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

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
