我尝试使用react-native-image-header-scroll-view,它总是显示相同的问题“元素类型无效:需要字符串(对于内置组件)或类/函数(对于复合组件),但得到:您可能忘记了从定义组件的文件中导出组件,或者您可能混淆了默认导入和命名导入"。我试着降级版本,但仍然不起作用。

import React from 'react';
import {
  View,
  Text,
  Image,
  StyleSheet,
  Dimensions,
  StatusBar,
  Platform,
} from 'react-native';
import { HeaderImageScrollView, TriggeringView } from 'react-native-image-header-scroll-view';

const MIN_HEIGHT = Platform.OS === 'ios' ? 90 : 55;
const MAX_HEIGHT = 350;

const CardItemDetails = ({route}) => {
  const itemData = route.params.itemData;

  return (
    <View style={styles.container}>
      <HeaderImageScrollView  maxHeight={MAX_HEIGHT} minHeight={MIN_HEIGHT} renderHeader={() => (<Image source={itemData.image} style={styles.image} />)}>
        <TriggeringView>
          <View>
            <Text style={styles.title}>Overview</Text>
          </View>
        </TriggeringView>
      </HeaderImageScrollView>
    </View>
  );
};

export default CardItemDetails;

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  image: {
    height: MAX_HEIGHT,
    width: Dimensions.get('window').width,
    alignSelf: 'stretch',
    resizeMode: 'cover',
  },
  title: {
    fontSize: 20,
  },
  name: {
    fontWeight: 'bold',
  },
  section: {
    padding: 20,
    borderBottomWidth: 1,
    borderBottomColor: '#cccccc',
    backgroundColor: 'white',
  },
  sectionTitle: {
    fontSize: 18,
    fontWeight: 'bold',
  },
  sectionContent: {
    fontSize: 16,
    textAlign: 'justify',
  },
  categories: {
    flexDirection: 'row',
    justifyContent: 'flex-start',
    alignItems: 'flex-start',
    flexWrap: 'wrap',
  },
  categoryContainer: {
    flexDirection: 'row',
    backgroundColor: '#FF6347',
    borderRadius: 20,
    margin: 10,
    padding: 10,
    paddingHorizontal: 15,
  },
  category: {
    fontSize: 14,
    color: '#fff',
    marginLeft: 10,
  },
  titleContainer: {
    flex: 1,
    alignSelf: 'stretch',
    justifyContent: 'center',
    alignItems: 'center',
  },
  imageTitle: {
    color: 'white',
    backgroundColor: 'transparent',
    fontSize: 24,
  },
  navTitleView: {
    height: MIN_HEIGHT,
    justifyContent: 'center',
    alignItems: 'center',
    paddingTop: Platform.OS === 'ios' ? 40 : 5,
    opacity: 0,
  },
  navTitle: {
    color: 'white',
    fontSize: 18,
    backgroundColor: 'transparent',
  },
  sectionLarge: {
    minHeight: 300,
  },
});

我找到解决你问题的方法了。我可以在node_modules > react-native-image-header-scroll-view > lib中看到,但我没有找到HeaderImageScrollView文件。
因此,您可以替换ImageHeaderScrollView而不是HeaderImageScrollView。
以下是示例:

<View style={styles.container}>
      <ImageHeaderScrollView  maxHeight={MAX_HEIGHT} minHeight={MIN_HEIGHT} renderHeader={() => (<Image source={itemData.image} style={styles.image} />)}>
        <TriggeringView>
          <View>
            <Text style={styles.title}>Overview</Text>
          </View>
        </TriggeringView>
      </ImageHeaderScrollView>
    </View>

上面的例子解决了你的问题。

对于最近也面临这个问题的人来说,解决方案是更新库

npm update react-native-image-header-scroll-view

还确保进口如下

import ImageHeaderScrollView, { TriggeringView } from 'react-native-image-header-scroll-view';
