OpenHarmony开发案例：【自定义通知】-编程知识

介绍

本示例使用[@ohos.notificationManager] 等接口，展示了如何初始化不同类型通知的通知内容以及通知的发布、取消及桌面角标的设置，通知类型包括基本类型、长文本类型、多行文本类型、图片类型、带按钮的通知、点击可跳转到应用的通知。

效果预览：

使用说明

1.启动应用后，弹出是否允许发送通知的弹窗，点击允许后开始操作；

2.点击界面中对应的按钮发布不同类型的通知，下拉状态栏，在通知栏可以看到发布的通知；

3.打开提示音和震动效果开关后，再点击对应按钮发布不同类型的通知，在通知的同时会伴有提示音或震动效果；

4.点击消息列表Tab页，可以查看到刚才发送的消息，消息右边会显示数量，点击相应的消息可进行消息读取，取消相应通知；

5.回到仿桌面，可以看到角标数量，对应消息数量（使用前需安装并启动[仿桌面应用]）；

6.点击取消所有通知，可以取消本应用发布的所有通知；

允许发送通知、发送通知、取消通知的功能接口封装在NotificationUtil，源码参考：[NotificationUtil.ets]

允许发送通知：在进入[Index.ets]前通过notificationUtil.enableNotification()调用notification.requestEnableNotification()接口向用户请求发送通知；
发送通知：通过publishNotification()封装发布通知的接口；
取消通知：在[Index.ets]页面中通过点击事件调用cancelAllNotifications()取消所有的通知或者通过cancelNotificationById()取消指定id的通知；
获取应用所有消息通知、取消相关类型通知，角标管理接口封装在NotificationManagementUtil，源码参考：[NotificationManagementUtil.ets]

获取应用所有消息通知：在constructor() 构造函数中调用@ohos.notificationManager中的getActiveNotifications接口获取所有通知及相应类型通知数量，通过封装getAllNotifications() 对外提供接口获取当前消息及消息数量。
取消相关类型通知：通过cancelNotificationType()封装取消相关通知类型的接口；
角标管理接口：通过setBadgeNumber()封装设置应用角标数量的接口，通过getBadgeNumber()封装获取当前应用角标数量的接口。
添加一条通知：通过addNotification()封装接口添加一条通知到消息管理器，当发送通知的时候进行调用。
NotificationOperations向外提供接口，在页面中调用它们来实现功能，源码参考：[NotificationOperations.ets]

发布通知：在[Index.ets] 页面中通过点击事件调用NotificationOperations中封装的对应的方法，然后从NotificationContentUtil中获取对应的主体内容content，将content传递给NotificationRequestUtil得到完整的发布信息，最后调用NotificationUtil.publishNotification()发布内容；
播放提示音、马达震动的功能在NotificationUtil调用发布通知的接口处进行判断是否开启，源码参考：[NotificationOperations.ets]

发布通知：在[Index.ets]通过publishNotification()封装发布通知的接口的同时，根据NotificationUtil类中对应变量的值判断是否开启了提示音或马达，若已开启，则执行对应代码段；
控制提示音或马达的开关：在[Index.ets]通过调用NotificationUtil类两个方法对NotificationUtil类中对应变量进行更改，开启为true，关闭为false；
自动化测试，对应用接口或系统接口进行单元测试，并且对基于UI操作进行UI自动化测试
模拟点击：在Index.test.ets的beforeAll中调用startAbility()拉起应用并进入首页，然后通过Driver的assertComponentExist、findComponent和findWindow等获取到对应组件的位置，最后通过click()模拟出人工点击对应组件的效果；
模拟各种操作流程：在Index.test.ets 的每个it里面，按一定逻辑顺序排好点击组件的顺序，从而模拟出人为操作的过程，最终，所有的it组成了整一个应用的自动化测试。

最后呢，很多开发朋友不知道需要学习那些鸿蒙技术？鸿蒙开发岗位需要掌握那些核心技术点？为此鸿蒙的开发学习必须要系统性的进行。

而网上有关鸿蒙的开发资料非常的少，假如你想学好鸿蒙的应用开发与系统底层开发。你可以参考这份资料，少走很多弯路，节省没必要的麻烦。由两位前阿里高级研发工程师联合打造的《鸿蒙NEXT星河版OpenHarmony开发文档》里面内容包含了（ArkTS、ArkUI开发组件、Stage模型、多端部署、分布式应用开发、音频、视频、WebGL、OpenHarmony多媒体技术、Napi组件、OpenHarmony内核、Harmony南向开发、鸿蒙项目实战等等）鸿蒙（Harmony NEXT）技术知识点
