我有一个水平管理器，显示3个标签字段，屏幕上显示“1:00 Event1”，我想设置hfm的背景颜色仅覆盖1点，我该怎么做？

HorizontalFieldManager horizontalFieldManager_left15 = new HorizontalFieldManager(
                Manager.HORIZONTAL_SCROLL);

        horizontalFieldManager_left15.add(time15Label);
        horizontalFieldManager_left15.add(min15Label);

         horizontalFieldManager_left15.add(evetnLabel);

参考这个 -

HorizontalFieldManager horizontalFieldManager_left15 = new HorizontalFieldManager(
            Manager.HORIZONTAL_SCROLL);

LabelField lb = new LabelField(time15Label)  {

//设置背景颜色

protected void paint(Graphics graphics) {
         graphics.setColor(Color.LAVENDAR);
            super.paint(graphics);
        }
    };

//设置TextArea的背景颜色

 protected void paintBackground(Graphics graphics) {
         graphics.setBackgroundColor(Color.GOLDENROD);
         graphics.clear();
        }
    };



   horizontalFieldManager_left15.add(time15Label);
