Java 如何在Android上实现父子循环视图

你能给我一些关于亲子循环的参考资料吗？我已经成功地进行了

parent Recycleview

，但当我从

parent

单击项目时，我坚持通过

child Recycleview

注：我正在使用虚拟数据

这是我想要创建的recyclerview的示例：

这是我的密码

RecycleParentAdapter.java

public class RecycleParentMenuAdapter extends RecyclerView.Adapter<RecycleParentMenuAdapter.ViewHolder>{

    private ArrayList<Store> mData;
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;

        View view = mInflater.from(viewGroup.getContext()).inflate(R.layout.list_store_lists, viewGroup, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.storeName.setText(mData.get(position).getName());
//        holder.storeImage.setImageURI(mData.get(position).getImage());
    }

    public int getItemCount() {
        return (mData != null) ? mData.size() : 0;
    }

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

感谢您的帮助

您需要在RecycleParentAdapter.java的onBindViewHolder中填充RecycleChildAdapter.java 比如：

以及：

在父回收器项目布局中创建一个回收器视图，并从父回收器的onBind方法进行设置recycler@VipulChauhan对不起，先生，您能详细解释一下吗。因为我真的很困惑。谢谢
