Well, I found the XML attribute android:visibility="gone" to make a hidden field so I can pass the code around... but I'm still wondering if there's a better way to do what I'm attempting.
I still have the problem of how to pre-select it the next time the spinner is visible without iterating through all the values to determine which one is at the index I want to select.
