react-native-pager-view

This component allows the user to swipe left and right through pages of data. Under the hood it is using the native Android ViewPager and the iOS UIPageViewController implementations. See it in action!

Versions

4.x	5.x
iOS	iOS support
ViewPager1	ViewPager2

New architecture support (Fabric)

This library supports both architectures (Paper and Fabric). If you would like enable new architecture, please run below command:

yarn add react-native-pager-view@newarch

Migration

In version 6.x support for transitionStyle property has been dropped. More information here.

"@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

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

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

Manually link the library on iOS

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'

Manually link the library on Android

Make the following changes:

`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 its children will be rendered as separate pages

Advanced usage

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
`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')`	Specifies layout direction. Use `ltr` or `rtl` to set explicitly or `locale` to deduce from the default language script of a locale. Defaults to `locale`	both

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

Known Issues

flex:1 does not work for child views, please use width: '100%', height: '100%' instead
[iOS]: In case of UIViewControllerHierarchyInconsistency error, please use below fix:

requestAnimationFrame(() => refPagerView.current?.setPage(index));

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}/>
