class Example extends Component {
  onSkipBtnHandle = (index) => {
    Alert.alert('Skip');
    console.log(index);

    const pageArray = [{
      title: 'Page 1',
      description: 'Description 1',
      img: 'https://goo.gl/Bnc3XP',
      imgStyle: {
        height: 80 * 2.5,
        width: 109 * 2.5,
      },
      backgroundColor: '#fa931d',
      fontColor: '#fff',
      level: 10,
    }, {
      title: 'Page 2',
      description: 'Description 2',
      img: require('../assets/some_image.png'),
      imgStyle: {
        height: 93 * 2.5,
        width: 103 * 2.5,

      backgroundColor: '#a4b602',
      fontColor: '#fff',
      level: 10,
    }];
    return (
      <AppIntro
        onNextBtnClick={this.nextBtnHandle}
        onDoneBtnClick={this.doneBtnHandle}
        onSkipBtnClick={this.onSkipBtnHandle}
        onSlideChange={this.onSlideChangeHandle}
        pageArray={pageArray}
      />
    );
  }
}

AppRegistry.registerComponent('Example', () => Example);

Advanced Usage

If you need customized page like my Example, you can pass in View component into AppIntro component and set level. Remember any need use parallax effect component, Need to be <View level={10}></View> inside.

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
} from 'react-native';
import AppIntro from 'react-native-app-intro';

const styles = StyleSheet.create({
  slide: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#9DD6EB',
    padding: 15,
  },
  text: {
    color: '#fff',
    fontSize: 30,
    fontWeight: 'bold',
  },
});

class Example extends Component {

  render() {
    return (
      <AppIntro>
        <View style={[styles.slide,{ backgroundColor: '#fa931d' }]}>
          <View level={10}><Text style={styles.text}>Page 1</Text></View>
          <View level={15}><Text style={styles.text}>Page 1</Text></View>
          <View level={8}><Text style={styles.text}>Page 1</Text></View>
        </View>
        <View style={[styles.slide, { backgroundColor: '#a4b602' }]}>
          <View level={-10}><Text style={styles.text}>Page 2</Text></View>
          <View level={5}><Text style={styles.text}>Page 2</Text></View>
          <View level={20}><Text style={styles.text}>Page 2</Text></View>
        </View>
        <View style={[styles.slide,{ backgroundColor: '#fa931d' }]}>
          <View level={8}><Text style={styles.text}>Page 3</Text></View>
          <View level={0}><Text style={styles.text}>Page 3</Text></View>
          <View level={-10}><Text style={styles.text}>Page 3</Text></View>
        </View>
        <View style={[styles.slide, { backgroundColor: '#a4b602' }]}>
          <View level={5}><Text style={styles.text}>Page 4</Text></View>
          <View level={10}><Text style={styles.text}>Page 4</Text></View>
          <View level={15}><Text style={styles.text}>Page 4</Text></View>
        </View>
      </AppIntro>
    );
  }
}
AppRegistry.registerComponent('Example', () => Example);

And in Android, image inside view component, view need width、height.
<View style={{
  position: 'absolute',
  top: 80,
  left: 30,
  width: windows.width,
  height: windows.height,
}} level={20}
>
  <Image style={{ width: 115, height: 70 }} source={require('./img/1/c2.png')} />
</View>
