With the update react native
to version 0.63
, new components have appeared. Can someone more experienced explain how the Pressable
differs from the TouchableOpacity
and when it is better to use them.
回答1:
Pressable was a new introduction to RN 0.63, prior to that,Touchable Opacity was the most common used Component to wrap a component or simliar components.
Both their basic functionalities are same, to make a text/image clickable and user interactive.
But with Pressable
you get to access a lot new props like :
HitRect
, which is such a cool feature, acc to docs :
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 optionalHitRect
you can use to define how far a touch can register away from the the wrapped element. Presses can start anywhere within aHitRect
.
This is clearly a better alternative to what we used for hitslop
, here its more precise and you define the area.And it doesnt interfere with the child/other components Z-index too.
So basically you get all the feature of a button, touchableOpacity with cool new props. Do check out thier docs : rn-pressable
Hopeit helps.feel free for doubts

Here is a picture to clear your doubt.
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:
- The person will remove their finger, triggering onPressOut followed by onPress.
- 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.)
Please refer to documentation for more details.
