Next version
Lazy page loading has been added to the next
version. If you would like to test lazy apporach in your app, you can try next version using below command:
yarn add react-native-pager-view@next
Migration
"@react-native-community/viewpager"
library has been changed to react-native-pager-view
. Here you can find more information, how to migrate pager view to the latest version
Getting started
yarn add react-native-pager-view
Linking
>= 0.60
Autolinking will just do the job.
< 0.60
Mostly automatic
react-native link react-native-pager-view
Manual linking
Follow the instructions in the React Native documentation to manually link the framework or link using Cocoapods by adding this to your Podfile
:
pod 'react-native-pager-view', :path => '../node_modules/react-native-pager-view'
android/settings.gradle
include ':react-native-pager-view'
project(':react-native-pager-view').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-pager-view/android')
android/app/build.gradle
dependencies {
...
implementation project(':react-native-pager-view')
}
android/app/src/main/.../MainApplication.java
On top, where imports are:
Add import com.reactnativepagerview.PagerViewPackage;
Add the PagerViewPackage
class to your list of exported packages.
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new PagerViewPackage()
);
}
Usage
import React from 'react';
import { StyleSheet, View, Text } from 'react-native';
import PagerView from 'react-native-pager-view';
const MyPager = () => {
return (
<PagerView style={styles.pagerView} initialPage={0}>
<View key="1">
<Text>First page</Text>
</View>
<View key="2">
<Text>Second page</Text>
</View>
</PagerView>
);
};
const styles = StyleSheet.create({
pagerView: {
flex: 1,
},
});
Attention: Note that you can only use View
components as children of PagerView
(cf. folder /example)
. For Android if View
has own children, set prop collapsable
to false https://reactnative.dev/docs/view#collapsable-android, otherwise react-native might remove those children views and and it's children will be rendered as separate pages

API
| Prop | Description | Platform |
| -------------------------------------------------------------------- | :-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | :------: |
| initialPage
| Index of initial page that should be selected | both |
| scrollEnabled: boolean
| Should pager view scroll, when scroll enabled | both |
| onPageScroll: (e: PageScrollEvent) => void
| Executed when transitioning between pages (ether because the animation for the requested page has changed or when the user is swiping/dragging between pages) | both |
| onPageScrollStateChanged: (e: PageScrollStateChangedEvent) => void
| Function called when the page scrolling state has changed | both |
| onPageSelected: (e: PageSelectedEvent) => void
| This callback will be called once the ViewPager finishes navigating to the selected page | both |
| pageMargin: number
| Blank space to be shown between pages | both |
| keyboardDismissMode: ('none' / 'on-drag')
| Determines whether the keyboard gets dismissed in response to a drag | both |
| orientation: Orientation
| Set horizontal
or vertical
scrolling orientation (it does not work dynamically) | both |
| transitionStyle: TransitionStyle
| Use scroll
or curl
to change transition style (it does not work dynamically) | iOS |
| showPageIndicator: boolean
| Shows the dots indicator at the bottom of the view | iOS |
| overScrollMode: OverScollMode
| Used to override default value of overScroll mode. Can be auto
, always
or never
. Defaults to auto
| Android |
| offscreenPageLimit: number
| Set the number of pages that should be retained to either side of the currently visible page(s). Pages beyond this limit will be recreated from the adapter when needed. Defaults to RecyclerView's caching strategy. The given value must either be larger than 0. | Android |
| overdrag: boolean
| Allows for overscrolling after reaching the end or very beginning or pages. Defaults to false
| iOS |
| layoutDirection: ('ltr' / 'rtl' / 'locale')

| Method | Description | Platform |
| ------------------------------------------ | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | :------: |
| setPage(index: number)
| Function to scroll to a specific page in the PagerView. Invalid index is ignored. | both |
| setPageWithoutAnimation(index: number)
| Function to scroll to a specific page in the PagerView. Invalid index is ignored. | both |
| setScrollEnabled(scrollEnabled: boolean)
| A helper function to enable/disable scroll imperatively. The recommended way is using the scrollEnabled prop, however, there might be a case where a imperative solution is more useful (e.g. for not blocking an animation) | both |

Reanimated onPageScroll handler
An example can be found here
Instructions
To attach reanimated handler with onPageScroll
follow the below steps.
// 1. Define the handler
function usePageScrollHandler(handlers, dependencies) {
const {context, doDependenciesDiffer} = useHandler(handlers, dependencies);
const subscribeForEvents = ['onPageScroll'];
return useEvent(
event => {
'worklet';
const {onPageScroll} = handlers;
if (onPageScroll && event.eventName.endsWith('onPageScroll')) {
onPageScroll(event, context);
}
},
subscribeForEvents,
doDependenciesDiffer,
);
}
// 2. Attach the event handler
import { PagerView } from "react-native-pager-view";
import Animated from "react-native-reanimated";
const AnimatedPagerView = Animated.createAnimatedComponent(PagerView);
const pageScrollHandler = usePageScrollHandler({
onPageScroll: e => {
'worklet';
offset.value = e.offset;
console.log(e.offset, e.position);
},
});
<AnimatedPagerView onPageScroll={pageScrollHandler}/>
