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:

   
   
       
           USA
           Russia
       
   
       
           1
           7
       
   
   

   And code:

   String[] countriesNames = getResources().getStringArray(R.array.countries_names);
   int[] countriesCodes = getResources().getIntArray(R.array.countries_codes);
   
   HashMap myMap = new HashMap();
   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
