No adapter attached; skipping layout in fragment using firebase database

Question

I have gone through most of the topics related to it and couldn\'t find the proper solution.
I am getting an error \"E/RecyclerView: No adapter attached; skipping layout

Answer 1

Use Debugger to check if you are getting data from firebase database? Or try to Init your Adaptor in OnCreateview method and use notifydatasetchanged()

Answer 2

You have to set Adapter inside onCreateView then when new data arrives simply call adapter to notifyDataSetChaged

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v = inflater.inflate(R.layout.fragment_temp, container, false);
        youradapter = new TempAdapter(getContext(),new ArrayList<TempModel>());
        rcv = (RecyclerView) v.findViewById(R.id.recycle_template);          
        rcv.setAdapter();
        rcv.setLayoutManager(new GridLayoutManager(getContext(),3));
        rcv.setHasFixedSize(true);
        fireAdapter();
        return v;
    }

Then inside onDataChange callback

 @Override
 public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
     for (DataSnapshot postSnapshot : dataSnapshot.getChildren()){
         TempModel tempModel = postSnapshot.getValue(TempModel.class);
         tempData.add(tempModel);
       }
       TempAdapter  tempAdapter = new TempAdapter(getContext(),tempData);
       yourAdapter.setData(tempData);
        }

Then inside your TempAdapter class create setData function

public void setData(List<TempModel> list) {
   if (data != null) data.clear();
   if (data == null) data = new ArrayList<>();
   data.addAll(list);
   notifyDataSetChanged();

}
