react-native-pager-view ViewPager

npm package Lean Core Extracted License

Lint iOS Build Android Build

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!


ViewPager


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

Getting started

yarn add react-native-pager-view

New architecture setup (Fabric)

This library supports new architecture! We have two example folders one for each architecture. If you are using this library in your own project there some extra steps needed.

iOS

Install pods with this flag inside ios folder:

RCT_NEW_ARCH_ENABLED=1 bundle exec pod install

(Inside of fabricexample the RCT_NEW_ARCH_ENABLED is already set to true by default inside Podfile)

Android

Set newArchEnabled to true inside android/gradle.properties (this flag is already set to true in fabricexample) and then run:

yarn android

If you have issues with running android build you can try to generate codegen before the build using this command:

cd android && ./gradlew generateCodegenArtifactsFromSchema

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

For advanced usage please take a look into our example project

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: 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}/>
