Adding Image
Let us create a new folder img inside the src folder. We will add our image (myImage.png) inside this folder.
We will show images on the home screen.
App.js
import React from 'react';
import ImagesExample from './ImagesExample.js'
const App = () => {
return (
<ImagesExample />
)
}
export default App
Local image can be accessed using the following syntax.
image_example.js
import React, { Component } from 'react'
import { Image } from 'react-native'
const ImagesExample = () => (
<Image source = {require('C:/Users/Tutorialspoint/Desktop/NativeReactSample/logo.png')} />
)
export default ImagesExamplereact native asign width to image
First import Dimensions from react-native
import { Dimensions } from 'react-native';
then you have to get the dimensions of the window
const win = Dimensions.get('window');
Now calculate ratio as
const ratio = win.width/541; //541 is actual image width
now the add style to your image as
imageStyle: {
width: win.width,
height: 362 * ratio, //362 is actual height of image
