Pressable

Pressable is a Core Component wrapper that can detect various stages of press interactions on any of it's defined children.

<Pressable onPress={onPressFunction}>
<Text>I'm pressable!</Text>
</Pressable>

How it works

On an element wrapped by Pressable:

  • onPressIn is called when a press is activated.
  • onPressOut is called when the press gesture is deactivated.

After pressing onPressIn, one of two things will happen:

  1. The person will remove their finger, triggering onPressOut followed by onPress.
  2. If the person leaves their finger longer than 370 milliseconds before removing it, onLongPress is triggered. (onPressOut will still fire when they remove their finger.)

Fingers are not the most precise instruments, and it is common for users to accidentally activate the wrong element or miss the activation area. To help, Pressable has an optional HitRect you can use to define how far a touch can register away from the wrapped element. Presses can start anywhere within a HitRect.

PressRect allows presses to move beyond the element and its HitRect while maintaining activation and being eligible for a "press"—think of sliding your finger slowly away from a button you're pressing down on.

The touch area never extends past the parent view bounds and the Z-index of sibling views always takes precedence if a touch hits two overlapping views.

Diagram of HitRect and PressRect and how they work.
You can set HitRect with hitSlop and set PressRect with pressRetentionOffset.

Pressable uses React Native's Pressability API. For more information around the state machine flow of Pressability and how it works, check out the implementation for Pressability.

Example

import React, { useState } from 'react';
import { Pressable, StyleSheet, Text, View } from 'react-native';
const App = () => {
const [timesPressed, setTimesPressed] = useState(0);
let textLog = '';
if (timesPressed > 1) {
textLog = timesPressed + 'x onPress';
} else if (timesPressed > 0) {
textLog = 'onPress';
}
return (
<View>
<Pressable
onPress={() => {
setTimesPressed((current) => current + 1);
}}
style={({ pressed }) => [
{
backgroundColor: pressed
? 'rgb(210, 230, 255)'
: 'white'
},
styles.wrapperCustom
]}>
{({ pressed }) => (
<Text style={styles.text}>
{pressed ? 'Pressed!' : 'Press Me'}
</Text>
)}
</Pressable>
<View style={styles.logBox}>
<Text testID="pressable_press_console">{textLog}</Text>
</View>
</View>
);
};
const styles = StyleSheet.create({
text: {
fontSize: 16
},
wrapperCustom: {
borderRadius: 8,
padding: 6
},
logBox: {
padding: 20,
margin: 10,
borderWidth: StyleSheet.hairlineWidth,
borderColor: '#f0f0f0',
backgroundColor: '#f9f9f9'
}
});
export default App;
