A basic button component that should render nicely on any platform. Supports a minimal level of customization.

If this button doesn't look right for your app, you can build your own button using TouchableOpacity or TouchableNativeFeedback. For inspiration, look at the source code for this button component. Or, take a look at the wide variety of button components built by the community.

<Button

onPress={onPressLearnMore}

title="Learn More"

color="#841584"

accessibilityLabel="Learn more about this purple button"

/>

Example

import React from 'react';

import { StyleSheet, Button, View, SafeAreaView, Text, Alert } from 'react-native';

import Constants from 'expo-constants';

function Separator() {

return <View style={styles.separator} />;

}

export default function App() {

return (

<SafeAreaView style={styles.container}>

<View>

<Text style={styles.title}>

The title and onPress handler are required. It is recommended to set

accessibilityLabel to help make your app usable by everyone.

</Text>

<Button

title="Press me"

onPress={() => Alert.alert('Simple Button pressed')}

/>

</View>

<Separator />

<View>

<Text style={styles.title}>

Adjust the color in a way that looks standard on each platform. On

iOS, the color prop controls the color of the text. On Android, the

color adjusts the background color of the button.

</Text>

<Button

title="Press me"

color="#f194ff"

onPress={() => Alert.alert('Button with adjusted color pressed')}

/>

</View>

<Separator />

<View>

<Text style={styles.title}>

All interaction for the component are disabled.

</Text>

<Button

title="Press me"

disabled

onPress={() => Alert.alert('Cannot press this one')}

/>

</View>

<Separator />

<View>

<Text style={styles.title}>

This layout strategy lets the title define the width of the button.

</Text>

<View style={styles.fixToText}>

<Button

title="Left button"

onPress={() => Alert.alert('Left button pressed')}

/>

<Button

title="Right button"

onPress={() => Alert.alert('Right button pressed')}

/>

</View>

</View>

</SafeAreaView>

);
