recyclerview 点击事件

给条目设置个id

private OnItemListener onItemListener;    public interface OnItemListener{        public void  onItemClick(FenleiZuoBean.DatasBean.ClassListBean bean);    }    public void setonItemListen(OnItemListener onItemListener){        this.onItemListener = onItemListener;    }

viewHolder.ll.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                if(onItemListener != null){                    onItemListener.onItemClick(list.get(position));                }            }        });
