why occur this exception 'You should call setScaleType ~'

[kangsLee]

When exiting an activity, the following error occurs:

The ImageView's ScaleType has been changed since attaching a PhotoViewAttacher. You should call setScaleType on the PhotoViewAttacher instead of on the ImageView

I don't use scaleType in the xml or Java code.
why this happened to me?

[Jawnnypoo]

Can you please post some code in here so that I can see how and why this is happening?

[kangsLee]

I'm using PhotoView with Picasso

• Kotlin Code

picasso.load(imageUrl).noPlaceholder().fit().rxInto(trans_imageview).subscribe({
            progressBar.visibility = View.GONE
            val photoView = PhotoViewAttacher(trans_imageview)
            photoView.update()
        }, {toast("Error : ${it.message}")})

• Xml Code

    <ImageView
        android:id="@+id/trans_imageview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:adjustViewBounds="true"
        android:transitionName="image" />

if press back button while touching photoView then ,

[kangsLee]

I 'm using shared elements transition

[bediy]

Override finishAfterTransition method and call mAttacher.cleanup().

[kangsLee]
