Here is some code that may fix your problem.

Explanation:

Assuming you have two spinners R.id.spinnerCountry and R.id.spinnerCountryCode.

As you can see i created two arrays which contains countryName and countryCode respectively.

Work Flow:-

When i select one item in a Spinner then the other spinner loads with another item corresponding to the position.

The code is Self-Explanatory!
