Example of Expandable List View in React Native

Example of Expandable List View in React Native

This is an Example of Expandable List View in React Native. To make an Expandable List View we will create an Expandable Component with the help of stylesheet.

Expandable list view is like a sectioned list view but with hidden section content. The heading of the list will always be visible and after clicking the heading you will see the subheading of the list view.

In this example, we will make the Expandable ListView which is similar to an accordion view.

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

In this example, we will create an expandable component called ExpandableItemComponent in which will be used as a single expandable item and will take the value dynamically using the prop. In our Main App class, according to the data, we will add this expandable component to a scroll view by passing the data with the help a loop.

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.

Now jump into the project directory using

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

App.js (For Multiple Expand at a Time)

App.js (For Single Expand at a Time)

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
react-native run-ios (macOS only).

  1. Hi,
    I have used this ExpandableListView to display the items in a cart. Parent is just a text and the child component contains, no of quantity and the increment, decrement buttons. Now the problem is, I can’t update the subcategory values when a increment or decrement is clicked. pls provide me a solution to do this.

  2. Hi, I really like this expandable list. However, I want to change the alert into a Modal. I am using react-native-modal library. It is not working… When I press the item (cat 22 for example) from the expandable list, the modal doesn’t show. Only when I press the item again, it shows. Do u have a solution for this? Thanks in advance.
