How do I take a Long value in an Edittext and insert it into Firebase?(Android Studio)

Question

I need to take a long value and insert it into Firebase and then show it in a Listview. I created a Pessoa class and with the other attributes I was able to insert and show it in a good one. Only the Long attribute I can’t, it’s a mistake. I am receiving the values by Plain Text(Edittext) My class Person is like this:

`public class Pessoa {
private String latitude,longitude;
private String uid;
private String cnpj;
private String razao;
private Long  codigo;

public Pessoa() {
}...



public Long getCodigo() {

    return codigo;
}

public void setCodigo(Long codigo) {
    this.codigo = codigo;
}

@Override
public String toString() {
    return
            "Código Cliente:" +codigo +"\n"+
            "CNPJ:" +cnpj +"\n"+
            "Razão Social:" +razao +"\n"+
            "Latitude:" +latitude +"\n"+
            "Longitude:" +longitude +"\n"

    ;
}

} ` Here’s my Mainactivity, you can see I’m trying to get the Long id and put it in Firebase and the error already appears on the line where I insert Long:

The code follows to return in a Listview but it is not necessary to show the rest, the same error is already present in that part of the code

public class MainActivity2 extends AppCompatActivity {
private EditText cnpj1,razao1, latitude1, longitude1,codigo1;
private ListView list;
private Button botao2;
private DatabaseReference referencia = FirebaseDatabase.getInstance().getReference();

private List<Pessoa> listPessoa = new ArrayList<Pessoa>();
private ArrayAdapter<Pessoa> arrayAdapterPessoa;
Pessoa pessoaSelecionada;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    codigo1 = findViewById(R.id.CodigoCliente);
    cnpj1 = findViewById(R.id.CnpjCliente);
    razao1 = findViewById(R.id.RazaoCliente);
    latitude1 = findViewById(R.id.LatitudeCliente);
    longitude1 = findViewById(R.id.LongitutudeCliente);
    botao2 = findViewById(R.id.buttonCliente);
    list = findViewById(R.id.ListaCliente);



    botao2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Pessoa p = new Pessoa();
            p.setUid(UUID.randomUUID().toString());

            p.setCnpj(cnpj1.getText().toString());
            p.setRazao(razao1.getText().toString());
            p.setLatitude(latitude1.getText().toString());
            p.setLongitude(longitude1.getText().toString());
            p.setCodigo(Long.parseLong(codigo1.getText().toString()));




            referencia.child("Cliente").child(p.getUid()).setValue(p);











        }
    });
    eventoDatabase1();
    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            pessoaSelecionada = (Pessoa) parent.getItemAtPosition(position);


            codigo1.setText(pessoaSelecionada.getCodigo()));// Aqui é onde dá o erro, desse jeito fica a linha em vermelho, se coloco o toString, o app para.

            cnpj1.setText(pessoaSelecionada.getCnpj());
            razao1.setText(pessoaSelecionada.getRazao());
            latitude1.setText(pessoaSelecionada.getLatitude());
            longitude1.setText(pessoaSelecionada.getLongitude());

        }
    });


}
private void eventoDatabase1(){
    referencia.child("Cliente").addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            listPessoa.clear();
            for(DataSnapshot objSnapshot:dataSnapshot.getChildren()){
                Pessoa c = objSnapshot.getValue(Pessoa.class);
                listPessoa.add(c);

            }
            arrayAdapterPessoa = new ArrayAdapter<Pessoa>(MainActivity2.this, android.R.layout.simple_list_item_1, listPessoa);
            list.setAdapter(arrayAdapterPessoa);
        }

        v.setLongitude(longitude1.getText().toString());
        v.setCodigo(Long.parseLong(codigo1.getText().toString().trim()));
        referencia.child("Cliente").child(v.getUid()).setValue(v);
        limparcampos();
    }else if( id == R.id.menu_deleta){
        Pessoa v = new Pessoa();
        v.setUid(pessoaSelecionada.getUid());
        referencia.child("Cliente").child(v.getUid()).removeValue();
        limparcampos();
    }
    return true;
}

public void limparcampos(){
    codigo1.setText("");
    cnpj1.setText("");
    razao1.setText("");

    latitude1.setText("");
    longitude1.setText("");

}

Let’s look at the method setCodigo:

public void setCodigo(Long codigo) {
    this.codigo = codigo;
}

See that he gets one Long as a parameter.

Let’s look how you’re calling the method setCodigo:

p.setCodigo(codigo1.getText().toString());

You are calling the method toString(), so you’re passing a String for a method that receives a Long, error. To correct the error, just use the method Long.parseLong:

p.setCodigo(Long.parseLong(codigo1.getText().toString()));
