RecycleView的多布局

---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

@Overridepublic 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：

@Overridepublic 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

@Overridepublic 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ViewHolderpublic 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);

}
