鸿蒙智能家居【1.0】
2022-07-07 16:59:00 【InfoQ】
应用场景:
- 智能家居。
搭建OpenHarmony环境
- 获取OpenHarmony系统版本:标准系统解决方案(二进制)
- 以3.0版本为例:
- 搭建烧录环境
- 完成DevEco Device Tool的安装
- 完成Dayu200开发板的烧录
- 搭建开发环境
- 开始前请参考工具准备,完成DevEco Studio的安装和开发环境配置。
- 开发环境配置完成后,请参考使用工程向导创建工程(模板选择“Empty Ability”),选择eTS语言开发。
- 工程创建完成后,选择使用真机进行调测。

创建好的 eTS工程目录
- index.ets:用于描述UI布局、样式、事件交互和页面逻辑。
- app.ets:用于全局应用逻辑和应用生命周期管理。
- pages:用于存放所有组件页面。
- resources:用于存放资源配置文件。
