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 and above
iOS	iOS support
ViewPager1	ViewPager2

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

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

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
overScrollMode: OverScrollMode	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} />;

usePagerView Hook Usage

The usePagerView hook is a convenient way to manage the state and control the behavior of the <PagerView /> component. It provides functions and variables to interact with the pager, such as navigating between pages and enabling/disabling scrolling.

Below is an example of how to use the usePager hook:

export function PagerHookExample() {
  const { AnimatedPagerView, ref, ...rest } = usePagerView({ pagesAmount: 10 });
  
  return (
    <SafeAreaView style={styles.container}>
      <AnimatedPagerView
        testID="pager-view"
        ref={ref}
        style={styles.PagerView}
        initialPage={0}
        layoutDirection="ltr"
        overdrag={rest.overdragEnabled}
        scrollEnabled={rest.scrollEnabled}
        onPageScroll={rest.onPageScroll}
        onPageSelected={rest.onPageSelected}
        onPageScrollStateChanged={rest.onPageScrollStateChanged}
        pageMargin={10}
        orientation="horizontal"
      >
        {useMemo(
          () =>
            rest.pages.map((_, index) => (
              <View
                testID="pager-view-content"
                key={index}
                style={{
                  flex: 1,
                  backgroundColor: '#fdc08e',
                  alignItems: 'center',
                  padding: 20,
                }}
                collapsable={false}
              >
                <LikeCount />
                <Text testID={`pageNumber${index}`}>
                  {`page number ${index}`}
                </Text>
              </View>
            )),
          [rest.pages]
        )}
      </AnimatedPagerView>
      <NavigationPanel {...rest} />
    </SafeAreaView>
  );
}

How the Example Works:

• Pager View Setup: The AnimatedPagerView component wraps PagerView in React Native's animation capabilities. It accepts multiple props from the usePager hook, such as overdragEnabled, scrollEnabled, onPageScroll, onPageSelected, and others to manage pager behavior.

• Rendering Pages: The pages are dynamically generated using the rest.pages array (initialized by usePager). The useMemo hook ensures the pages are only recomputed when necessary for performance reasons.

Conclusion

The usePager hook makes it easy to handle pagination with dynamic views. This example demonstrates how to set up a simple paginated interface where users can scroll through pages, interact with page elements, and control the pager with external navigation.
