我有我的AsyncTask运行活动时首次启动，那么，如果网络连接不可用，那么我有一个刷新按钮，尝试运行的AsyncTask再试一次。但我得到一个调试错误说这个..

I have my asyncTask run when the activity first starts, then if network connectivity is not available then i have a refresh button that tries to run the asyncTask to try again. But i get a debug error saying this..

反正有两次运行此？

Is there anyway to run this twice?

推荐答案

刚刚创建另一个实例并执行它。

Just create another instance and execute it.
