This topic is about React Native – ScrollView. In this chapter, we will show you how to work with the ScrollView element.
We will again create ScrollViewExample.js and import it in Home.
App.js
import React from 'react';
import ScrollViewExample from './scroll_view.js';
const App = () => {
return (
<ScrollViewExample />
)
}export default App
Scrollview will render a list of names. We will create it in state.
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'
}
})
When we run the app, we will see the scrollable list of names.
