Your library is really good but It s crash when render a bigger image.

AppCompatImageView not displayed because it is too large to fit into a software layer (or drawing cache), needs 10765440 bytes, only 8294400 available

I need my image to be only able to zoom in

Hi, some compliments for the lib, it is the most powerful pinch to zoom that exist 👍
But I have a problem after release one finger: the view is moved down.

Here the xml: https://www.dropbox.com/s/qhy607wi45rb803/activity.xml?dl=0
Here the view before zoom: https://www.dropbox.com/s/mfe0ocijvrolggi/1.png?dl=0
Here the view after release one finger from zoom: https://www.dropbox.com/s/4am83s6tnonnqko/2.png?dl=0

I've colored view to know which is moved.

Can you help me?

Thanks!

i want only zoom on pinch not move any where on screen. how can i achieve it

How I can override this method in fragment?
@Override public boolean dispatchTouchEvent(MotionEvent ev) { return imageZoomHelper.onDispatchTouchEvent(ev) || super.dispatchTouchEvent(ev); }

I have implemented the zoom feature in side nested recycler view, i.e i want to apply zoom to an image view present in a horizontal recycler view which is again in a vertical recycler view.

please find the image.

When pinch start on image and end , image view flikers due to setting placeHolderView background

how to set minimum scale so the zoom image can't be smaller than original imageview size?

The application element in the manifest causes merge failures when the library is used in an application with allowBackup="true".

https://github.com/okaybroda/ImageZoom/blob/master/library/src/main/AndroidManifest.xml

It is possible to override with 'tools:replace="android:allowBackup", but it would be nice if the property can be used as intended.

I have one recyclerview which needs to be zoomed, i wrapped it with frame layout and gave id 'zoomable'. There are other view also, in my case recyclerview should be zoomed within its bound only.
Issue is : recyclerview is poped out of its place and is zooming all over the screen.

@OverRide
public boolean dispatchTouchEvent(MotionEvent ev) {
return imageZoomHelper.onDispatchTouchEvent(ev) || super.dispatchTouchEvent(ev);
}

Hello,
This is not a issue but I am trying to achieve the functionality like zooming image from its touch coordinates. can you help me through it ?
updateZoomableViewMargins(newCenter[0] - twoPointCenter[0] + originalXY[0], newCenter[1] - twoPointCenter[1] + originalXY[1]);
I tried a lot to tweaking above code segment but couldn't get success.

When i do a zoom out, there is a little flick in the imageview.
The ImageView is inside a RecyclerView and its loaded with Glide.

I am facing one issue when using ImageZoom inside recyclerview. The issue is that, whole image or some part of image becomes invisible at the time of zooming.
(I have wrapped ImageView in FrameLayout as mention in library use case description )
Please refer following screenshots for more details of issues.
Before zooming:

After zooming:

As you can seen in second screenshot after zooming first image multiple time first image goes invisible and after zooming second image multiple times , some part of image goes invisible...

Hello, I found this issue on various devices, it mostly happens in Samsung devices, any idea how to fix it?

Seems likes when we reach the onAnimationUpdate in ImageZoomHelper(line 162) the zoomableView is null, any idea why this happends?

If we add a this.zoomableView != null in that method do you think it will be fixed?

Any help I'll be grateful.

When you initially grab the image, there is a huge flicker! I found this even on your sample app, so I know it's not anything I did when integrating into my project.

This library is working well with Fragment, but not DialogFragment. How to solve this issue?

Hi I'm really proud and apprciate it about this library help me on Activity, can you give me knowledge how to setup in RecyclerView Adapter event we have create adapter on Class? Because I didn't know how to setup ImageZoomHelper imageZoomHelper; and imageZoomHelper = new ImageZoomHelper(this); also for dispatchTouchEvent.

Thanks and Regards
