如何在黑莓中的水平字段管理器中创建三个编辑字段

Question

如何创建三个编辑字段，例如

 HorizontalFieldManager hfm_city=new HorizontalFieldManager();
 VerticalFieldManager vfm_city = new VerticalFieldManager();
 vfm_city.setBorder(
                  BorderFactory.createBitmapBorder(

                  ); 
            vfm_city.setMargin(0, 200, 0, 0);
            final EditField city = new EditField("", "", 30, BasicEditField.FILTER_DEFAULT){
                                            String emptyString = "City";

Answer 1

你正在以正确的方式前进。但你必须给出具体的宽度和宽度。高度为VerticalFieldManager，否则默认为全宽。

VerticalFieldManager vfm_city = new VerticalFieldManager() {
    protected void sublayout(int maxWidth, int maxHeight) {
        super.sublayout(Display.getwidth()/3,30);
        setExtent(Display.getwidth()/3,30);
    }
};

在你所在的国家和地区做这件事。城市vfm并添加hfm并尝试。
