I have a string variable which is the same as the identifier for a view.
I would like to use the R.id.xxx, but obviously I can't just replace the xxx with my string as the xxx is actually an int. What can I do to get around this?
Thanks!

Nonsense. The framework obviously discourages that approach but it is possible: just use Java reflection, e.g.,
java.lang.reflect.Field f = R.id.class.getField(name);
int id = f == null ? -1 : (Integer)f.get(null);
// now just use findViewById(id);

String s=getString(R.string.xxx);

Sorry this isn't quite what I meant. I am trying to retrieve a handle to a LinearLayout. Usually I would use findViewById(R.id.idname). I have idname as a string - how can I use the findViewById method as this takes an int?

Sounds like you want to replace a variable name.This is not possible

findViewById() takes integer as parameter and the integer parameter is determined by android system.How you can refer with other variable
