水平ScrollView不能在React Native中滚动

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

const HorizontalScrollViewExample = () => {
  return (
    <ScrollView horizontal={true} contentContainerStyle={styles.container}>
      <View style={styles.item}>
        <Text>Item 1</Text>
      </View>
      <View style={styles.item}>
        <Text>Item 2</Text>
      </View>
      <View style={styles.item}>
        <Text>Item 3</Text>
      </View>
      <View style={styles.item}>
        <Text>Item 4</Text>
      </View>
      <View style={styles.item}>
        <Text>Item 5</Text>
      </View>
    </ScrollView>
  );
};

const styles = StyleSheet.create({
  container: {
    flexDirection: 'row',
  },
  item: {
    width: 200,
    height: 200,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: 'lightblue',
    margin: 10,
  },
});

export default HorizontalScrollViewExample;
