Examples

Simple example (iOS and android is slightly different), see in Difference section.


import React, {Component} from 'react';
import {
  StyleSheet,
  Text,
  View,
  AppRegistry,
} from 'react-native';
import Carousel from 'react-native-carousel-view';

export default class example extends Component {
  render() {
    return (
      <View style={{
        flex: 1,
        justifyContent: 'center',
        alignItems: 'center',
      }}>
        <View style={styles.container}>
          <Carousel
            width={375}
            height={300}
            delay={2000}
            indicatorAtBottom={false}
            indicatorSize={20}
            indicatorText="✽"
            indicatorColor="red"
            >
            <View style={styles.contentContainer}>
              <Text>Page 1</Text>
            </View>
            <View style={styles.contentContainer}>
              <Text>Page 2</Text>
            </View>
            <View style={styles.contentContainer}>
              <Text>Page 3</Text>
            </View>
          </Carousel>
        </View>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 0.5,
    justifyContent: 'center',
    alignItems: 'center',
  },
  contentContainer: {
    borderWidth: 2,
    borderColor: '#CCC',
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

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

Difference

In Android the carousel effect use ViewPagerAndroid, on the other hand, in iOS use ScrollView. Due to the mechanism difference between iOS and Android so the styles settings is slightly different.

The contentContainerStyle props should be set in different settings if you want to have the same appearance in iOS and Android.

In iOS contentContainerStyle means the container of the child. This is an example.

<Carousel
  width={375}
  height={300} // =====> the container will be height 300
  >
  <View style={{height: 200, width: 300}}> // ===> child height 200, width 300. if the children's height and width is not set width and height from Carousel component will set to children.
    <Text>Page 1</Text>
  </View>
  <View style={{height: 200, width: 300}}> // ===> child height 200, width 300
    <Text>Page 2</Text>
  </View>
  <View style={{height: 200, width: 300}}> // ===> child height 200, width 300
    <Text>Page 3</Text>
  </View>
</Carousel>

but in Android it means it is the children's view style. According to the react-native docs https://facebook.github.io/react-native/docs/viewpagerandroid.html

Container that allows to flip left and right between child views. Each child view of the ViewPagerAndroid will be treated as a separate page and will be stretched to fill the ViewPagerAndroid. It is important all children are s and not composite components. You can set style properties like padding or backgroundColor for each child.

<Carousel
  width={375}
  height={300} // =====> the container will be height 300
  >
  <View style={{height: 200}}> // ===> child height will still be 300, and width will automatically be 375 and can't be changed
    <Text>Page 1</Text>
  </View>
  <View style={{height: 200}}> // ===> child height will still be 300, and width will automatically be 375 and can't be changed
    <Text>Page 2</Text>
  </View>
  <View style={{height: 200}}> // ===> child height will still be 300, and width will automatically be 375 and can't be changed
    <Text>Page 3</Text>
  </View>
</Carousel>
