问题现象
使用Tabs组件，如何实现当前显示页签为1的页面内容，点击某个页签使用router跳转到其他页面再返回时，显示的依然是页签为1的页面内容？

背景知识
onPageShow：页面每次显示时触发一次，包括路由过程、应用进入前台等场景，仅@Entry装饰的自定义组件作为页面时生效。
Tabs：通过页签进行内容视图切换的容器组件，每个页签对应一个内容视图。
getRouter().pushUrl()：跳转到应用内的指定页面，通过Promise获取跳转异常的返回结果。
解决方案
@Entry修饰的页面在显示时会触发onPageShow生命周期回调，可以在此回调中设置页面显示的初始状态，Tabs组件显示具体哪个页面由Tabs内的currentIndex参数决定的，当页面返回时在onPageShow()方法内重设currentIndex的值使其显示对应页面。运行下述示例需要自行创建一个简单的PageA页面。

class TabBar {
title: string;
index: number;

constructor(title: string, index: number) {
this.title = title;
this.index = index;
}
}

@Entry
@Component
struct TabsTestPage {
uiContext = this.getUIContext();
// 当前选中Tabs的索引
@State currentIndex: number = 1;
// 判断Tabs是否选中（用于自定义Tabs列表的选中状态）

@State selectedIndex: number = 0;
private tabsController: TabsController = new TabsController();
private tabBars: TabBar[] = [
new TabBar('翻译机', 0),
new TabBar('首页', 1),
new TabBar('推荐', 2),
];

// 页面显示时初始化状态
onPageShow(): void {
this.currentIndex = 1;
}

// 自定义Tabs组件构建函数
@Builder
TabBuilder() {
List() {
ForEach(this.tabBars, (item: TabBar, index: number) => {
ListItem() {
Column() {
Text(item.title) // 根据选中状态改变文字颜色
.fontColor(this.currentIndex === item.index ? '#0A59F7' : Color.Black)
.fontSize(20)
.align(Alignment.Center);
}
.justifyContent(FlexAlign.Center)
.alignItems(HorizontalAlign.Start)
.margin({ left: 10 })
.onClick(() => {
// 更新Tabs组件的选中状态
this.currentIndex = index;
});
}.height(100);
});
}.height(100)
.listDirection(Axis.Horizontal)
.scrollBar(BarState.Off);
}

build() {
Column() {
Flex({ alignItems: ItemAlign.Center }) {
this.TabBuilder();
}.width('100%').height(100);

  Tabs({ barPosition: BarPosition.Start, index: this.currentIndex, controller: this.tabsController }) {  
    TabContent() {  
      Text('翻译机的内容')  
        .fontSize(30)  
        .onClick(() => {  
          let promptShow = this.uiContext.getPromptAction();  
          promptShow.showToast({  
            message: '翻译机跳转'  
          });  
          // 需要自行创建一个PageA的@Entry页面  
          this.uiContext.getRouter().pushUrl({ url: 'pages/PageA' });  
        });  
    };  

    TabContent() {  
      Text('首页的内容')  
        .fontSize(30);  
    };  

    TabContent() {  
      Text('推荐的内容')  
        .fontSize(30);  
    };  
  }.barHeight(0)  
  .onAnimationStart((targetIndex: number) => {  
    this.currentIndex = targetIndex;  
  })  
  .onChange((index: number) => {  
    // currentIndex控制TabContent显示页签  
    this.currentIndex = index;  
    this.selectedIndex = index;  
  });  

}.height('100%').width('100%');  

}
}
总结
单例模式跳转时，由于也是复用路由栈内已有的页面实例，也可在本方案所述的页面生命周期内实现。

自己实现的插件只能点击跳转很不美观

问题现象
在应用中，每个接口都可能返回响应码Code，需要在接口拦截器中实现一个全局弹窗。由于接口是并发的，弹窗只能弹出一次。那么如何实现这个全局弹窗呢？此外，由于弹窗可能会在多个页面弹出（如启动页、登录页、主页等），这些页面可能会被销毁，这会导致弹窗无法正常显示。

效果预览

背景知识
使用弹窗组件时，可优先考虑自定义弹窗，便于自定义弹窗的样式与内容。通过CustomDialogController类显示自定义弹窗，不支持直接在类中定义和使用。通常需要将弹框逻辑封装成Builder或其他组件，以便在需要时调用。
可以使用@StorageLink与AppStorage中的key对应的属性建立双向数据同步，该属性可以和UI组件同步，且可以在应用业务逻辑中被访问。
解决方案
在并发接口拦截器中，由于弹窗弹出位置不确定且仅弹出一次，因此需要维护一个全局变量来保证弹窗的弹出状态。可以在AppStorage中定义弹窗弹出状态，并通过@StorageLink来获取弹窗是否曾弹出，具体实现可参考以下示例：

EntryAbility.ets的onWindowStageCreate方法里通过AppStorage定义关于弹框显示的全局属性，默认false不显示：
windowStage.loadContent('pages/Index', (err) => {
AppStorage.setOrCreate('showGlobalCustomDialog', false);
if (err.code) {
hilog.error(DOMAIN, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err));
return;
}
hilog.info(DOMAIN, 'testTag', 'Succeeded in loading the content.');
});
封装1个弹框实例类CustomDialogLayout.ets：
@CustomDialog
export struct CustomDialogLayout {
controller?: CustomDialogController;

build() {
Column() {
Text('Global Custom Dialog Test');
}
.justifyContent(FlexAlign.Center)
.alignItems(HorizontalAlign.Center)
.height(400);
}
}
Index.ets，在该页面import并创建实例import { CustomDialogLayout } from './CustomDialogLayout'，并且监听showGlobalCustomDialog属性值的改变并进行拉起弹窗动作：
import { CustomDialogLayout } from './CustomDialogLayout';

@Entry
@Component
struct Index {
@Provide('pathStack') pathStack: NavPathStack = new NavPathStack();
@StorageLink('showGlobalCustomDialog') @Watch('globalCustomDialogStateChange') showGlobalCustomDialog: boolean = false;

globalCustomDialogStateChange() {
if (this.showGlobalCustomDialog) {
if (this.dialogController != null) {
this.dialogController.open();
AppStorage.setOrCreate('showGlobalCustomDialog', false);
}
}
}

dialogController: CustomDialogController | null = new CustomDialogController({
builder: CustomDialogLayout({}),
autoCancel: true,
alignment: DialogAlignment.Center,
});

build() {
Navigation(this.pathStack) {
RelativeContainer() {
Button('跳转其他页面')
.fontSize(15)
.fontWeight(FontWeight.Bold)
.alignRules({
center: { anchor: 'container', align: VerticalAlign.Center },
middle: { anchor: 'container', align: HorizontalAlign.Center }
})

      .onClick(() => {  
        this.pathStack.pushPathByName('DetailPage', null);  
      });  
  }  
  .height('100%')  
  .width('100%');  
}  
.mode(NavigationMode.Stack);  

}
}
DetailPage.ets，在该页面设置showGlobalCustomDialog全局属性为true即可调起弹框：
@Builder
export function DetailPageBuilder() {
DetailPage();
}

@Component
export struct DetailPage {
@Consume('pathStack') pathStack: NavPathStack;

build() {
NavDestination() {
RelativeContainer() {
Button('promptAction弹窗')
.onClick(() => {
AppStorage.setOrCreate('showGlobalCustomDialog', true);
})
.alignRules({
center: { anchor: 'container', align: VerticalAlign.Center },
middle: { anchor: 'container', align: HorizontalAlign.Center }
});
};
}.title('DetailPage');
}
}
总结
在并发场景下，为了实现条件判断和控制弹窗弹出的行为，可以通过在AppStorage中维护一个全局变量，并使用@StorageLink进行同步监听。这种方法可以保证弹窗只弹出一次，从而避免重复弹出问题。

@meng-xi/uni-router

为 uni-app (Vue 3) 提供类似 vue-router 风格的路由管理系统（uni_modules 版本）。

⚠️ 仅支持 Vue 3 — 本库基于 Vue 3 Composition API（inject / ref / defineProps / defineEmits）和 app.provide 等 Vue 3 专属 API，不支持 uni-app Vue 2 项目。

特性

• vue-router 风格 API - push / replace / relaunch / back，零学习成本
• 路由守卫 - beforeEach / beforeResolve / afterEach / beforeEnter，支持 next(location, { mode }) 指定重定向方式
• 命名路由 & 路由元信息 - 通过 name 导航，meta 携带自定义数据
• TypeScript 类型提示 - 路由名称和路径自动补全与类型检查
• uni API 拦截 - 可选拦截原生导航 API，统一守卫流程（interceptUniApi）
• 页面间通信 - useUniEventChannel 启用后所有导航方式均支持 eventChannel 双向通信，目标页通过 usePageChannel() 获取通道，基于 uni.$emit 全局事件总线，粘性缓存确保时序安全
• 声明式导航 - RouterLink 组件，基于 uni navigator 封装，支持导航参数、动画、页面通信
• 页面参数传递 - params 传递复杂数据，不暴露在 URL，支持 persistent 持久化
• 查询参数增强 - queryInt() / queryNumber() / queryBool() 便捷解析
• 导航动画 - push / replace / back 支持动画参数，仅 App 端生效
• 路由状态同步 - syncRoute() 处理浏览器后退、物理返回键等场景
• 错误处理 - 完整的 RouterError / NavigationFailure 体系，onError 全局捕获
• 组合式 API - useRouter() / useRoute() / usePageChannel() 响应式访问路由与通信通道

安装

uni_modules（推荐）

将 mxuni-router 目录复制到项目的 uni_modules 目录下即可，无需 npm 安装。

npm

pnpm add @meng-xi/uni-router

npm 方式需将导入路径改为 @meng-xi/uni-router。

快速开始

1. 创建路由器

// main.ts  
import { createSSRApp } from 'vue'  
import { createRouter } from './uni_modules/mxuni-router/js_sdk/index.js'  
import App from './App.vue'  

const router = createRouter({  
    routes: [  
        { path: 'pages/index/index', name: 'home', meta: { title: '首页' } },  
        { path: 'pages/about/about', name: 'about', meta: { title: '关于', requireAuth: true } }  
    ],  
    strict: true,  
    interceptUniApi: true, // 拦截 uni 原生导航 API，确保守卫生效  
    useUniEventChannel: true // 启用内置通信管理器，所有导航方式支持页面间双向通信  
})  

export function createApp() {  
    const app = createSSRApp(App)  
    app.use(router)  
    return { app }  
}

2. 路由导航

import { useRouter, useRoute } from './uni_modules/mxuni-router/js_sdk/index.js'  

const router = useRouter()  
const route = useRoute() // 返回响应式引用，路由变化时自动更新  

// 路径导航  
await router.push({ path: '/pages/about/about', query: { id: '1' } })  

// 命名导航  
await router.push({ name: 'about' })  

// 页面参数传递（params 不暴露在 URL，支持复杂数据）  
await router.push({ path: '/pages/detail/detail', params: { info: { name: 'Tom' } } })  

// 返回（执行完整守卫链）  
await router.back()

3. 页面间通信

启用 useUniEventChannel 后，所有导航方式均返回 eventChannel，目标页通过 usePageChannel() 获取通道：

// ===== 发起页 =====  
const result = await router.push({ path: '/pages/detail/detail' })  
result.eventChannel?.on('ready', data => console.log('目标页已就绪:', data))  
result.eventChannel?.emit('data', { msg: '发给目标页的数据' })  

// ===== 目标页（detail.vue）=====  
import { usePageChannel } from './uni_modules/mxuni-router/js_sdk/index.js'  

const channel = usePageChannel() // 无 __nav_id 时返回 noopChannel，无需判空  
channel.on('data', data => console.log('收到发起页数据:', data))  
channel.emit('ready', { status: 'ok' }) // 粘性缓存：发起页尚未注册 on 也能收到

4. 路由守卫

router.beforeEach((to, from, next) => {  
    if (to.meta.requireAuth && !isLoggedIn()) {  
        // 使用 replace 模式重定向，避免登录页之后残留受保护页面的历史  
        next({ name: 'login', query: { redirect: to.fullPath } }, { mode: 'replace' })  
    } else {  
        next()  
    }  
})

5. 自动生成路由配置（推荐）

配合 @meng-xi/vite-plugin 的 generateRouter 插件，可从 pages.json 自动生成路由配置和类型声明：

pnpm add @meng-xi/vite-plugin -D

// vite.config.ts  
import { defineConfig } from 'vite'  
import uni from '@dcloudio/vite-plugin-uni'  
import { generateRouter } from '@meng-xi/vite-plugin'  

export default defineConfig({  
    plugins: [  
        uni(),  
        generateRouter({  
            pagesJsonPath: 'src/pages.json',  
            outputPath: 'src/router.config.ts',  
            dts: true,  
            metaMapping: {  
                navigationBarTitleText: 'title',  
                requireAuth: 'requireAuth'  
            }  
        })  
    ]  
})

然后在 main.ts 中导入生成的路由配置：

import { createRouter } from './uni_modules/mxuni-router/js_sdk/index.js'  
import routes from './router.config'  

const router = createRouter({ routes })

1.AI无法撤回到历史聊天记录

2.你们的AI只要一个项目，打开多个vue，会一起更改

3.你说你们有历史会话，但是他麻痹的会压缩，AI根本读不完

4.AI改了代码，不明确修改了哪里，我tm找了半天找到按钮，点击 接受 更改，哎你猜怎么着，无法接受，点了和没点一样，依然显示xxx行更改，

5.总结，你们tm要做AI给我做好了啊，基础的东西都没有，就en改啊

可以，换平台发就不要和上一篇太像。下面这版标题、结构、开头都重新换了，关键词还是保留 苹果4.3(a)、App Store审核、马甲包上架、申诉，适合发 CSDN、知乎、掘金、百家号这类平台。

App Store 审核遇到 4.3(a) 怎么办？一次真实处理思路分享

做 iOS 上架的人，基本都绕不开苹果审核 4.3(a)。尤其是工具类、教育类、内容类、马甲包上架项目，只要 App 和已有产品相似度比较高，就有可能被苹果认为是重复应用。很多开发者收到 4.3(a) 后，第一反应是直接申诉，但实际处理下来，单靠申诉通常很难解决问题。

我更建议把 4.3(a) 当成一次“产品独立性检查”。也就是说，苹果不是只看你有没有换名字、换图标，而是看这个 App 是否真的有独立的功能、独立的内容、独立的用户场景。

1. 4.3(a) 被拒，问题通常出在哪里？

苹果 4.3(a) 被拒，常见原因不是单点问题，而是多个相似点叠加造成的。

常见风险包括：

1. App 功能和旧版本或同类产品太接近；
2. 页面结构、首页布局、底部导航高度相似；
3. App Store 截图、标题、描述、关键词重复；
4. IPA 包里的资源文件、图片、模块命名相似；
5. 只是换了 icon、启动图、主题色，没有改变核心体验；
6. App 内还有旧项目名称、旧接口、旧隐私政策或旧文案。

很多时候，开发者觉得自己已经改了不少，但从审核人员视角看，可能还是同一个模板。

2. 为什么直接申诉效果不好？

收到 4.3(a) 后，如果直接回复“我们的 App 是原创的，请重新审核”，通常说服力不够。因为苹果更关注 App 本身的实际变化，而不是开发者的口头解释。

如果 App 没有明显改动，截图没换，功能没变，描述还是原来的表达，那么即使申诉，也很容易继续被拒。

所以处理顺序应该是：

先找相似点，再做差异化，再写申诉说明，最后重新提交。

3. 真正有效的处理方式是什么？

第一步，先改定位。
不要只把 App 描述成“工具”“学习软件”“生活服务”。要具体到目标人群和使用场景，比如儿童启蒙、考试练习、口语跟读、企业内部管理、个人效率记录等。定位清楚以后，审核备注和产品描述才有支撑。

第二步，改核心功能。
如果只是首页、分类、详情、会员、我的这几个页面来回套，很容易被认为模板化。可以调整功能入口、内容分类、任务流程、数据展示方式，让用户使用路径发生变化。

第三步，改 UI 和截图。
UI 不要只换颜色。首页结构、图标风格、按钮样式、卡片布局、空页面、引导页都应该重新设计。App Store 截图也要单独做，不能几个包共用一套模板。

第四步，清理资源和旧内容。
重点检查图片、音频、banner、课程、文章、接口路径、旧产品名称、旧客服信息、旧隐私政策链接。这些细节很容易让审核认为 App 是复制出来的。

第五步，检查 IPA 相似度。
如果是从旧项目改出来的，最好在提交前做一次包体检查，看看资源结构、模块命名、配置文件、无用代码是否还保留太多旧项目痕迹。

4. 申诉应该怎么写？

4.3(a) 的申诉不要写得太硬，也不要说“我们没有问题”。更合适的写法是承认苹果的审核关注点，然后说明你已经完成了哪些调整。

可以这样写：

Hello App Review Team,
Thank you for your review.
We understand the concern regarding Guideline 4.3(a). After receiving the rejection, we carefully reviewed the app and made several updates to better reflect its independent value.
This app is designed for [目标用户] and focuses on [核心使用场景]. In this version, we updated the user interface, adjusted the feature structure, revised the App Store metadata, redesigned screenshots, and removed unrelated legacy content.
The app now provides a clearer user experience and independent functionality for its intended users.
We kindly ask you to review the updated version again. Thank you.

这类申诉的重点不是解释太多，而是让审核人员看到你已经针对问题做了实际调整。

5. 重新提交前的检查清单

提交前建议逐项检查：

1. App 名称、副标题、关键词是否独立；

2. 描述是否围绕当前 App 重新写；

3. 截图是否重新设计；

4. 首页和核心页面是否有明显变化；

5. 功能流程是否不是简单复制；

6. 是否删除旧项目残留信息；

7. 隐私政策和用户协议是否匹配；

8. 权限申请是否合理；

9. 是否存在空功能、假功能、不可用功能；

10. IPA 包内资源和代码是否相似度过高。

11. 总结

苹果审核 4.3(a) 并不是不能解决，但不能只靠一句申诉。真正有效的办法，是把 App 从产品定位、功能结构、UI 设计、资源内容、元数据文案、包体结构几个方面重新整理。

对于马甲包上架来说，最重要的一点是：不要让它看起来像复制包，而要让它成为一个有独立场景、独立功能、独立价值的 App。这样再配合清晰的申诉说明，重新提交通过的概率才会更高。

问题现象
Swiper如何实现卡片堆叠样式：

上下堆叠：Swiper内容像卡片堆叠，在底部留部分空间显示下一页的内容，上下滑实现卡片切换。
左右堆叠：Swiper内容像卡片堆叠，在右侧留部分空间显示下一页的内容，左右滑实现卡片切换。
背景知识
Swiper组件提供滑动轮播显示的能力。Swiper本身是一个容器组件，当设置了多个子组件后，可以对这些子组件进行轮播显示。
Stack是堆叠容器，子组件按照顺序依次入栈，后一个子组件覆盖前一个子组件。
gesture可以为组件绑定手势方法进行相应处理，如滑动手势事件PanGesture。
animateTo指定由于闭包代码导致的状态变化插入过渡动效。
解决方案
上下堆叠实现。
自定义实现卡片堆叠的组件：使用Stack组件堆叠需要展示的图片，设置最上面的图片向上偏移部分距离，露出下一张图片的底部。为Stack绑定上下滑动的手势处理，实现切换图片逻辑，同时使用animateTo接口设置图片切换动画。

export class SwiperData {
imageSrc: Resource;

constructor(imageSrc: Resource) {
this.imageSrc = imageSrc;
}
}

@Component
export struct SwiperStackComponent {
@Link currentIndex: number;
@Prop swiperData: SwiperData[];
private halfCount: number = Math.floor(3 / 2);
private automaticSlidingDuration: number = 300;

aboutToAppear(): void {
this.currentIndex = 0;
}

// 修改堆叠方向系数计算
getImgCoefficients(index: number): number {
const coefficient = this.currentIndex - index;
const tempCoefficient = Math.abs(coefficient);
if (tempCoefficient <= this.halfCount) {
return coefficient;
}
const dataLength = this.swiperData.length;
let tempOffset = dataLength - tempCoefficient;
if (tempOffset <= this.halfCount) {
return coefficient > 0 ? -tempOffset : tempOffset;
}
return 0;
}

// 修改堆叠方向偏移量计算
getOffSet(index: number): number {
let offsetIndex = this.getImgCoefficients(index);
const tempOffset = Math.abs(offsetIndex);
let offset = 0;
if (tempOffset === 1) {
if (offsetIndex === 1) {
offsetIndex = -1;
}
offset = 50 * offsetIndex;
}
return -offset;
}

startAnimation(isLeft: boolean, duration: number): void {
this.getUIContext().animateTo({ duration: duration, }, () => {
const dataLength: number = this.swiperData.length;
const tempIndex: number = isLeft ? this.currentIndex + 1 : this.currentIndex - 1 + dataLength;
this.currentIndex = tempIndex % dataLength;
});
}

build() {
Stack() {
ForEach(this.swiperData, (item: SwiperData, index: number) => {
Stack({ alignContent: Alignment.Bottom }) {
Image(item.imageSrc)
.objectFit(ImageFit.Cover)
.width('100%')
.height('100%')
.borderRadius(8);
}
.offset({ x: 0, y: this.getOffSet(index) })
.shadow(ShadowStyle.OUTER_DEFAULT_SM)
.backgroundColor(Color.White)
.borderRadius(8)
.blur(index !== this.currentIndex ? 12 : 0)
// 通过animateTo实现动画并且同时改变currentIndex数据中间值来判断组件zIndex实现切换动画
.zIndex(index !== this.currentIndex && this.getImgCoefficients(index) === 0 ?
0 : 2 - Math.abs(this.getImgCoefficients(index)))
.width(310)
.height(index !== this.currentIndex ? 130 : 180);
});
}
.height(200)
.width('100%')
.gesture(
PanGesture({ direction: PanDirection.Vertical })
.onActionStart((event: GestureEvent) => {
this.startAnimation(event.offsetY < 0, this.automaticSlidingDuration);
})
)
.alignContent(Alignment.Center)
.padding({ left: 12, right: 12, top: 12 });
}
}
在页面中直接使用上面封装好的SwiperStackComponent即可，示例如下：传给SwiperStackComponent要堆叠的图片。

更新后如果编译代码时出现下边的这种情况

如果发现勾选了 取消勾选 然后点击右下角的应用；重启HBuilder X 查看问题是否已经解决；

根据官方说明，HBuilder X 5.11 及以上版本内置的 Node.js 已升级至 22.22.2，不再支持 Windows 8.1 及以下系统，因此要求运行环境必须为 Windows 8.1 或更高版本。
需要特别注意的是：如果您的电脑系统本身高于 Windows 8.1，但为 HBuilder X 勾选了“兼容模式”（例如兼容 Windows 7 或 8），HBuilder X 在运行时会强制模拟该低版本环境。这会导致内置的 Node.js 无法正常运行，进而引发编译卡死问题，具体表现为一直提示【uni-app (x)项目编译插件正在启动中】或报错“当前设备 Windows 版本低”。请取消兼容模式以确保正常运行。

服务器超级稳定，根本不会中断。
ai卡了中断了也没事，根本不会白白烧你的token。

问题现象
HarmonyOS的Toast接口，不支持设定圆角样式。如何实现类似其他平台的Toast样式？

效果预览
点击放大

背景知识
不依赖UI组件的全局自定义弹出框(openCustomDialog)，适用于在相对应用复杂的场景来实现自定义弹出框，相较于CustomDialogController优势点在于页面解耦，支持动态刷新。
ArkUI提供轻量的UI元素复用机制@Builder，其内部UI结构固定，仅与使用方进行数据传递。可将重复使用的UI元素抽象成函数，在build函数中调用。
Text组件可以自定义展示文本框的UI样式，包括边框圆角、内边距等。
setTimeout接口支持设置一个定时器，该定时器在定时器到期后执行一个函数。
解决方案
如果需要实现类似其他平台的Toast样式，可借助自定义弹窗实现。

主要实现思路为，借助Text组件自定义类似其他平台Toast的UI样式，并封装为@Builder构建函数，将该函数传入ComponentContent创建弹窗对象，通过getUIContext开启该弹窗对象，开启后执行setTimeout，等待指定的时间后，执行关闭弹窗对象。详细步骤如下：

配置ToastContent组件属性并封装为@Builder构建函数。
@Component
struct ToastContent {
public text: string = '';
public clickText: string = '';
public clickListener = () => {
};
private textList: string[] = [];

aboutToAppear(): void {
if (this.clickText.length > 0) {
this.textList = this.text.split(this.clickText);
}
}

build() {
Column() {
if (this.clickText === '') {
Text(this.text).toastText();
} else {
Text() {
ForEach(this.textList, (item: string, num: number) => {
Span(item);
if (num < this.textList.length - 1) {
Span(this.clickText).fontColor(Color.Yellow);
}
});
}.onClick(this.clickListener).toastText();
}
}
.borderRadius(5)
.backgroundColor(Color.Black)
.padding(10)
.justifyContent(FlexAlign.SpaceBetween)
.margin({ left: '5%', right: '5%' });
}
}

// 封装Toast的@Builder方法
@Builder
function buildText(params: Params) {
ToastContent({ text: params.text, clickText: params.clickText, clickListener: params.clickListener });
}

// 封装公共样式
@Extend(Text)
function toastText() {
.fontSize(20)
.fontColor(Color.White);
}
创建Toast类，并创建构造方法与Toast实例方法。
/**

• 封装全局蓝色浮动提示，支持点击
  */
  export class Toast {
  private toastParams: Params;

  constructor(text: string, time: number = 2000) {
  this.toastParams = new Params(text, time);
  }

  setClick(clickText: string, clickListener: () => void): Toast {
  this.toastParams.setClick(clickText, clickListener);
  return this;
  };

  async show() {
  let uiContext = AppStorage.get('currentUIContext') as UIContext;
  let click = this.toastParams.clickListener;
  let contentNode = new ComponentContent(uiContext, wrapBuilder(buildText), this.toastParams);
  uiContext.getPromptAction().openCustomDialog(contentNode, {
  showInSubWindow: this.toastParams.clickText === '' ? false : true,
  isModal: false,
  offset: { dx: 0, dy: '10%' }
  }).then(() => {
  setTimeout(() => {
  uiContext.getPromptAction().closeCustomDialog(contentNode);
  }, this.toastParams.time);
  });
  this.toastParams.clickListener = () => {
  click();
  uiContext.getPromptAction().closeCustomDialog(contentNode);
  };
  };
  }
  创建并弹出Toast，并且可以在Toast的setClick回调方法内实现点击Toast后的逻辑，如页面跳转。
  new Toast('点击Toast后屏幕将退出横屏，进入到竖屏状态', 3000).setClick('关闭自动添加', () => {
  this.windowClass.setPreferredOrientation(window.Orientation.PORTRAIT);
  this.pathStack.pushPathByName('DetailPage', null);
  }).show();
  完整示例参考如下：

Index.ets。
import { common } from '@kit.AbilityKit';
import { Toast } from './ToastContent';
import { window } from '@kit.ArkUI';

@Entry
@Component
struct Index {
pathStack: NavPathStack = new NavPathStack();
private context = this.getUIContext().getHostContext() as common.UIAbilityContext;
private windowClass = (this.context as common.UIAbilityContext).windowStage.getMainWindowSync();

setOrientation(orientation: number) {
this.windowClass.setPreferredOrientation(orientation).then(() => {
}).catch(() => {
});
}

async aboutToAppear(): Promise<void> {
await this.windowClass.setPreferredOrientation(window.Orientation.LANDSCAPE);
AppStorage.setOrCreate('currentUIContext', this.getUIContext());
}

build() {
Navigation(this.pathStack) {
RelativeContainer() {
Column() {
Text('我的记录')
.fontSize(50)
.width('100%')
.textAlign(TextAlign.Center)
.fontWeight(FontWeight.Bold)
Button('保存')
.onClick(() => {
new Toast('点击Toast后屏幕将退出横屏，进入到竖屏状态', 3000).setClick('关闭自动添加', () => {
this.windowClass.setPreferredOrientation(window.Orientation.PORTRAIT);
this.pathStack.pushPathByName('DetailPage', null);
}).show();
})
.backgroundColor(Color.Blue)
.fontColor(Color.White)
}
.alignRules({
center: { anchor: 'container', align: VerticalAlign.Center },
middle: { anchor: 'container', align: HorizontalAlign.Center }
})
}
.width('100%')
}
.mode(NavigationMode.Stack)
.height('100%')
.width('100%')
.height('100%')
.hideTitleBar(true)
}
}

问题现象
在Text中显示文本时，如果文本超过一定长度，通常会有超出部分隐藏与显示的需求，例如：当最多显示的行数为2，组件宽度比例为0.4时，该如何实现？

背景知识
measureText方法能够根据文本信息计算文本宽度。
getAllDisplays方法能够获取display对象，display对象的width属性为屏幕的宽度。
点击放大

解决方案
首先设定的文本长度计算方式：设定文本长度 = 屏幕宽度 最大行数 组件宽度比例。屏幕宽度可以使用getAllDisplays获取。
然后使用measureText方法测量实际文本宽度，比较“设定文本长度”与“实际文本宽度”进行大小比较，判断是否需要隐藏。
当需要隐藏时，只展示“设定长度”的文本内容，超出部分显示为“...”。当点击“…”时将该文本变为“…收起”，显示隐藏部分内容。
完整示例参考如下：

import { MeasureUtils } from '@kit.ArkUI';
import curves from '@ohos.curves';
import { BusinessError } from '@ohos.base';
import display from '@ohos.display';

@Entry
@Component
struct Index {
// 长文本
longMessage: string = '走在繁华的城市街头，明空感到无比紧张。他的心跳如雷鼓般擂动着胸膛，使得身上的伪装仿佛随时都要被揭开。然而，他仍然保持着冷静，凭借着过人的胆识与智慧，成功地躲过了敌人的层层封锁。\n' +
'\n' +
'　　最终，明空来到了敌对帮派的老巢。此时此刻，那里的守卫正沉浸在欢庆的氛围中，丝毫没有察觉到即将来临的危机。明空深吸一口气，压抑住内心的激动，悄然潜入了这座古老的建筑。';
// 最大显示行数
@State lines: number = 2;
// 长文本状态（展开 or 收起）
@State collapseText: string = '...';
// 屏幕宽度（单位px）
screenWidth: number = 0;
// 是否需要显示"展开"字样（注：当文本长度较短时就不需要“展开”）
@State isExpanded: boolean = false;
uiContext: UIContext = this.getUIContext();

// 测量文本宽度（单位px）

});
// 获取当前所有的display对象
promise: Promise<Array<display.Display>> = display.getAllDisplays();

aboutToAppear() {
console.info(文本宽度为：${this.textWidth});
this.promise.then((data: Array<display.Display>) => {
console.info(所有的屏幕信息：${JSON.stringify(data)});
// 单位为像素
this.screenWidth = data[0]["width"];
// 屏幕宽度 最大行数 组件宽度比例 和 文字测量宽度
this.isExpanded = this.screenWidth this.lines 0.4 <= this.textWidth;
}).catch((err: BusinessError) => {
console.error(Failed to obtain all the display objects. Code: ${JSON.stringify(err)});
});
}

build() {
