Java Swing有没有可用的免费日期和时间选择器？

Java Swing有没有可用的免费日期和时间选择器？

有很多日期选择器可用,但没有日期和时间选择器.这是我到目前为止最接近的:寻找日期和时间选择器

任何人？

对于时间选择器,您可以使用JSpinner并设置仅显示时间值的JSpinner.DateEditor.

JSpinner timeSpinner = new JSpinner( new SpinnerDateModel() );
JSpinner.DateEditor timeEditor = new JSpinner.DateEditor(timeSpinner, "HH:mm:ss");
timeSpinner.setEditor(timeEditor);
timeSpinner.setValue(new Date()); // will only show the current time

[LGoodDatePicker](https://github.com/LGoodDatePicker/LGoodDatePicker)库包含一个好的**DateTimePicker组件**.(以及各个DatePicker和TimePicker类).这三个组件简单易用.以下是组件和演示应用程序的一些屏幕截图.[截图1](http://i.stack.imgur.com/ghDdI.png),[截图2](http://i.stack.imgur.com/QXgWE.png).项目主页位于https://github.com/LGoodDatePicker/LGoodDatePicker.

您可以扩展swingx JXDatePicker组件:

"JXDatePicker只处理没有时间的日期.通常我们需要让用户选择一个日期和时间.这是一个如何使用JXDatePicker一起处理日期和时间的例子."

编辑:这篇文章从网络上消失了,但正如SingleShot发现的那样,它仍然可以在互联网档案中找到.只是为了确定,这是完整的工作示例:

import org.jdesktop.swingx.calendar.SingleDaySelectionModel;
import org.jdesktop.swingx.JXDatePicker;

import javax.swing.*;
import javax.swing.text.DefaultFormatterFactory;
import javax.swing.text.DateFormatter;
import java.text.DateFormat;
import java.text.ParseException;
import java.util.*;
import java.awt.*;

使用两者结合..这就是我做的:

public static JPanel buildDatePanel(String label, Date value) {
JPanel datePanel = new JPanel();

JDateChooser dateChooser = new JDateChooser();
if (value != null) {
    dateChooser.setDate(value);
}
for (Component comp : dateChooser.getComponents()) {
    if (comp instanceof JTextField) {
    ((JTextField) comp).setColumns(50);
    ((JTextField) comp).setEditable(false);
    }
}

datePanel.add(dateChooser);

SpinnerModel model = new SpinnerDateModel();
JSpinner timeSpinner = new JSpinner(model);
JComponent editor = new JSpinner.DateEditor(timeSpinner, "HH:mm:ss");
timeSpinner.setEditor(editor);
if(value != null) {
    timeSpinner.setValue(value);
}

datePanel.add(timeSpinner);

return datePanel;
}
