    我的问题是,在“输入时间”的标签下面,我放了一个空白标签。当我把 JTextField 在那里,我不能像上面的图片一样对齐它,因为它的单元格与 JLabel 上面。我试过 gridwidth , gridheight (-用于上下按钮), weightx , insets ,并添加空白 标签类 (-占用行末尾的空间)。所有这些都失败了。我不知道我做错了什么。我也知道我不必打电话 setPreferredSize 但我必须这样做,因为我希望时间场的宽度与上面的图片一样。我认为上下按钮的对齐方式不会像图中那样,因为在 GridBagLayout 两者之间没有任何区别。我已经试着设置 垂直高度 将时间字段的值设置为2,结果仍然是这样的。有没有像图片中那样对齐这些字段的方法?

    我想您没有意识到GridBagLayout与GridNxM一起工作,这意味着同一列中的所有组件都具有相同宽度的单元格,而同一行中的所有元素都位于相同高度的单元格中。这只是一个网格。

    问题很简单,您在列0中有一些组件:“输入日期:”标签、输入日期文本字段。。。因此,最宽的组件决定了该列的大小。现在,您需要放置一组文本字段、标签和按钮来表示[14:00向上/向下]。你现在做的方法是首先放置一个空标签,它实际上不做任何事情(除了使用它的单元格),然后将所述组件放在第2、3、4列。。。

    然而,正如我所说的,列0非常宽,因此列1+从已经放置的所有内容的右侧开始,这就是为什么所有这些组件都显示在“右侧”,因为列0非常窄。

    现在,要让他们处于正确的位置,有两种选择。要么使上面的所有组件都跨越多个列,这样您就可以使用这些列将您所需的所有内容放在这些组件下面,要么使用这些组件创建一个面板,然后将该面板放在“输入时间:”下的列0中

    在我看来,第二种方法要好得多,所以我去定义了一个 timeInputPanel 用我们需要的组件填充它,然后将其放入 panel_4 。现在因为 时间输入面板 只有一个组件,即使它包含几个其他组件,它也可以在列0内无任何问题地驻留。

    相关代码如下:

    JPanel timeInputPanel = new JPanel(new FlowLayout(FlowLayout.LEADING));
    timeInputPanel.add(text_33);
    timeInputPanel.add(label_4);
    timeInputPanel.add(text_4);
    timeInputPanel.add(upDownPanel);
    
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 1.0;
    c.weighty = 1.0;
    c.gridx = 0;
    c.gridy = 15;
    c.insets = new Insets(0, 10, 0, 0);
    panel_4.add(timeInputPanel, c);
    

    当然,您可能希望根据自己的喜好更改GridBagConstraints,唯一重要的是 c.gridx = 0; 和一个合适的 gridy .

    它看起来像这样:
