java - 从方法中获取值

Question

我有一个被称为参数的方法，如下面的代码...我需要在我的代码中的 Oncomplete 方法之外使用参数“arry”..有没有办法可以实现这一点？

 Request request = new Request(session,
            "/fql",                         
            params,                         
            HttpMethod.GET,                 
            new Request.Callback(){         
                public void onCompleted(Response response) {
                    String arry = graphObject.getProperty("data").toString();
                }
            }

Answer 1

创建一个扩展(实现)Request.Callback 的类并将其传递给该方法。
该类可以存储String arry。

class RequestCallback extends Request.Callback {
    private String arry;

    public String getArry() {
      return arry;
    }

    public void inCompleted(Response response) {
      this.arry = graphObject.getProperty("data").toString();
    }
}

然后:

RequestCallback callback = new RequestCallback();
Request request = new Request(session, "/fql", params, HttpMethod.GET, callback);
...
// after the request is completed
callback.getArry(); // and use it.
