Full-Screen Background Image
While developing an App we usually need a Full-Screen Background Image, especially while making a Splash / Introductory Screen. So here is the Example of React Native Full Screen Background Image.
To make a full-screen background we are using ImageBackground component provided by React Native.
To Import Image Background in Code
import { ImageBackground } from 'react-native'
Render Using
1. Static Image Resources
<ImageBackground
source={require('./your-img.png')}
style={{width: 400, height: 400}}
/>
require
can also be used for including audio, video or document files in your project. Most common .mp3, .wav, .mp4, .mov, .html and .pdf.
2. Network Requests for Images
<ImageBackground
source={{uri: 'https://raw.githubusercontent.com/AboutReact/sampleresource/master/sample_img.png'}}
style={{width: 400, height: 400}}
/>
3. Uri Data Images
<ImageBackground
style={{width: 66, height: 58}}
source={{
uri:'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg=='
}}

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.
Code for Full Screen Background Image
Open App.js in any code editor and replace the code with the following code
App.js
// React Native Full Screen Background Image
// https://aboutreact.com/react-native-full-screen-background-image/
// import React in our code
import React from 'react';
// import all the components we are going to use
import {
SafeAreaView,
View,
Text,
ImageBackground,
StyleSheet,
Image,
} from 'react-native';
const App = () => {
return (
<SafeAreaView style={styles.container}>
<ImageBackground
style={{flex: 1}}
//We are using online image to set background
source={{
uri:
'https://raw.githubusercontent.com/AboutReact/sampleresource/master/crystal_background.jpg',
}}
//You can also set image from your project folder
//require('./images/background_image.jpg')
>
<View style={styles.container}>
<Text style={styles.titleStyle}>
Example of React Native Swipe Button
</Text>
<View style={styles.centerContentStyle}>
<Image
source={{
uri:
'https://raw.githubusercontent.com/AboutReact/sampleresource/master/logosmalltransparen.png',
}}
style={{
width: 40,
height: 40,
marginTop: 90
}}
/>
<Text style={styles.TextStyle}>
AboutReact
</Text>
</View>
</View>
</ImageBackground>
</SafeAreaView>
);
};
export default App;
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 10,
},
titleStyle: {
fontSize: 28,
fontWeight: 'bold',
textAlign: 'center',
padding: 10,
},
centerContentStyle: {
justifyContent: 'center',
alignItems: 'center',
},
});
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
