所以我有一个倒计时器，用户可以选择他们想要的轮数，每个轮的时间和休息时间。这一切都有效，而且很棒。
我创建了第二个文本视图，用户可以看到它的总长度。
我的问题是：每次我的textview（带有回合的那个）改变它都会产生一定的延迟，这使得我的其他textview（总时间）每轮留下几秒钟（虽然它工作正常但是它只是延迟）。
我知道这是一个问题，textview有轮次而不是总时间，但我无法弄清楚原因。
有人可以看看吗？
这是一张图片，你可以看到我的总计时器还剩3个。 Problem here
谢谢

答案 0 :(得分：0)
用于设置回合的结束时间：
Calendar c = Calendar.getInstance();
c.add(Calendar.MINUTE, 10);//Replace with round time
long time = c.getTimeInMillis();
现在就抽出时间：
long currentTime = Calendar.getInstance().getTimeInMillis();
设置Culculate分钟和秒数：
long deltaT = time-currentTime;//This is in milliseconds
int minutes = deltaT/60000;
int seconds = deltaT%60000
