What is the TouchableOpacity?
TouchableOpacity is one of the touchable components in React Native that are broadly used for registering touch or press events on views (such as buttons or cards).
This component fades out when pressed and fades back in when released.
TouchableOpacity wraps children in an Animated.View to control the opacity, which is added the view hierarchy. Be aware that this can shift the layout of your application.
import { TouchableOpacity, Text } from 'react-native';
<TouchableOpacity onPress={() => console.log('Button pressed')}>
<Text>Press Button</Text>
</TouchableOpacity>
Styling TouchableOpacity
Similar to a View component, TouchableOpacity can be styled using the style property.
In this example we will make a regular primary button using TouchableOpacity. This and many other Pre-Built React Native Components can be found in our collection.
import { TouchableOpacity, Text } from 'react-native';
<TouchableOpacity style={styles.button}>
<Text style={styles.buttonText}>Press Button</Text>
</TouchableOpacity>
const styles = StyleSheet.create({
button: {
alignItems: 'center',
justifyContent: 'center',
borderRadius: 8,
paddingVertical: 8,
paddingHorizontal: 16,
borderWidth: 1,
backgroundColor: '#0569FF',
borderColor: '#0569FF',
},
buttonText: {
fontSize: 17,
lineHeight: 24,
fontWeight: '600',
color: '#fff',
}
})
Changing the opacity
You can use activeOpacity to change the opacity of the TouchableOpacity when it is active. Defaults to 0.2
import { TouchableOpacity, Text } from 'react-native';
<TouchableOpacity activeOpacity={0.6}>
<Text>Press Button</Text>
</TouchableOpacity>
