答案 0 :(得分：0)
看看这段代码......
try
{
String dateString = cursor.getString(6);
startTimer = TimeFormat.parse(dateString);
//Code for End Time
String endDateString = cursor.getString(7);
endTimer = TimeFormat.parse(endDateString);
totalBillable += endTimer.getTime() - startTimer.getTime();
}catch (ParseException e) {
Log.e("ReminderEditActivity", e.getMessage(), e);
}
很难确定，因为您的问题中发布的内容太多了，但您的意思是dateTimeFormat而不是TimeFormat吗？
答案 1 :(得分：0)
倾销“只有519行代码”，甚至没有指出哪一行代码是提出异常的代码，这无助于我们回答你的问题。
此外，Java命名约定不会使用大写字母命名数据成员和局部变量。 TimeFormat看起来像是一个类名，让像我们这样的人很难理解“只有519行代码”。
话虽如此，TimeFormat基于kk:mm，您的数据（2012-07-02 14:17:25）不是那种格式。您不应该使用TimeFormat，或者数据库中的数据是错误的。
