1. 项目的目录结构及介绍

react-native-gesture-recognizers/
├── src/
│   ├── GestureHandler.js
│   ├── GestureRecognizer.js
│   ├── PanGestureRecognizer.js
│   ├── PinchGestureRecognizer.js
│   ├── RotationGestureRecognizer.js
│   └── SwipeGestureRecognizer.js
├── index.js
├── package.json
├── README.md
└── .gitignore

• src/: 包含所有手势识别器的实现文件。
  • GestureHandler.js: 手势处理器的基类。
  • GestureRecognizer.js: 手势识别器的基类。
  • PanGestureRecognizer.js: 处理平移手势的识别器。
  • PinchGestureRecognizer.js: 处理捏合手势的识别器。
  • RotationGestureRecognizer.js: 处理旋转手势的识别器。
  • SwipeGestureRecognizer.js: 处理滑动手势的识别器。
• index.js: 项目的入口文件。
• package.json: 项目的配置文件，包含依赖项和脚本。
• README.md: 项目的说明文档。
• .gitignore: Git 忽略文件配置。

2. 项目的启动文件介绍

index.js 是项目的入口文件，负责初始化并导出手势识别器模块。以下是 index.js 的简要内容：

import GestureHandler from './src/GestureHandler';
import GestureRecognizer from './src/GestureRecognizer';
import PanGestureRecognizer from './src/PanGestureRecognizer';
import PinchGestureRecognizer from './src/PinchGestureRecognizer';
import RotationGestureRecognizer from './src/RotationGestureRecognizer';
import SwipeGestureRecognizer from './src/SwipeGestureRecognizer';

export {
  GestureHandler,
  GestureRecognizer,
  PanGestureRecognizer,
  PinchGestureRecognizer,
  RotationGestureRecognizer,
  SwipeGestureRecognizer,
};

该文件导出了所有手势识别器的类，供其他模块使用。

3. 项目的配置文件介绍

package.json 是项目的配置文件，包含了项目的元数据、依赖项和脚本。以下是 package.json 的简要内容：
