推荐答案

一种方法是使用 OverlayLayout.对于要在两个轴上位于图像中心的文本，0.5 的对齐值应该用于 X 和Y 对于两个 JLabel 组件如下所示.

One way is to use OverlayLayout. For the text to be at the center of the image in both axes an alignment value of 0.5 should be used for both X & Y for both JLabel components shown below.

public class OverlayLabelApp {
    public static void main(String args[]) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                JFrame frame = new JFrame("Overlay App");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

                JPanel panel = new JPanel();

                LayoutManager overlay = new OverlayLayout(panel);
                panel.setLayout(overlay);

                JLabel label1 = new JLabel("Centered Text");
                label1.setForeground(Color.GREEN);
                label1.setFont(new Font("SansSerif", Font.BOLD, 16));
                label1.setAlignmentX(0.5f);
                label1.setAlignmentY(0.5f);
                panel.add(label1);

                JLabel label2 = 
                  new JLabel(new ImageIcon(OverlayLabelApp.class.getResource("/images/sunset.png")));                   label2.setAlignmentX(0.5f);
                label2.setAlignmentY(0.5f);
                panel.add(label2);

                frame.add(panel);
                frame.pack();
                frame.setVisible(true);
            }
        });
    }
}
