How to assign Image Resource to ImageView with String in Android

Question

I am trying to create a routine that will assign a card image to an ImageView without using something like this: R.drawable.card_10clover. I would prefer to use a string, but the way I'm doing it doesn't work.

String imgRes = "R.drawable.card_";
int num = 10;
imgRes += "10";
String suit = "clover";
imgRes += "suit;
ImageView card = (ImageView) findViewById(R.id.imgcard);
card.setImageResource(imgRes);

Unfortunately setImageResource only takes an int. Please help.

Thank you, Jack Blue

Answer 1

Use getIdentifier (String name, String defType, String defPackage); Your imgRes does not need the prefix R.drawable

String imgRes = "card_";
int num = 10;
imgRes += "10";
String suit = "clover";
imgRes += "suit;
ImageView card = (ImageView) findViewById(R.id.imgcard);
int resourceId = getResource().getIdentifier (imgRes, "drawable", "com....");
card.setImageResource(resourceId);
