Java JPanel und JLabels

Question

Ich versuche, 2 Sätze von JLabels zu erstellen, ein Satz würde einen Namen enthalten und der zweite Satz würde Werte enthalten. Die Werte werden aus einer Datenbank abgerufen und für den zweiten Satz von JLabels angezeigt.

Ich kann nicht scheinen, wie die 2 Sätze von JLabels ausgerichtet werden, so dass der Satz mit den Namen auf der linken Seite des Panels wäre und der Satz mit den Werten wäre direkt auf der rechten Seite. Ich weiß, dass mein Gitternetz einen Faktor hat. Ich weiß einfach nicht, was es sein soll.

Answer 1

Ihr Problem ist, dass Ihre GridLayout nur 1 Spalte hat. Sie müssen Ihre GridLayout wie folgt erstellen: new GridLayout(0, 2). Im Folgenden finden Sie ein kleines ausführbares Beispiel, das JLabels direkt nebeneinander aufteilt.

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); 
} 

Answer 2

Zunächst einmal, auch wenn Ihr accountPanel Layout ist gridlayout, Sie ist es Border verwendet haben:

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

Mein Vorschlag, sollten Sie dafür verwenden GridBagLayout. GridbagLayout scheint schwierig zu lernen, aber es ist eigentlich ziemlich logisch.

Ich habe Ihren Code ein wenig geändert.
