Configuring buttons

Button example gif

import React from 'react';
import { Ionicons } from '@expo/vector-icons';
import { StyleSheet, View } from 'react-native';
import AppIntroSlider from 'react-native-app-intro-slider';

const styles = StyleSheet.create({
  buttonCircle: {
    width: 40,
    height: 40,
    backgroundColor: 'rgba(0, 0, 0, .2)',
    borderRadius: 20,
    justifyContent: 'center',
    alignItems: 'center',
  },
  image: {
    width: 320,
    height: 320,
  }
});

// slides = [...]

export default class App extends React.Component {
  _renderNextButton = () => {
    return (
      <View style={styles.buttonCircle}>
        <Ionicons
          name="md-arrow-round-forward"
          color="rgba(255, 255, 255, .9)"
          size={24}
          style={{ backgroundColor: 'transparent' }}
        />
      </View>
    );
  }
  _renderDoneButton = () => {
    return (
      <View style={styles.buttonCircle}>
        <Ionicons
          name="md-checkmark"
          color="rgba(255, 255, 255, .9)"
          size={24}
          style={{ backgroundColor: 'transparent' }}
        />
      </View>
    );
  }
  render() {
    return (
      <AppIntroSlider
        slides={slides}
        renderDoneButton={this._renderDoneButton}
        renderNextButton={this._renderNextButton}
      />
    );
  }
}

Custom slide layout

Custom layout example gif

import React from 'react';
import { Ionicons } from '@expo/vector-icons';
import { StyleSheet, View, Text, Image } from 'react-native';
import { LinearGradient } from 'expo';
import AppIntroSlider from 'react-native-app-intro-slider';

const styles = StyleSheet.create({
  mainContent: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'space-around',
  },
  image: {
    width: 320,
    height: 320,
  },
  text: {
    color: 'rgba(255, 255, 255, 0.8)',
    backgroundColor: 'transparent',
    textAlign: 'center',
    paddingHorizontal: 16,
  },
  title: {
    fontSize: 22,
    color: 'white',
    backgroundColor: 'transparent',
    textAlign: 'center',
    marginBottom: 16,
  }
});

const slides = [
  {
    key: 'somethun',
    title: 'Quick setup, good defaults',
    text: 'React-native-app-intro-slider is easy to setup with a small footprint and no dependencies. And it comes with good default layouts!',
    icon: 'ios-images-outline',
    colors: ['#63E2FF', '#B066FE'],
  },
  {
    key: 'somethun1',
    title: 'Super customizable',
    text: 'The component is also super customizable, so you can adapt it to cover your needs and wants.',
    icon: 'ios-options-outline',
    colors: ['#A3A1FF', '#3A3897'],
  },
  {
    key: 'somethun2',
    title: 'No need to buy me beer',
    text: 'Usage is all free',
    icon: 'ios-beer-outline',
    colors: ['#29ABE2', '#4F00BC'],
  },
];

export default class App extends React.Component {
  _renderItem = props => (
    <LinearGradient
      style={[styles.mainContent, {
        paddingTop: props.topSpacer,
        paddingBottom: props.bottomSpacer,
        width: props.width,
        height: props.height,
      }]}
      colors={props.colors}
      start={{x: 0, y: .1}} end={{x: .1, y: 1}}
    >
      <Ionicons style={{ backgroundColor: 'transparent' }} name={props.icon} size={200} color="white" />
      <View>
        <Text style={styles.title}>{props.title}</Text>
        <Text style={styles.text}>{props.text}</Text>
      </View>
    </LinearGradient>
  );

  render() {
    return (
      <AppIntroSlider
        slides={slides}
        renderItem={this._renderItem}
        bottomButton
      />
    );
  }
}

Here a custom renderItem is supplied and the bottomButton-props has been set to true. Notice how the setup of slides has been configured to support icons and gradient backgrounds.

renderItem function renders DefaultSlide Function returning a slide. The function is passed the slide object as wells as { topSpacer: Number, bottomSpacer: Number }. These show the "safe-space" where other UI is not interfering - take a look at DefaultSlide.js too see how they are set up.

Configure behavior

showSkipButton boolean false Enable to show a skip button to the left of pagination dots. When bottomButton == true the skip button is a small text under the full-width next button

onDone function void Called when user ends the introduction by pressing the done button
onSkip function void Called when user presses the skip button

slide object

Each slide object should contain at least a unique key. If you use the default layouts your object should furthermore contain:

Name Type Note
title string The title
titleStyle Style-prop Styling for the title (e.g color, fontSize)
text string Main text of slide
textStyle Style-prop Styling for the text (e.g color, fontSize)
image Image-source prop Slide image

backgroundColor string Slide background color

If you use a custom renderItem-method you can design your slide objects as you see fit.
