JFormattedTextField :输入持续时间值

本文介绍了JFormattedTextField :输入持续时间值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想使用 JFormattedTextField 来允许用户将时间 duration 值输入到表单中.示例有效值为:

I want to use a JFormattedTextField to allow the user to input time duration values into a form. Sample valid values are:

2h 30m72h 15m6h0h

但是我在这方面取得的成功有限.有人可以建议如何做到这一点吗?如果使用 JTextField 也可以实现此结果，我就可以了.

However I am having limited success with this. Can some one please suggest how this can be accomplished? I am OK if this result can be achieved using a JTextField as well.

谢谢！

如果值得的话，这是我目前的尝试:

If it is worth anything, here's my current attempt:

mFormattedText.setFormatterFactory( new DefaultFormatterFactory( new DateFormatter( new SimpleDateFormat("H mm"))));

这有点像:

• 我无法让 h 和 m 显示为纯文本(我尝试转义) *
• 小时数有最大值

• I cannot get h and m to appear as plain text (I tried escaping) *
• The number of hours has a max
