InfiniteScrollView

InfiniteScrollView is a React Native scroll view that notifies you as the scroll offset approaches the bottom. You can instruct it to display a loading indicator while you load more content. This is a common design in feeds. InfiniteScrollView also supports horizontal scroll views.

It conforms to ScrollableMixin so you can compose it with other scrollable components.

Installation

Make sure you have react-native 0.8.0-rc.

npm install react-native-infinite-scroll-view

Usage

Compose InfiniteScrollView with the scrollable component that you would like to get events from. In the case of a ListView, you would write:

var React = require('react-native');
var InfiniteScrollView = require('react-native-infinite-scroll-view');
var {
  ListView,
} = React;

// Inside of a component's render() method:
render() {
  return (
    <ListView
      renderScrollComponent={props => <InfiniteScrollView {...props} />}
      dataSource={...}
      renderRow={...}
      canLoadMore={this.state.canLoadMoreContent}
      isLoadingMore={this.state.isLoadingContent}
    />
  );
}

Tips and Caveats

• Horizontal scroll views are supported
• When you load more content in an infinite ListView, the ListView by default will render only one row per frame. This means that for a short amount of time after loading new content, the user could still be very close to the bottom of the scroll view and may trigger a second load.

Implementation

InfiniteScrollView uses the onScroll event to continuously calculate how far the scroll offset is from the bottom.
