RoundedCorners not work

[mt131]

holder.imageViewCover.scaleType = ImageView.ScaleType.CENTER_CROP
holder.imageViewCover.load(producList[position].cover_image) {
transformations(RoundedCornersTransformation(32f))
}

but the image is not rounded conner

@mt131 Could you add more details about it?

[mt131]

it is an imageView in a recycleview

    android:id="@+id/imageViewCover"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="4dp"
    android:layout_marginEnd="8dp"
    android:layout_marginBottom="4dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.5"

override fun onBindViewHolder(holder: Song2Holder, position: Int) {

    holder.imageViewCover.scaleType = ImageView.ScaleType.CENTER_CROP
    holder.imageViewCover.load(producList[position].cover_image) {
        transformations(RoundedCornersTransformation(32f))
    }
   

}

It is not working fine for me either.
Some pictures are rounded but other ones not.
It is the same case, I am trying to load pictures into a recyclerView that has a GridLayoutManager with three columns. The holder will take the size depending on the screen size, and it is always squared thanks to the constraint condition I add to the picture (app:layout_constraintDimensionRatio="H,1:1")

It is my ImageView xml:

<ImageView
        android:id="@+id/file_image"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_margin="1dp"
        android:scaleType="centerCrop"
        android:adjustViewBounds="true"
        app:layout_constraintDimensionRatio="H,1:1"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        />

The RoundedCornersTransformation does work, but what I found while testing is that the source Bitmap is rounded, not the ImageView itself (which is probably what you're expecting). So if the image ends up rounded, then scaled into the Imageview via centercrop (the ScaleType you specified), you'll lose those corners.

I was also expecting "RoundedCornersTransformation" to round the image post-scaling so you see those transformations in the view itself.

@FrostRocket Yep, it's "technically" working, though definitely not the desired behaviour. Tracking the fix here.
