You can declare an array of array into your strings.xml

First declare an array for each country

<string-array name="data01">
    <item name="code">01</item>
    <item name="country">Albania</item>
</string-array>

<string-array name="data02">
    <item name="code">02</item>
    <item name="country">Algeria</item>
</string-array>
<!--
...
-->

Then declare the array of array

<array name="countries">
    <item>@array/data01</item>
    <item>@array/data02</item>
    <!--     ...        -->
</array>

Once this done in your activity you just have to parse this array content and keep references on both countries and codes

Resources r = getResources();
TypedArray countrieCodes = r.obtainTypedArray(R.array.countries);

ArrayList<String> country = new ArrayList<String>();
ArrayList<String> code = new ArrayList<String>();

int cpt = countrieCodes.length();
for (int i = 0; i < cpt; ++i) {
    int id = countrieCodes.getResourceId(i, 0);
    code.add(r.getStringArray(id)[0]);
    country.add(r.getStringArray(id)[1]);
}

countrieCodes.recycle(); 

final ArrayList<String> fCode = code;
final ArrayList<String> fCountry = country;

final Spinner p = (Spinner)findViewById(R.id.spinner1);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, country);
p.setAdapter(dataAdapter);
p.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        String selectedCountry = (String)p.getSelectedItem();
        int selectedPosition = fCountry.indexOf(selectedCountry);
        String correspondingCode = fCode.get(selectedPosition);
        // Here is your corresponding country code
        System.out.println(correspondingCode);
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
    // TODO Auto-generated method stub
    }
});
