Pinch to zoom gesture not working on Android when used inside ScrollView

[christianrank]

Describe the bug When the Crop component is used inside of a ScrollView, the image can't be zoomed with 2 fingers on Android, instead the ScrollView is moving. Just moving the image with 1 finger works fine.

On iOS, everything works as expected.

To Reproduce Steps to reproduce the behavior:

1. Put the <Crop> inside a <ScrollView>
2. Try to zoom the image with 2 fingers on Android
3. The screen is scrolling

Expected behavior Pinch to zoom should work on Android also when used inside a ScrollView.

Smartphone:

• OS: Android (tested with 7 and 11)

change import { ScrollView } from 'react-native'; to import { ScrollView } from 'react-native-gesture-handler';

I tried that already, it didn't work.

(tried with react-native-gesture-handler versions 1.10.3 and 2.1.0)

Try following scrollview props, if it still doesn't work please create a reproducible repo

//...
import { ScrollView } from 'react-native';

//...
<ScrollView 
disableScrollViewPanResponder={true}
nestedScrollEnabled={true}
pinchGestureEnabled={false}
>
<Crop>
//...
</ScrollView>

Thanks, I also didn't have luck with that.

I'm currently trying to setup a reproduction repo, but with a fresh project I can't get any gestures working on Android, even without using a ScrollView on this screen I can't move the image now. It's working fine on iOS.

So this repo isn't showing the bug yet, but something else is already broken.

I'm giving up for today, but maybe you have an idea?

The example already uses a scrollview and it works, https://github.com/vemarav/react-native-avatar-crop/blob/d0910826126869e22d82aa2d8acc0762df1a1fe9/example/CropImage.tsx#L46

use react-native-gesture-handler@1.10.3

WIP to support react-native-gesture-handler v2
