Photoview: この例外が発生する理由 'setScaleType〜を呼び出す必要があります'

これがどのように、そしてなぜ起こっているのかを知るために、ここにいくつかのコードを投稿していただけますか？

PhotoViewでPicasso PhotoViewを使用しています

• Kotlinコード

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コード

    <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" />

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

共有要素の遷移??

共有要素の遷移を使用しています

finishAfterTransitionメソッドをオーバーライドし、mAttacher.cleanup（）を呼び出します。
