倒数计时器问题

Question

我正在使用倒数计时器，并将其设置为可以由用户设置。当计时器到达00:00时它应该说“完成！”。出于某种原因，我得到了“完成！”在我启动计时器之后。点击暂停并恢复后，显示我的柜台倒计时，但我不确定客户会因此而变得很酷。任何人都可以告诉我为什么会遇到这个问题？谢谢。

斩去初始化代码混淆我在那里，因为它太一会儿注意到你的括号不均衡......

它看起来像你创建计数器和初始化它既的外onclick功能。在这个阶段长度为零。

当您单击开始按钮时，长度被设置为有效时间，但计时器不会重新初始化，因此它以先前设置的零值开始并立即启动。

当您按暂停时，计算正确的剩余时间，然后将其传递到您在恢复时创建的新计数器，然后继续正常倒计时。

将counter = new MyCount(length, 100);直接移动到dialog.show();}之后应该确保在单击设置的定时器按钮时计数器被初始化并解决问题。
