React Native setTimeout Method
We will demonstrate in this short article how to implement setTimeout in React Native.
Use the setTimeout Method in React Native
We may occasionally need to execute code after a few seconds. In such circumstances, we use React Native’s JavaScript API setTimeout.
The setTimeout method performs a function after a specified time has passed.
Code Example:
import React from 'react';
import {Button, Image, StyleSheet, View} from 'react-native';
const App = () => {
const [image, setImage] = React.useState(null);
const showImage = () => {
setTimeout(() => {
setImage(
'https://www.casio.com/content/dam/casio/product-info/locales/us/en/timepiece/product/watch/G/GM/gm2/gm-2100-1a/assets/GM-2100-1A.png.transform/main-visual-pc/image.png');
}, 3000);
};
return (
<View style={styles.container}>
<View style={styles.imageContainer}>
<Image
source={
{ uri: image }}
style={
{ width: '100%', height: 160 }}
resizeMode='contain'
/>
</View>
<View style={styles.buttonContainer}>
<Button
title="Click On the button to see the image"
onPress={() => showImage()}
/>
</View>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 0.85,
justifyContent: 'center',
paddingHorizontal: 10,
},
buttonContainer: {
marginTop: 10,
},
imageContainer: {
justifyContent: 'center',
alignItems: 'center',
},
});
export default App;
Here, we have code to delay a load of images using the setTimeOut method, which slows the images’ loading by 3000 milliseconds, precisely 3 seconds. We have declared a showImage method that uses a setTimeOut method.
The showImage method is invoked in the button, which triggers using the onPress method of JavaScript.
Output:
The image will appear after 3 seconds when you click on the button.
