Fill listView

I'm trying to fill a List with values from 1 to 10 through a FOR loop and using a method.

The Commit class receives the value of "i" and the method returns the List. Look: private List compromissos() {

    String titulo = null;
    List al = Arrays.asList(new Compromisso(titulo));

    for(int i=0; i<10;i++){
        new Compromisso(String.valueOf(i));
    }

    return al;

The Commitment class looks like this: public class Compromisso { private String titulo;

public Compromisso(String titulo) {
    this.titulo = titulo;
}

public String getTitulo() {
    return titulo;
}

public void setNome(String nome) {
    this.titulo = titulo;
}

@Override
public String toString() {
    return "Título: " + titulo;
}

} Then I try to populate a listView: ... List compromissos = compromissosAgendados(); AdapterCompromissosPersonalizado adapter = new AdapterCompromissosPersonalizado(compromissos, this); ... However, when you run the program, nothing is shown in the listView. I wonder where I went wrong.

I do not know why I was very clear.
