Flip Image View Using Animation
This is an Example to Flip Image View Horizontally Using Animation in React Native. We are using the property of Animated
Component from react-native
.
To flip the image view horizontally using animation, We will flip the image on the click of Button. So let’s get started.
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
npm install -g react-native-cli
Run the following commands to create a new React Native project
react-native init ProjectName
If you want to start a new project with a specific React Native version, you can use the --version argument:
react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next
This will make a project structure with an index file named App.js in your project directory.
Code
Open App.js in any code editor and replace the code with the following code.
App.js
// Flip Image View Horizontally Using Animation in React Native
// https://aboutreact.com/react-native-flip-image-horizontally-using-animation/
// import React in our code
import React from 'react';
// import all the components we are going to use
import {
SafeAreaView,
StyleSheet,
View,
Text,
TouchableOpacity,
Animated,
} from 'react-native';
const App = () => {
let animatedValue = new Animated.Value(0);
let currentValue = 0;
animatedValue.addListener(({ value }) => {
currentValue = value;
});
const flipAnimation = () => {
if (currentValue >= 90) {
Animated.spring(animatedValue, {
toValue: 0,
tension: 10,
friction: 8,
useNativeDriver: false,
}).start();
} else {
Animated.spring(animatedValue, {
toValue: 180,
tension: 10,
friction: 8,
useNativeDriver: false,
}).start();
}
};
const setInterpolate = animatedValue.interpolate({
inputRange: [0, 180],
outputRange: ['180deg', '360deg'],
});
const rotateYAnimatedStyle = {
transform: [{ rotateY: setInterpolate }],
};
return (
<SafeAreaView style={{ flex: 1 }}>
<View style={styles.container}>
<Text style={styles.titleText}>
React Native Flip Image View Horizontally with Animation
</Text>
<Animated.Image
source={{
uri:
'https://raw.githubusercontent.com/AboutReact/sampleresource/master/desktop-computer-screen-with-arrow-to-the-left-and-coin-stack.png',
}}
style={[rotateYAnimatedStyle, styles.imageStyle]}
/>
<TouchableOpacity
style={styles.buttonStyle}
onPress={flipAnimation}>
<Text style={styles.buttonTextStyle}>
Click Here To Flip The Image
</Text>
</TouchableOpacity>
</View>
</SafeAreaView>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
},
titleText: {
fontSize: 22,
textAlign: 'center',
fontWeight: 'bold',
},
buttonStyle: {
fontSize: 16,
color: 'white',
backgroundColor: 'green',
padding: 5,
marginTop: 32,
minWidth: 250,
},
buttonTextStyle: {
padding: 5,
color: 'white',
textAlign: 'center',
},
imageStyle: {
width: 150,
height: 150,
borderRadius: 6,
},
});
export default App;
To Run the React Native App
Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running (macOS only)
react-native run-ios
