Expandable Circular Button in React Native using react-native-circle-button

Expandable Circular Button

This is an example of an Expandable Circular Button in React Native using react-native-circle-button. One of our AboutReact family members needed a button that can expand so the user can see more options which is why I have planned this post to share with others also. This button will help you to hide infrequent options from the screen and will show the options only when the user wants to see them.

To Make Expandable Circular Button

<CircleButton
  size={45}
  primaryColor="#41727E"
  secondaryColor="#459186"
  onPressButtonTop={() => alert('Top Button Clicked')}
  onPressButtonRight={() => alert('Right Button Clicked')}
  onPressButtonBottom={() => alert('Bottom Button Clicked')}
  onPressButtonLeft={() => alert('Left Button Clicked')}
/>

In this example, we will make a circular button using react-native-circle-button library. Initially, the button will be with add sign only and on the press of the button, the circle button will expand and will show more options to choose from. On click of options, we will show an alert.

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 command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

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

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

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

Installation of Dependency

To use CircleButton we need to install react-native-circle-button dependency.

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

cd ProjectName

Run the following command to install

npm install react-native-circle-button --save

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

Code

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

App.js

// Expandable Circular Button in React Native using react-native-circle-button
// https://aboutreact.com/react-native-expandable-circular-button/

// import React in our code
import React from 'react';

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

//Import basic react native elements
import CircleButton from 'react-native-circle-button';

const App = () => {
  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleStyle}>

        <CircleButton
          size={45}
          primaryColor="#41727E"
          secondaryColor="#459186"
          onPressButtonTop={
            () => alert('Top Button Clicked')
          }
          onPressButtonRight={
            () => alert('Right Button Clicked')
          }
          onPressButtonBottom={
            () => alert('Bottom Button Clicked')
          }
          onPressButtonLeft={
            () => alert('Left Button Clicked')
          }
        />
      </View>
    </SafeAreaView>
  );
};
export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    padding: 10,
  },
  titleStyle: {
    fontSize: 28,
    fontWeight: 'bold',
    textAlign: 'center',
    padding: 10,
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

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

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
