I have a ListView showing names of countries. I have stored the names in strings.xml as a string-array called country_names.

1. As one of the possibilities, you may store 2 different arrays in XML: string array and integer array, and then programmatically put them in the HashMap.

   Definition of arrays:

   <?xml version="1.0" encoding="utf-8"?>
   <resources>
       <string-array name="countries_names">
           <item>USA</item>
           <item>Russia</item>
       </string-array>
   
       <integer-array name="countries_codes">
           <item>1</item>
           <item>7</item>
       </integer-array>
   </resources>
   

   And code:

   String[] countriesNames = getResources().getStringArray(R.array.countries_names);
   int[] countriesCodes = getResources().getIntArray(R.array.countries_codes);
   
   HashMap<String, Integer> myMap = new HashMap<String, Integer>();
   for (int i = 0; i < countriesNames.length; i++) {
       myMap.put(countriesNames[i], countriesCodes[i]);
   }
   

2. It may be a file with any name. See this
