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