问题描述

我有这显示某些对话框和进度条一项活动。结果
这项活动并没有调用的setContentView通过这次活动没有屏幕布局。它已被刚刚用于显示对话框和进度条的对话框。

I have one Activity which displayed some Dialog boxes and Progress bars.
This activity does not have call to setContentView as this Activity does not have Screen Layout. It has been just used for displaying Dialogs and progress bar dialogs.
