This was very useful for us at the time, but my job hasn't involved working with react native for nearly six months now, so it's difficult for me to find the time to debug. I'll gladly merge and publish pull requests as quickly as possible, but I won't be actively fixing bugs or maintaining. My apologies and best wishes! 8 | 9 | ## Introduction 10 | 11 | This module implements a [higher-order component](https://gist.github.com/sebmarkbage/ef0bf1f338a7182b6775) that computes the current and total pages contained in a React Native [ScrollView](https://facebook.github.io/react-native/docs/scrollview.html) (or functionally similar) component. So it's really very simple. Seriously, when you get down to it it's like a division and a floor function. But it attempts to solve layout race conditions, re-layout and other subtleties. This component could trivially be used as a swiper alongside a page indicator but does not implement that itself. 12 | 13 | To be clear, this is strictly just a page-computing component. I assume you'll use it with [`pagingEnabled={true}`](https://facebook.github.io/react-native/docs/scrollview.html#pagingenabled), and it doesn't add paged scrolling for Android. 14 | 15 | ## Example 16 | 17 | ![PagedScrollViewExample](./example.gif) 18 | 19 | ```javascript 20 | import { ScrollView } from 'react-native' 21 | import AddPaging from 'react-native-paged-scroll-view' 22 | var PagedScrollView = AddPaging(ScrollView) 23 | 24 | ... 25 | handlePageChange (state) { 26 | console.log('current horizontal page:', state.currentHorizontalPage) 27 | console.log('current vertical page: ', state.currentVerticalPage) 28 | console.log('total horizontal pages: ', state.totalHorizontalPages) 29 | console.log('total vertical pages: ', state.totalVerticalPages) 30 | } 31 | 32 | render () { 33 | return ( 34 | 35 | ... 36 | 37 | ) 38 | } 39 | ... 40 | ``` 41 | 42 | ## Installation 43 | 44 | ```bash 45 | $ npm install react-native-paged-scroll-view 46 | ``` 47 | 48 | ## Usage 49 | 50 | ##### `require('react-native-paged-scroll-view')(Component, [scrollViewRefPropName="ref"])` 51 | Wrap either a `ScrollView` or a component functionally equivalent (implements `onScroll` and similar basic methods). Returns a higher order component with props passed through. 52 | 53 | **Arguments**: 54 | - `Component`: The component being wrapped. It must implement the basic methods of a ScrollView. 55 | - `scrollViewRefPropName`: the name of the property passed to `Component` that will return the ref. This exists in case you're using a wrapped a `ScrollView` component for which `ref` returns the ref of the wrapper instead of the ref of the `ScrollView`. If you provide this property, then your wrapped `ScrollView` should have a property `ref={this.props.} ` with your method name inserted. If you're just using a `ScrollView` though, you should be fine. Suggestions on how to improve this are welcome. 56 | 57 | **Props**: 58 | - `onPageChange`: `function(state)`: Executed on initial layout, when the page changes, or when the inner content changes. Callback is passed `state` object containing: 59 | - `totalHorizontalPages`: total number of horizontal pages, rounded to the nearest integer. 60 | - `totalVerticalPages`: total number of vertical pages, rounded to the nearest integer. 61 | - `currentHorizontalPage`: the current horizontal page, rounded to the nearest integer. 62 | - `currentVerticalPage`: the current vertical page, rounded to the nearest integer. 63 | - `onInitialization`: `function(ref)`: Executed once, when the component is initially mounted and only once the dimensions have been measured. Useful, for example, for scrolling to a specific page once the component is mounted. 64 | 65 | **Attributes**: 66 | - `ref.scrollX`: current horizontal scroll offset 67 | - `ref.scrollY`: current vertical scroll offset 68 | - `ref.state.currentHorizontalPage`: as defined above 69 | - `ref.state.currentVerticalPage`: as defined above 70 | - `ref.state.totalHorizontalPages`: as defined above 71 | - `ref.state.totalVerticalPages`: as defined above 72 | 73 | **Methods**: 74 | - `ref.scrollToPage(horizontal, vertical, animated)`: Scroll to a specific page 75 | 76 | # License 77 | (c) 2015 Ricky Reusser.
