Please tell me your source code.
the following code is sample.

Glide.with(mContext)
  .load(R.drawable.demo)
  .bitmapTransform(new CenterCrop(mContext), new RoundedCornersTransformation(mContext, 100, 0))
  .into(holder.image);

your code can work ok。
my code is:
Glide.with(context)
.load(realUrl)
.centerCrop()
.placeholder(R.drawable.default_avatar)
.error(R.drawable.default_avatar)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.bitmapTransform(new RoundedCornersTransformation(context,8,0))
.into(imageView);

@wasabeef from what I understand, we cannot use Glide's centerCrop() if we use bitmapTransform?

@leixinstar

Yeah..

It can't be used centerCrop if you use the bitmapTransform

RoundedCornersTransformation and CropTransformation(mContext, 300, 100, CropTransformation.CropType.TOP)，how can this two work together?

Removing centerCrop fixed the issue for me. Thanks

Check the code of centerCrop/fitCenter/dontTransfrom/bitmapTransform they all call transform. To combine two transformations you need to use the varargs version and forget about the convenience methods:

.transform(new CenterCrop(context), new RoundedTransformation(...))

@wasabeef I think you should update https://github.com/wasabeef/glide-transformations#advanced-step-3 with the information that .centerCrop() in a combined usage becomes new CenterCrop(context) (similar for fitCenter.

@TWiStErRob that doesn't work either, same results

OK I was able to make it work by tweaking RoundedCornersTransformation. In the transform() method, you should use outWidth and outHeight instead of the source bitmap width/height

Sorry, I was wrong about .transform(...) I always forget that @wasabeef's transformations are Transformation<Bitmap> and not BitmapTransformation, using .bitmapTransform(...) works as expected, see #40 (comment).

In Adapter, sometime it is ok, but sometime, not, my code :

 if(opts.getRadius() != 0) {
            builder.bitmapTransform(new FitCenter(imageView.getContext()),
                    new RoundedCornersTransformation(imageView.getContext(),
                            opts.getRadius(), 0));
        }else {
            builder.bitmapTransform(new FitCenter(imageView.getContext()));
        }
