如何更新每一秒时间用Java模拟器？ [英] How to update time every second in Java emulator?

问题描述

我一直在code为一个应用程序，但是当我运行code我不能在模拟器中更新的时间。在code工作在编译器而不是模拟器。
任何有帮助的建议将是极大的AP preciated。定时器是倒数圣诞节。
这里是我的code：

 今天日历= Calendar.getInstance（）;
日历thatDay = Calendar.getInstance（）;
thatDay.set（Calendar.DAY_OF_MONTH，25）;
thatDay.set（的Calendar.MONTH，11）; // 0-11所以少1
thatDay.set（Calendar.YEAR，2014年）;
thatDay.set（Calendar.HOUR，0）;
thatDay.set（Calendar.MINUTE，0）;
thatDay.set（Calendar.SECOND，0）;
thatDay.set（Calendar.AM_PM，0）;的System.out.println（thatDay.getTime（））;ScheduledExecutorService的ScheduledExecutorService的=Executors.newScheduledThreadPool（1）;
scheduledExecutorService.scheduleAtFixedRate（新ReadThisPeriod（thatDay），0，1，
TimeUnit.SECONDS）;长差异=（thatDay.getTimeInMillis（） -  today.getTimeInMillis（））/ 1000;
长天=差异/（60 * 60 * 24）;
时间长=差异/（60 * 60）％24;
长期分钟=差异/ 60％60;
长秒=差异％60;TextView的daysBox =（的TextView）findViewById（R.id.s1Days）;daysBox.setText（++日++时间++分++秒+）;
 

解决方案

也有一些小的添加到 rupps 答案。您可以使用

DateUtils.getRelativeTimeSpanString（长时间，现在，长minResolution）;

要简化数学和给予更多的用户可读的字符串用户。

I have been working on a code for an app but I cannot get the time to update in the emulator when I run the code. The code works in the compiler but not the emulator. Any helpful suggestions would be greatly appreciated. The timer is a countdown to Christmas day. Here is my code:

Calendar today = Calendar.getInstance();
Calendar thatDay = Calendar.getInstance();
thatDay.set(Calendar.DAY_OF_MONTH, 25);
thatDay.set(Calendar.MONTH, 11); // 0-11 so 1 less
thatDay.set(Calendar.YEAR, 2014);
thatDay.set(Calendar.HOUR, 0);
thatDay.set(Calendar.MINUTE, 0);
thatDay.set(Calendar.SECOND, 0);
thatDay.set(Calendar.AM_PM, 0);

System.out.println(thatDay.getTime());

ScheduledExecutorService scheduledExecutorService= 

Executors.newScheduledThreadPool(1);
scheduledExecutorService.scheduleAtFixedRate(new ReadThisPeriod(thatDay), 0, 1,  
TimeUnit.SECONDS);

long diff = (thatDay.getTimeInMillis() - today.getTimeInMillis()) / 1000;
long days = diff / (60 * 60 * 24);
long hours = diff / (60 * 60) % 24;
long minutes = diff / 60 % 60;
long seconds = diff % 60;

TextView daysBox = (TextView) findViewById(R.id.s1Days);

daysBox.setText(" + "" + days + "" + hours + "" + minutes + " " + seconds + " ");

解决方案

Also some little add to rupps answer. You can use

DateUtils.getRelativeTimeSpanString(long time, long now, long minResolution);

to simplify math and give more user readable string for user.
