Android TimePickerDialog选择的时间未传递到实际的倒计时计时器

我一直在努力获取一个时间选择器对话框来设置我的倒计时计时器。我尝试了很多方法,但都没有成功。我决定尝试一些基本的代码,我将在下面介绍。

我无法将所选时间(我在下面的代码中称之为selectedStartTime)作为startTime传递到实际的倒计时计时器中。我只能在使用预设的startTime=10000(或任何数字)时让计时器正常工作。我不希望startTime是一个固定的数字。我需要它来自时间选择器框中的OnTimeSetListener。

我将永远感谢任何能向我展示如何更改代码的人,以便在对话框中选择的时间实际用于计时器。
