Automatically animates views to their new positions when the next layout happens.

A common way to use this API is to call it before updating the state hook in functional components and calling setState in class components.

Note that in order to get this to work on Android you need to set the following flags via UIManager:

if (Platform.OS === 'android') {

if (UIManager.setLayoutAnimationEnabledExperimental) {

UIManager.setLayoutAnimationEnabledExperimental(true);

}

}

Example

import React, { useState } from "react"; import { LayoutAnimation, Platform, StyleSheet, Text, TouchableOpacity, UIManager, View } from "react-native"; if ( Platform.OS === "android" && UIManager.setLayoutAnimationEnabledExperimental ) { UIManager.setLayoutAnimationEnabledExperimental(true); } const App = () => { const [expanded, setExpanded] = useState(false); return ( <View style={style.container}> <TouchableOpacity onPress={() => { LayoutAnimation.configureNext(LayoutAnimation.Presets.spring); setExpanded(!expanded); }} > <Text>Press me to {expanded ? "collapse" : "expand"}!</Text> </TouchableOpacity> {expanded && ( <View style={style.tile}> <Text>I disappear sometimes!</Text> </View> )} </View> ); }; const style = StyleSheet.create({ tile: { background: "lightGrey", borderWidth: 0.5, borderColor: "#d6d7da" }, container: { flex: 1, justifyContent: "center", alignItems: "center", overflow: "hidden" } }); export default App;

Methods

configureNext()

static configureNext(config, onAnimationDidEnd?)

Schedules an animation to happen on the next layout.

Parameters:

Name	Type	Required	Description
config	object	Yes	See config description below.
onAnimationDidEnd	function	No	Called when the animation finished. Only supported on iOS.

The config parameter is an object with the keys below. create returns a valid object for config, and the Presets objects can also all be passed as the config.

• duration in milliseconds
• create, optional config for animating in new views
• update, optional config for animating views that have been updated
• delete, optional config for animating views as they are removed

The config that's passed to create, update, or delete has the following keys:

• type, the animation type to use
• property, the layout property to animate (optional, but recommended for create and delete)
• springDamping (number, optional and only for use with type: Type.spring)
• initialVelocity (number, optional)
• delay (number, optional)
• duration (number, optional)

---

create()

static create(duration, type, creationProp)

Helper that creates an object (with create, update, and delete fields) to pass into configureNext. The type parameter is an animation type, and the creationProp parameter is a layout property.

Example usage:

• Function Component Example
• Class Component Example

import React, { Component, useState } from "react"; import { View, Platform, UIManager, LayoutAnimation, StyleSheet, Button } from "react-native"; if ( Platform.OS === "android" && UIManager.setLayoutAnimationEnabledExperimental ) { UIManager.setLayoutAnimationEnabledExperimental(true); } export default function App() { const [boxPosition, setBoxPosition] = useState("left"); const toggleBox = () => { LayoutAnimation.configureNext( LayoutAnimation.create( 500, LayoutAnimation.Types.spring, LayoutAnimation.Properties.scaleXY ) ); setBoxPosition(boxPosition === "left" ? "right" : "left"); }; return ( <View style={styles.container}> <View style={styles.buttonContainer}> <Button title="Toggle Layout" onPress={toggleBox} /> </View> <View style={[styles.box, boxPosition === "left" ? null : styles.moveRight]} /> </View> ); } const styles = StyleSheet.create({ container: { flex: 1, alignItems: "flex-start", justifyContent: "center" }, box: { height: 100, width: 100, borderRadius: 5, margin: 8, backgroundColor: "blue" }, moveRight: { alignSelf: "flex-end", height: 200, width: 200 }, buttonContainer: { alignSelf: "center" } });

import React, { Component } from "react"; import { View, Platform, UIManager, LayoutAnimation, StyleSheet, Button } from "react-native"; if ( Platform.OS === "android" && UIManager.setLayoutAnimationEnabledExperimental ) { UIManager.setLayoutAnimationEnabledExperimental(true); } export default class App extends Component { state = { boxPosition: "left" }; toggleBox = () => { LayoutAnimation.configureNext( LayoutAnimation.create( 500, LayoutAnimation.Types.spring, LayoutAnimation.Properties.scaleXY ) ); this.setState({ boxPosition: this.state.boxPosition === "left" ? "right" : "left" }); }; render() { return ( <View style={styles.container}> <View style={styles.buttonContainer}> <Button title="Toggle Layout" onPress={this.toggleBox} /> </View> <View style={[ styles.box, this.state.boxPosition === "left" ? null : styles.moveRight ]} /> </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, alignItems: "flex-start", justifyContent: "center" }, box: { height: 100, width: 100, borderRadius: 5, margin: 8, backgroundColor: "blue" }, moveRight: { alignSelf: "flex-end", height: 200, width: 200 }, buttonContainer: { alignSelf: "center" } });

Properties

Types

An enumeration of animation types to be used in the create method, or in the create/update/delete configs for configureNext. (example usage: LayoutAnimation.Types.easeIn)

Types
spring
linear
easeInEaseOut
easeIn
easeOut
keyboard

---

Properties

An enumeration of layout properties to be animated to be used in the create method, or in the create/update/delete configs for configureNext. (example usage: LayoutAnimation.Properties.opacity)

Properties
opacity
scaleX
scaleY
scaleXY

---

Presets

A set of predefined animation configs to pass into configureNext.

Presets	Value
easeInEaseOut	create(300, 'easeInEaseOut', 'opacity')
linear	create(500, 'linear', 'opacity')
spring	{ duration: 700, create: { type: 'linear', property: 'opacity' }, update: { type: 'spring', springDamping: 0.4 }, delete: { type: 'linear', property: 'opacity' } }

---

easeInEaseOut()

Calls configureNext() with Presets.easeInEaseOut.

---

linear()

Calls configureNext() with Presets.linear.

---

spring()

Calls configureNext() with Presets.spring.
