我的应用程序总是崩溃,我尝试使用RecyclerView访问显示cardview的片段。

这是我的片段

public class Fragmentone extends Fragment {
    private RecyclerView recyclerView;
    private List<TestBean> listItem;
    private RecyclerAdapter adapter;


    public Fragmentone() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_fragmentone, container, false);

        recyclerView = (RecyclerView) view.findViewById(R.id.recyclerview);
        initData();

        adapter = new RecyclerAdapter(listItem,getActivity());
        LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
        recyclerView.setHasFixedSize(true);
        layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(layoutManager);
        recyclerView.setAdapter(adapter);
        return view;
    }

    private void initData() {
        listItem = new ArrayList<>();

        listItem.add(new TestBean("佛山傻逼酒店","二月17号","二月18号","600","已付款"));

    }

}

这是我的适配器

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ListViewHolder> {
    private List<TestBean> listitem;
    private Context context;

    public RecyclerAdapter(List<TestBean> listitem, Context context) {

        this.listitem = listitem;
        this.context = context;
    }

    @Override
    public ListViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(context).inflate(R.layout.card_item, viewGroup, false);
        ListViewHolder listViewHolder = new ListViewHolder(v);
        return listViewHolder;
    }

    @Override
    public void onBindViewHolder(ListViewHolder holder, int i) {
        holder.tv_roomfee.setText(listitem.get(i).getRoomfee());
        holder.tv_hotelname.setText(listitem.get(i).getHotelname());
        holder.tv_liststate.setText(listitem.get(i).getListstate());
        holder.tv_checkindate.setText(listitem.get(i).getCheckindate());
        holder.tv_lastcheckindate.setText(listitem.get(i).getLastcheckindate());

        holder.btn_paynow.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });
        holder.btn_cancellist.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });
    }


    @Override
    public int getItemCount() {
        return listitem.size();
    }

    public class ListViewHolder extends RecyclerView.ViewHolder {

        CardView id_cardview;

        TextView tv_roomfee;
        TextView tv_liststate;
        TextView tv_hotelname;
        TextView tv_checkindate;
        TextView tv_lastcheckindate;

        Button btn_paynow;
        Button btn_cancellist;

        public ListViewHolder(final View itemView) {
            super(itemView);
            id_cardview = (CardView) itemView.findViewById(R.id.id_cardview);
            tv_roomfee = (TextView) itemView.findViewById(R.id.tv_roomfee);
            tv_liststate = (TextView) itemView.findViewById(R.id.tv_liststate);
            tv_hotelname = (TextView) itemView.findViewById(R.id.tv_hotelname);
            tv_checkindate = (TextView) itemView.findViewById(R.id.tv_checkindate);
            tv_lastcheckindate = (TextView) itemView.findViewById(R.id.tv_lastcheckindate);

            btn_paynow.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                }
            });
            btn_cancellist.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                }
            });
        }
    }
}

这是我的cardview的xml

        </RelativeLayout>


    </android.support.v7.widget.CardView>

</RelativeLayout>

当我注意到

 LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
 recyclerView.setLayoutManager(layoutManager);

它没有崩溃,但是cardview确实如此
