React Native - 滚动视图
在本章中,我们将演示如何使用ScrollView元素。
我们将再次创建ScrollViewExample.js并将其导入Home中。
App.js
import React from 'react'; import ScrollViewExample from './scroll_view.js'; const App = () => { return ( <ScrollViewExample /> ) }export default App
滚动视图将呈现一个姓名列表。我们将在状态中创建它。
ScrollView.js
import React, { Component } from 'react'; import { Text, Image, View, StyleSheet, ScrollView } from 'react-native'; class ScrollViewExample extends Component { state = { names: [ {'name': 'Ben', 'id': 1}, {'name': 'Susan', 'id': 2}, {'name': 'Robert', 'id': 3}, {'name': 'Mary', 'id': 4}, {'name': 'Daniel', 'id': 5}, {'name': 'Laura', 'id': 6}, {'name': 'John', 'id': 7}, {'name': 'Debra', 'id': 8}, {'name': 'Aron', 'id': 9}, {'name': 'Ann', 'id': 10}, {'name': 'Steve', 'id': 11}, {'name': 'Olivia', 'id': 12} ] } render() { return ( <View> <ScrollView> { this.state.names.map((item, index) => ( <View key = {item.id} style = {styles.item}> <Text>{item.name}</Text> </View> )) } </ScrollView> </View> ) } } export default ScrollViewExample const styles = StyleSheet.create ({ item: { flexDirection: 'row', justifyContent: 'space-between', alignItems: 'center', padding: 30, margin: 2, borderColor: '#2a4944', borderWidth: 1, backgroundColor: '#d2f7f1' } })
当我们运行应用程序时,我们将看到可滚动的姓名列表。
