Question

我的rV有小问题。我正在一个项目中，我不必在RecyclerView上显示所有位置，这是我的问题，如何使它们不可见。我正在尝试VIEW.GONE，但它在布局之间留出间隔。就是这样

holder.relativeLayoutPartnera.setVisibility（View.GONE）; 得分也一样。

有什么想法吗？

public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {
    PartnersModel currentItem = partnerList.get(position);

    holder.wariantNagrody.setOrientation(LinearLayout.VERTICAL);
    holder.partnerName.setText(currentItem.getName());

    if(currentItem.getIlosc_pkt().equals("") || currentItem.getIlosc_pkt().isEmpty()){
        holder.textView_ownedPoints.setText("0");
    }else{
        holder.textView_ownedPoints.setText(currentItem.getIlosc_pkt());
    }

    nid.clear();
    descOfPromotion.clear();
    pointsForPromotion.clear();

    for(int i=0; i < currentItem.listOfReward.size(); i++) {
        if (currentItem.listOfReward.get(i).getBid().equals(currentItem.bid)) {
            if((Integer.parseInt(currentItem.listOfReward.get(i).getPoints()) <= Integer.parseInt(String.valueOf(holder.textView_ownedPoints.getText())))){
                if(!nid.contains(currentItem.listOfReward.get(i).getBid())){
                    nid.add(currentItem.listOfReward.get(i).getBid());
                    descOfPromotion.add(currentItem.listOfReward.get(i).getName());
                    pointsForPromotion.add(currentItem.listOfReward.get(i).getPoints());
                }
            }
        }
    }

    if(nid.size() > 0){
        Log.v("parser", "IS OKEY.");
    } else{
        Log.v("parser", "ERROR. DO NOT DISPLAY THIS POSITION");
        holder.params.height = 0;
        holder.params.width = 0;
        holder.params.setMargins(0,0,0,0);
        holder.layout.setLayoutParams(holder.params);
    }

        Picasso.get()
                .load(StartActivity.partners_layout_url + currentItem.getPic())
                .placeholder(R.drawable.error_image)
                .fit()
                .transform(new picasso_rounded_corners(50, 0, picasso_rounded_corners.CornerType.TOP))
                .into(holder.partnerLogo);

        if (currentItem.getIlosc_pkt().isEmpty() || Integer.parseInt(currentItem.getIlosc_pkt()) == 0) {
            holder.textView_ownedPoints.setText("0");

        } else {
            holder.textView_ownedPoints.setText(currentItem.getIlosc_pkt());
        }

        holder.wariantNagrody.removeAllViews();


    for (int i = 0; i < descOfPromotion.size(); i++) {
            View child1 = LayoutInflater.from(mContext).inflate(R.layout.view_layout_extended_description_partner, null);
            TextView promotionPoints = child1.findViewById(R.id.textView_viewLayoutExtendedDiscPartner_points);
            TextView promotionDesc = child1.findViewById(R.id.textView_viewLayoutExtendedDiscPartner_desc);
            promotionPoints.setText(pointsForPromotion.get(i));
            promotionDesc.setText(descOfPromotion.get(i));
            holder.wariantNagrody.addView(child1);
    }
}

如何隐藏不需要的物品？
