如何使用React Native绘制动画

import React, { Component } from 'react';
import { View, Animated } from 'react-native';

class AnimatedExample extends Component {
  constructor(props) {
    super(props);
    this.animatedValue = new Animated.Value(0);
  }

  componentDidMount() {
    this.startAnimation();
  }

  startAnimation() {
    Animated.timing(this.animatedValue, {
      toValue: 1,
      duration: 1000,
      useNativeDriver: true, // 使用原生驱动器以提高性能
    }).start();
  }

  render() {
    const opacity = this.animatedValue.interpolate({
      inputRange: [0, 1],
      outputRange: [0, 1],
    });

    return (
      <View style={{ flex: 1 }}>
        <Animated.View style={{ opacity }}>
          {/* 在这里放置要动画的内容 */}
        </Animated.View>
      </View>
    );
  }
}

export default AnimatedExample;

<Animated.View style={{ opacity }}>
  {/* 在这里放置要动画的内容 */}
</Animated.View>

componentDidMount() {
  this.startAnimation();
}
