Question

在另一个方法MyVimeo（）。

中调用方法GetVal（）

变量timestamp，nonce，sign是全局的并且在方法GetVal（）中打印。但是，当在MyVimeo（）方法中打印相同值时，这些值为空。

是否有任何替代方法可以将GetVal（）中的值作为String返回？

public void GetVal(final String param) {

                    NetworkEvent n = (NetworkEvent) evt;
                    n.getError().printStackTrace();
                }
            });

addToQueue是异步的，所以它已经在一个单独的线程上工作，你不需要从另一个线程调用它（你真的不应该这样做）。

您可以使用addToQueueAndWait，但最好在获取数据后调用其余的处理代码。
