@bingtang-rn/react-native-loader-kit for HarmonyOS\r\n\r\n本项目基于 [react-native-loader-kit](https://github.com/maitrungduc1410/react-native-loader-kit) 开发，为 React Native 鸿蒙（OpenHarmony）适配版本。如果在使用过程中有任何问题，可以在GitCode提Issue，会及时跟进。issue地址：[issues](https://gitcode.com/rn_ohos_plugin/react_native_loader_kit/issues)。\r\n\r\n## 版本对应关系\r\n\r\n| 鸿蒙适配包版本 | 原始库版本 | 支持 RN 版本 | Autolink | 编译 API 版本 |\r\n| ------------ | ---------- | ------------ | -------- | ------------- |\r\n| 4.1.0 | 4.1.0 | 0.72+ | 是 | API17+ |\r\n\r\n## 安装\r\n\r\n```bash\r\nnpm install @bingtang-rn/react-native-loader-kit\r\n```\r\n\r\n## 使用\r\n\r\n```tsx\r\nimport { LoaderKitView } from 'react-native-loader-kit';\r\n\r\n// Basic usage\r\n<LoaderKitView\r\n  name=\"BallPulse\"\r\n  color=\"blue\"\r\n  animationSpeedMultiplier={1.0}\r\n  style={styles.loader}\r\n/>\r\n\r\n// Switch animation by name (32 types available)\r\n<LoaderKitView name=\"CircleStrokeSpin\" color=\"#ff0000\" />\r\n\r\n// Speed up (duration = baseDuration / speed)\r\n<LoaderKitView name=\"BallGridPulse\" color=\"green\" animationSpeedMultiplier={2.0} />\r\n```\r\n\r\n> import 时使用原库名 `'react-native-loader-kit'`，而非鸿蒙包名。RNOH alias 会自动重定向到 `@bingtang-rn/react-native-loader-kit`。\r\n\r\n**平台差异**：\r\n- HarmonyOS 支持 32 种动画（含原 iOS 专属 `BallRotateChase` 和 `CircleStrokeSpin`），与 iOS 对齐。\r\n- `SquareSpin` / `TriangleSkewSpin` 的 3D 翻转用 `scaleX/scaleY + rotate` 近似（Canvas 2D 无 3D 透视变换），视觉接近但不完全等价。\r\n- `AudioEqualizer` 用逐帧高度插值替代 iOS path 动画，视觉效果等价。\r\n\r\n**权限要求**：\r\n- 无需任何系统权限。纯 Canvas 绘制 + setInterval 动画，不涉及网络、文件、传感器等。\r\n\r\n## Link\r\n\r\n| 版本 | 是否支持 Autolink |\r\n|------|------------------|\r\n| 当前版本 | 是 |\r\n\r\n如使用版本支持 Autolink 且工程已接入，可跳过手动配置。\r\n\r\n<details>\r\n<summary>Manual Link 配置</summary>\r\n\r\n> **说明**：本模块需要同时在 C++ 侧和 ETS 侧注册 Package。\r\n\r\n### 1. Overrides RN SDK\r\n\r\n在工程根目录 `oh-package.json5` 添加：\r\n\r\n```json\r\n{\r\n  \"overrides\": {\r\n    \"@rnoh/react-native-openharmony\": \"./react_native_openharmony\"\r\n  }\r\n}\r\n```\r\n\r\n### 2. 引入原生端依赖\r\n\r\n打开 `entry/oh-package.json5`，添加：\r\n\r\n```json\r\n\"dependencies\": {\r\n  \"@bingtang-rn/react-native-loader-kit\": \"file:../../node_modules/@bingtang-rn/react-native-loader-kit/harmony/loader_kit.har\"\r\n}\r\n```\r\n\r\n执行 `ohpm install`。\r\n\r\n### 3. 配置 CMakeLists\r\n\r\n打开 `entry/src/main/cpp/CMakeLists.txt`，添加：\r\n\r\n```cmake\r\nset(OH_MODULES \"${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules\")\r\n\r\nadd_subdirectory(\"${OH_MODULES}/@bingtang-rn/react-native-loader-kit/src/main/cpp\" ./loader_kit)\r\n\r\ntarget_link_libraries(rnoh_app PUBLIC loader_kit)\r\n```\r\n\r\n### 4. 注册 Package（C++ 侧）\r\n\r\n打开 `entry/src/main/cpp/PackageProvider.cpp`，添加：\r\n\r\n```cpp\r\n#include \"LoaderKitPackage.h\"\r\n\r\nstd::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {\r\n    return {\r\n        std::make_shared<LoaderKitPackage>(ctx),\r\n    };\r\n}\r\n```\r\n\r\n### 5. 注册 Package（ETS 侧）\r\n\r\n打开 `entry/src/main/ets/RNPackagesFactory.ets`，添加：\r\n\r\n```typescript\r\nimport { LoaderKitPackage } from '@bingtang-rn/react-native-loader-kit/ts';\r\n\r\nexport function createRNPackages(ctx: RNPackageContext): RNPackage[] {\r\n  return [\r\n    new LoaderKitPackage(ctx),\r\n  ];\r\n}\r\n```\r\n\r\n</details>\r\n\r\n## 属性 / API\r\n\r\n| API | 描述 | 参数 | 返回值 | HarmonyOS 支持 |\r\n|-----|------|------|--------|----------------|\r\n| LoaderKitView | Fabric 加载动画组件 | `name: string, color?: ColorValue, animationSpeedMultiplier?: number` | — | ✅ 完全支持 |\r\n| name | 动画指示器名称（32 种） | `IndicatorName` | — | ✅ 完全支持 |\r\n| color | 动画图形颜色 | `ColorValue` | — | ✅ 完全支持 |\r\n| animationSpeedMultiplier | 动画速度倍率（默认 1.0） | `number` | — | ✅ 完全支持 |\r\n| COMMON_INDICATORS | 通用动画名常量（30 种） | — | `readonly IndicatorName[]` | ✅ 完全支持 |\r\n| IOS_ONLY_INDICATORS | iOS 专属动画名常量（2 种） | — | `readonly IndicatorName[]` | ✅ 完全支持 |\r\n| ALL_INDICATORS | 全部动画名常量（32 种） | — | `readonly IndicatorName[]` | ✅ 完全支持 |\r\n| isIndicatorAvailableOnPlatform | 检查动画在平台是否可用 | `(indicator, platform: 'ios'\\|'android'\\|'harmony')` | `boolean` | ✅ 完全支持 |\r\n| getAvailableIndicators | 获取平台可用动画列表 | `(platform: 'ios'\\|'android'\\|'harmony')` | `readonly IndicatorName[]` | ✅ 完全支持 |\r\n\r\n### 平台差异\r\n- `SquareSpin` / `TriangleSkewSpin`：Canvas 2D 无 3D 透视变换，用 `scaleX/scaleY + rotate` 近似 3D 翻转效果，视觉接近但无透视变形。\r\n- `AudioEqualizer`：iOS 使用 path 关键帧动画，鸿蒙端改为逐帧高度插值绘制 rounded rect，视觉效果等价。\r\n\r\n### 使用限制\r\n- 无系统权限要求。\r\n- Example 中 32 个动画同时运行时各有独立 Canvas + setInterval，大量并发可能影响帧率。\r\n\r\n## 快速验证（运行 Example）\r\n\r\n### 前置条件\r\n\r\n| 依赖 | 版本要求 |\r\n|------|----------|\r\n| Node.js | >= 18 |\r\n| DevEco Studio | 5.0+ / 6.0+ |\r\n| HarmonyOS SDK | API 17+ |\r\n\r\n### 运行步骤\r\n\r\n**1. 克隆仓库**\r\n\r\n```bash\r\ngit clone <仓库地址>\r\ncd <仓库目录>\r\n```\r\n\r\n**2. 安装依赖并构建**\r\n\r\n```bash\r\nnpm install --legacy-peer-deps\r\nnpm pack           # 生成 tgz 包（会自动触发 prepare 构建 JS 产物）\r\n```\r\n\r\n**3. 进入 example 目录，安装依赖**\r\n\r\n```bash\r\ncd example\r\nnpm install --legacy-peer-deps\r\n```\r\n\r\n**4. 生成 JS Bundle**\r\n\r\n```bash\r\nnpm run dev\r\n```\r\n\r\n产物：`harmony/entry/src/main/resources/rawfile/bundle.harmony.js`\r\n\r\n**5. 用 DevEco Studio 打开鸿蒙工程**\r\n\r\n- 打开 DevEco Studio\r\n- 选择 `example/harmony` 目录\r\n- 等待 Sync 完成\r\n\r\n**6. 编译并运行 HAP**\r\n\r\n在 DevEco Studio 中点击运行按钮，将 HAP 安装到设备/模拟器。\r\n\r\n> **注意**：Example 中已预置插件依赖和 Package 注册，无需手动配置 Link。\r\n\r\n## 约束与限制\r\n\r\n### 兼容性\r\n\r\n- RNOH: 0.72+\r\n- HarmonyOS SDK: API 17+\r\n- DevEco Studio: 5.0+\r\n\r\n## 遗留问题\r\n\r\n无（或列出已知问题）\r\n\r\n## 开源协议\r\n\r\n本项目基于 [MIT 协议](https://github.com/maitrungduc1410/react-native-loader-kit/blob/main/LICENSE)，详见 [LICENSE](./LICENSE) 文件。\r\n","readmeFilename":"README.md"}
