引言
一、鸿蒙系统概述
1.1 简介
1.2 鸿蒙开发的优势
二、鸿蒙开发环境搭建
2.1 安装鸿蒙DevEco Studio
2.2 创建鸿蒙应用项目
三、鸿蒙应用开发基础
3.1 开发语言与框架
3.2 项目结构
3.3 ArkTS 声明式 UI
// 引入组件
import { Text, Button } from '@ohos.ui.components';
@Entry
@Component
struct HelloWorld {
private message: string = 'Hello, HarmonyOS!';
build() {
Column() {
Text(this.message)
.fontSize(50)
.fontWeight(FontWeight.Bold)
.margin({ top: 20 })
Button('Click me')
.onClick(() => {
this.message = 'Hello, World!';
this.$update(); // 更新UI
})
.margin({ top: 10 })
}
}
}3.4 页面路由与导航
// 在某个组件的某个方法中
navigateToNewPage() {
router.push({
uri: 'pages/NewPage/NewPage',
params: {
key: 'value'
}
});
}3.5 应用配置与权限
{
"app": {
"bundleName": "com.example.myapp",
"vendor": "com.example",
"version": {
"code": 1,
"name": "1.0"
},
"permissions": [
{
"name": "ohos.permission.INTERNET"
}
]
},
"deviceConfig": {
"default": {}
},
"module": {
"package": "com.example.myapp",

"tablet"
],
"distro": {
"deliveryWithInstall": true,
"moduleName": "entry",
"moduleType": "entry"
},
"abilities": [
{
"name": "MainAbility",
"srcPath": "entry/src/main/ets/MainAbility/MainAbility.ts",
"visible": true,
"description": "$string:mainability_description",
"icon": "$media:icon",
"label": "$string:entry_MainAbility",

五、实战案例：开发一个简单的鸿蒙应用
5.1 创建项目
5.2 设计页面布局
// IndexPage.ets
@Entry
@Component
struct IndexPage {
private message: string = 'Hello, HarmonyOS!';
build() {
Column() {
Text(this.message)
.fontSize(24)
.fontWeight(FontWeight.Bold)
.textAlign(TextAlign.Center)
.margin({ top: 50 })
Button('Change Message')
.onClick(() => {
this.message = 'Hello, World from HarmonyOS!';
this.$update();
})
.margin({ top: 20 })
}
.justifyContent(FlexAlign.Center)
.alignItems(ItemAlign.Center)
}
}5.3 配置应用入口
