Rotate Image View Using Animation

This is an Example of React Native Rotate Image View Using Animation. We are using the property ofAnimatedComponent fromreact-native.

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-clicommand 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.

CodeRotate Image View Using Animation

Open App.js in any code editor and replace the code with the following code.

App.js

import  React ,{useState,useEffect}from 'react';
import { View ,StyleSheet,Animated,
  Image,
  Dimensions,
  Easing} from 'react-native';
  const {height} = Dimensions.get('window');
const App=({navigation})=> {
  const animation = useState(new Animated.Value(0))[0];
  const CallAnimation=()=>{
    animation.setValue(0);
    Animated.timing(animation, {
      toValue: 1,
      duration: 3000,
      useNativeDriver:false,
      easing: Easing.linear,
    }).start(() => CallAnimation());
  }
  useEffect(() => {
    CallAnimation();
  }, [])
  const RotateData = animation.interpolate({
    inputRange: [0, 1],
    outputRange: ['0deg', '360deg'],
  });
    return (
      <View style={styles.container}>
       <Animated.Image
        style={[styles.image,{transform: [{ rotate: RotateData }]}]}
        source={{uri: 'https://s3.amazonaws.com/media-p.slid.es/uploads/alexanderfarennikov/images/1198519/reactjs.png'}}
       >
      </Animated.Image>
    </View>
    );
  }
  const styles = StyleSheet.create({
    container: {
      flex: 1,
      justifyContent: 'center',
      alignItems: 'center'
    },
    image: {
      width: '60%',
      height:height/2.8,
      resizeMode:'contain'
    },
  })
  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

react-native run-ios
 (macOS only).
