java获取非匿名内部类信息以及给内部类变量赋值

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

public class arg1{
public  String url = "http://192.168.0.100:8081/test002.html";
public String backupUrl = "file:///mnt/sdcard/res/backup.html";
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

[code]CallXwalkFnData data = new CallXwalkFnData();
data.getArg().url=call;

call是方法传进来的值。
