In this lesson we will use Animated.timing to animate the opacity and height of a View in our React Native application. This function has attributes that you can set such as easing and duration.

 

import React, {Component} from ‘react‘;import {Text, View, StyleSheet, Image, Animated, Easing} from ‘react-native‘;var styles = StyleSheet.create({    container: {        backgroundColor: ‘#48BBEC‘,        paddingBottom: 10    },    name: {        alignSelf: ‘center‘,        fontSize: 21,        marginTop: 10,        marginBottom: 5,        color: ‘white‘    },    handle: {        alignSelf: ‘center‘,        fontSize: 16,        color: ‘white‘    },    image: {        height: 125,        width: 125,        borderRadius: 65,        marginTop: 10,        alignSelf: ‘center‘    }});class Badge extends React.Component {    constructor(props){        super(props);        this.state = {            fadeAnim: new Animated.Value(0),            bounceAnim: new Animated.Value(0)        }    }    componentDidMount() {        Animated.timing(            this.state.fadeAnim,            {toValue: 1, duration: 2000}        ).start();        Animated.timing(            this.state.bounceAnim,            {toValue: 1, duration: 2000, easing: Easing.bounce}        ).start();    }    render(){        const animatedTextStyle = {            opacity: this.state.fadeAnim,        };        const animateImageStyle = {            opacity: this.state.bounceAnim        };        return (            <View style={styles.container}>                <Animated.Image style={[styles.image, animateImageStyle]} source={{uri: this.props.userInfo.avatar_url}}></Animated.Image>                <Animated.Text style={[styles.name,animatedTextStyle]}> {this.props.userInfo.name} </Animated.Text>                <Animated.Text style={[styles.handle, animatedTextStyle]}> {this.props.userInfo.login} </Animated.Text>            </View>        )    }}/** * Make sure when when user the Badge component, the userInfo object is there * @type {{userInfo: *}} */Badge.propTypes = {    userInfo: React.PropTypes.object.isRequired};module.exports=Badge;
