Example of Collapsible / Accordion / Expandable List View in React Native

Introduction

This is an Example of Collapsible / Accordion / Expandable List View in React Native. To make a Collapsible / Accordion / Expandable View we will use react-native-collapsible library.

As a mobile application developer, we always have a limited area to draw our imagination and in some cases, we have lots of data to show. To solve this issue we have a view called Collapsible View which shows the important data on the top and if the user is interested in the content they can click to expand the view and can see the related data in detail.

This example will have Single Collapsible View, Selectors, and Accordion View.

For those who have heard Accordion for the first time; Accordion is frequently used in HTML which is like expandable list in mobile development.

Collapsible

{/*Code for Single Collapsible Start*/}
<TouchableOpacity onPress={this.toggleExpanded}>
<View style={styles.header}>
  <Text style={styles.headerText}>Single Collapsible</Text>
  {/*Heading of Single Collapsible*/}
</View>
</TouchableOpacity>
{/*Content of Single Collapsible*/}
<Collapsible collapsed={this.state.collapsed} align="center">
<View style={styles.content}>
  <Text style={{ textAlign: 'center' }}>
    This is a dummy text of Single Collapsible View
  </Text>
</View>
</Collapsible>
{/*Code for Single Collapsible Ends*/}

Accordion

<Accordion
  activeSections={activeSections}
  // For any default active section
  sections={CONTENT}
  // Title and content of accordion
  touchableComponent={TouchableOpacity}
  // Which type of touchable component you want
  // It can be the following Touchables
  // TouchableHighlight, TouchableNativeFeedback
  // TouchableOpacity , TouchableWithoutFeedback
  expandMultiple={multipleSelect}
  // Do you want to expand mutiple at a time or single at a time
  renderHeader={this.renderHeader}
  // Header Component(View) to render
  renderContent={this.renderContent}
  // Content Component(View) to render
  duration={400}
  // Duration for Collapse and expand
  onChange={setSections}
  // Setting the state of active sections
/>

In this example, you will see

  1. Simple collapsible View.
  2. Accordion View (With Multiple/Single Expand).
  3. Selector Bar connects with Accordion View.

So Let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependencies

To use Collapsible and Accordion component you need to install react-native-collapsible and react-native-collapsible/Accordion package.

To install this open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-collapsible --save
npm install react-native-collapsible/Accordion --save

We will use some animation to expand the view, for that you need to install react-native-animatable package.

To use Animatable component install using

npm install react-native-animatable --save

These commands will copy all the dependencies into your node_module directory.

Code for Collapsible – Accordion – Expandable View

Now Open App.js in any code editor and replace the code with the following code

App.js

// Example of Collapsible/Accordion/Expandable List View in React Native
// https://aboutreact.com/collapsible-accordion-expandable-view/

// import React in our code
import React, {useState} from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  Switch,
  ScrollView,
  StyleSheet,
  Text,
  View,
  TouchableOpacity,
} from 'react-native';

// import for the animation of Collapse and Expand
import * as Animatable from 'react-native-animatable';

// import for the collapsible/Expandable view
import Collapsible from 'react-native-collapsible';

// import for the Accordion view
import Accordion from 'react-native-collapsible/Accordion';

// Dummy content to show
// You can also use dynamic data by calling web service
const CONTENT = [
  {
    title: 'Terms and Conditions',
    content:
      'The following terms and conditions, together
       with any referenced documents form a legal 
       agreement between you and your employer, employees,
       agents, contractors and any other entity on whose 
       behalf you accept these terms',
  },
  {
    title: 'Privacy Policy',
    content:
      'A Privacy Policy agreement is the agreement where you
       specify if you collect personal data from your users,
       what kind of personal data you collect and what you do
       with that data.',
  },
  {
    title: 'Return Policy',
    content:
      'Our Return & Refund Policy template lets you get 
       started with a Return and Refund Policy agreement. 
       This template is free to download and use. According to
       TrueShip study, over 60% of customers review a Return/Refund
       Policy before they make a purchasing decision.',
  },
];

//To make the selector (Something like tabs)
const SELECTORS = [
  {title: 'T&C', value: 0},
  {title: 'Privacy Policy', value: 1},
  {title: 'Return Policy', value: 2},
  {title: 'Reset all'},
];

const App = () => {
  // Default active selector
  const [activeSections, setActiveSections] = useState([]);
  // Collapsed condition for the single collapsible
  const [collapsed, setCollapsed] = useState(true);
  // MultipleSelect is for the Multiple Expand allowed
  // True: Expand multiple at a time
  // False: One can be expand at a time
  const [multipleSelect, setMultipleSelect] = useState(false);

  const toggleExpanded = () => {
    // Toggling the state of single Collapsible
    setCollapsed(!collapsed);
  };

  const setSections = (sections) => {
    // Setting up a active section state
    setActiveSections(
      sections.includes(undefined) ? [] : sections
    );
  };

  const renderHeader = (section, _, isActive) => {
    // Accordion header view
    return (
      <Animatable.View
        duration={400}
        style={[
          styles.header,
          isActive ? styles.active : styles.inactive
        ]}
        transition="backgroundColor">
        <Text style={styles.headerText}>
          {section.title}
        </Text>
      </Animatable.View>
    );
  };

  const renderContent = (section, _, isActive) => {
    // Accordion Content view
    return (
      <Animatable.View
        duration={400}
        style={[
          styles.content,
          isActive ? styles.active : styles.inactive
        ]}
        transition="backgroundColor">
        <Animatable.Text
          animation={isActive ? 'bounceIn' : undefined}
          style={{textAlign: 'center'}}>

        </Animatable.Text>
      </Animatable.View>
    );
  };

  return (

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

To run the project on an Android Virtual Device or on real debugging device

react-native run-android

or on the iOS Simulator by running (macOS only)

react-native run-ios
