React Native 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
1 | import { ImageBackground } from 'react-native' |
Render Using
1. Static Image Resources
1 2 3 4 | <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
1 2 3 4 | <ImageBackground source={{uri: 'http://aboutreact.com/wp-content/uploads/2018/07/sample_img.png'}} style={{width: 400, height: 400}} /> |
3. Uri Data Images
1 2 3 4 5 6 | <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
Run the following commands to create a new React Native projectnpm install -g react-native-cli
This will make a project structure with an index file named App.js in your project directory.react-native init ProjectName
Open App.js in any code editor and replace the code with the following code.
App.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 | //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: 'http://aboutreact.com/wp-content/uploads/2018/08/8f17765c523f5b75f3dc60ae145e9df7.jpg', }} //You can also set image from your project folder //require('./images/background_image.jpg') // > <View style={styles.MainContainer}> <Image source={{ uri: 'http://aboutreact.com/wp-content/uploads/2018/07/logosmalltransparen.png', }} style={{ width: 40, height: 40, marginTop: 90 }} /> <Text style={styles.TextStyle}>http://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 ProjectNamereact-native run-androidreact-native run-ios (macOS only).Android
