A simple and fully customizable React Native component that implements an Image Slider UI.

Package Exports

  • @navid73/react-native-image-slider

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@navid73/react-native-image-slider) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

   |

| firstItem | number | default is 0 , index of image to display when slider box loads |

1- add below import in your code :

import { SliderBox } from "react-native-image-slider-box";

2- Define your image array source, for below examples i create array in state.

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      images: [
        "https://source.unsplash.com/1024x768/?nature",
        "https://source.unsplash.com/1024x768/?water",
        "https://source.unsplash.com/1024x768/?girl",
        "https://source.unsplash.com/1024x768/?tree", // Network image
        require('./assets/images/girl.jpg'),          // Local image
      ]
    };
  }
  // other component code ...
}

3- Use SliderBox such as these below examples :

Example 1 : SliderBox without and handler or customization

<SliderBox images={this.state.images} />

Example 2 : SliderBox with image press handler and currentImageEmitter

SliderBox

<SliderBox
  images={this.state.images}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  currentImageEmitter={index => console.warn(`current pos is: ${index}`)}
/>

Example 3 : SliderBox with image press handler and change slider height (default is 200)

SliderBox

<SliderBox
  images={this.state.images}
  sliderBoxHeight={400}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
/>

Example 4 : SliderBox with custom width from parent. use onLayout function by calling it from root View of component.

onLayout = e => {
  this.setState({
    width: e.nativeEvent.layout.width
  });
};
render() {
    return (
        <View style={styles.container} onLayout={this.onLayout}>
            <SliderBox
                images={this.state.images}
                sliderBoxHeight={200}
                onCurrentImagePressed={index =>
                    console.warn(`image ${index} pressed`)
                }
                parentWidth={this.state.width}
            />
        </View>
    );
  }

Example 5 : SliderBox with custom dots color

SliderBox

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
/>

Example 6 : SliderBox with custom dot style

SliderBox

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
  dotStyle={{
    width: 15,
    height: 15,
    borderRadius: 15,
    marginHorizontal: 10,
    padding: 0,
    margin: 0
  }}
/>

Example 7 : SliderBox with change paging box padding (Vertical height from bottom of SliderBox) + add autoplay and circleLoop attribute for jump to the first image after swipe the last one.

SliderBox

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
  paginationBoxVerticalPadding={20}
  autoplay
  circleLoop
/>

Example 8 : use Custom Image Component, customize pagination, image modes and dotStyles:

SliderBox

<SliderBox
  ImageComponent={FastImage}
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
  paginationBoxVerticalPadding={20}
  autoplay
  circleLoop
  resizeMethod={'resize'}
  resizeMode={'cover'}
  paginationBoxStyle={{
    position: "absolute",
    bottom: 0,
    padding: 0,
    alignItems: "center",
    alignSelf: "center",
    justifyContent: "center",
    paddingVertical: 10
  }}
  dotStyle={{
    width: 10,
    height: 10,
    borderRadius: 5,
    marginHorizontal: 0,
    padding: 0,
    margin: 0,
    backgroundColor: "rgba(128, 128, 128, 0.92)"
  }}
  ImageComponentStyle={{borderRadius: 15, width: '97%', marginTop: 5}}
  imageLoadingColor="#2196F3"
/>

Example 9 : SliderBox with activeOpacity:

SliderBox

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  activeOpacity={0.5}
/>

Full-Component(Screen) Example:

import React, { Component } from "react";
import { StyleSheet, Text, View } from "react-native";

import { SliderBox } from "react-native-image-slider-box";

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      images: [
        "https://source.unsplash.com/1024x768/?nature",
        "https://source.unsplash.com/1024x768/?water",
        "https://source.unsplash.com/1024x768/?girl",
        "https://source.unsplash.com/1024x768/?tree",
        require('./assets/images/girl.jpg'),
      ]
    };
  }

  render() {
    return (
      <View style={styles.container}>
        <SliderBox
          images={this.state.images}
          onCurrentImagePressed={index =>
            console.warn(`image ${index} pressed`)
          }
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1
  }
});
