Java – Causes the ArrayAdapterItemCategory to accept LinkedHashSet instead of ArrayList

Causes the ArrayAdapter to accept LinkedHashSet instead of ArrayList… here is a solution to the problem.

Causes the ArrayAdapter to accept LinkedHashSet instead of ArrayList

In my application, I use LinkhedHashSet instead of ArrayList to hold ItemCategory objects (POJOs with name and id attributes)
Now I want to load this LinkedHashSet in 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

 Attaching data adapter to spinner

By the way, I overridden the toString() method in the 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) { = id;

public String getName() {
        return name;

public void setName(String name) { = name;

    public String toString() {



Do not use the ArrayAdapter. Instead, start with BaseAdapter extension. You will have to replicate some of the behavior of the ArrayAdapter, but you will not be hindered by its limitations.
