Pass context when you create your adapter, Use that context to get the inflated view.

Adapter adapter = new Adapter(this);

Then in Adpater Class constructor :

public Adapter(Context context){
context.findViewById(R.id.textview);//consider this as numero textview
}

Then access it as per your requirement. Hope it helps!

You can set OnClickListener interface provided by View class. Something like this.

Implement listener on your activity class 

public class SpinnerActivity extends AppCompatActivity implements
    View.OnClickListener

Declare class level variables for your views

private TextView tvNumero;
private ImageView ivRemove, ivEdit, ivContactCall;

Find initialise value in onCreate() method

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_gildi_spinner);

    tvNumero = (TextView) findViewById(R.id.numero)
    ivRemove = (ImageView) findViewById(R.id.remove);
    ivEdit = (ImageView) findViewById(R.id.edit);
    ivContactCall = (ImageView) findViewById(R.id.contactCall);

    ivRemove.setOnClickListener(this);
    ivEdit.setOnClickListener(this);
    ivContactCall.setOnClickListener(this);
}

Implemented class from Onclickistener, where you get on click event for your registered views

@Override
public void onClick(View v) {

    switch (v.getId()) {
        case R.id.remove:
        case R.id.edit:
        case R.id.contactCall:
            Toast.makeText(this, tvNumero.getText().toString(), Toast.LENGTH_SHORT).show();
            break;
    }
}

NOTE : tvNumero.getText().toString() gives you the value of your desired TextView.

UPDATE :

  • Firstly replace your ListView with RecyclerView

Refer RecyclerView Example tutorial.

  • Secondly to achieve onClick for your listed items

Refer recyclerview-onclick tutorial.
