一、核心知识点：Transform 变换完整核心用法

1. 用到的纯内置组件与API

所有能力均为 RN 原生自带，全部从 react-native 核心包直接导入，无任何外部依赖、无任何第三方库，鸿蒙端无任何兼容问题，也是实现变换的全部核心能力，基础易理解、易复用，无多余，所有变换功能均基于以下组件/API 原生实现：

核心组件/API 作用说明 鸿蒙适配特性
Animated RN 原生动画库，实现变换动画效果 ✅ 鸿蒙端变换动画流畅，性能优秀，无兼容问题
View 核心容器组件，实现组件布局、内容容器、样式容器等 ✅ 鸿蒙端布局无报错，布局精确、圆角、边框、背景色属性完美生效
Text 显示变换提示、状态信息等，支持多行文本、不同颜色状态 ✅ 鸿蒙端文字排版精致，字号、颜色、行高均无适配异常
StyleSheet 原生样式管理，编写鸿蒙端最佳的变换样式：容器、变换元素，无任何不兼容CSS属性 ✅ 符合鸿蒙官方视觉设计规范，颜色、圆角、边框、间距均为真机实测最优
useState / useEffect React 原生钩子，管理变换状态、动画状态等核心数据，控制实时更新、状态切换 ✅ 响应式更新无延迟，状态切换流畅无卡顿，计算结果实时显示

二、实战核心代码解析：在展示完整代码之前，我们先深入理解变换实现的核心逻辑，掌握这些核心代码后，你将能够举一反三应对各种变换相关的开发需求。

1. 平移变换

实现最基本的平移变换。

import { Animated } from 'react-native';

const translateX = useRef(new Animated.Value(0)).current;
const translateY = useRef(new Animated.Value(0)).current;

const animateTranslate = () => {
  Animated.parallel([
    Animated.timing(translateX, {
      toValue: 100,
      duration: 500,
      useNativeDriver: true,
    }),
    Animated.timing(translateY, {
      toValue: 50,
      duration: 500,
      useNativeDriver: true,
    }),
  ]).start();
};

<Animated.View style={{ transform: [{ translateX }, { translateY }] }}>
  <Text>平移变换</Text>
</Animated.View>

核心要点：

  • 使用 translateX 和 translateY 实现平移
  • 支持正负值控制方向
  • 鸿蒙端平移变换正常

2. 缩放变换

实现缩放变换效果。

const scale = useRef(new Animated.Value(1)).current;

const animateScale = () => {
  Animated.spring(scale, {
    toValue: 1.5,
    friction: 3,
    tension: 40,
    useNativeDriver: true,
  }).start();
};

<Animated.View style={{ transform: [{ scale }] }}>
  <Text>缩放变换</Text>
</Animated.View>

核心要点：

  • 使用 scale 实现缩放
  • 支持大于1放大，小于1缩小
  • 鸿蒙端缩放变换正常

3. 旋转变换

实现旋转变换效果。

const rotate = useRef(new Animated.Value(0)).current;

const rotateValue = rotate.interpolate({
  inputRange: [0, 1],
  outputRange: ['0deg', '360deg'],
});

const animateRotate = () => {
  Animated.timing(rotate, {
    toValue: 1,
    duration: 1000,
    easing: Easing.linear,
    useNativeDriver: true,
  }).start();
};

<Animated.View style={{ transform: [{ rotate: rotateValue }] }}>
  <Text>旋转变换</Text>
</Animated.View>

核心要点：

  • 使用 rotate 实现旋转
  • 需要使用 interpolate 转换角度
  • 鸿蒙端旋转变换正常
