Pass Database values to Spinner

Question

I am searching client values in the database through PHP/MYSQL and I am returning via JSON, and I would like to pass to SPINNER more than 1 argument (idclient + client name)... In this case, I managed to run the SPINNER by passing the "client name" that appears to be selected... How do I pass the "client" also... In this case, I would like to replace the SPINNER ID with the "idclient"... Below is the code that I return the JSON, including in the Adapter...

Below is the code edited with the modifications, full code.

Client class

public class Cliente {

private int mId;
private String mNome;

public Cliente(int id, String nome) {
    mId = id;
    mNome = nome;
}

public int getId() {
    return mId;
}

public String getNome() {
    return mNome;
}

}

Registration Class

public class RegistrarActivity extends AppCompatActivity {

private ImageView botaoVoltar;
private Button botaoRegistrar;
private EditText textoCPF, textoEmail;
private Spinner spinnerCliente;
private Cliente cliente;
private String idcliente;
private ArrayList<Cliente> clientes = new ArrayList<>();

private StringRequest request, request2;

@Override

    botaoVoltar = (ImageView) findViewById(R.id.botaoVoltarId);

Answer 1

Create a class Cliente, with the variables id and nome and go storing the json data in a ArrayList<Cliente>

Ex:

public class Cliente {

    private int mId;
    private String mName;

    public Cliente(int id, String name) {
        mId = id;
        mName = name;
    }

    public int getId() {
        return mId;
    }

    public String getName() {
        return mName;
    }

    public String toString() {
        return mName;
    }   
}

ArrayList<Cliente> clientes = new ArrayList<>();
clientes.add(new Cliente(1, "Fulano 1"));
clientes.add(new Cliente(2, "Fulano 2"));

When creating Spinner Adapter, associate with Arraylist above. Ex:

ArrayAdapter spinnerAdapter = new ArrayAdapter(this,
            android.R.layout.simple_spinner_item, clientes);

To access a Spinner client:

Cliente cliente;
Spinner spinner; // Inicialize com o findViewById, setAdapter, etc


spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        cliente = (Cliente) parent.getItemAtPosition(position);
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
        cliente = null;
    }
});
