Button

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 TouchableWithoutFeedback. 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';

const Separator = () => <View style={styles.separator} />;

const App = () => (
  <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>
