                resource: Drawable?,
                model: Any?,
                target: Target<Drawable>?,

                myContext.toast("resource ready")

// holder.img.setImageDrawable(resource) return true } }) .error(R.drawable.neterror) .into(holder.img) }

Glide depends on the returned boolean from the onResourceReady method of RequestListener , if the returned value is true (which is your case) it means that the listener has handled setting the resource on the target. To allow Glide's request to update the target return false . For more information checkout the docs: https://bumptech.github.io/glide/doc/debugging.html#requestlistener-and-custom-logs
