如何在react native中从扁平列表中选择特定项目？

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

const data = [
  { id: 1, name: '项目1' },
  { id: 2, name: '项目2' },
  { id: 3, name: '项目3' },
  // 其他项目...
];

const App = () => {
  const [selectedItem, setSelectedItem] = useState(null);

  const renderItem = ({ item }) => (
    <TouchableOpacity
      onPress={() => setSelectedItem(item)}
      style={{
        backgroundColor: selectedItem === item ? 'gray' : 'white',
        padding: 10,
        marginVertical: 5,
      }}
    >
      <Text>{item.name}</Text>
    </TouchableOpacity>
  );

  return (
    <View>
      <FlatList
        data={data}
        renderItem={renderItem}
        keyExtractor={(item) => item.id.toString()}
      />
      {selectedItem && (
        <Text>已选择项目：{selectedItem.name}</Text>
      )}
    </View>
  );
};

export default App;
