如何应对方向变化与ProgressDialog的表现？ [英] How to deal with orientation change with a ProgressDialog showing?

问题描述

我显示一个 ProgressDialog 中的AsyncTask对象的在preExecute 方法和取消ProgressDialog在 onPostExecute 方法。在 doInBackground 方法，我做了用户注册的HTTP请求。我希望允许屏幕方向的变化。当我改变方向，而 doInBackground 的方法仍然在运行，我得到各种有趣的错误像抛出：IllegalArgumentException：查看未连接到窗口管理器和RegisterScreen渗漏窗口......

I am showing a ProgressDialog in the onPreExecute method of an AsyncTask object and canceling the ProgressDialog in the onPostExecute method. In the doInBackground method I am making an HTTP request for user registration. I wish to allow screen orientation changes. When I change the orientation while the doInBackground method is still running, i get all sorts of fun errors like 'IllegalArgumentException: View not attached to window manager' and 'RegisterScreen has leaked window...'

我怎样才能正确地继续的方向改变后，显示 ProgressDialog ？或者，也许，我怎么能禁用用户的请求后，方向更改提交他们的注册？

How can I properly continue to show the ProgressDialog after an orientation change? Or maybe, how can I disable orientation change after the user requests to submit their registration?
