我去年做了类似的事情，这里是我的代码的简化版本，可能会对您有所帮助:

public class MapPanel {

    int r = 30; // radius of hexagone
    int h = (int) Math.sqrt(r*r*3/4);
    int[] xPoints = {r/2,3*r/2,2*r,3*r/2,r/2,0};
    int[] yPoints = {0,0,h,2*h,2*h,h};
    int[] xp = new int[6];
    int[] yp = new int[6];

    public void paint(Graphics g){

        int xoffset = 0;
        int yoffset = 0;

        // display map
        for (int j = 0; j < /* put width here */; j++) {
            for (int i = 0; i < /* put height here */; i++) {
                for (int k = 0; k < 6; k++) {
                    xp[k] = xPoints[k]+xoffset;
                    yp[k] = yPoints[k]+yoffset;
                }
                g.setColor(Color.black);
                g.drawPolygon(xp, yp, 6);
                yoffset += 2*h;
            }
            yoffset = h-yoffset % (2*h);
            xoffset += 3*r/2;
        }   
    }
}

如果您想要公式的解释，只需谷歌“六边形”...
