Android RecyclerView布局错误

Question

我第一次显示孩子的布局时，我有一个recyclerview：

但是当我滚动到底部并回到顶部时它很好：

当我更改更大的布局时，我遇到同样的问题。

这是我的Adapter类（不考虑不同类型，这不是bug的来源，因为当我有一个ViewHolder类型时bug也存在）

 private class Adapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int TYPE_ALERTS = 0 ;
    private static final int TYPE_MOST_VIEWED = 1 ;



    @Override
    public RecyclerView.ViewHolder onCreateViewHolder (final ViewGroup parent, int viewType) {


        if (viewType == TYPE_ALERTS){

            View itemLayoutView =  LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.layout_item_alerts_home_home, null);

            ViewHolderAlerts viewHolderAlerts = new ViewHolderAlerts(itemLayoutView);

            itemLayoutView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick (View v) {


                        Intent intent = new Intent(activity, Activity_UpdateAlert.class);
                        intent.putExtra("alert", (AlertObj)listAllProducts.get(recyclerView.getChildAdapterPosition(v)));

                        startActivity(intent);

                }
            });

            return viewHolderAlerts;

        }else {

            View itemLayoutView =  LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.layout_item_product_grid__list_products_by_category, null);

            ViewHolder_Product_CatSearch viewHolder_product_catSearch = new ViewHolder_Product_CatSearch(itemLayoutView);

            itemLayoutView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick (View v) {


                    Intent intent = new Intent(activity, Activity_ProductDetails.class);
                    intent.putExtra("product", (Product)listAllProducts.get(recyclerView.getChildAdapterPosition(v)));

                    startActivity(intent);

                }
            });

            return  viewHolder_product_catSearch ;

        }
    }

    @Override
    public void onBindViewHolder (RecyclerView.ViewHolder holder, int position) {

        if (getItemViewType(position) == TYPE_ALERTS){

            ((ViewHolderAlerts)holder).textViewTitle.setText(((AlertObj)listAllProducts.get(position)).product.name);
            ((ViewHolderAlerts)holder).textViewPrice.setText(new DecimalFormat("###0.00")
                    .format(Double.valueOf(((AlertObj)listAllProducts.get(position)).product.price)) +
                    ((AlertObj)listAllProducts.get(position)).product.currency);

            Glide.with(activity.getApplicationContext())
                    .load(((AlertObj)listAllProducts.get(position)).product.imgUrl)
                            .error(R.drawable.picture_not_available)
                            .into(((ViewHolderAlerts) holder).imgView);

        }else {

            ((ViewHolder_Product_CatSearch)holder).textViewName.setText(((ProductMostViews)listAllProducts.get(position)).name);
            ((ViewHolder_Product_CatSearch)holder).textViewPrice.setText(new DecimalFormat("###0.00")
                    .format(Double.valueOf(((ProductMostViews)listAllProducts.get(position)).price)) +
                    ((ProductMostViews)listAllProducts.get(position)).currency);

            Glide.with(activity.getApplicationContext())
                    .load(((ProductMostViews)listAllProducts.get(position)).imgUrl)
                    .error(R.drawable.picture_not_available)
                    .into(((ViewHolder_Product_CatSearch) holder).imageViewProduct);


        }
    }

    @Override
    public int getItemViewType (int position) {

       return listAllProducts.get(position) instanceof AlertObj ? TYPE_ALERTS : TYPE_MOST_VIEWED ;
    }

    @Override
    public long getItemId (int position) {
        return listAllProducts.get(position) instanceof AlertObj ? TYPE_ALERTS : TYPE_MOST_VIEWED ;
    }

    @Override
    public int getItemCount () {
        return listAllProducts.size();
    }
}
