Image View set Image Resource in code

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 

    String lowerCountryCode = countryCode.toLowerCase();
    String resource = "R.drawable." + lowerCountryCode;
    img.setImageResource(resource);
int id = getResources().getIdentifier(lowerCountryCode, "drawable", getPackageName());
setImageResource(id);

abve is my code.

Now, of course this will not work because set Image Resource wants an int, so how can i do this? Thanks in advance

I mean you know the name of files(Drawable) which you wanna use for one and other country. 

ImageView imgView=(ImageView)findViewById(R.id.imageView1);
int id = getResources().getIdentifier(lowerCountryCode.toLowerCase(), "drawable", getPackageName());
imgView.setImageDrawable(res.getDrawable(id));

The following code should work well (assuming that you really have a file with name lowerCountryCode in your res/drawable/ folder)

String lowerCountryCode = countryCode.toLowerCase();
int id = getResources().getIdentifier(lowerCountryCode, "drawable", getPackageName());
ivCard[0].setImageResource(id);
