Display Other Data Based On Spinner Selection

I have an xml file where I am displaying the text from the first tag, treasure name, in a spinner for the user to select. Once selected, I need to be able to access the other data

Solution 1:

I ran into same Error (java.lang.ArrayIndexOutOfBoundsException: length=12; index=-1) with spinners too. In my case, I was trying to setAdapter on spinner outside the ui thread. After wrapping the related code inside runOnUiThread, the issue is solved.
