Using a ScrollView

Using a ScrollView

The ScrollView is a generic scrolling container that can host multiple components and views. The scrollable items need not be homogenous, and you can scroll both vertically and horizontally (by setting the horizontal property).

This example creates a vertical ScrollView with both images and text mixed together.

import React, { Component } from 'react';
import { AppRegistry, ScrollView, Image, Text } from 'react-native'

export default class IScrolledDownAndWhatHappenedNextShockedMe extends Component {
  render() {
      return (
        <ScrollView>
          <Text style={{fontSize:96}}>Scroll me plz</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>If you like</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>Scrolling down</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>What's the best</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>Framework around?</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:80}}>React Native</Text>
        </ScrollView>
    );
  }
}

// skip these lines if using Create React Native App
AppRegistry.registerComponent(
  'IScrolledDownAndWhatHappenedNextShockedMe',
  () => IScrolledDownAndWhatHappenedNextShockedMe);

ScrollViews can be configured to allow paging through views using swiping gestures by using the pagingEnabled props. Swiping horizontally between views can also be implemented on Android using the ViewPagerAndroid component.

A ScrollView with a single item can be used to allow the user to zoom content. Set up the maximumZoomScale and minimumZoomScale props and your user will be able to use pinch and expand gestures to zoom in and out.

The ScrollView works best to present a small amount of things of a limited size. All the elements and views of a ScrollView are rendered, even if they are not currently shown on the screen. If you have a long list of more items that can fit on the screen, you should use a FlatList instead. So let's learn about list views next.
