Invalid behavior Pressable in ScrollView

[jfrolich]

Description

The delayPressIn was set to 0 in this commit. 86ffb9c. This removes the delay for pressing a button. This is fine if the button is not in a ScrollView but this delay is designed to not trigger pressIn while scrolling (see native iOS touchables). So basically every Pressable that's being used in a ScrollView has invalid behavior.

React Native version:

0.63.4

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Put a pressable in a ScrollView
2. Try to scroll above a button
3. The button triggers

Expected Results

There should be a way to set this delay (it is delayPressIn is not available on the Pressable component). I think it best to:

• Set the default back to 130ms
• make the delay configurable on the Pressable component

This is because in my experience most Pressables are part of a ScrollView, and if they're not part of a ScrollView, the small delay is unnoticeable (it might even be the same for native controls). If a delay of 130ms is not acceptable (perhaps in a game scenario or something like that) it can be configured.

There's some related discussion in #29376 where the regression was reported.

The change to 0 is actually important.

A lot of UI pressables are NOT in scrollviews. Consider the back button for navigation. Prior to the aforementioned change there would be no feedback for when it was pressed, because the delay was too long before the new screen slid in.

An unstable_pressDelay property does exist on Pressable (although it's not on the Typescript types), documented here: #29376 (comment)

Does anyone have answer for this problem. I have a Pressable in ScrollView, but the pressable doesn't let me scroll because the scroll trigers the press event

Hello @Firesoul18 , @jfrolich :)

I have exactly the same problem (I've already asked the question here, but no relevant answer). Have you found a solution?

Thanks :)
