架构

分层架构设计

HarmonyOS的分层架构主要包括三个层次:产品定制层、基础特性层和公共能力层。

本应用在产品定制层满足了不同设备类型的个性化需求。基础特性层提供了登录、我的、学习和发现等核心功能模块,为各设备提供通用的功能支持。公共能力层则提供了一套基础的开发组件和服务,包括公共UI组件、数据存储、网络和工具库,为应用开发提供了基础设施支持, 详见最佳实践-分层架构设计

模块化设计

在HarmonyOS中,模块化不仅是一个设计原则,更是一种开发实践。它旨在将应用程序拆分为多个功能模块,每个功能模块负责特定的功能或特性。功能模块可以独立开发、编译和部署,也可以在不同的设备上灵活组合和调用,实现真正的多端协同。

本应用展现了HarmonyOS模块化设计的优势和实践方法,详见最佳实践-模块化设计

一次开发多端部署

本应用使用自适应布局和栅格布局等响应式布局方式,实现一套代码同时适配手机、折叠屏、平板等多种设备的能力。

性能

  • 使用MVVM的设计模式,以实现更好的状态管理,减少应用的性能问题,详见状态管理最佳实践
  • 本应用中采用了属性动画、路径动画、粒子动画、lottie动画等方式实现了多种动画效果,详见动画实践案例
  • 本应用使用Navigation进行界面跳转,并使用了多种界面转场动画,详见合理使用界面间转场
  • 使用懒加载和组件复用等方式提升长列表加载性能,详见长列表加载性能优化
  • 本应用开发过程中,使用Frame分析、定位、解决卡顿问题,详见滑动卡顿分析

安全

为增强用户对于个人数据隐私保护的控制和知情权,本应用添加了用户隐私说明弹窗,首次启动获得用户同意后,应用才能开始正常使用,详见隐私保护最佳实践
