在机器人在做doinbackground UI任务（） [英] Doing UI task in doinbackground() in Android

问题描述

有没有办法做UI任务中的AsyncTask的doinbackground（）。我深知这是更好地做到这一点在onPostExecute方法。但是，在我的情况，因为我需要使用可重复使用的警报，能够访问用户界面在我doinbackground可以节省我很多时间。也就是说，我需要调整code。在46的地方，但能够做到这一点，在doinbackground将需要在一个地方的变化。

Is there a way to do UI task in the doinbackground() of the AsyncTask. I am well aware it is better to do it in onPostExecute method. But in my case since I am need to use a reusable alert, being able to access the UI in my doinbackground would save me a lot of time. That is, I need to tweak the code in 46 places but being able to do this in the doinbackground will need the change in just one place.

在此先感谢

                        // some code #3 (Write your code here to run in UI thread)
