Shared element transition from RecyclerView to activity not working

Question

I want to use shared element transition from RecyclerView item to another Activity, but it's not working. The RecyclerView is inside a fragment, and this is onClick listener of RecyclerView item

  @Override 
    public void onProductItemClick(int pos, PromoORProduct promoORProduct, ImageView shareImageView) {

    Intent intent = new Intent(getActivity(), ProductPreviewAct_.class);
    intent.putExtra("OBJECT", promoORProduct);
    intent.putExtra(ProductPreviewAct.SMALL_IMAGE_TRANSITION_NAME, "small_img" + pos);
    ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(getActivity(), shareImageView, "small_img" + pos);
    getActivity().startActivity(intent, options.toBundle());
}

listener is called from onBindViewHolder of my adapter

  @Override
    public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) {
        if (holder instanceof ProductsViewHolder) {
            final PromoORProduct user = items.get(position);
            ProductsViewHolder userViewHolder = (ProductsViewHolder) holder;
                ViewCompat.setTransitionName(userViewHolder.imgSmall, "small_img"+position);
            holder.itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    productsItemClickListener.onProductItemClick(holder.getAdapterPosition(), user, ((ProductsViewHolder) holder).imgSmall);
                }
            });
            userViewHolder.bind(user, this);
        } else if (holder instanceof LoadingViewHolder) {
            LoadingViewHolder loadingViewHolder = (LoadingViewHolder) holder;
            loadingViewHolder.progressBar1.setIndeterminate(true);
        }
    }

in my called activity's onCreate

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_product_preview);
        imgSmall = findViewById(R.id.imgSmall2);
        Bundle extras = getIntent().getExtras();
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            getWindow().setSharedElementEnterTransition(TransitionInflater.from(this).inflateTransition(R.transition.shared_element_transaction));
            String imageTransitionName = extras.getString(SMALL_IMAGE_TRANSITION_NAME);
            imgSmall.setTransitionName(imageTransitionName);
        }

    }

the output is weird, the image is fading out in the fragment and popping in the called activity's imageview and when exit the same. Any ideas... Thanx a lot
