Question

我有一个倒数计时器工作正常，除了我在100秒内输入的数字超过2位数。我正在创建2个日历对象，在毫秒时间内输入，然后减去它。代码

    long milsecs1= calendar1.getTimeInMillis();
    long milsecs2 = calendar2.getTimeInMillis();

    long diff = milsecs2 - milsecs1;
    long dsecs = diff / 1000;

    long ddays = diff / (24 * 60 * 60 * 1000);  
    diff=diff-ddays *(24 * 60 * 60 * 1000); 
    textDays.setText(   Integer.toString( (int)ddays)+":" );

    long dhours = diff / (60 * 60 * 1000);
    diff=diff-dhours* (60 * 60 * 1000);
    textHours.setText(   Integer.toString( (int)dhours)+":" );

    long dminutes = diff / (60 * 1000);
    diff=diff-dminutes* (60 * 1000);
    textMinuts.setText(   Integer.toString( (int)dminutes)+":" );

/////////////////////////////////////////////////
// THIS IS THE PART THAT IS NOT WORKING, I WANT NUMBERS 0-99, BUT GETTING NUMBERS LIKE 230
    long dseconds = diff / (100);
    textSeconds.setText(   Integer.toString( (int)dseconds)+":" );
    diff=diff-dseconds;

Joda time在其Period class中提供了一个更简单（并且经过彻底验证）的解决方案。这样的事情应该可以做到（未经测试）：

Period period = new Period(calendar1.getTimeInMillis(), calendar2.getTimeInMillis());
int days = period.getDays();
int hours = period.getHours();
... etc.

无法使倒计时器具有100秒的秒数
