Question: I'm trying to populate a ListView with an ArrayList.
The ArrayList contains Usuarios Objects. Usuario has two fields (String nombre, String edad).
This is my code:

```
ListView listview = (ListView) findViewById(R.id.ListView1);
ArrayList<Usuario> listaUsuarios = (ArrayList<Usuario>) dao.showAll();

ArrayAdapter<Usuario> adapter = new ArrayAdapter<Usuario>(this, android.R.layout.simple_list_item_1, listaUsuarios);
listview.setAdapter(adapter);

```

When I test my Android App, it looks like this:

The ListView doesn't show the Usuario fields (nombre, edad) it shows es.dga.sqlitetest.Usuario@43e4...

Can anyone help me? Thanks

Answer: 
You should provide a `toString()` method for `Usuario`. Something like:

```
@Override
public String toString() {
 return this.label;
}

```
hope this helps

Also look up ArrayAdapter interface: 

```
  ArrayAdapter(Context context, int textViewResourceId, List<T> objects)

```
