React Native Full Screen Background Image

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

//This is an example code to set Backgroud image///
import React from 'react';
//import react in our code. 
import { View, Text, ImageBackground, StyleSheet, Image } from 'react-native';
//import all the components we are going to use. 

export default class App extends React.Component {
  render() {
    return (
      <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.MainContainer}>
          <Image
            source={{
              uri:
                'https://raw.githubusercontent.com/AboutReact/sampleresource/master/logosmalltransparen.png',
            }}
            style={{ width: 40, height: 40, marginTop: 90 }}
          />
          <Text style={styles.TextStyle}>https://aboutreact.com</Text>
        </View>
      </ImageBackground>
    );
  }
}
const styles = StyleSheet.create({
  MainContainer: {
    flex: 1,
    alignItems: 'center',
  },
  TextStyle: {
    color: '#0250a3',
    textAlign: 'center',
    fontSize: 30,
    marginTop: 10,
  },
});

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).
