Utiliser l'extension de ButtonField à l'image d'une carte avec des boutons:

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);
    }
}

• mettre HorizontalFieldManagers à l'intérieur de VerticalFieldManagers et vice versa
• utiliser des images différentes de la normale, concentrée et active les états
• si vous avez besoin d'un personnalisé en forme de boutons, vous pouvez attirer plus dans le gestionnaire de peinture() la méthode de remplacement, une fois super.paint()

Reste de la partie de code:
