问题描述
我有一个非常简单的问题，我不知道如何解决。我想在它的运行并显示更改进度对话框的消息文本。这方面的一个例子是像一个剩余时间计数器，而进度动画旋转，将倒计时。我不知道我会如何处理这因为这样做progressDialog.setMessage（字符串），即使正在运行的线程内，不会改变在对话框本身什么。谢谢！
I've got a fairly simple issue I'm not sure how to resolve. I want to change the message text of a Progress Dialog while it's running and showing. An example of this would be something like a "time remaining" counter that would count down while the progress animation is spinning. I'm not sure how I would approach this because doing progressDialog.setMessage(String), even within a running thread, will not change anything in the Dialog itself. Thank you!
