这是我的第一个 GUI 应用程序，我无法使它看起来整洁。我尝试了几种布局并对其进行了修改，例如流、网格、边框。当我运行程序时，一切都混杂在一起。

我希望它看起来像：

Unloaded Measurement      |textfield| |textfield|
Loaded Rider Measurement  |textField| |textfield|
Loaded Bike Measurement   |textField| |Textfield|

                   |Button|
_______________________________________________________________________________________

Race Sag: |TextField|
Free Sag: |TextField|
Race Sag Notes: |       TextField         |
Free Sag Notes: |       TextField         |

使用此处的其他一些建议（包括 GridBagLayout）可以实现您想要的布局，但迄今为止最简单的解决方案是使用JGoodies FormLayout，因为它明确设计用于创建需要排列字段和标签的布局.

Try calling pack() on your JFrame, the layout doesn't get applied immediately when you set it. Alternatively, you can use validate(), which should lay out the component as well. Btw. in your sample code you don't set a layout manager.

GroupLayout，请参见此处，在带标签的表单上做得很好，并且可以作为子面板进行管理。
