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 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.

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}>
            React Native Full Screen Background Image
          </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

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
