兼容性验证

在以下环境验证通过：

  • RNOH: 0.72.90; SDK: HarmonyOS 6.0.0 Release SDK; IDE: DevEco Studio 6.0.2; ROM: 6.0.0

📦 安装步骤

1. 安装依赖

# RN 0.72 版本（本项目使用）
npm install @react-native-ohos/react-native-tts@4.1.3-rc.1

# RN 0.77 版本
npm install @react-native-ohos/react-native-tts@4.2.0-rc.1

# 或者使用 yarn
yarn add @react-native-ohos/react-native-tts

2. 验证安装

安装完成后，检查 package.json 文件：

{
  "dependencies": {
    "@react-native-ohos/react-native-tts": "^4.1.3-rc.1"
  }
}

3. 类型定义配置（重要）

该库默认导出的是 react-native-tts，需要创建类型定义文件以获得完整的 TypeScript 类型支持。

文件路径: src/types/react-native-tts.d.ts

declare module "react-native-tts" {
  interface Voice {
    id: string;
    name: string;
    language: string;
    quality?: number;
    latency?: number;
    networkRequired?: boolean;
    notInstalled?: boolean;
  }

  interface SpeakOptions {
    rate?: number;
    pitch?: number;
    language?: string;
    voice?: string;
    onWordBoundary?: boolean;
    skipTransform?: boolean;
  }

  interface TtsStartEvent {
    utteranceId: string;
  }

  interface TtsProgressEvent {
    utteranceId: string;
    location: number;
    length: number;
  }

  interface TtsFinishEvent {
    utteranceId: string;
  }

  interface TtsCancelEvent {
    utteranceId: string;
  }

  interface TtsErrorEvent {
    utteranceId: string;
    error: string;
  }

  type TtsEventType =
    | "tts-start"
    | "tts-progress"
    | "tts-finish"
    | "tts-cancel"
    | "tts-error";

  interface TtsStatic {
    speak(text: string, options?: SpeakOptions): Promise<string>;
    stop(): void;
    pause(): void;
    resume(): void;
    setDefaultRate(rate: number): void;
    setDefaultPitch(pitch: number): void;
    setDefaultLanguage(language: string): void;
    setDefaultVoice(voiceId: string): void;
    setDucking(enabled: boolean): void;
    setIgnoreSilentSwitch(ignore: boolean): void;
    voices(): Promise<Voice[]>;
    engines(): Promise<any[]>;
    getInitStatus(): Promise<void>;
    requestInstallEngine(): Promise<void>;
    requestInstallData(): Promise<void>;
    addEventListener(
      event: "tts-start",
      callback: (event: TtsStartEvent) => void
    ): void;
    addEventListener(
      event: "tts-progress",
      callback: (event: TtsProgressEvent) => void
    ): void;
    addEventListener(
      event: "tts-finish",
      callback: (event: TtsFinishEvent) => void
    ): void;
    addEventListener(
      event: "tts-cancel",
      callback: (event: TtsCancelEvent) => void
    ): void;
    addEventListener(
      event: "tts-error",
      callback: (event: TtsErrorEvent) => void
    ): void;
    removeEventListener(event: TtsEventType, callback: (event: any) => void): void;
  }

  const Tts: TtsStatic;
  export default Tts;
}

在tpconfig.json中添加配置：

{
  "include": [
    "**/*.ts",
    "**/*.tsx"
  ],
}

🔧 HarmonyOS 平台配置 ⭐

Link 配置

版本 是否支持 autolink RN 框架版本
~4.2.0 No 0.77
~4.1.3 Yes 0.72
<= 4.1.1-0.0.3@deprecated No 0.72

1. 在工程根目录的 oh-package.json5 添加 overrides 字段

打开 harmony/oh-package.json5，添加以下配置：

{
  // ... 其他配置
  "overrides": {
    "@rnoh/react-native-openharmony": "0.72.90"
  }
}

2. 引入原生端代码

打开 harmony/entry/oh-package.json5，添加以下依赖：

"dependencies": {
  "@react-native-ohos/react-native-tts": "file:../../node_modules/@react-native-ohos/react-native-tts/harmony/rn_tts.har"
}

点击右上角的 sync 按钮，或者在终端执行：

cd entry
ohpm install

3. 配置 CMakeLists

打开 entry/src/main/cpp/CMakeLists.txt，添加：

project(rnapp)
cmake_minimum_required(VERSION 3.4.1)
set(RNOH_APP_DIR "${CMAKE_CURRENT_SOURCE_DIR}")
+ set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../react-native-harmony/harmony/cpp")

add_subdirectory("${RNOH_CPP_DIR}" ./rn)

# RNOH_BEGIN: manual_package_linking_1
+ add_subdirectory("${OH_MODULES}/@react-native-ohos/react-native-tts/src/main/cpp" ./rn_tts)
# RNOH_END: manual_package_linking_1

add_library(rnoh_app SHARED
    "./PackageProvider.cpp"
    "${RNOH_CPP_DIR}/RNOHAppNapiBridge.cpp"
)

target_link_libraries(rnoh_app PUBLIC rnoh)

# RNOH_BEGIN: manual_package_linking_2
+ target_link_libraries(rnoh_app PUBLIC rnoh_tts)
# RNOH_END: manual_package_linking_2

4. 引入 RNTTSPackage

打开 entry/src/main/cpp/PackageProvider.cpp，添加：

#include "RNOH/PackageProvider.h"
+ #include "RNTTSPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
       +  std::make_shared<RNTTSPackage>(ctx)
    };
}

5. 在 ArkTS 侧引入 RNTTSPackage

打开 entry/src/main/ets/RNPackagesFactory.ts，添加：

import { RNTTSPackage } from '@react-native-ohos/react-native-tts/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new RNTTSPackage(ctx)
  ];
}

⚠️ 注意事项

遗留问题

问题 说明 Issue
三方引擎相关功能 无法实现三方引擎功能 issue#2
语言类型限制 目前只支持中文 issue#3
setDucking 无法实现降低其他音频音量 issue#4
setIgnoreSilentSwitch 无法实现忽略静音开关 issue#5
setDefaultVoice 无法设置默认语音 issue#6
边合成边播放 边合成边播放功能问题 issue#7
参数无效 skipTransform、onWordBoundary 参数无效 issue#8

使用建议

  1. 初始化检查：使用前建议调用 getInitStatus() 检查 TTS 引擎是否已初始化
  2. 事件监听：建议添加事件监听器以获取朗读状态
  3. 资源释放：组件卸载时调用 stop() 停止朗读
  4. 语速音调：根据实际场景调整合适的语速和音调

常见问题

Q: 朗读没有声音？

A: 检查设备音量设置，确保媒体音量已开启。同时确认 TTS 引擎已正确初始化。

Q: 只支持中文吗？

A: 目前 HarmonyOS 版本存在语言类型限制，主要支持中文。其他语言支持正在完善中。

Q: 如何切换不同的语音？

A: 使用 voices() 获取可用语音列表，但目前 setDefaultVoice 功能暂不支持。

Flutter 三方库 dio 的鸿蒙化适配指南：构建跨平台网络请求应用

良好的数据模型设计是应用架构的基础。在Flutter中,我们通常使用Dart类来定义数据模型,并通过工厂构造函数实现JSON数据的反序列化。对于待办事项数据,我们定义了TodoItem类,包含四个字段：userId表示用户标识,id表示待办事项的唯一标识,title表示待办事项的标题,completed表示是否已完成。数据模型的实现代码如下：TodoItem({});
