Summary: We had rendering support for prev links, but we never had any previous links in our metadata. Only next links. This adds that support to both Guides and APIs. **For guides**: `previous` is manually inserted into the metadata of the actual markdown file. **For APIs/Components**: `previous` is established via code within `extractDocs.js` > This isn't totally perfect. For example, the transition from the last guide to the first API/component has a next link from the guide, but not a previous link from the API since the way you get the previous links are different from guides and APIs. But this gets us really close. Closes https://github.com/facebook/react-native/pull/8754 Differential Revision: D3557972 Pulled By: hramos fbshipit-source-id: e270bb51e7a4f59f61dad28ae0928d27d0af3d4a

The [`ScrollView`](/react-native/docs/scrollview.html) 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.
|
|
|
|
```ReactNativeWebPlayer
|
|
import React, { Component } from 'react';
|
|
import{ AppRegistry, ScrollView, Image, Text, View } from 'react-native'
|
|
|
|
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')} />
|

<Text style={{fontSize:80}}>React Native</Text>
|
|
</ScrollView>
|
|
);
|
|
}
|
|
}
|
|
|
|
|
|
AppRegistry.registerComponent(
|
|
'IScrolledDownAndWhatHappenedNextShockedMe',
|
|
() => IScrolledDownAndWhatHappenedNextShockedMe);

`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 `ListView` instead. So let's [learn about the ListView](/react-native/docs/using-a-listview.html) next.
