Answer 1

If you want to do this in KOTLIN, you can try that way:

    Glide.with(context)
            .load(url)
            .listener(object : RequestListener<Drawable> {
                override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean): Boolean {
                    //TODO: something on exception
                }
                override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean {
                    Log.d(TAG, "OnResourceReady")
                    //do something when picture already loaded
                    return false
                }
            })
            .into(imgView)

Kotlin way

Glide.with(context)
                .load(image_url)
                .listener(object : com.bumptech.glide.request.RequestListener<Drawable> {
                    override fun onLoadFailed(
                        e: GlideException?,
                        model: Any?,
                        target: Target<Drawable>?,
                        isFirstResource: Boolean
                    ): Boolean {
                        return false
                    }

                    override fun onResourceReady(
                        resource: Drawable?,
                        model: Any?,
                        target: Target<Drawable>?,
                        dataSource: DataSource?,
                        isFirstResource: Boolean
                    ): Boolean {
                        img_product_banner.visibility = View.VISIBLE
                        return false
                    }

                }).placeholder(R.drawable.placeholder)
                .diskCacheStrategy(DiskCacheStrategy.ALL)
                .into(img_product_banner)

In exception put a condition for show again the ProgressBar

 Glide.with(context)
    .load(image_url)
    .listener(new RequestListener<String, GlideDrawable>() {
        @Override
        public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
            if(e instanceof UnknownHostException)
                progressBar.setVisibility(View.VISIBLE);
            return false;
        }

        @Override
        public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
            progressBar.setVisibility(View.GONE);
            return false;
        }
    })
    .into(imageView);

Update:

Glide.with(this)
            .load(imageUrl)
            .listener(new RequestListener<Drawable>() {
                @Override
                public boolean onLoadFailed(@Nullable final GlideException e,
                                            final Object model, final Target<Drawable> target,
                                            final boolean isFirstResource) {
                    showProgress(false);

                    mNoContentTextView.setVisibility(View.VISIBLE);

                    return false;
                }

                @Override
                public boolean onResourceReady(final Drawable resource, 
                                               final Object model, 
                                               final Target<Drawable> target, 
                                               final DataSource dataSource, 
                                               final boolean isFirstResource) {
                    showProgress(false);

                    mNoContentTextView.setVisibility(View.GONE);
                    mContentImageView.setImageDrawable(resource);

                    return false;
                }
            })
            .into(mContentImageView);

In Kotlin you can do like below

Glide.with(context)
            .setDefaultRequestOptions(RequestOptions().placeholder(R.drawable.ic_image_placeholder).error(R.drawable.ic_image_placeholder))
            .load(url)
            .listener(object : RequestListener<Drawable>{
                override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean): Boolean {
                    return false
                }

                override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean {
                    return false
                }

            })
            .into(imageView)
