Error in BD/list

Question

I was following a tutorial on how to CRUD, but an error appeared to me (in the tutorial is ok)

How do I fix it?

    lista = (ListView) findViewById(R.id.lista_Madicamentos);
    registerForContextMenu(lista);


    lista.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapter, View view, int position, long id) {
            Medicamentos medicamentoEscolhido = (Medicamentos) adapter.getItemIdAtPosition(position);

            Intent i = new Intent(CadastroActivity.this, FormularioActivity.class);
            i.putExtra("medicamento-escolhido", medicamentoEscolhido);
        }
    });

    lista.setOnLongClickListener(new AdapterView.OnItemLongClickListener() { //clique longo, para selecionar a linha
        @Override
        public boolean onItemLongClick(AdapterView<?> adapter, View view, int position, long id) {
            medicamento = (Medicamentos)adapter.getItemAtPosition(position);
            return false;
        }
    });

About the error: On the line

Medicamentos medicamentoEscolhido = (Medicamentos) adapter.getItemIdAtPosition(position);

He makes the mistake:

Inconvertible types; cannot cast 'long' to 'com.example.(...).Medicamentos'

And suggests that medicationSchool is the long type.

How do I fix it? Thank you

Answer 1

Method name spelled wrong.

Shouldn’t getItemIdAtPosition() and yesgetItemAtPosition().

getItemIdAtPosition() returns a long, which is the item ID.

getItemAtPosition() returns the item, which can be converted (cast) for Medicamentos.
