【Android学习笔记】RecycleView 绑定了Adapter的item明明设置了match_parent却不起作用

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//        View view = View.inflate(parent.getContext(), R.layout.item_recharge, null);
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_recharge, parent, false);
return new IncomeViewHodler(view, parent.getContext());
}
