How to convert from drawable to int-array

I have an int-array like this:

private int icons[] = new int[] {R.drawable.itr300, R.drawable.itr3500};

But I want to place it in the array.xml.

If I do it like this:

<resources>
<array name="icons">
    <item>@drawable/itr300</item>
    <item>@drawable/itr3500</item>
</array>
</resources>

private TypedArray images = getResources().obtainTypedArray(R.array.icons);
private int icons[] = images...

Now I want to convert Drawable into the int-array. But I don't know how to do it. Can anybody help?

Comment:

I think your answer were useful. But I have not found the answer yet. Can you help me again, to find the syntax errors? I seems good, but I will not work.

   private TypedArray images = getResources().obtainTypedArray(R.array.icons);
   private int[] icons = new int[images.length()];  
    for (int i = 0; i < icons.length(); i++) {
        icons[i] = images.getResourceId(i, 0);
    }

do it like this

        public override View GetView(int position, View convertView, ViewGroup parent)
    {
        View row = null;

        if(convertView == null)
        {
            LayoutInflater i = (LayoutInflater)context.GetSystemService(Context.LayoutInflaterService);
            row = i.Inflate(Resource.Layout.custom_menu, parent, false);
        }
        else
        {
            row = convertView;
        }

        TextView title = row.FindViewById<TextView>(Resource.Id.menu_title);
        ImageView icon = row.FindViewById<ImageView>(Resource.Id.menu_icon);


        title.Text = menuTitle[position];
        //icon.SetImageResource(menuIcon[position]);
        icon.SetImageResource(Icon.GetResourceId(position,-1));

        return row; 
    }
