對于我個人項目的一部分，我想在我的程序中添加一個音樂播放器。但是，當我嘗試使用 GridBagConstraintsLayout 在標簽正下方制作 3 個按鈕（播放、暫停和停止）時，布局看起來就像我附加的圖片一樣奇怪。我不想讓播放按鈕很長。我希望所有 3 個按鈕的長度相等并直接位于標簽下方。有人可以幫我解決這個問題，也許可以發布代碼來幫助我嗎？附上我現在擁有的圖片，我還包含了一些代碼。panel = new JPanel(new GridBagLayout()); add(panel); GridBagConstraints c = new GridBagConstraints(); label1 = new JLabel("This is the MaryLand State Song. After exiting, press enter"); c.gridx = 0; c.gridy = 0; panel.add(label1,c); play = new JButton("Play"); c.gridx = 0; c.gridy = 2; c.fill = GridBagConstraints.HORIZONTAL; panel.add(play,c); pause = new JButton("Pause"); c.gridx = 1; c.gridy = 2; c.fill = GridBagConstraints.HORIZONTAL; panel.add(pause,c); stop = new JButton("Stop"); c.gridx = 2; c.gridy = 2; c.fill = GridBagConstraints.HORIZONTAL; panel.add(stop,c);

希望這可以幫助
GridBagLayout lay = new GridBagLayout();
// three columns with same weights
lay.columnWeights = new double[] {1,1,1};
panel = new JPanel(lay);
add(panel);
GridBagConstraints c = new GridBagConstraints();
label1 = new JLabel("This is the MaryLand State Song. After exiting, press enter");
c.gridx = 0; c.gridy = 0;
// make label span all next to last columns (cells)
c.gridwidth = GridBagConstraints.REMAINDER;
panel.add(label1,c);
c.gridwidth = GridBagConstraints.BOTH;
c.fill = GridBagConstraints.HORIZONTAL;
play = new JButton("Play");
c.gridx = 0; c.gridy = 1;
panel.add(play,c);
pause = new JButton("Pause");
c.gridx = 1; c.gridy = 1;
panel.add(pause,c);
stop = new JButton("Stop");
c.gridx = 2; c.gridy = 1;
panel.add(stop,c);
