            </LinearLayout>



        enter code here
        </android.support.v7.widget.CardView>


    </LinearLayout>

This is the recycler's Adapter code
  @Override
    public void onBindViewHolder(ArticleViewHolder holder, int position) {
        holder.mAvatarView.setText(mArticles.get(position).getmAvatarInitial());
        holder.mAvatarNameView.setText(mArticles.get(position).getmAvatarName());
        holder.mAvatarSubView.setText(mArticles.get(position).getmAvatarSub());
        mRowIndex++;
        if (position == 0) {

            holder.horizontalList.setLayoutManager(new LinearLayoutManager(holder.context, LinearLayoutManager.HORIZONTAL, false));
            holder.horizontalAdapter = new SectionRVAdapter(holder.context);
            holder.horizontalList.setAdapter(holder.horizontalAdapter);
            holder.horizontalAdapter.setDataset(holder.sections);

        }

        String imageUrl = mArticles.get(position).getmImageURL();

        Picasso.with(mContext)
                .load(imageUrl)
                .placeholder(R.drawable.placeholder)
                .error(R.drawable.error_img)
                .into(holder.mImageView);
        holder.mTheTitleView.setText(mArticles.get(position).getmTheTitle());

        holder.mTheThreeLinesView.setText(mArticles.get(position).getmTheThreeLines());


    }

现在我想在垂直回收者视图上看一个水平回收者视图。但目前水平回收者视图在每5次卡片视图后重复出现。

我正在检查我的onBindViewHolder方法中的position是否等于0，但仍然为什么会多次创建它？

我希望我明白我的问题。

Answer 1

holder.setIsRecyclable（假）;

在public void onBindViewHolder中添加此行（ArticleViewHolder holder，int position）{}

我希望这会对你有所帮助

在垂直的回收者veiw顶部的水平的回收者视图
