RecyclerView中item嵌套RecyclerView不显示问题

/**
* 重设item的高度
*/
private void resetRecyclerHeight(int type, int size) {
ViewGroup.LayoutParams layoutParams = item_recyclerview.getLayoutParams();
layoutParams.width = RecyclerView.LayoutParams.MATCH_PARENT;
if (type == 1) {
int coverWidth = (GlobleData.screenWidth - Uitl.dip2px(getContext(), 78)) / 4;
//单个图片高
int coverHeight = coverWidth * 9 / 16;
layoutParams.height = coverHeight * size;
} else {
layoutParams.height = ((GlobleData.screenWidth - Uitl.dip2px(getContext(), 100)) / 6) * size;
}

item_recyclerview.setLayoutParams(layoutParams);
}
