如何在黑莓的第三垂直領域經理添加2個垂直領域經理？

Question

嗨，請告訴我如何使這個屏幕在黑莓。 我的數據沒有添加在它上面。我使用垂直字段管理器來添加所有組件。

Answer 1

它的工作。我創造了它。使用此代碼

public class home extends UiApplication { 

public static void main(String[] args) 
{ 
    home app = new home(); 
    app.enterEventDispatcher(); 
} 

MainScreen screen = new MainScreen(); 
private int deviceWidth = Display.getWidth(); 
private int deviceHeight = Display.getHeight(); 
LabelField lbl1 = new LabelField("label"); 
final Bitmap backgroundBitmap = Bitmap.getBitmapResource("bg1.jpg"); 
final Bitmap backgroundBitmap1 = Bitmap.getBitmapResource("bg2.jpg"); 
final BitmapField mybitmapField = new BitmapField(Bitmap.getBitmapResource("facebook-logo.jpg"),DrawStyle.HCENTER); 

public home() 
{ 
    super(); 
    pushScreen(screen); 

    VerticalFieldManager mainManager = new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR) 
     {   
      public void paint(Graphics graphics) 
      { 
       graphics.clear(); 
       graphics.drawBitmap(0, 0, deviceWidth, deviceHeight, backgroundBitmap, 0, 0);      
       super.paint(graphics); 
      }    
     }; 
     //this manger is used for adding the componentes 
    VerticalFieldManager subManager = new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR) 
     { 
      public void paint(Graphics graphics) 
      { 
       graphics.clear(); 
       graphics.drawBitmap(0, 0, deviceWidth, deviceHeight, backgroundBitmap1, 0, 0);      
       super.paint(graphics); 
      } 
     }; 

     screen.add(mainManager); 
     mainManager.add(lbl1); 
     mainManager.add(subManager); 

     subManager.add(mybitmapField); 
     subManager.add(new LabelField("Data 1")); 
     subManager.add(new LabelField("Data 1")); 
     subManager.add(new LabelField("Data 1")); 
} 
} 

輸出將是這樣的。

找到如何確保以下畫面的例子：

VerticalFieldManager manager = new VerticalFieldManager(); 
    VerticalFieldManager first = new VerticalFieldManager(); 
    VerticalFieldManager second = new VerticalFieldManager(); 

    first.add(label); 
    second.add(image); 
    second.add(data); 
    second.add(data); 
    second.add(data); 

    manager.add(first); 
    manager.add(second); 
    add(manager);
