Making an ArrayAdapter<ItemCategory> accept LinkedHashSet instead of ArrayList

Question

In my app Im using a LinkhedHashSet instead of an ArrayList to hold ItemCategory objects (POJOs with name and id properties) Now I want to load this LinkedHashSet in a Spinned without having to convert the LinkedHashsSet to an ArrayList beforehand. Is it possible? Here is my code

public static void loadSpinnerData(Context context, ArrayList<ItemCategory> array, Spinner spinner) {

    // Creating adapter for spinner
    ArrayAdapter<ItemCategory> dataAdapter = new ArrayAdapter<ItemCategory>(context,
            R.drawable.simple_spinner_item, array);

    // Drop down layout style - list view with radio button
    dataAdapter
            .setDropDownViewResource(R.drawable.simple_spinner_dropdown_item);

    // Attaching data adapter to spinner
    spinner.setAdapter(dataAdapter);
}

}

btw I've overriden the toString() method in ItemCategory object to return the category name:

public class ItemCategory {

    private int id;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

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

}

Don't use an ArrayAdapter. Instead, extend from BaseAdapter. You'll have to duplicate some of the behavior of ArrayAdapter, but you won't be hampered by its restrictions.
