无法显示我的Textview1和Textview2之间的计算时间差？

问题描述 投票：0回答：2

enter image description here

这是我的应用程序的屏幕截图，其中的时间为00:57:18，超时时间14:14:21应该自动计算为时差，结果将以总旅行时间显示（带红色圆圈）

您认为我需要更改我的代码以使输出正确显示在总时差中，谢谢您。

这是我的代码。

我认为您需要在下面的文本视图中显示时差。希望以下代码有助于清除您的疑问。 

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:mm:ss");

date1 = simpleDateFormat.parse("00:57:18");
date2 = simpleDateFormat.parse("14:14:21");

long difference = date2.getTime() - date1.getTime();
hours = (int) ((difference - (1000*60*60)); 
min = (int) (difference - (1000*60*60*hours)) / (1000*60);
sec = (int) (difference - (1000*60*60*hours)) - (1000*60*min)) / (1000);
hours = (hours < 0 ? -hours : hours);
Log.i("======= Hours"," :: "+hours);
Log.i("======= Minutes"," :: "+min);
Log.i("======= Seconds"," :: "+sec);

为了计算时间，我使用了这个：

long difference = date2.getTime() - date1.getTime(); 
days = (int) (difference / (1000*60*60*24));  
hours = (int) ((difference - (1000*60*60*24*days)) / (1000*60*60)); 
min = (int) (difference - (1000*60*60*24*days) - (1000*60*60*hours)) / (1000*60);

您可以使用以下代码将文本转换为Date对象

  DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); 
 Date dateObject;

try{
String dob=(tx.getText().toString());
dateObject = formatter.parse(dob);
date = new SimpleDateFormat("dd/MM/yyyy").format(dateObject);

}
