React Native如何从子组件向父组件传递文本输入值

import React, { useState } from 'react';

const ParentComponent = () => {
  const [inputValue, setInputValue] = useState('');

  // 处理文本输入变化的回调函数
  const handleInputChange = (text) => {
    setInputValue(text);
  };

  return (
    <ChildComponent inputValue={inputValue} onInputChange={handleInputChange} />
  );
};

import React from 'react';
import { TextInput } from 'react-native';

const ChildComponent = ({ inputValue, onInputChange }) => {
  return (
    <TextInput
      value={inputValue}
      onChangeText={onInputChange}
      placeholder="请输入文本"
    />
  );
};
