回收站的viewholder內

Question

喜的朋友，請幫助我，我用它有一個標題我所在的地方填充使用JSON數據我的問題是另外一個水平的循環視圖循環認爲，在水平回收視圖我得到只有最後一個值請在下面的代碼中找到。

這裏的佈局，需要

Menu_Item_List.java

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 

    <android.support.v7.widget.AppCompatTextView

     android:background="@drawable/cater_bg" 
     android:padding="4dp" 
     android:text="Break Fast"

Answer 1

你必須創建，即主要佈局內回收主視圖內嵌套回收視圖中添加主recyclerview內anaother回收視圖和回收view.Create水平recyclerview水平內回收的項目，如本

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); 
    } 

    } 
} 

編輯：我對現有的回收視圖適配器進行了一些更改。您的嵌套回收視圖應該像這樣更新。在你的名單像YourModel.setType（1）

list.add（YourModel）

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); 
    } 

    } 
}

集類型;

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; 
     } 
    } 
}
