如何将数字与数组列表关联？

Question

I have created two spinners, a meal type spinner (eg Breakfast, lunch...) and a food spinner (eg porridge). Once the user has selected their meal type the associated foods appear in the second spinner.

Now I want to be able to create a food calculator which will multiply a set of calories for each food with a number entered by the user but I'm not sure how I associate my numbers with my array list for my spinner. Is it something like this?

private void chooseBreakfast() {
    planspinner1 = (Spinner) findViewById(R.id.planspinner);
    List<String> planlist = new ArrayList<String>();
    planlist.add("Porridge-40g/140cal");
    planlist.add("Coffee-10g/10cal");
    planlist.add("Toast-30g/87cal");
    ArrayAdapter<String> planAdapter1 = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, planlist);

    planAdapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    planspinner1.setAdapter(planAdapter1);

    ArrayList<int> food = newArrayList<int>();
    food.add(4);
    food.add(1);
    food.add(3);

}

Answer 1

do a list objects using a food class like

{
  private string name;
  private int id;
  private double calories
}

and use that in your spinner
