It is not possible to do what you suggested.

Instead, a possible workaround might be to use the following function:

public int getDrawableId(String name){
        try {
            Field fld = R.drawable.class.getField(name);
            return fld.getInt(null);
        } catch (Exception e) {
        return -1;

and use like:

 String imagename="blablaimage";
