打开包含RecyclerView的片段后，“内存”迅速上升。当上下几次sc上，“记忆”继续上升，然后显示OOM和Force Close。 enter image description here

以下是RecyclerView截图：

以下是我的适配器代码：

我只使用一个RecyclerView整页并在第一个项目中嵌套GridView; 

public class CategoryPagerItemAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {


//热门分类
public static final int VIEW_TYPE_HOT_SUB_CATE = 1;
//banner+商品横滑推荐
public static final int VIEW_TYPE_PROMOTION_LIST = 2;
public static final int VIEW_TYPE_PROMOTION_LIST_LABEL = 3;
//商品集合
public static final int VIEW_TYPE_GOODS_LIST = 4;
//商品集合标签
public static final int VIEW_TYPE_GOODS_LIST_LABEL = 5;
//加载更多
public static final int VIEW_TYPE_GOODS_LIST_MORE = 6;


public static final int COUNT_HOT_SUB_CATE=1;
public static final int COUNT_HOT_GOODS_LIST_LABEL=1;
public static final int COUNT_HOT_GOODS_LIST_MORE=1;

private String mTagId;//TabLayout的title对应的tagid
private String mTitleName;//TabLayout的title对应的name
private int mIndex = -1;//ViewPager的index
private int mLevel = 1;//级别分类

//相关的banner+横滑商品

private int mRelatedTagSize, mGoodsListSize;

private OnGoodsItemClickListener mOnGoodsItemClickListener;

public CategoryPagerItemAdapter(Context context, String tagId, String titleName, int index) {
    mTagId = tagId;
    mTitleName = titleName;
    mIndex = index;
    mContext = context;
}

    mHotSubCategoryListEntityList = hotSubCategoryListEntityList;
    mRelatedTagListEntityList = relatedTagListEntityList;
    mGoodListEntityList = goodListEntityList;
    mRelatedTagSize = mRelatedTagListEntityList == null ? 0 : mRelatedTagListEntityList.size();
    mGoodsListSize = mGoodListEntityList == null ? 0 : mGoodListEntityList.size();
    mLevel = level;
