Java JPanel和JLabel'；s

我试图创建两组JLabel，一组包含名称，第二组包含值。这些值从数据库中提取并显示到第二组JLabel

我似乎无法将2组JLabel对齐，以便具有名称的集合位于面板的左侧，而具有值的集合直接位于右侧。我知道我的网格布局有一个因素，我只是不知道它应该是什么

您的问题是您的

GridLayout

只有一列。您需要像这样创建

GridLayout

：

新的GridLayout（0，2）

。下面是一个小的可运行示例，它将成对的jlabel放在一起

public static void main(String[] args) {
    JFrame f = new JFrame("Good day");
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setSize(400, 250);

    JPanel panel = new JPanel(new GridLayout(0, 2));
    JLabel left = new JLabel("Foo");
    JLabel right = new JLabel(("Bar"));
    JLabel hello = new JLabel("Hello");
    JLabel world = new JLabel("World");
    panel.add(left);
    panel.add(right);
    panel.add(hello);
    panel.add(world);
    f.add(panel);

    f.setVisible(true);

首先，即使accountPanel布局是gridLayout，您也使用了BorderLayout：

JPanel accountPanel = new JPanel(new GridLayout(0, 1));
accountPanel.add(firstNameLabel, BorderLayout.WEST); // BorderLayout.WEST wrong

我的建议是，你应该使用gridbaglayout。GridbagLayout看起来很难学，但实际上它很有逻辑性

建议：研究Java Netbeans。它有一个拖放式IDE，允许您只需将元素拖放到

JFrame

上，而无需硬编码。这就是我学习如何使用

JFrame

s和

GroupLayout

s的方法。您可以创建一个名为accountPanel的JPanel，其中包含一列GridLayout。这不是Gridlayout的一个很好的用法。然后使用BorderLayout定位将组件添加到它？删除所有的

BorderLayout.WEST

s，将其切换到

GridLayout（0,2）

，并添加交替的名称和值。网格布局从左到右，然后从上到下填充。放置顺序取决于面板的ComponentOrientation属性。建议：查看Java Netbeans。它有一个拖放式IDE，允许您只需将元素拖放到
