java获取非匿名内部类信息以及给内部类变量赋值

public class CallXwalkFnData {
    public String type = "callXwalkFn";
    public String fn = "loadUrl";

    public class arg1{
        public  String url = "http://192.168.0.100:8081/";
        public String backupUrl = "file:///mnt/sdcard/res/";
        public boolean persistent = true;
    }
    arg1 arg = new arg1();
    public arg1 getArg(){
        return arg;
    }
}

上面是信息类，下面获取内部类的值和给变量赋值

CallXwalkFnData data = new CallXwalkFnData();
().url=call;

call是方法传进来的值。
