Populate ListView using List

I am trying to display data from my sqlite database. In my DatabaseHandler.java I have this method:

public List<Item> getAllItemsinList() {
    List<Item> itemList = new ArrayList<Item>();
    // Select All Query
    String selectQuery = "SELECT  * FROM " + TABLE_ITEMS;

    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(selectQuery, null);

    // looping through all rows and adding to list
    if (cursor.moveToFirst()) {
        do {
            Item item = new Item();
            item.set_id(Integer.parseInt(cursor.getString(0)));
            item.set_name(cursor.getString(1));
            item.set_description(cursor.getString(2));
            // Adding contact to list
            itemList.add(item);
        } while (cursor.moveToNext());
    }

    // return item list
    return itemList;
}

It returns a List with the type Item.

In my MainActivity.java I have this method:

private void populateListViewUsingList(){
    List<Item> items;
    items = db.getAllItemsinList();
    listView = (ListView) findViewById(R.id.listItems);
    ArrayAdapter<Item> itemArrayAdapter = new ArrayAdapter<Item>(this,android.R.layout.simple_list_item_1, items);
    listView.setAdapter(itemArrayAdapter);
}

The listview is populated, however, objects are being displayed instead of the data the database contains. Example of text being displayed is migueld.rivera.catalogapp.Item@42a97320. What is the correct way of parsing data? Thanks.
