FirebaseRecyclerAdapter<Data, myViewHolder> adapter = new FirebaseRecyclerAdapter<Data, myViewHolder>(Data.class, R.layout.data_item, myViewHolder.class, databaseReference) {

First,
THANK YOU for AMAZING app !

its really great project.

since I tried to implement the same code on my project, i got error in FirebaseRecyclerAdapter line(172). I couldn't use populateViewHolder, because firebase already asked me to implement the methods, and once i implemet them, it asking me to return something or it will stay as error line.

may you help me please?

Thanks
`public void createRecycler() {

    FirebaseRecyclerAdapter<Events, myViewHolder> adapter = new FirebaseRecyclerAdapter<Events, myViewHolder>(Events.class, R.layout.data_item, myViewHolder.class, databaseReference) {


        @NonNull
        @Override
        public myViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
            return null;
        }

        @Override
        protected void onBindViewHolder(@NonNull myViewHolder holder, int position, @NonNull Events model) {

        }

        protected void populateViewHolder(myViewHolder myViewHolder, final Events data, final int i) {

            myViewHolder.setDate(data.getEventDate());
            myViewHolder.setType(data.getEventName());
      //      myViewHolder.setAmount(model.getmAmount());
            myViewHolder.setNote("note: " + data.getEventDesc());

            myViewHolder.view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // save the current ref and inputs to view inside update dialog

                    name = data.getEventName();
               //     amount = model.getmAmount();
                    desc = data.getEventDesc();
                    updateData();
                }
            });
        }

    };

    recyclerView.setAdapter(adapter);

}`
