Glide 4.7.1 placeholder not loading

Question

I am trying to load a placeholder image using GlideLibrary and I am using SimpleTarget. The placeholder image is not loading but the image from the url is loading. I have searched a lot and used RequestOptions as well. Still, it doesn't seem to work.

Below is the code :

Glide.with(mContext).load("https://i.imgur.com/0k7ZFWr.png").apply(RequestOptions.placeholderOf(R.drawable.pubgguide_icon)).into(new SimpleTarget<Drawable>() {
        @Override
        public void onResourceReady(Drawable resource, Transition<? super Drawable> transition) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                holder.cardImageLayout.setBackground(resource);
                Drawable cardViewBackground = holder.cardImageLayout.getBackground();
                cardViewBackground.setColorFilter(0x5F000000, PorterDuff.Mode.SRC_ATOP);
            }
        }
    });

I am using Glide library 4.7.1. I have tried using setDefaultRequestOptions() as well - not working.

My cardview XML:

Answer 1

You can like this with Glide (4.7.1)

Glide.with(getActivity()).load(avatar)
                .apply(RequestOptions.bitmapTransform(new CircleCrop()).placeholder(R.mipmap.defaultusericon))
                .into(mUserIcon);

Answer 2

placeHolderOf sets place Holder image only if you are loading it in an ImageView. If you want to set place holder to a ViewGroup, SimpleTarget class provides a method which you can override to set background when image starts loading.
In your case try loading like below :

Glide.with(mContext)
            .load("https://i.imgur.com/0k7ZFWr.png")
            .apply(RequestOptions.placeholderOf(R.drawable.pubgguide_icon))
            .into(new SimpleTarget<Drawable>() {

                @Override
                public void onLoadStarted(@Nullable Drawable resource) {
                    holder.cardImageLayout.setBackground(resource);
                }

                @Override
                public void onResourceReady(@NonNull Drawable resource, Transition<? super Drawable> transition) {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                        holder.cardImageLayout.setBackground(resource);
                        Drawable cardViewBackground = holder.cardImageLayout.getBackground();
                        cardViewBackground.setColorFilter(0x5F000000, PorterDuff.Mode.SRC_ATOP);
                    }
                }
            });
