RecyclerView显示不同的类型的item

1 .复写RecyclerView的Adapter中的getItemViewType 方法

@Override
public int getItemViewType(int position) {
    if (position == 0) {
        return ITEM_TYEP_2;  //左边的

    } else {
        return ITEM_TYEP_1;  //更多
    }

}

定义要显示的item类型常量

public static final int ITEM_TYEP_1 = 1;  //
public static final int ITEM_TYEP_2 = 2;

2.在onCreateViewHolder 方法中 对item显示数据的类型进行判断 根据item 的类型返回不同的ViewHolder

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    if (viewType == ITEM_TYEP_1) {
        return new MyViewHolder(layoutInflater.inflate(R.layout.item_home_more, parent, false));

    } else {
        return new LeftContentViewHolder(layoutInflater.inflate(R.layout.item_home_left, parent, false));
    }

}

3.现在在不同的ViewHolder 中获取控件

class MyViewHolder extends RecyclerView.ViewHolder {
    TvImageView more_item_top;
    TvImageView more_item_bottom;

    public MyViewHolder(View itemView) {
        super(itemView);
        more_item_top = (TvImageView) itemView.findViewById(R.id.iv_home_more_top);
        more_item_bottom = (TvImageView) itemView.findViewById(R.id.iv_home_more_bottom);
    }
}

/**
 * 左边的ViewHolder
 */
class LeftContentViewHolder extends RecyclerView.ViewHolder {
    LinearLayout ll_left;

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

        ll_left = (LinearLayout) itemView.findViewById(R.id.ll_home_left);
    }
}

4 . 在onBindViewHolder 中判断ViewHolder 的类型,进行视图和数据的绑定

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (holder instanceof MyViewHolder) {
        ((MyViewHolder) holder).more_item_top.setImageResource(mMoreImgList.get(position));
        ((MyViewHolder) holder).more_item_bottom.setImageResource(mMoreImgList.get(position));

    } else {

      //  ((LeftContentViewHolder) holder).letf_imageView.setImageResource(R.drawable.theme1_main_02);
    }

}
