i am trying to display data from a textview on an activity onto a recycler view on a fragment. I have an adapter class to implement the adapter methods. however when i click the fragment the app closes and the .count method remains unable to be resolved. the code is attached below;
public class NotesXFragment extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View noteview = inflater.inflate(R.layout.fragment_notes, container, false);
note_fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(getActivity(), AddNote.class));
}
});
RecyclerView recyclerView = (RecyclerView) noteview.findViewById(R.id.note_rv);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
// notesDbAdapter = new NotesDbAdapter(getActivity(),notes);
// recyclerView.setAdapter(notesDbAdapter);
notecount = Note.count(Note.class);
if(notecount>=0){
notes = Note.listAll(Note.class);
notesDbAdapter = new NotesDbAdapter(getActivity(),notes);
recyclerView.setAdapter(notesDbAdapter);
}
return noteview }
}
Please check if you're correctly importing the Note class. Moreover, you can try to get the count using the SugarRecord class, i find it to work better than using the normal classes.
notecount = SugarRecord.count(Note.class);
Please check if you're using the most recent version of the library.
Additionally, whenever you update your schema, please increment your DB version in your AndroidManifest.xml
file.
