Java 子对象在管理器中的自定义位置（按坐标）

如何在不使用HorizontalFieldManager或VerticalFieldManager以及不使用setMargin（）的情况下，通过自定义位置的坐标将字段放置在管理器中：

非常感谢

试试这样的方法：

public Manager getCustomManager() {
        Manager myCustomManager = new Manager(Manager.NO_HORIZONTAL_SCROLL|Manager.NO_HORIZONTAL_SCROLLBAR|Manager.NO_VERTICAL_SCROLL|Manager.NO_VERTICAL_SCROLLBAR ) {
            protected void sublayout(int width, int height) {
                //Suppose we have to place two fields in our Manager
                if (getFieldCount() == 2) {
                    int
                    /** width and height values for the two fields */
                    w1, h1 , w2, h2 ,
                    /** position values for the two fields */
                    x1=5, y1=5, x2=10, y2=20;

                    // Get the first field added to the manager
                    Field f1 = getField(0);
                    h1 = f1.getHeight();
                    w1 = f1.getWidth();
                    // set the available width and height for the first field
                    layoutChild(f1, w1, h1);
                    // Set the position of the first field in the manager
                    setPositionChild(f1, x1, y1);

                    // Get the second field added to the manager
                    Field f2 = getField(1);
                    h2 = f2.getHeight();
                    w2 = f2.getWidth();
                    // set the available width and height for the second field
                    layoutChild(f2, w2, h2);
                    // Set the position of the second field in the manager
                    setPositionChild(f2, x2, y2);

                    setExtent(width, height);
                } else {
                    setExtent(0, 0);
                    // or  you can do something else in this case...
                }
            };
        };
        return myCustomManager;
    }

是的，使用BlackBerry，您可以通过循环管理器的子字段列表来实现这一点。使用setPositionChild（child，x，y）定位子字段。请在HeartBeat检查此问题

 public static class MyCustomManager extends Manager {
       public MyCustomManager () {
           super();
        }
       public void paint(Graphics g) {/**my painting*/super.paint(g);}
       protected void sublayout(int width, int height) {
        super.sublayout(PLOT, AUKST);

        setPositionChild(??,??)     //Something like this?
        setPosition(??, ??);        // or this? how?
        setExtent(??, ??);
        }

       }

public Manager getCustomManager() {
        Manager myCustomManager = new Manager(Manager.NO_HORIZONTAL_SCROLL|Manager.NO_HORIZONTAL_SCROLLBAR|Manager.NO_VERTICAL_SCROLL|Manager.NO_VERTICAL_SCROLLBAR ) {
            protected void sublayout(int width, int height) {
                //Suppose we have to place two fields in our Manager
                if (getFieldCount() == 2) {
                    int
                    /** width and height values for the two fields */
                    w1, h1 , w2, h2 ,
                    /** position values for the two fields */
                    x1=5, y1=5, x2=10, y2=20;

                    // Get the first field added to the manager
                    Field f1 = getField(0);
                    h1 = f1.getHeight();
                    w1 = f1.getWidth();
                    // set the available width and height for the first field
                    layoutChild(f1, w1, h1);
                    // Set the position of the first field in the manager
                    setPositionChild(f1, x1, y1);

                    // Get the second field added to the manager
                    Field f2 = getField(1);
                    h2 = f2.getHeight();
                    w2 = f2.getWidth();
                    // set the available width and height for the second field
                    layoutChild(f2, w2, h2);
                    // Set the position of the second field in the manager
                    setPositionChild(f2, x2, y2);

                    setExtent(width, height);
                } else {
                    setExtent(0, 0);
                    // or  you can do something else in this case...
                }
            };
        };
        return myCustomManager;
    }
