Blackberry用户界面设计-可自定义的UI？

Question

我正在尝试设计Blackberry应用程序，我想知道是否有关于如何创建自定义用户界面元素，现有皮肤外观的资源以及还有哪些其他可能性？

我已经开发了一些带有自定义UI和内容的iPhone应用程序，因此不确定BB world在UI开发方面提供了什么。

任何提示，建议或想法都很好。

Bold 9000上标准媒体应用程序外观的示例删除了无效的ImageShack链接-切片的媒体应用程序删除了死的ImageShack链接-切片图像使用ButtonField的扩展来映射带有按钮的图像：class BitmapButtonField extends ButtonField {    Bitmap mNormal;    Bitmap mFocused;    Bitmap mActive;    int mWidth;    int mHeight;    public BitmapButtonField(Bitmap normal, Bitmap focused,         Bitmap active) {        super(CONSUME_CLICK);        mNormal = normal;        mFocused = focused;        mActive = active;        mWidth = mNormal.getWidth();        mHeight = mNormal.getHeight();        setMargin(0, 0, 0, 0);        setPadding(0, 0, 0, 0);        setBorder(BorderFactory                    .createSimpleBorder(new XYEdges(0, 0, 0, 0)));        setBorder(VISUAL_STATE_ACTIVE, BorderFactory                .createSimpleBorder(new XYEdges(0, 0, 0, 0)));    }    protected void paint(Graphics graphics) {        Bitmap bitmap = null;        switch (getVisualState()) {        case VISUAL_STATE_NORMAL:            bitmap = mNormal;            break;        case VISUAL_STATE_FOCUS:            bitmap = mFocused;            break;        case VISUAL_STATE_ACTIVE:            bitmap = mActive;            break;        default:            bitmap = mNormal;        }        graphics.drawBitmap(0, 0, bitmap.getWidth(), bitmap.getHeight(),                bitmap, 0, 0);    }    public int getPreferredWidth() {        return mWidth;    }    public int getPreferredHeight() {        return mHeight;    }    protected void layout(int width, int height) {        setExtent(mWidth, mHeight);    }}将HorizontalFieldManagers放入VerticalFieldManagers中，反之亦然对正常，聚焦和活动状态使用不同的图像如果需要自定义形状的按钮，则可以在super.paint（）之后的管理器paint（）方法重写中绘制它们其余部分代码：class Scr extends MainScreen implements FieldChangeListener {
