onCreateViewHolder始终返回-1
onCreateViewHolder始终返回-1

为什么我的onCreateViewHolder位置总是-1？我就是想不通为什么
viewHolder.getAdapterPosition()始终为-1
@NonNull
@Override
public AdapterAllComments.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int a) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.model_rv_allcomments_container, viewGroup, false);
ViewHolder viewHolder = new ViewHolder(view);
for(int i = 0; i<mDepth.get(viewHolder.getAdapterPosition()); i++) {
View divider = LayoutInflater.from(viewHolder.itemView.getContext())
.inflate(R.layout.groupie_section_item_divider, viewHolder.viewHolderLayout, false);
viewHolder.viewHolderLayout.addView(divider);
}
return viewHolder;
}错误：
