如何在React-Native中从firebase返回子对象数组

import React, { useEffect, useState } from 'react';
import firebase from 'firebase';

const YourComponent = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    // 连接到Firebase数据库
    const firebaseConfig = {
      // Firebase配置信息
    };
    if (!firebase.apps.length) {
      firebase.initializeApp(firebaseConfig);
    }

    // 获取数据库实例
    const database = firebase.database();

    // 查询子对象数组
    const ref = database.ref('users');

    // 监听数据变化
    ref.on('value', (snapshot) => {
      // 获取子对象数组的值
      const dataArray = snapshot.val();

      // 更新状态
      setData(dataArray);
    });

    // 清除监听器
    return () => {
      ref.off();
    };
  }, []);

  return (
    <div>
      {data.map((item) => (
        <div key={item.id}>
          <p>Name: {item.name}</p>
          <p>Age: {item.age}</p>
        </div>
      ))}
    </div>
  );
};

export default YourComponent;
