很抱歉没有提供太多信息；我是 Java 新手。请问你能帮我这个代码吗？我想将标签和文本字段彼此对齐，并将所有按钮对齐在一行中。我怎样才能做到这一点？

以下是我创建 GroupLayout 的方式：

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);

这是我创建水平组的方式：

layout.setHorizontalGroup(

  layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)

  .addComponent(jPanel1, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)

  .addGroup(layout.createParallelGroup()

  .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.TRAILING)

  .addGroup(layout.createSequentialGroup()

  .addComponent(jScrollPane1, javax.swing.GroupLayout.PREFERRED_SIZE, 400, javax.swing.GroupLayout.PREFERRED_SIZE))

  .addGroup(layout.createParallelGroup()
    .addGap(40, 40, 40)
    .addComponent(jLabel2)
    .addComponent(txtitem, javax.swing.GroupLayout.PREFERRED_SIZE, 100, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel3)
    .addComponent(txtprice, javax.swing.GroupLayout.DEFAULT_SIZE, 100,javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel4) 
    .addComponent(txtquantity, javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel5)
    .addComponent(txtreorder, javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btnupdate)//,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)//,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(btndelete,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(btnload,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(btnadd)//,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(txtreorder)
    .addComponent(jLabel5))
    )
  )
);

这是我创建 VerticalGroup 的方式：

layout.setVerticalGroup(
  layout.createParallelGroup()
    .addGroup(layout.createSequentialGroup()
    .addComponent(jPanel1, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addGap(40, 40, 40)
    .addGroup(layout.createSequentialGroup()
    .addComponent(jLabel2)
    .addComponent(txtitem, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel3)
    .addComponent(txtprice, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel4)
    .addComponent(txtquantity, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel5)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    // .addComponent(btnadd))
    .addGap(40, 40, 40)
    .addComponent(btnadd,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btnupdate,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btndelete,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btnload,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
    .addComponent(jScrollPane1, javax.swing.GroupLayout.DEFAULT_SIZE, 200, Short.MAX_VALUE)
    .addContainerGap()

您永远不会被迫为所有组件使用单个面板。

我想将标签和文本字段彼此对齐

也许使用带有八个 SpringLayout 或 GridBagLayout 的面板。阅读 Swing 教程中有关如何使用布局管理器的部分以获取更多信息和示例。

以及单行中的所有按钮。

也许使用带有FlowLayout.

然后将第一个面板添加到对话框的 CENTER，将按钮面板添加到 SOUTH。

像这样的东西：

label1.setBounds(2,2,50,25); 
textField1.setBounds(10,2,50,25);

ETC ...对于您要以编程方式放置的每个项目。

您需要使用 (x,y,w,h) 坐标来满足您的需求。
