Android RecyclerView: Kein Adapter angeschlossen; Layout überspringen

Question

Jetzt habe ich Raster zu Recyclerview Grid geändert, so denke ich, alles wird in Ordnung sein, aber nein, ich hatte noch ein Problem. Ich habe nach denselben Fragen gesucht, versuche mein eigenes Problem zu lösen, aber nein, alles hilft mir nicht.

Log:{ 

RecyclerView: No adapter attached; skipping layout 

} 

Also das ist mein Code:

Database database; 
int mId; 
boolean isFabOpen; 
RecyclerViewGridODAdapter recyclerViewGridODAdapter; 
AlertDialog.Builder myDialog; 
int[]Ids; 
GridAutofitLayoutManager layoutManager; 
private Animation fab_open,fab_close,rotate_forward,rotate_backward; 
List<OneDayTD> oneDayList; 
private static final String TAG = "MyLog"; 
// TODO: Rename parameter arguments, choose names that match 
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER 
private static final String ARG_PARAM1 = "param1"; 
private static final String ARG_PARAM2 = "param2"; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    if (getArguments() != null) { 
     mParam1 = getArguments().getString(ARG_PARAM1); 
     mParam2 = getArguments().getString(ARG_PARAM2); 
    } 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container3, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    View v =inflater.inflate(R.layout.fragment_one_day_tasks,container3,false);

Put

recyclerViewGridODAdapter =new RecyclerViewGridODAdapter(oneDayList); 

in onCreateView() statt onCreate() wie diese.

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container3, 
         Bundle savedInstanceState) { 
..... 
    if(mId>=1) { 
      oneDayList = database.getOneDayList(1); 
     } 
    recyclerViewGridODAdapter =new RecyclerViewGridODAdapter(oneDayList); 
... 
} 

Der Fehler ist, weil oneDayList leer ist, wenn Sie Ihren Adapter erstellen. Sie sollten Ihren Adapter entweder in onCreateView() (wie oben gezeigt) erstellen oder Ihren Adapter aktualisieren, nachdem Sie Werte in oneDayList erhalten haben.
