Я работаю над учебником по React-Native. Когда я пытался создать экземпляр ScrollView внутри моего приложения, он не работает. Нет ошибок, нет красного экрана, он просто не будет прокручиваться мимо второго из пяти элементов.React Native ScrollView не работает в iOS
Вот код для моего index.ios.js
//imports a library
import React from 'react';
import { AppRegistry, View } from 'react-native';
import Header from './src/Components/Header';
import AlbumList from './src/Components/AlbumList';
// import AlbumDetail from './src/Components/AlbumDetail';
//create Component
const App =() => {
return (
<View style={{ flex: 1 }}>
<Header headerText={'Albums'} />
<AlbumList />
</View>
);
};
//renders component
AppRegistry.registerComponent('albums',() => App);
Вот код для компонента AlbumList
import React, { Component } from 'react';
import { ScrollView } from 'react-native';
//axios was npm installed it is a tool for HTPPRequests
import axios from 'axios';
//importing component to use inside of class component
import AlbumDetail from './AlbumDetail';
//This makes a class component which can handle data
class AlbumList extends Component {
//sets state to an object with a key value pair
state = { albums: [] };
//when the page loads the HTTPrequest is done asynch
componentWillMount() {
axios.get('https://rallycoding.herokuapp.com/api/music_albums')
.then(response => this.setState({ albums: response.data }));
}
//this grabs the info coming in from the HTTPRequest and puts it into a component
renderAlbums() {
return this.state.albums.map(album =>
//album= is setting the prop for the component, it is not necessary to name it album
<AlbumDetail key={album.title} album={album} />);
}
//renders the class component
render() {
return (
<ScrollView>
{ this.renderAlbums() }
</ScrollView>
);
}
}
И, наконец, вот код компонента AlbumDetail.
import React from 'react';
import { Text, View, Image } from 'react-native';
import Card from './Card';
import CardSection from './CardSection';
//We setup the prop being passed into this compnent in the AlbumList component
//{this will grab our prop "album" and then accesses the title key's value}
const AlbumDetail = ({ album }) => {
const { title, artist, thumbnail_image, image } = album;
return (
<Card>
<CardSection>
<View style={styles.thumbnailContainterStyle}>
<Image
style={styles.thumbnailStyle}
source={{ uri: thumbnail_image }}
/>
</View>
<View style={styles.headerContentStyles}>
<Text style={styles.headerTextStyle}>{title}</Text>
<Text>{artist}</Text>
</View>
</CardSection>
<CardSection>
<Image
style={styles.imageStyle}
source={{ uri: image }}
/>
</CardSection>
</Card>
);
};
const styles = {
headerContentStyles: {
flexDirection: 'column',
justifyContent: 'space-around'
},
headerTextStyle: {
fontSize: 18
},
thumbnailStyle: {
height: 50,
width: 50
},
thumbnailContainterStyle: {
justifyContent: 'center',
alignItems: 'center',
marginLeft: 10,
marginRight: 10
},
imageStyle: {
height: 300,
flex: 1,
width: null
}
};
export default AlbumDetail;
Любая помощь была бы принята с благодарностью.
Обертывание детей с 'TouchableWithoutFeedback' сделал трюк для меня, спасибо! :) – epegzz
