How to Implement Radio Button In React Native ?
Last Updated :
10 May, 2025
In this article, we will learn to implement a Radio Button in React Native. A radio button signifies a graphical user interface element enabling individuals to make an exclusive selection among multiple alternatives.
React Native is a popular platform for creating native mobile apps for iOS and Android using a single codebase. To use it, configure the development setup, install Node.js, and use Expo CLI. This versatile framework accelerates app development, allowing developers to create immersive, high-performing applications.
Prerequisites:
Step-by-Step Implementation
Step 1: Create a React Native Project
Now, create a project with the following command.
npx create-expo-app app-name --template
Note: Replace the app-name with your app name for example : react-native-demo-app
Next, you might be asked to choose a template. Select one based on your preference as shown in the image below. I am selecting the blank template because it will generate a minimal app, as clean as an empty canvas in JavaScript.
It completes the project creation and displays a message: "Your Project is ready!" as shown in the image below.
Now go into your project folder, i.e., react-native-demo
cd app-name
Project Structure:
Step 2: Run Application
Start the server by using the following command.
npx expo start
Then, the application will display a QR code.
- For the Android users,
- For the Android Emulator, press "a" as mentioned in the image below.
- For Physical Device, Download the "Expo Go" app from the Play Store. Open the app, and you will see a button labeled "Scan QR Code." Click that button and scan the QR code; it will automatically build the Android app on your device.
- For iOS users, simply scan the QR code using the Camera app.
- If you're using a web browser, it will provide a local host link that you can use as mentioned in the image below.
Step 3: Start Coding
Example 1: In this example, we are going to use the React Native Paper library to create the radio button in react native.
- Import libraries: Import required libraries at the top of the file.
JavaScript
// Importing necessary libraries
import React, { useState } from 'react';
// Importing necessary components from React and React Native
import { View, Text, StyleSheet } from 'react-native';
// Importing RadioButton from react-native-paper
import { RadioButton } from 'react-native-paper';
- StyleSheet: Create a StyleSheet to style components like container, radioGroup, radioButton, and radioLabel.
JavaScript
// Define styles for the components
const styles = StyleSheet.create({
container: {
flex: 1, // Take up the full screen
backgroundColor: '#F5F5F5', // Light gray background
justifyContent: 'center', // Center content vertically
alignItems: 'center', // Center content horizontally
},
radioGroup: {
flexDirection: 'row', // Arrange radio buttons in a row
alignItems: 'center', // Align items vertically in the center
justifyContent: 'space-around', // Space out radio buttons evenly
marginTop: 20, // Add margin at the top
borderRadius: 8, // Rounded corners
backgroundColor: 'white', // White background for the group
padding: 16, // Padding inside the group
elevation: 4, // Shadow for Android
shadowColor: '#000', // Shadow color for iOS
shadowOffset: {
width: 0,
height: 2, // Shadow offset for iOS
},
shadowOpacity: 0.25, // Shadow opacity for iOS
shadowRadius: 3.84, // Shadow radius for iOS
},
radioButton: {
flexDirection: 'row', // Arrange radio button and label in a row
alignItems: 'center', // Align items vertically in the center
},
radioLabel: {
marginLeft: 8, // Space between radio button and label
fontSize: 16, // Font size for the label
color: '#333', // Dark gray color for the label
},
});
- RadioButton.Android and Text: RadioButton.Android is used to create a radio button in android and Text is to display the text beside it, i.e View component like a row.
JavaScript
<View style={styles.radioGroup}>
{/* First radio button for ReactJS */}
<View style={styles.radioButton}>
<RadioButton.Android
value="option1"
status={selectedValue === 'option1' ? 'checked' : 'unchecked'}
onPress={() => setSelectedValue('option1')}
color="#007BFF" // Custom color for the radio button
/>
<Text style={styles.radioLabel}>
ReactJS
</Text>
</View>
{/* Second radio button for NextJs */}
<View style={styles.radioButton}>
<RadioButton.Android
value="option2"
status={selectedValue === 'option2' ? 'checked' : 'unchecked'}
onPress={() => setSelectedValue('option2')}
color="#007BFF" // Custom color for the radio button
/>
<Text style={styles.radioLabel}>
NextJs
</Text>
</View>
{/* Third radio button for React Native */}
<View style={styles.radioButton}>
<RadioButton.Android
value="option3"
status={selectedValue === 'option3' ? 'checked' : 'unchecked'}
onPress={() => setSelectedValue('option3')}
color="#007BFF" // Custom color for the radio button
/>
<Text style={styles.radioLabel}>
React Native
</Text>
</View>
</View>
- useState: Used to maintain the state, i.e, selectedValue and set the default value to 'option1'.
JavaScript
const [selectedValue, setSelectedValue] = useState('option1');
- App Component: Wrap the all RadioButton.Android and Text with a View and return that inside the App function to render and place the useState inside the App function, also make sure to export the App.
JavaScript
// Define the main App component
export default function App() {
// Used to maintain the state i.e, selectedValue and set the default value to 'option1'
const [selectedValue, setSelectedValue] = useState('option1');
return (
<View style={styles.container}>
{/* Radio button group container */}
<View style={styles.radioGroup}>
{/* First radio button for ReactJS */}
<View style={styles.radioButton}>
<RadioButton.Android
value="option1"
status={selectedValue === 'option1' ? 'checked' : 'unchecked'}
onPress={() => setSelectedValue('option1')}
color="#007BFF" // Custom color for the radio button
/>
<Text style={styles.radioLabel}>
ReactJS
</Text>
</View>
{/* Second radio button for NextJs */}
<View style={styles.radioButton}>
<RadioButton.Android
value="option2"
status={selectedValue === 'option2' ? 'checked' : 'unchecked'}
onPress={() => setSelectedValue('option2')}
color="#007BFF" // Custom color for the radio button
/>
<Text style={styles.radioLabel}>
NextJs
</Text>
</View>
{/* Third radio button for React Native */}
<View style={styles.radioButton}>
<RadioButton.Android
value="option3"
status={selectedValue === 'option3' ? 'checked' : 'unchecked'}
onPress={() => setSelectedValue('option3')}
color="#007BFF" // Custom color for the radio button
/>
<Text style={styles.radioLabel}>
React Native
</Text>
</View>
</View>
</View>
);
}

App.js:
JavaScript
// App.js
import React, { useState } from 'react';
import { View, Text, StyleSheet } from 'react-native';
import { RadioButton } from 'react-native-paper';
const styles = StyleSheet.create({
container: {
flex: 1,

</View>
);
};
export default App;
Output
Example 2: Upon selection of an option, the background color changes to a vibrant blue while ensuring optimal text contrast for improved visibility.
- Import libraries: Import required libraries at the top of the file.
JavaScript
// Import necessary libraries and components
import React, { useState } from 'react';
import {
View, // Main container for the app
Text, // Text component for displaying text
TouchableOpacity, // Touchable component for handling touch events
StyleSheet // Stylesheet for styling components
} from 'react-native';
- StyleSheet: Create a StyleSheet to style components like a container, a radioButton, and radioButtonText.
JavaScript
// Styles for the components
const styles = StyleSheet.create({
container: {
flex: 1, // Take up the full screen
justifyContent: 'center', // Center content vertically
alignItems: 'center', // Center content horizontally
backgroundColor: '#F5F5F5', // Light gray background
},
radioButton: {
paddingVertical: 12, // Vertical padding
paddingHorizontal: 16, // Horizontal padding
borderRadius: 8, // Rounded corners
marginVertical: 8, // Vertical margin between buttons
borderWidth: 1, // Border width
borderColor: '#007BFF', // Border color
flexDirection: 'row', // Arrange children in a row
alignItems: 'center', // Align items vertically in the center
justifyContent: 'space-between', // Space out children evenly
width: 280, // Fixed width for the button
},
radioButtonText: {
fontSize: 16, // Font size for the text
},
});
- CustomRadioButton: Create a "CustomRadioButton" to display a button with a label and change its style based on selection.
JavaScript
// CustomRadioButton component: A reusable radio button component
const CustomRadioButton = ({ label, selected, onSelect }) => (
<TouchableOpacity
style={[
styles.radioButton,
{ backgroundColor: selected ? '#007BFF' : '#FFF' } // Change background color based on selection
]}
onPress={onSelect} // Trigger onSelect callback when pressed
>
<Text
style={[
styles.radioButtonText,
{ color: selected ? '#FFF' : '#000' } // Change text color based on selection
]}
>
{label} {/* Display the label text */}
</Text>
</TouchableOpacity>
);
- useState: It is used to manage the state i.e, selectedValue value and set the default value of selectedValue to null.
JavaScript
const [selectedValue, setSelectedValue] = useState(null);
- App Component: Wrap the CustomRadioButton with a View and return that inside the App function to render and place the useState inside the App function, also make sure to export the App.
JavaScript
// Main App component
const App = () => {
// used to manage the state i.e, selectedValue value and set the default value of selectedValue to null
const [selectedValue, setSelectedValue] = useState(null);
return (
<View style={styles.container}>
{/* Render three CustomRadioButton components with different labels */}
<CustomRadioButton
label="ReactJS" // Label for the first option
selected={selectedValue === 'option1'} // Check if this option is selected
onSelect={() => setSelectedValue('option1')} // Update state when selected
/>
<CustomRadioButton
label="NextJS" // Label for the second option
selected={selectedValue === 'option2'} // Check if this option is selected
onSelect={() => setSelectedValue('option2')} // Update state when selected
/>
<CustomRadioButton
