8 | This component allows the user to swipe left and right through pages of data. Under the hood it is using the native [Android ViewPager](https://developer.android.com/reference/android/support/v4/view/ViewPager) and the [iOS UIPageViewController](https://developer.apple.com/documentation/uikit/uipageviewcontroller) implementations. [See it in action!](https://github.com/react-native-community/react-native-viewpager#preview)

28 | ## Linking
|
29 |
|
30 | ### >= 0.60
|
31 |
|
32 | Autolinking will just do the job.
|
33 |
|
34 | ### < 0.60
|
35 |
|
36 | #### Mostly automatic
|
37 |
|
38 | `react-native link @react-native-community/viewpager`
|
39 |
|
40 | #### Manual linking
|
41 |
|
42 | <details>
|
43 | <summary>Manually link the library on iOS</summary>
|
44 | </br>
|
45 |
|
46 | Follow the [instructions in the React Native documentation](https://facebook.github.io/react-native/docs/linking-libraries-ios#manual-linking) to manually link the framework or link using [Cocoapods](https://cocoapods.org) by adding this to your `Podfile`:
|
47 |
|
48 | ```ruby
|
49 | pod 'react-native-viewpager', :path => '../node_modules/@react-native-community/viewpager'
|
50 | ```
|
51 |
|
52 | </details>
|
53 |
|
54 | <details>
|
55 | <summary>Manually link the library on Android</summary>
|
56 | </br>
|
57 | Make the following changes:
|
58 |
|
59 | #### `android/settings.gradle`
|
60 |
|
61 | ```groovy
|
62 | include ':@react-native-community_viewpager'
|
63 | project(':@react-native-community_viewpager').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-community/viewpager/android')
|
64 | ```
|
65 |
|
66 | #### `android/app/build.gradle`
|
67 |
|
68 | ```groovy
|
69 | dependencies {
|
70 | ...
|
71 | implementation project(':@react-native-community_viewpager')
|
72 | }
|
73 | ```
|
74 |
|
75 | #### `android/app/src/main/.../MainApplication.java`
|
76 |
|
77 | On top, where imports are:
|
78 |
|
79 | ```java
|
80 | import com.reactnativecommunity.viewpager.RNCViewPagerPackage;
|
81 | ```
|
82 |
|
83 | Add the `RNCViewPagerPackage` class to your list of exported packages.
|
84 |
|
85 | ```java
|
86 | @Override
|
87 | protected List<ReactPackage> getPackages() {
|
88 | return Arrays.<ReactPackage>asList(
|
89 | new MainReactPackage(),
|
90 | new RNCViewPagerPackage()
|
91 | );
|
92 | }
|
93 | ```
|
94 |
|
95 | </details>
|
96 |
|
97 | ## Usage
|
98 |
|
99 | ```js
|
100 | import React from 'react';
|
101 | import {StyleSheet, View, Text} from 'react-native';
|
102 | import ViewPager from '@react-native-community/viewpager';
|
103 |
|
104 | const MyPager = () => {
|
105 | return (
|
106 | <ViewPager style={styles.viewPager} initialPage={0}>
|
107 | <View key="1">
|
108 | <Text>First page</Text>
|
109 | </View>
|
110 | <View key="2">
|
111 | <Text>Second page</Text>
|
112 | </View>
|
113 | </ViewPager>
|
114 | );
|
115 | };
|
116 |
|
117 | const styles = StyleSheet.create({
|
118 | viewPager: {
|
119 | flex: 1,
|
120 | },
|
121 | });
|
122 | ```
|
123 |
|
124 | **Attention:** Note that you can only use `View` components as children of `ViewPager` (cf. folder */example*)
|
125 | . For Android if `View` has own children, set prop `collapsable` to false <https://reactnative.dev/docs/view#collapsable>, otherwise react-native might remove those children views and and it's children will be rendered as separate pages
|
126 |
|
127 | ## Advanced usage
