1.项目地址

https://github.com/race604/react-native-viewpager

2.Usage

1. Runnpm 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,monospace; padding:0.2em 0px; margin:0px">autoPlay:trueto turn page automatically,monospace; padding:0.2em 0px; margin:0px">isLoop:trueto run in infinite scroll mode,monospace; padding:0.2em 0px; margin:0px">locked:trueto disable touch scroll,monospace; padding:0.2em 0px; margin:0px">onChangePage: page change callback,monospace; padding:0.2em 0px; margin:0px">renderPageIndicator: render custom ViewPager indicator.

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) }); }} />
