Android ImageView setImageResource in code

Question

I have an imageView that I want to display a little icon of the country that you are currently in  I can get the country code  but problem is I can t dynamically change the imageView resource  My image files are all lowercase  Example  country code US  image file us  My code  countryCode is the current countryCode in uppercase letters   String lowerCountryCode   countryCode toLowerCase    String resource    quot R drawable  quot    lowerCountryCode  img setImageResource resource    Now  of course this will not work because setImageResource wants an int  so how can I do this

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
