连接...或无效的mmi代码android studio

Question

我的应用程序包含一个列表视图，其中包含从数据库中检索的数据。该数据库包含以下列：cognome，nome，ruolo，telefono。 当我点击某个项目时，会打开一个包含2个按钮的对话框：call和sms。

我希望当我点击按钮call时，我将呼叫转移到与该行对应的号码。 问题是，当我单击按钮时，出现错误消息：＆gt;连接问题或无效的mmi代码。

我的主要内容如下。

public class ListaContatti extends ListActivity {

    PersonaManager manager;
    List<Persona> lista = new ArrayList<>();
    TextView visualizza;
    private PersonaHelper mPersonaHelper;

        mPersonaHelper = new PersonaHelper(this);
        manager = new PersonaManager(this);
        manager.open();
        visualizzaLista();
        //stampaCose();
        manager.close();

        setListAdapter(adapter);

    }
