React Native Tree View for Android and IOS devices

React Native Tree View for Android and IOS devices

This is an Example to create a React Native Tree View using react-native-final-tree-view for Android and IOS devices. A Tree View is simple a hierarchical view which is used to show the parent-child relationship between the data. You can simply understand the Tree View using the following image. In the below image the yellow ball is the parent and green ones are the children of the yellow ball. Please remember tree structure has no child limit so green children can also have the child and there can be more child under them.

In this example, we will see how to create a TreeView in React Native. So let’s get started.

We are going to use TreeView component from  react-native-final-tree-view library.

Import TreeView using

To Show TreeView

For this example, we are going to use dummy data array to make a screen with 2 parents having multiple child hierarchy under them.

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

Installation of Dependency

To use TreeView we need to install react-native-final-tree-view dependency.

To install this open the terminal and jump into your project using

Run the following command to install

This command will copy all the dependency into your node_module directory.

–save is optional, it is just to update the react-native-final-tree-view dependency in your package.json file.

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

App.js

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).
