当我相应地在react native中滚动时，需要突出显示菜单

import React from 'react';
import { FlatList, Text, View } from 'react-native';

const menuData = [
  { id: 1, title: '菜单项1' },
  { id: 2, title: '菜单项2' },
  { id: 3, title: '菜单项3' },
  // 其他菜单项...
];

const App = () => {
  const renderItem = ({ item }) => (
    <View style={{ padding: 10 }}>
      <Text>{item.title}</Text>
    </View>
  );

  return (
    <FlatList
      data={menuData}
      renderItem={renderItem}
      keyExtractor={(item) => item.id.toString()}
    />
  );
};

export default App;

import React, { useState } from 'react';
import { FlatList, Text, View } from 'react-native';

const menuData = [
  { id: 1, title: '菜单项1' },
  { id: 2, title: '菜单项2' },
  { id: 3, title: '菜单项3' },
  // 其他菜单项...
];

const App = () => {
  const [highlightedItem, setHighlightedItem] = useState(null);

  const renderItem = ({ item }) => (
    <View style={{ padding: 10, backgroundColor: item.id === highlightedItem ? 'yellow' : 'white' }}>
      <Text>{item.title}</Text>
    </View>
  );

  const handleScroll = (event) => {
    const offsetY = event.nativeEvent.contentOffset.y;
    const index = Math.floor(offsetY / 50); // 假设每个菜单项的高度为50

    setHighlightedItem(menuData[index].id);
  };

  return (
    <FlatList
      data={menuData}
      renderItem={renderItem}
      keyExtractor={(item) => item.id.toString()}
      onScroll={handleScroll}
    />
  );
};

export default App;
