Answer 1

Sie haben einen verschachtelten Recycler Blick in Inneren Haupt Recycler Blick ins Inneren Haupt Layout hinzufügen anaother Recycler Ansicht und horizontal Recycler Elemente innerhalb dieser Recycler view.Create horizontal recyclerview innen Haupt recyclerview wie dies

public class SampleRecyclerView extends RecyclerView.Adapter { 

public SampleRecyclerView() { 
} 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.YOUR_MAIN_LAYOUT, parent, false); 
    return new SampleViewHolder(view); 
} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
    final SampleViewHolder viewHolder = (SampleViewHolder) holder; 

    //Update your Horizontal views here into adapter 
    notifyDataSetChanged(); 


} 


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

private class SampleViewHolder extends RecyclerView.ViewHolder{ 

    private YOUR_HORIZONTAL_ADAPTER mAdapter; 
    private RecyclerView.LayoutManager mLayoutManager; 

    public SampleViewHolder(View itemView) { 
     super(itemView); 

     mAdapter = new YOUR_HORIZONTAL_ADAPTER(mClassName, mMovieItems.get(Integer.toString(position))); 
     mLayoutManager=new LinearLayoutManager(mContext,LinearLayoutManager.HORIZONTAL,false); 

     YOUR_HORIZONTAL_RECYCLER_VIEW.setLayoutManager(mLayoutManager); 
     YOUR_HORIZONTAL_RECYCLER_VIEW.setAdapter(mAdapter); 
    } 

    } 
} 

EDIT dh erstellen: Ich habe einige Änderungen an Ihrem vorhandenen Recycler-Ansichtsadapter vorgenommen. Ihre verschachtelte Recycler-Ansicht sollte so aktualisiert werden.

public class Menu_List_Item extends RecyclerView.Adapter { 
private Activity activity; 
private ArrayList<Menu_List_Items_Pojo> menu_list_pojo_items; 


public Menu_List_Item(Activity activity, ArrayList<Menu_List_Items_Pojo> menu_list_pojo_items) { 
    this.activity = activity; 
    this.menu_list_pojo_items = menu_list_pojo_items; 
} 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.menu_list_item, parent, false); 
    return new Menu_List_Item_ViewHolder(view); 
} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
    Menu_List_Items_Pojo menulistitempojo = menu_list_pojo_items.get(position); 
    Menu_List_Item_ViewHolder viewholder = (Menu_List_Item_ViewHolder) holder; 
    viewholder.menu_name.setText(menulistitempojo.getMenu_name()); 

    //Call this method with different positions 
    viewholder.setDataToAdapter(position); 
    notifyDataSetChanged(); 
} 

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


public class Menu_List_Item_ViewHolder extends RecyclerView.ViewHolder { 
    @BindView(R.id.menu_name) 
    AppCompatTextView menu_name; 
    @BindView(R.id.menu_item_rv) 
    RecyclerView menu_item_rv; 
    ArrayList<Menu_Item_Adapter>itemsAdapter=new ArrayList<>(); 
    Menu_Item_Adapter meudap = new Menu_Item_Adapter(); 


    public Menu_List_Item_ViewHolder(View itemView) { 
     super(itemView); 
     ButterKnife.bind(this, itemView); 
     menu_item_rv.setLayoutManager(new LinearLayoutManager(itemView.getContext(), LinearLayoutManager.HORIZONTAL, false)); 
     menu_item_rv.setAdapter(menu_adapter); 
    } 

    //Change data value each time when onBindViewHolder is called 
    public void setDataToAdapter(int position) { 
     for(int i=0;i<menu_list_pojo_items.size();i++){ 
      meudap.setMenu_item_id(menu_list_pojo_items.get(position).getMenu_mid()); 
      meudap.setMenu_item_image(menu_list_pojo_items.get(position).getMenu_restaurant_image()); 
      meudap.setMenu_item_name(menu_list_pojo_items.get(position).getMenu_item()); 
      meudap.setMenu_item_price(menu_list_pojo_items.get(position).getMenu_price()); 
      itemsAdapter.add(meudap); 

     } 
     menu_adapter.add(itemsAdapter); 
    } 

    } 
}

Settyps in Ihrer Liste wie YourModel.setType (1)

list.add (YourModel);

public class MyAdapter extends RecyclerView.Adapter<ViewHolder> { 

private ArrayList<YourModel> list = new ArrayList<YourModel>(); 

    class HeaderViewHolder extends ViewHolder { 

    public HeaderViewHolder(View itemView){ 
     super(itemView); 

    } 
} 

class ItemsVideHolder extends ViewHolder { 
    public ItemsVideHolder(View itemView) { 
     super(itemView); 

    } 
} 

    @Override 
    public int getItemViewType(int position) { 

     int type = list.get(position).getType(); 

     //1 for header 
     if(type == 1){ 

     } 

     //2 for items 
     else if(type == 2){ 

     } 
     return position ; 
    } 

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

@Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View viewItem; 
     switch (viewType) { 
      case 1: 
       viewItem = LayoutInflater.from(parent.getContext()).inflate(R.layout.header_layout, parent, false); 
       ViewHolder vh = new HeaderViewHolder(viewItem); 
       return vh; 
      case 2: 
       viewItem = LayoutInflater.from(parent.getContext()).inflate(R.layout.items_layout, parent, false); 
       ViewHolder vh1 = new ItemsVideHolder(viewItem); 
       return vh1; 

     } 
     return null; 
    } 

    @Override 
    public void onBindViewHolder(final ViewHolder holder, final int position) { 
     switch (holder.getItemViewType()) { 
      case 0: 
       HeaderViewHolder viewHolder0 = (HeaderViewHolder) holder; 
       break; 

      case 2: 
       ItemsVideHolder viewHolder2 = (ItemsVideHolder) holder; 
       break; 
     } 
    } 
}
