Pressable

Pressable is a Core Component wrapper that can detect various stages of press interactions on any of its 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 500 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#

Props#

android_disableSound
Android
#

If true, doesn't play Android system sound on press.

TypeDefault
booleanfalse

android_ripple
Android
#

Enables the Android ripple effect and configures its properties.

Type
RippleConfig

children#

Either children or a function that receives a boolean reflecting whether the component is currently pressed.

Type
React Node

unstable_pressDelay#

Duration (in milliseconds) to wait after press down before calling onPressIn.

Type
number

delayLongPress#

Duration (in milliseconds) from onPressIn before onLongPress is called.

TypeDefault
number500

disabled#

Whether the press behavior is disabled.

TypeDefault
booleanfalse

hitSlop#

Sets additional distance outside of element in which a press can be detected.

Type
Rect or number

onLongPress#

Called if the time after onPressIn lasts longer than 500 milliseconds. This time period can be customized with delayLongPress.

Type
({ nativeEvent: PressEvent }) => void

onPress#

Called after onPressOut.

Type
({ nativeEvent: PressEvent }) => void

onPressIn#

Called immediately when a touch is engaged, before onPressOut and onPress.

Type
({ nativeEvent: PressEvent }) => void

onPressOut#

Called when a touch is released.

Type
({ nativeEvent: PressEvent }) => void

pressRetentionOffset#

Additional distance outside of this view in which a touch is considered a press before onPressOut is triggered.

TypeDefault
Rect or number{ bottom: 30, left: 20, right: 20, top: 20 }

style#

Either view styles or a function that receives a boolean reflecting whether the component is currently pressed and returns view styles.

Type
View Style

testOnly_pressed#

Used only for documentation or testing (e.g. snapshot testing).

TypeDefault
booleanfalse

Type Definitions#

RippleConfig#

Ripple effect configuration for the android_ripple property.

Type
object

Properties:

NameTypeRequiredDescription
colorcolorNoDefines the color of the ripple effect.
borderlessbooleanNoDefines if ripple effect should not include border.
radiusnumberNoDefines the radius of the ripple effect.
foregroundbooleanNoSet to true to add the ripple effect to the foreground of the view, instead of the background. This is useful if one of your child views has a background of its own, or you're e.g. displaying images, and you don't want the ripple to be covered by them.
