Question

How do I get all items in a Spinner?

I was having trouble trying to search a way to get all items from a Spinnerbut I was not able to find an elegant solution. The only solution seems to be storing the items list before to add it to the Spinner

Is there another better way to do this?

Write custom adapter. In adapter add method that returns item list... — dieter_h, Aug 20 '15 at 20:11
I have no control over the adapter. I am just receiving the Spinner in my method and I just know the kind of Class of the items — Antonio, Aug 20 '15 at 20:14
`List items = ((CastMyAdapterType)mySpinner.getAdapter()).getList();` — dieter_h, Aug 20 '15 at 20:17
I cannot find this method in `android.widget.Adapter` neither in `android.widget.SpinnerAdapter` — Antonio, Aug 20 '15 at 20:20

A simple and elegant way to do this is, if you know the objects type that the spinner is storing:

public class User {

    private Integer id;

    private String name;

    /** Getters and Setters **/

    @Override
    public String toString() {
        return name;
    }
}

Given the previous class and a Spinner that contains a list of User you can do the following:

public List<User> retrieveAllItems(Spinner theSpinner) {
    Adapter adapter = theSpinner.getAdapter();
    int n = adapter.getCount();
    List<User> users = new ArrayList<User>(n);
    for (int i = 0; i < n; i++) {
        User user = (User) adapter.getItem(i);
        users.add(user);
    }
    return users;
}

This helped me! I hope it would do it for you!
