当按下FlatList项时移动到另一个屏幕，现在我在pressHandler()中打印键值。

import React from 'react';
import { View, FlatList, TouchableOpacity, Text } from 'react-native';
import { useNavigation } from '@react-navigation/native';

const data = [
  { id: 1, title: 'Item 1' },
  { id: 2, title: 'Item 2' },
  { id: 3, title: 'Item 3' },
];

const MyScreen = () => {
  const navigation = useNavigation();

  const pressHandler = (itemId) => {
    console.log('Pressed item ID:', itemId);
    // 导航到另一个屏幕
    navigation.navigate('AnotherScreen', { itemId });
  };

  const renderItem = ({ item }) => (
    <TouchableOpacity onPress={() => pressHandler(item.id)}>
      <Text>{item.title}</Text>
    </TouchableOpacity>
  );

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

export default MyScreen;
