android - 对于包含自己的 recyclerView 的不同 xml 布局，我可以拥有多个 RecyclerViewAdapter 类吗？

Question

我已经有一个 RecyclerViewAdapter 类，现在我想要打开另一个 Activity ，点击以前的 recyclerView 的项目，它有自己的 recyclerView。但是当我创建另一个 RecyclerViewAdapter 和 ViewHolder 时，它向我显示了 onCreateViewHolder 方法与 First Adapter 类的方法冲突的错误。我怎么可能有多个 recyclerViewAdapter ......我希望我能解释我想要的。任何帮助将不胜感激。

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {

    private Context mContext;
    private List<Main> mData;

    public RecyclerViewAdapter(Context mContext, List<Main> mData) {
        this.mContext = mContext;
        this.mData = mData;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view;
        LayoutInflater mInflator = LayoutInflater.from(mContext);
        view = mInflator.inflate(R.layout.single_view, parent, false);
        return new MyViewHolder(view);
    }

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

        holder.textView.setText(mData.get(position).getTitle());
        holder.imageView.setImageResource(mData.get(position).getThumbnail());
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                switch (mData.get(position).getTitle()){
                    case "Grocery & Staples":
                        //Toast.makeText(mContext, "1", Toast.LENGTH_SHORT).show();
                        Intent intent = new Intent(mContext, GroceryStaples.class);
                        mContext.startActivity(intent);
                        break;
                    case "Personal Care":
                        Toast.makeText(mContext, "2", Toast.LENGTH_SHORT).show();
                        break;
                    case "Household Items":
                        Toast.makeText(mContext, "3", Toast.LENGTH_SHORT).show();
                        break;
                    case "Beverages":
                        Toast.makeText(mContext, "4", Toast.LENGTH_SHORT).show();
                        break;
                    case "Breakfast & Dairy":
                        Toast.makeText(mContext, "5", Toast.LENGTH_SHORT).show();
                        break;
                    case "Instant Food":
                        Toast.makeText(mContext, "6", Toast.LENGTH_SHORT).show();
                        break;
                    case "Fruits & Vegetables":
                        Toast.makeText(mContext, "7", Toast.LENGTH_SHORT).show();
                        break;
                    default:
                        Toast.makeText(mContext, "NO", Toast.LENGTH_SHORT).show();
                        break;
                }
            }
        });

    }

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

    @Override
    public int getItemViewType(int position) {
        return super.getItemViewType(position);
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {

        //Main Activity
        ImageView imageView;
        TextView textView;        

        public MyViewHolder(@NonNull View itemView) {
            super(itemView);
            mContext = itemView.getContext();
            //Main Activity
            imageView = itemView.findViewById(R.id.imageView);
            textView = itemView.findViewById(R.id.textView);


        }

    }

}

新适配器:

public class RvAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {

    private Context mContext;
    private List<Main> mData;

    public RvAdapter(Context mContext, List<Main> mData){
        this.mContext = mContext;
        this.mData = mData;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view;
        LayoutInflater mInflator = LayoutInflater.from(mContext);
        view = mInflator.inflate(R.layout.rv_item_click, parent, false);
        return null
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerViewAdapter.MyViewHolder holder, int position) {

    }


    @Override
    public int getItemCount() {
        return 0;
    }

    public class ViewHolder extends RecyclerView.ViewHolder{

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
        }
    }
}

在您的 NewAdapter.java代替:

public class RvAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>

和

public class RvAdapter extends RecyclerView.Adapter<RvAdapter.ViewHolder>

并替换:

public void onBindViewHolder(@NonNull RecyclerViewAdapter.MyViewHolder holder, int position)

和

public void onBindViewHolder(@NonNull RvAdapter.ViewHolder holder, int position)
