Dynamically build a resource Identifier

I am tring to get a开发者_高级运维 resource dynamically using

 String[] stringarray = res.getStringArray(R.array.XXXX);

Where XXXX is a variable. Any Suggestions? Thanks

int resID = getResources().getIdentifier("the_variable",
    "id", "your.package.name");
String[] stringarray = res.getStringArray(resID);
