Problem recovering firebase values for list

Question

I am making a list, and on this list I pull up the following information id, idPostagem, description, usergroup and photoUsuario.

However to popular(add) data to this list I am using the following code snippet within an Activity:

        itensSalvosRef = ConfiguracaoFirebase.getFirebase().child("itens-salvos").child(idUsuarioLogado);        

        @Override
        protected void onStart() {
            super.onStart();
            listarItensSalvos();
        }    

        private void listarItensSalvos() {

            valueEventListener = itensSalvosRef.addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {

                    listaItemSalvo.clear();

                    for (DataSnapshot ds : dataSnapshot.getChildren()) {

                        listaItemSalvo.add(ds.getValue(ItemSalvo.class));

                    }

                    Collections.reverse(listaItemSalvo);
                    itensSalvosAdapter.notifyDataSetChanged();
                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });

        }

Firebase structure:

The idea is to recover all values, but it only recovers the name Suario, as shown in the photo below:

What I’m doing wrong to the popular (add values) to that list?

Answer 1

The names of your property class listItemSalvo are totally different from your firebase database, only the field userName is correct, so only it is coming filled in...

Your target list class looks like this:

descricao
fotoPostagem
id
nomeUsuario

But the right thing, I believe, is that it should be

feedDescricao
feedFoto
feedId
nomeUsuario

Always try to create your classes giving names to the properties equal the fields of the bank, that is, always try to mirror the bank in your class, this facilitates the understanding and also leaves everything more practical.
