react-native-viewpager

This is the ViewPager componnent in React Native both for Android and iOS. This is a JavaScript-only implementation of pager for React Native. Like ListView, this can render hundreds of pages without performance issue. Better than the one in Android, this ViewPager can auto play -- turn page automaticly, loop -- make infinite scrolling.

Demo

Demo project is here.

Usage

1. Run npm install react-native-viewpager --save
2. Code like this:

var ViewPager = require('react-native-viewpager');
<ViewPager
    dataSource={this.state.dataSource}
    renderPage={this._renderPage}/>

More configuration

• dataSource: this is require to provide pages data,
• renderPage: this is require to render page view,
• autoPlay: true to turn page automatically,
• initialPage: to set the index of the first page to load,
• isLoop: true to run in infinite scroll mode,
• locked: true to disable touch scroll,
• onChangePage: page change callback,
• renderPageIndicator: render custom ViewPager indicator.
• initialPage: show initially some other page than first page.

New configuration props

• type: horizontal type of scrolling. options are horizontal and vertical.
• indicatorsStyle: To set custom style on Indicators.
• containerViewStyle: To set custom style on containerView.
• pagerHeight: To set Height of pages. default is equal to screen height of device.
• gestureDistanceThreshold: to set distance of gesture, default is 0.5.

Page Transition Animation Controls

• animation: function that returns a React Native Animated configuration.

Example:

var ViewPager = require('react-native-viewpager');
<ViewPager
    dataSource={this.state.dataSource}
    renderPage={this._renderPage}
    animation = {(animatedValue, toValue, gestureState) => {
    // Use the horizontal velocity of the swipe gesture
    // to affect the length of the transition so the faster you swipe
    // the faster the pages will transition
    var velocity = Math.abs(gestureState.vx);
    var baseDuration = 300;
    var duration = (velocity > 1) ? 1/velocity * baseDuration : baseDuration;

    return Animated.timing(animatedValue,
    {
      toValue: toValue,
      duration: duration,
      easing: Easing.out(Easing.exp)
    });
  }}
/>
