Photoview: The ImageView's ScaleType has been changed since attaching a PhotoViewAttacher

java.lang.IllegalStateException: The ImageView's ScaleType has been changed since attaching a PhotoViewAttacher

This has become a really annoying problem in Fragments. It appears to be caused by shared element transitions on Lollipop, the OS's scaling transition animation must change the scale type.

I have found the same problem.Do you have solved it?

[maf2356]

call the PhotoViewAttacher.cleanup before u calling onBackPressed or ondestory

谢谢

There is another case that trigger this bug without make the ImageView inside a Fragment. We just need to remove all scale animations from Developer Options

I tried use photoViewAttacher.cleanup(); before onDestroy and onStop but it didn't work

Here is the complete stacktrace

+1 Encountering the same issue here.

I also encountered this on version 1.3.1 and I used the same workaround as with the ViewPager.
I created the following class:

public class MyPhotoViewAttacher extends PhotoViewAttacher {

    public MyPhotoViewAttacher(ImageView imageView) {
        super(imageView);
    }

    public MyPhotoViewAttacher(ImageView imageView, boolean zoomable) {
        super(imageView, zoomable);
    }

    @Override
    public void onGlobalLayout() {
        try {
            super.onGlobalLayout();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

and then just use it as I would use the original PhotoViewAttacher:
final MyPhotoViewAttacher attacher = new MyPhotoViewAttacher(imageView);
