The sizes of the corner for the Image are different

ImageView in xml are all like this <ImageView android:id="@+id/iv_pic_three" android:layout_width="match_parent" android:layout_height="75dp" android:scaleType="fitXY"/>

public static void loadCornerImage(final Context context, String url, final ImageView imageView) {
    Glide.with(context).load(url).placeholder(R.mipmap.list_pic_loading).bitmapTransform(new RoundedCornersTransformation(context, 10, 0)
    ).diskCacheStrategy(DiskCacheStrategy.SOURCE).into(imageView);
}

Using a custom transformation removes Glide’s ability to auto-apply fitCenter/centerCrop so you need to help it out:

.bitmapTransform(new FitCenter(context), new RoundedCornersTransformation(context, 10, 0))

this will make image Bitmaps uniform in pixel size and hence the corners should have the same size.

@MrLaird I don’t see any difference in corner size, the lines of the right image may be deceiving to the eye: (created this by removing background, and flipping the right to the left image, and changing its transparency; the grey pixels are residue from imperfect background cutting)
