A pull-to-refresh ListView which shows a loading spinner while your data reloads
In action (from ReactNativeHackerNews):
var React = require('react-native') var {Text, View, ListView} = React var RefreshableListView = require('react-native-refreshable-listview') var ArticleStore = require('../stores/ArticleStore') var StoreWatchMixin = require('./StoreWatchMixin') var ArticleView = require('./ArticleView') var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2}) // assumes immutable objects var ArticlesScreen = React.createClass({ mixins: [StoreWatchMixin], getInitialState() { return {dataSource: ds.cloneWithRows(ArticleStore.all())} }, getStoreWatches() { this.watchStore(ArticleStore, () => { this.setState({dataSource: ds.cloneWithRows(ArticleStore.all())}) }) }, reloadArticles() { return ArticleStore.reload() // returns a Promise of reload completion }, renderArticle(article) { return <ArticleView article={article} /> }, render() { return ( <RefreshableListView dataSource={this.state.dataSource} renderRow={this.renderArticle} loadData={this.reloadArticles} refreshDescription="Refreshing articles" /> ) } })Replace a ListView with a RefreshableListView to add pulldown-to-refresh functionality. Accepts the same props as ListView (except renderHeader, see below), with a few extras.
loadData: func.isRequiredA function returning a Promise or taking a callback, invoked upon pulldown. The refreshing indicator (spinner) will show until the Promise resolves or the callback is called.refreshDescription: oneOfType([string, element])Text/element to show alongside spinner. If a customrefreshingIndictatorComponentis used this value will be passed as itsdescriptionprop.refreshingIndictatorComponent: oneOfType([func, element])Content to show in list header when refreshing. Can be a component class or instantiated element. Defaults toRefreshableListView.RefreshingIndicator. You can easily customise the appearance of the indicator by passing in a customised<RefreshableListView.RefreshingIndicator />, or provide your own entirely custom content to be displayed.minDisplayTime: numberMinimum time the spinner will show for.minBetweenTime: numberMinimum time after a refresh before another refresh can be performed.minPulldownDistance: numberMinimum distance (in px) which the list has to be scrolled off the top to trigger a refresh.ignoreInertialScroll: boolRequire the user to be actually touching the screen when the pulldown distance exceedsminPulldownDistanceto trigger a refresh (eg. not just inertially scrolling off the top). Defaults totrue.onScroll: funcAn event handler for theonScrollevent which will be chained after the one defined by theRefreshableListView.renderHeaderWrapper: funcA function to render content in the header, which will always be rendered (regardless of 'refreshing' status). IMPORTANT: The first argument passed to this function is the refresh indicator. You must render this within your custom header for the spinner to appear. See the example.renderHeader: funcDeprecated - userenderHeaderWrapperinstead.scrollEventThrottle: numberHow oftenListViewproduces scroll events, in ms. Defaults to a fairly low value, try setting it higher if you encounter performance issues. Keep in mind that a higher value will make the pulldown-to-refresh behaviour less responsive.
Component with activity indicator to be displayed in list header when refreshing.
description: oneOfType([string, element])Text/element to show alongside spinner.stylesheet: objectA stylesheet object which overrides one or more of the styles defined in the RefreshingIndicator stylesheet.activityIndicatorComponent: oneOfType([func, element])The spinner to display. Defaults to<ActivityIndicatorIOS />.
Low level component used by RefreshableListView. Use this directly if you want to manually control the refreshing status (rather than using a Promise).

Alias of ListView.DataSource, for convenience.
var indicatorStylesheet = StyleSheet.create({ wrapper: { backgroundColor: 'red', height: 60, marginTop: 10, }, content: { backgroundColor: 'blue', marginTop: 10, height: 60, }, }) <RefreshableListView refreshingIndictatorComponent={ <RefreshableListView.RefreshingIndicator stylesheet={indicatorStylesheet} /> } />var MyRefreshingIndicator = React.createClass({ render() { return ( <View> <MySpinner /> <Text>{this.props.description}</Text> </View> ) }, }) <RefreshableListView refreshingIndictatorComponent={MyRefreshingIndicator} /> // or <RefreshableListView refreshingIndictatorComponent={<MyRefreshingIndicator />} />- 1.2.0
- deprecated
renderHeaderin favour ofrenderHeaderWrapperas some developers seemed to be confused by the fact that arenderHeaderhandler for a standardListViewwill not automatically just work with this component, but rather needs to be modified as described in the documentation. The new proprenderHeaderWrapperworks identically to the previous one, however hopefully now it is named differently it will be more apparent that its behaviour is not the same as withListView. TherenderHeaderprop will be removed in 2.0.
- deprecated
- 1.1.0
- added behaviour to ignore inertial scrolling (@dhrrgn)
- exposed props: ignoreInertialScroll, scrollEventThrottle
- 1.0.0
- Split RefreshableListView into 3 parts:
- RefreshableListView handles 'refreshing' state by invoking 'loadData' callback and waiting for resolution.
- ControlledRefreshableListView handles rendering of ListView header, depending on isRefreshing prop. Calls onRefresh handler when pulldown-to-refresh scroll motion occurs.
- RefreshingIndicator is the component rendered in the header of the ListView when refreshing. Pass in a customised version of this (or a completely different component) to RefreshableListView or ControlledRefreshableListView if you want to customise refresh indicator appearance.
- Added Jest unit tests
- Split RefreshableListView into 3 parts:
- 0.3.0 added minPulldownTime & minBetweenTime props, fixed bug where refresh could happen twice
- 0.2.0 added support for ListView props setNativeProps and getScrollResponder (@almost & @sscotth)
