notificationId);
- request.setSlotId(slot.getId());
- String title = "消息";
- String text = "哈哈哈哈哈哈哈哈";
- NotificationRequest.NotificationNormalContent content = new NotificationRequest.NotificationNormalContent();
- content.setTitle(title)
- .setText(text);
- NotificationRequest.NotificationContent notificationContent = new NotificationRequest.NotificationContent(content);
- request.setContent(notificationContent); // 设置通知的内容
- try {
- NotificationHelper.publishNotification(request);
- } catch (RemoteException ex) {
- HiLog.error((HiLogLabel) LABEL, "Exception occurred during publishNotification invocation.");
- }
- }
