---恢复内容开始---

1.首先在适配器定义一个枚举：

public enum ITEM_TYPE {
    ITEM1,
    ITEM2
}

2.然后在 OnCreatedViewHoler中这样写

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == ITEM_TYPE.ITEM1.ordinal()) {
        return new Item1ViewHolder(mLayoutInflater.inflate(R.layout.item1, parent, false));
    } else {
        return new Item2ViewHolder(mLayoutInflater.inflate(R.layout.item2, parent, false));
    }
}
3。在OnBind方法中 这样写：

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (holder instanceof Item1ViewHolder) {
        Glide.with(context).load(list.get(position).getThumbnail_pic_s()).into(((Item1ViewHolder) holder).image);
        ((Item1ViewHolder) holder).text.setText(list.get(position).getTitle());
    } else if (holder instanceof Item2ViewHolder) {
        Glide.with(context).load(list.get(position).getThumbnail_pic_s()).into(((Item2ViewHolder) holder).image1);
        Glide.with(context).load(list.get(position).getThumbnail_pic_s02()).into(((Item2ViewHolder) holder).image2);
        Glide.with(context).load(list.get(position).getThumbnail_pic_s03()).into(((Item2ViewHolder) holder).image3);
        ((Item2ViewHolder) holder).name.setText(list.get(position).getTitle());

    }
}

4.在getItemCout中这样写

@Override
public int getItemCount() {
    return list == null ? 0 :list.size();
}

5.在getitemType中这样写

return position % 2 == 0 ? ITEM_TYPE.ITEM1.ordinal() : ITEM_TYPE.ITEM2.ordinal();

6.然后下面这样写
//item2的viewholder

public static class Item2ViewHolder extends RecyclerView.ViewHolder {
   private final TextView name;
    private final ImageView image1;
    private final ImageView image2;
    private final ImageView image3;
    public Item2ViewHolder(View itemView) {
        super(itemView);
       name= (TextView) itemView.findViewById(R.id.name);
        image1 = (ImageView) itemView.findViewById(R.id.caritem_image1);
        image2 = (ImageView) itemView.findViewById(R.id.caritem_image2);
        image3 = (ImageView) itemView.findViewById(R.id.caritem_image3);
   itemView.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
           listeners.onclick(getAdapterPosition());
       }
   });
    }
}

//item1 的ViewHolder
public static class Item1ViewHolder extends RecyclerView.ViewHolder {
    TextView text;
    private final ImageView image;

    public Item1ViewHolder(View itemView) {
        super(itemView);
        text = (TextView) itemView.findViewById(R.id.text);
        image = (ImageView) itemView.findViewById(R.id.image);
      itemView.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              listeners.onclick(getAdapterPosition());
          }
      });
    }
}

//接口回调 ，用于监听条目

interface Listener{
    void  onclick(int position);

}
