One easy way to map that country name that you have to an int to be used in the setImageResource method is   int id   getResources   getIdentifier lowerCountryCode   drawable   getPackageName     setImageResource id     But you should really try to use different folders resources for the countries that you want to support

You can use this code     Create an array that matches any country to its id  as String   String     countriesId   new String NUMBER OF COUNTRIES SUPPORTED         Initialize the array  where the first column will be the country s name  in uppercase  and the second column will be its id  as String   countriesId 0    new String     quot US quot   String valueOf R drawable us    countriesId 1    new String     quot FR quot   String valueOf R drawable fr       and so on        And after you get the variable  quot countryCode quot   int i  for i   0  i lt countriesId length  i         if countriesId i  0  equals countryCode         break       Now  quot i quot  is the index of the country  img setImageResource Integer parseInt countriesId i  1
