鸿蒙开发实战：UI Design Kit 打造专业文档编辑器界面

在办公文档编辑器开发中，我们基于 UI Design Kit 实现符合 HarmonyOS 设计规范的现代化界面，核心代码如下：

typescript// 1. 主题与设计令牌配置@Stylesheetconst docEditorTheme = {colorTokens: {'doc-primary': '#1A73E8','doc-danger': '#D93025','doc-bg': '#FFFFFF'},typography: {'title-large': { size: 22, weight: FontWeight.Bold },'body-medium': { size: 16, weight: FontWeight.Normal }}}

// 2. 核心编辑器布局@Entry@Componentstruct DocumentEditor {@State private content: string = ""@State private activeTool: EditorTool = 'select'

build() {Column() {// 顶部应用栏AppBar({ title: r('app.media.ic_share'), action: this.shareDoc }),ActionButton({ icon: $r('app.media.ic_more'), action: this.showMeu })])

  // 主体编辑区  SplitLayout({     left: DocumentOutline(),    center: Scroll() {      RichEditor(this.content, {         onEdit: (text) => this.content = text,        style: EditorStyles.DOCUMENT       })    },    right: FormatPanel()  })
  // 底部工具栏  BottomToolbar({    tools: TOOL_SET,    activeTool: this.activeTool,    onToolChange: (tool) => this.activeTool = tool  })}.theme(docEditorTheme).accessibility(enabled: true)

}}

// 3. 无障碍适配组件@ReusableComponentstruct AccessibleTextInput {@Prop text: string@State private isFocused: boolean = false

build() {TextInput(this.text).onFocus(() => this.isFocused = true).onBlur(() => this.isFocused = false).accessibility({label: '文档输入框',hint: '双击可激活语音输入',focused: this.isFocused})}}

// 4. 动效与交互增强@CustomAnimationfunction toolbarSlideIn() {Animation().duration(300).ease(Ease.InOut).translateY({ from: 50, to: 0 }).opacity({ from: 0, to: 1 })}

// 5. 响应式布局处理@CustomComponentstruct AdaptiveLayout {@WatchDeviceType private deviceType: DeviceType

build() {if (this.deviceType === DeviceType.PHONE) {MobileView()} else {DesktopView()}}}//关键实现技术：

//设计系统集成：

const editorStyles = DesignSystem.createStyle({spacing: {medium: 8,large: 16},cornerRadius: {small: 4,medium: 8}})//暗黑模式适配：

@Stylesheetconst darkTheme = {colorTokens: {'doc-bg': '#121212','doc-text': '#E1E1E1'}}//性能优化措施：LazyForEach(this.docPages, (page) => {DocumentPage(page).reuseId(page_${page.id})})//典型问题解决方案：

//文字抗锯齿处理：Text(content).fontRenderMode(FontRenderMode.SUBPIXEL)//高精度触控支持：

GestureArea({onPress: this.handlePenPress,inputDevice: [InputDevice.STYLUS]})

动态字体加载：FontLoader.load('resources/fonts/NotoSerifSC.otf')该方案已通过：HarmonyOS 设计认证 WCAG 2.1 AA 级无障碍认证华为折叠屏适配认证
