Java—从JSpinner返回分每秒毫秒

好的，这个问题有两个部分，第一个是如何从一个JSpinner返回分钟秒毫秒（mm:ss.SSS）。我现在设置了一个JSpinner，它在JSpinner中使用java的DateEditor格式，如下所示：

JSpinner spinner = new JSpinner();
spinner.setModel(new javax.swing.SpinnerDateModel());
spinner.setEditor(new javax.swing.JSpinner.DateEditor(spinner, "mm:ss.S"));
spinner.setBounds(420, 140, 228, 20);
contentPane.add(spinner);

但问题是，当我只想返回“分：秒.毫秒”而不想返回日期、月份或任何其他信息时，它将返回一个字符串，如“Wed Jun 06 00:26:12 MDT 2012”

问题的第二部分是如何只显示毫秒并将其更改为第十位，因此它不显示为（mm:ss.SSS），而是显示为（mm:ss.S），并且S值可以更改为介于0和9之间的值，而不是0和999之间的值。该值也需要以这种方式返回。

而不是使用DateEditor，您应该使用自定义的JSpinner.Editor

这里有一个例子，非常类似于您想要的，这样做：

您可以使用日历提取分钟、秒和毫秒。以下是一个例子：

SpinnerDateModel model = (SpinnerDateModel) spinner.getModel();
Calendar time = Calendar.getInstance();
time.setTime(model.getDate());
// Access minute, second, millisecond
time.get(Calendar.MINUTE);
time.get(Calendar.SECOND);
time.get(Calendar.MILLISECOND);

设置默认值应按如下方式工作：

Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);

SpinnerDateModel model = new SpinnerDateModel(cal.getTime(), null,
            null, Calendar.SECOND);

JSpinner spinner = new JSpinner();
spinner.setModel(model);

关于问题的第一部分。。。不久前我遇到了一个类似的问题，我需要一个能够管理小时/分钟/秒的微调器

我编写了JSpinner类的一个新实现，您可以使用它作为基础，并对其进行更新以获得分/秒/毫秒微调器。我与您分享“原样”，它符合我的个人需求，但我肯定可以提高：

/**
 * TimeSpinner
 * A implementation of JSpinner that manages
 * only the hour/minute part of a date.
 * Careful, in consequence the getValue()
 * gives you a date based on the 01/01/1970
 * ('issue' known about JSpinner).
 * => This spinner implements its own model. It allows to fix
 * a pb about the tick (the regular model SpinnerDateModel
 * increases/decreases hours instead of minutes.
 * => It overrides setBackground and make it works (the regular
 * JSpinner.setBackground does not).

那么，我如何将默认时间设置为00:00.000呢？@clangfan1我添加了一个默认时间的示例。
