Question

I want to do

String childImg = "childIcon";
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.????, 0, 0, 0);

I use this to get drawable id

getResources().getIdentifier(childImg, "drawable", getPackageName())

use getIdentifier()

int id = getResources().getIdentifier("name_of_resource", "id", getPackageName());

Do it like this:

String childImg = "childIcon";
int id = getResources().getIdentifier(childImg, "drawable", getPackageName())
textView.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0);

yes, a little since it has to loop through all your resource elements to find the correct one. – waqaslam May 31 '12 at 20:50
So it's probably better to have an integer array in a singleton class if you're making many calls...right? – Tushar May 31 '12 at 20:51
yes, indeed. But if you dont have huge list of resource elements then perhaps you may ignore the performance issue – waqaslam May 31 '12 at 20:54
