错误写法：
@Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(mContext).inflate(R.layout.item_complain_list, null, false); view.setOnClickListener(this); return new ViewHolder(view); }
正确写法：
@Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(mContext).inflate(R.layout.item_complain_list, parent, false); view.setOnClickListener(this); return new ViewHolder(view); }
此处传入的parent即为item的根布局
