如何使用自定义Recycler适配器创建封闭循环Recyclerview？ [英] how to create closed circular Recyclerview with custom Recycler adapter?

问题描述

这可能是重复的，但仍然没有正确的答案。
我提到了这个和< a href =https://stackoverflow.com/questions/28492359/circular-recyclerview>这个和这个

如链接中所述，我希望实施循环的回收查看，即

[查看1] - [查看2] ....- [查看N-1] - [查看N] - [查看1] .....等等

由于没有覆盖方法来获取View并在Recyclerview中获取物品，因此我
无法成功。

<请尽快帮助。谢谢！

我的回收商适配器代码

 公共类Horizo​​ntalRecyclerAdapter扩展了RecyclerView.Adapter< Horizo​​ntalRecyclerAdapter.ProductViewHolder> {
 
列表<产品>产品; 
 private Context mContext; 
 ImageLoader imageLoader; 
 
 
 Horizo​​ntalRecyclerAdapter（List< Product> products，Context mContext）{
 this.products = products; 
 this.mContext = mContext; 
 
} 
 
 @Override 
 public ProductViewHolder onCreateViewHolder（ViewGroup parent，int viewType）{
 View v = LayoutInflater.from（parent.getContext（） ）.inflate（R.layout.product_layout，parent，false）; 
返回新的ProductViewHolder（v）; 
} 
 
 @Override 
 public void onBindViewHolder（最终ProductViewHolder持有者，int位置）{
 
 imageLoader = SingletonRequestQueue.getInstance（mContext）.getImageLoader（ ）; 
 String URL = products.get（position）.getProductImageUrl（）; 
 holder.progressBar.setVisibility（View.VISIBLE）; 
 / *隐藏图像响应后的进度条* / 
 
 imageLoader.get（URL，new ImageLoader.ImageListener（）{
 @Override 
 public void onResponse （ImageLoader.ImageContainer响应，boolean isImmediate）{
 if（response！= null）{
 Bitmap bitmap = response.getBitmap（）; 
 if（bitmap！= null）{
 holder.progressBar.setVisibility（View.GONE）; 
} 
} 
} 
 @Override 
 public void onErrorResponse（VolleyError error）{} 
 }）; 
 holder.itemImage.setImageUrl（URL，imageLoader）; 
 holder.itemName.setText（products.get（position）.getProductName（））; 
 holder.itemPrice.setText（₹+ products.get（position）.getProductPrice（））; 
 holder.sellerLogo.setImageResource（products.get（position）.getProductSellerId（））; 
 
} 
 
 @Override 
 public int getItemCount（）{
 return products.size（）; 
} 
 
公共静态类ProductViewHolder扩展了RecyclerView.ViewHolder {
 
 NetworkImageView itemImage; 
 NetworkImageView sellerLogo; 
 TextView itemName; 
 TextView itemPrice; 
 ProgressBar progressBar; 
 
 
 public ProductViewHolder（查看itemView）{
 super（itemView）; 
 itemImage =（NetworkImageView）itemView.findViewById（R.id.product_image）; 
 sellerLogo =（NetworkImageView）itemView.findViewById（R.id.product_seller）;

解决方案

我深入了解并发现了一个有效的解决方案/ hack 这里。我测试了它，它运作良好。我正在关闭这个问题。谢谢！

this might be a possible duplicate , but proper answer is still not available. I referred to this and this and this

As stated in the links I wish to implement a recyclerview which is circular ie

[view 1]-[view 2]....-[view N-1]-[view N]-[view 1].....and so on

Since there are no override methods to get View and get Item in recyclerview , I am unable to succeed.

please help.Thanks in Advance!

my recycler adapter code

public class HorizontalRecyclerAdapter extends RecyclerView.Adapter<HorizontalRecyclerAdapter.ProductViewHolder> {

    List<Product> products;
    private Context mContext;
    ImageLoader imageLoader;


    HorizontalRecyclerAdapter(List<Product> products, Context mContext) {
        this.products = products;
        this.mContext = mContext;

    }

    @Override
    public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_layout, parent, false);
        return new ProductViewHolder(v);
    }

    @Override
    public void onBindViewHolder(final ProductViewHolder holder, int position) {

        imageLoader = SingletonRequestQueue.getInstance(mContext).getImageLoader();
        String URL = products.get(position).getProductImageUrl();
        holder.progressBar.setVisibility(View.VISIBLE);
        /* to hide the progress bar after image response */

        imageLoader.get(URL, new ImageLoader.ImageListener() {
            @Override
            public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
                if (response != null) {
                    Bitmap bitmap = response.getBitmap();
                    if (bitmap != null) {
                        holder.progressBar.setVisibility(View.GONE);
                    }
                }
            }
            @Override
            public void onErrorResponse(VolleyError error) {}
        });
        holder.itemImage.setImageUrl(URL, imageLoader);
        holder.itemName.setText(products.get(position).getProductName());
        holder.itemPrice.setText("₹ "+products.get(position).getProductPrice());
        holder.sellerLogo.setImageResource(products.get(position).getProductSellerId());

    }

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

    public static class ProductViewHolder extends RecyclerView.ViewHolder {

        NetworkImageView itemImage;
        NetworkImageView sellerLogo;
        TextView itemName;
        TextView itemPrice;
        ProgressBar progressBar;


        public ProductViewHolder(View itemView) {
            super(itemView);
            itemImage = (NetworkImageView) itemView.findViewById(R.id.product_image);
            sellerLogo = (NetworkImageView) itemView.findViewById(R.id.product_seller);
            itemName = (TextView) itemView.findViewById(R.id.product_name);
            itemPrice = (TextView) itemView.findViewById(R.id.product_price);
            progressBar = (ProgressBar)itemView.findViewById(R.id.network_image_progressbar);


        }
    }
}
