Question

早上好，我在尝试将Recyclerview与另一个Recyclerview链接时遇到问题，我的意思是在我的活动中，第一个recyclerview在我的活动中，而该活动又为第二个Recyclerview（在LinearLayout中）填充，因为一旦该recyclerview被具有ImageView和TextView的另一个布局填充，问题是由于该应用程序停止，我不能使用两个recycler视图，但是如果我以相同的方式分别使用该布局，则我知道如果我解释一下，我有3种布局：

问题在于，由于该应用程序停止运行，因此我无法同时使用这两个回收站视图，但是如果我分别使用布局（如果它们以相同的方式工作），我不知道自己是否解释了，我有3种布局，一种在包含recyclerview的活动中，包含第二个recyclerview和texview的元素的容器，最后是包含imageView和texView的layout portraitLayout，如果我仅使用活动的布局，则呈现第二个很好，但是没有任何图像，如果我删除活动的布局，而将第二个保留为第三个，则将使用各自的图像进行渲染。

我有2个适配器：

AdapterPortrait：

`public class Adapter_Portrait extends RecyclerView.Adapter<Adapter_Portrait.ViewHolder> {
    private List<Portrait> portraits;
    private int layout;
    private OnItemClickListener listener;
    private Context context;


    public Adapter_Portrait(List<Portrait> portraits, int layout, OnItemClickListener listener) {
        this.portraits = portraits;
        this.layout = layout;
        this.listener = listener;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v= LayoutInflater.from(parent.getContext()).inflate(this.layout,parent,false);
        ViewHolder vh=new ViewHolder(v);
        context=parent.getContext();
        return vh;
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.bind(portraits.get(position),this.listener);
    }

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

    public class ViewHolder extends RecyclerView.ViewHolder{
        ImageView imageView;
        TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            this.imageView = itemView.findViewById(R.id.imagePortrait);
            this.textView = itemView.findViewById(R.id.textNamePortrait);

        }


        public void bind(final Portrait portrait, final OnItemClickListener listener){
            this.textView.setText(portrait.getName_portrait());
            Picasso.with(context).load(portrait.getImagePortrait()).fit().into(imageView);

            itemView.setOnClickListener(new View.OnClickListener(){

                @Override
                public void onClick(View view) {
                    listener.onItemClick(portrait, getAdapterPosition());
                }
            });

        }
    }

    public interface OnItemClickListener{
        void onItemClick(Portrait portrait, int position);
    }
}`

AdapterList_Pieces：

`public class AdapterList_Pieces extends 
 RecyclerView.Adapter<AdapterList_Pieces.ViewHolder> {

    private List<Artist> artists;
    private int layout;
    private OnItemClickListener listener;
    private Context context;

    public AdapterList_Pieces(List<Artist> artists, int layout, OnItemClickListener listener) {
        this.artists = artists;
        this.layout = layout;
        this.listener = listener;
    }

    public class ViewHolder extends RecyclerView.ViewHolder{
        RecyclerView recyclerView;
        TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            this.recyclerView = itemView.findViewById(R.id.RecyclerViewPieces);
            this.textView = itemView.findViewById(R.id.textViewPieces);
        }


        public void bind(final Artist artist, final OnItemClickListener listener){
            this.textView.setText(artist.getName_artist());


            itemView.setOnClickListener(new View.OnClickListener(){

                @Override
                public void onClick(View view) {
                    listener.onItemClick(artist, getAdapterPosition());
                }
            });

        }
    }


    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v= LayoutInflater.from(parent.getContext()).inflate(this.layout,parent,false);
        ViewHolder vh=new ViewHolder(v);
        context=parent.getContext();
        return vh;
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.bind(artists.get(position),this.listener);

    }

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

    public interface OnItemClickListener{
        void onItemClick(Artist artist, int position);
    }

}`

我的活动是：

public class PiecesActivity extends AppCompatActivity {
    List<Artist> artists;
    List<Portrait> portraits;
    RecyclerView recyclerView;
    RecyclerView recyclerViewPiece;
    RecyclerView.Adapter rAdapter;
    RecyclerView.LayoutManager layoutManagerPiece;
    RecyclerView.Adapter AdapterPiece;
    RecyclerView.LayoutManager layoutManager;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.portraitcontenetorslayout);

        recyclerView= findViewById(R.id.recyclerViewListPieces);
        recyclerViewPiece= findViewById(R.id.RecyclerViewPieces);
        artists= ConsultingInformation.getArtist();
        portraits= ConsultingInformation.getPortrait();
        layoutManager = new LinearLayoutManager(this);
        layoutManagerPiece =   new LinearLayoutManager(this);

        rAdapter= new Adapter_Portrait(portraits,R.layout.portraitlayout, new Adapter_Portrait.OnItemClickListener(){

            @Override
            public void onItemClick(Portrait portrait, int position) {
                Toast.makeText(PiecesActivity.this, "This piece is "+ portraits.get(position).getName_portrait(), Toast.LENGTH_LONG).show();
            }
        });

        recyclerViewPiece.setHasFixedSize(true);
        recyclerViewPiece.setItemAnimator(new DefaultItemAnimator());
        recyclerViewPiece.setLayoutManager(layoutManagerPiece);
        recyclerViewPiece.setAdapter(rAdapter);

        AdapterPiece= new AdapterList_Pieces(artists,R.layout.portraitcontenetorslayout, new AdapterList_Pieces.OnItemClickListener(){
            @Override
                public void onItemClick(Artist artist, int positionArt) {
                    Toast.makeText(PiecesActivity.this, "This list of pieces is "+ artists.get(positionArt).getName_artist(), Toast.LENGTH_LONG).show();
                }
        });

        recyclerView.setHasFixedSize(true);
        recyclerView.setItemAnimator(new DefaultItemAnimator());
        recyclerView.setLayoutManager(layoutManager);
        recyclerView.setAdapter(AdapterPiece);

    }

我已经读过，不可能在另一个列表中放置一个可下载列表，但是对于我的情况，我没有一个不稳定的方法，即两个对象列表在另一个列表中。

我的布局以防万一。

PortraitLayout：

Recyclerview中的LinearLayout，另一个RecyclerView中的LinearLayout
