android scroll is not smoth?

Open ios-dev-newbie opened this issue 6 years ago • 12 comments

I have a flat list. Inside of that flat list I have added the image zoom view. This is working perfectly in iOS. where as in android when I tried to swipe the page to view the next image the view get stuck.

I have to do lot of swipe to actually swipe the image. I feel that in android the scroll is not smooth.

Please let me know how to add the smooth scroll to view.

I'm using Animated.View to make smooth scroll, but it seems not perfect in android. Can anyone help?

setting renderToHardwareTextureAndroid={true} on the Animated.View (here: https://github.com/ascoders/react-native-image-zoom/blob/master/src/image-zoom/image-zoom.component.tsx#L672) fixed performance on android.

tested in release mode on a low-end device.

no PR, sorry..

Hi @ascoders , I am still facing this issue in Android, I have a home screen like Instagram, when I scroll down the list it works well in iOS, but in Android when I scroll the list specially, the image on which I am using your code, list does not scroll. I am using the latest version of your package "react-native-image-pan-zoom": "^2.1.11",

renderToHardwareTextureAndroid is already there in your file mentioned above by @marconett . But no help.

Please assist me.

FYI, setting renderToHardwareTextureAndroid={true} causes Android 6 and Android 7 devices to crash. My image was 2500px by 3000px so maybe that was too much for the GPU to hold in memory in these older phones.

How did you manage to do with Animated.View

Thanks for the suggestion @marconett, but adding the prop renderToHardwareTextureAndroid={true} didn't solve the problem. Images zoom and scroll perfectly in a FlatList on IOS but when I put my fingers on the image to scroll on Android, it's not working...

Any suggestions, please?
