如何在滚动视图滚动时检查视图可滚动位置

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

const MyScrollView = () => {
  const [isEndReached, setIsEndReached] = useState(false);

  const handleScroll = (event) => {
    const { layoutMeasurement, contentSize, contentOffset } = event.nativeEvent;

    // 判断滚动位置是否达到底部
    if (layoutMeasurement.height + contentOffset.y >= contentSize.height) {
      setIsEndReached(true);
    } else {
      setIsEndReached(false);
    }
  };

  return (
    <ScrollView onScroll={handleScroll}>
      <View>
        {/* 视图内容 */}
      </View>
      {isEndReached && (
        <View>
          <Text>已达到底部</Text>
        </View>
      )}
    </ScrollView>
  );
};

export default MyScrollView;
