java - 对齐黑莓的布局设计问题

Question

我正在开发一个应用程序，我需要在 HorizontalFieldManage 中设置两个按钮.哪里Bitmap应该留在左边和另一个 LabelField应保持水平居中。在这里我尝试了很多次但无法先设置 Bitmap在左边所以你能帮我解决这个问题吗..

这是我的代码::

VerticalFieldManager VFM = new VerticalFieldManager(USE_ALL_WIDTH){
            public void paint(Graphics g) {
                g.setBackgroundColor(Color.WHITE);
                g.clear();
                super.paint(g);
            }
        };
        HorizontalFieldManager HFM = new HorizontalFieldManager(FIELD_HCENTER){
            public void paint(Graphics g) {
                g.setBackgroundColor(Color.WHITE);
                g.clear();
                super.paint(g);
            }
        };

        Bitmap logom1;
        logom1 = Bitmap.getBitmapResource("logo48X48.png");
        BitmapField imgField = new BitmapField(logom1,Field.FIELD_LEFT);
        LabelField RegistrationLbl = new LabelField("Registration",FIELD_HCENTER | FIELD_BOTTOM);

        FontFamily fontFamily[] = FontFamily.getFontFamilies();
        Font font = fontFamily[1].getFont(FontFamily.CBTF_FONT, 20);
        font = fontFamily[1].getFont(Font.BOLD, 25);
        RegistrationLbl.setFont(font);

        HFM.add(imgField);
        HFM.add(RegistrationLbl);

        VFM.add(HFM);
        add(VFM);

试试这个(这不是正确的方法)-

        HorizontalFieldManager VFM = new HorizontalFieldManager(){
        public void paint(Graphics g) {
        g.setBackgroundColor(Color.WHITE);
        g.clear();
        super.paint(g);
        }
        };

        HorizontalFieldManager LogoHFM = new HorizontalFieldManager(FIELD_LEFT);
        Bitmap logom1;
        logom1 = Bitmap.getBitmapResource("logo48X48.png");
        BitmapField imgField = new BitmapField(logom1);
        LogoHFM.add(imgField);


        LabelField RegistrationLbl = new LabelField("Registration",FIELD_HCENTER);
        FontFamily fontFamily[] = FontFamily.getFontFamilies();
        Font font = fontFamily[1].getFont(FontFamily.CBTF_FONT, 20);
        font = fontFamily[1].getFont(Font.BOLD, 25);
        RegistrationLbl.setFont(font);
        RegistrationLbl.setMargin(0,0,0,(Display.getWidth()-logom1.getWidth())/4);


        VFM.add(LogoHFM);
        VFM.add(RegistrationLbl);
        add(VFM);
