Background
I have an image placed on a screen meant to show when the screen loads other content.
I want to center the image so it is always center on all devices.
Problem
Currently the image shows up top center. I would like it to be aligned vertically as well. Also to be sure that it will always look the same on all devices.
Question
What is the solution to make sure the image is always centered and the right size for all devices?
Example,
My current code,
In Photoshop
Image is 300 Resolution Height is 776 px Width is 600 px
I want the image to be centered horizontally and vertically in all devices and look good without pixelating. Natively I know I need to set the image sizes. But from my understanding in React Native I can use on image but then use JSX to handle it being responsive.
import React from 'react'; import { StyleSheet, View, Image, } from 'react-native'; const logo = require('../images/logo.jpg'); const LoadingScreen = () => ( <View> <Image style={styles.logo} source={logo} /> </View> ); const styles = StyleSheet.create({ logo: { justifyContent: 'center', alignItems: 'center', width: 300, height: 400, }, }); export default LoadingScreen;
To vertically align image with resizeMode "contain" with React Native, we can use justifyContent . to set justifyContent to 'center' to center align the Image vertically. We also set the image height and width to make it display. As a result, we should see the image display vertically centered.
To center any component using the flexbox, we simply need to simply set the flex property as 1, along with the justifyAlign and alignItems properties. Using CSS position property: The position property is less widely used in React Native to center any components.
Right aligning a component can be hard in React Native, especially when you don't want to just use text-align: right . Luckily, you can use flexbox to right-align an element by setting two properties on a wrapping View .
You need to set the style of <View>
for justifyContent
and alignItems
for centering the <Image>
.
Should be like this :
const LoadingScreen = () => ( <View style={styles.container}> <Image style={styles.logo} source={logo} /> </View> ); const styles = StyleSheet.create({ container: { justifyContent: 'center', alignItems: 'center', }, logo: { width: 300, height: 400, }, });
Or you can use alignSelf
on the <Image>
to make it center, but it will still need to add justifyContent
on <View>
to make it center vertically.
