JLayeredPane无法正确显示

我正在为国际象棋编程gui,我正在使用JLayeredpane,以便在JFrame上显示黑白图块,然后在JLayeredpane的下一层上,我将显示棋子,我是新手。 Jlayeredpane,我不太了解如何使用它,我无法将碎片图层叠加在tile图层上,我尝试将不透明度设置为false,并尝试将背景色设置为0,0,0, 0个想法?

我创建了一个jpanel,该jpanel包含一个具有黑白背景的jpanel数组,然后创建了另一个jpanel,它包含一个jlabels数组,这些jlabel的文本显示了棋子。

总代码:

class frame extends JFrame implements MouseListener, MouseMotionListener{

private JLabel[][]label;

private int xIndex;

private int yIndex;

private JPanel[][]panels;

private JPanel mainPanel;

private JPanel labelPanel;

    public frame() {    
        super("Chessboard");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        label = new JLabel[8][8];
        mainPanel = new JPanel();
        panels = new JPanel[8][8];
        labelPanel = new JPanel();
        mainPanel.setLayout(new GridLayout(8,8));
        addTiles();
        labelPanel.setLayout(new GridLayout(8,8));
        addButtons();
        JLayeredPane mainPane = new JLayeredPane();
        add(mainPane);
        mainPane.add(mainPanel,1);
        mainPane.add(labelPanel, 2);
        setBoard();
        setSize(new Dimension(500,500));
        setVisible(true);
    }

    public void setBoard(){

         label[0][0].setText("\u2656");
         label[0][7].setText("\u2656");
         label[0][1].setText("\u2658");
         label[0][2].setText("\u2657");
         label[0][3].setText("\u2655");
         label[0][4].setText("\u2654");
         label[0][5].setText("\u2657");
         label[0][6].setText("\u2658");
         label[7][0].setText("\u265C");
         label[7][1].setText("\u265E");
         label[7][2].setText("\u265D");
         label[7][3].setText("\u265B");
         label[7][4].setText("\u265A");
         label[7][5].setText("\u265D");
         label[7][6].setText("\u265E");
         label[7][7].setText("\u265C");

         for(int i =0; i <8 ;i++){
             label[1][i].setText("\u2659");

         }

         for(int i =0; i <8 ;i++){
             label[6][i].setText("\u265F");

         }

    }

    public void addTiles(){

            for(int i =0; i<8;i++){


            for(int k =0; k<8;k++){

            panels[i][k] = new JPanel();

                if(i%2 == 1){

                    if(k%2 == 0){

        panels[i][k].setBackground(Color.gray);

        }else{

        panels[i][k].setBackground(Color.WHITE);

        }

        }else{

                    if(k%2 == 1){

                    panels[i][k].setBackground(Color.gray);

                    }else{

                    panels[i][k].setBackground(Color.WHITE);

                    }

                }

                mainPanel.add(panels[i][k]);

            }

            }

    }

    public void addButtons(){

        for(int i =0; i<8;i++){
            for(int k =0; k<8;k++){

                label[i][k] = new JLabel();

                label[i][k].setLayout(null);

    label[i][k].setFont(label[i][k].getFont().deriveFont(29f));

                label[i][k].addMouseListener(this);

                label[i][k].addMouseMotionListener(this);

                labelPanel.add(label[i][k]);

            }


        }
    }

    public void findIndex(MouseEvent arg0){

        for(int x =0; x<8;x++){

            for(int y =0; y <8; y++){

                if(arg0.getSource().equals(label[x][y])){

                    xIndex = x;

                    yIndex = y;


                }   
            }   
        }   
    }

    public void mouseDragged(MouseEvent arg0) {

        findIndex(arg0);

        int mouseX = arg0.getX();

        int mouseY = arg0.getY();

        label[xIndex][yIndex].setLocation(mouseX, mouseY);
    }

我想要这样,使碎片层显示在黑白jpanels的图块层的顶部,并且颜色可见。
