Question

我需要将我的应用程序从iPhone移植到黑莓手机，但我是新手。

在我的应用程序中，我有一些标签下的按钮。看来我不能通过坐标设置任何视图。我应该使用现场经理（FM）保证。所以，在这种情况下，我需要有按钮垂直FM和它的标签，用于按钮一些水平FM，以及按钮的forizo​​ntal外长 垂直FM（PictureBackgroundButtonField - 从customButtonsDemo类）

VerticalFieldManager vfm = new VerticalFieldManager(); 
     HorizontalFieldManager hfm1 = new HorizontalFieldManager(); 
     HorizontalFieldManager hfm2 = new HorizontalFieldManager(); 
     HorizontalFieldManager hfm3 = new HorizontalFieldManager(); 

     VerticalFieldManager sho = new VerticalFieldManager(); 
     shopping = new PictureBackgroundButtonField("HomePage/Home Shoping.png", Field.FOCUSABLE); 
     shopping.setChangeListener(this); 
     sho.add(shopping); 
     sho.add(new RichTextField("Shopping",Field.NON_FOCUSABLE)); 
     hfm1.add(sho); 

     VerticalFieldManager din = new VerticalFieldManager(); 
     dining = new PictureBackgroundButtonField("HomePage/Home Dinning.png", Field.FOCUSABLE); 
     dining.setChangeListener(this); 
     din.add(dining); 
     din.add(new RichTextField("Dining",Field.NON_FOCUSABLE)); 
     hfm1.add(din); 

     VerticalFieldManager ent = new VerticalFieldManager(); 
     entertainment = new PictureBackgroundButtonField("HomePage/Home Entertainment.png", Field.FOCUSABLE); 
     entertainment.setChangeListener(this); 
     ent.add(entertainment); 
     ent.add(new RichTextField("Entertainment",Field.NON_FOCUSABLE)); 
     hfm1.add(ent); 

     VerticalFieldManager map = new VerticalFieldManager(); 
     maps = new PictureBackgroundButtonField("HomePage/Home Maps.png", Field.FOCUSABLE); 
     maps.setChangeListener(this); 
     map.add(maps); 
     map.add(new RichTextField("Maps",Field.NON_FOCUSABLE)); 
     hfm2.add(map); 

     VerticalFieldManager pro = new VerticalFieldManager(); 
     promotions = new PictureBackgroundButtonField("HomePage/Home Promotions.png", Field.FOCUSABLE); 
     promotions.setChangeListener(this); 
     pro.add(promotions); 
     pro.add(new RichTextField("Promotions",Field.NON_FOCUSABLE)); 
     hfm2.add(pro); 

     VerticalFieldManager par = new VerticalFieldManager(); 
     parking = new PictureBackgroundButtonField("HomePage/Home Parking.png", Field.FOCUSABLE); 
     parking.setChangeListener(this); 
     par.add(parking); 
     par.add(new RichTextField("Parking",Field.NON_FOCUSABLE)); 
     hfm2.add(par); 

     VerticalFieldManager wha = new VerticalFieldManager(); 
     whatson = new PictureBackgroundButtonField("HomePage/Home WhatsOn.png", Field.FOCUSABLE); 
     whatson.setChangeListener(this); 
     wha.add(whatson); 
     wha.add(new RichTextField("What's On",Field.NON_FOCUSABLE)); 
     hfm3.add(wha); 

     VerticalFieldManager moe = new VerticalFieldManager(); 
     moeinfo = new PictureBackgroundButtonField("HomePage/Home MOEinfo.png", Field.FOCUSABLE); 
     moeinfo.setChangeListener(this); 
     moe.add(moeinfo); 
     moe.add(new RichTextField("MOE Info",Field.NON_FOCUSABLE)); 
     hfm3.add(moe); 

     VerticalFieldManager fac = new VerticalFieldManager(); 
     facebook = new PictureBackgroundButtonField("HomePage/Home Facebook.png", Field.FOCUSABLE); 
     facebook.setChangeListener(this); 
     fac.add(facebook); 
     fac.add(new RichTextField("Facebook",Field.NON_FOCUSABLE)); 
     hfm3.add(fac); 

     vfm.add(hfm1); 
     vfm.add(hfm2); 
     vfm.add(hfm3); 
     add(vfm); 

但只有我在每个hfm *中显示的第一个按钮。 athers在哪里？

文本字段使用全部水平空间，因此水平字段管理器中的第二个按钮位于屏幕之外。在这种情况下，您需要将文本字段变为子类，以使其具有自定义大小或使用其他内容。
