如何复选框，labelField属性添加到Horizo​​ntalFieldManager

Question

我写了一个简单的程序，增加了两个编辑字段的字段经理：

HorizontalFieldManager hrfm = new HorizontalFieldManager(Manager.HORIZONTAL_SCROLL);   

    EditField editField1 = new EditField();   
    editField1.setText("User Name:"); 
    EditField editField2 = new EditField(); 
    editField2.setText("Hello"); 

    hrfm.add(editField1); 
    hrfm.add(editField2); 
    add(hrfm); 

但是当我运行模拟器它仅仅只显示用户名字段。我无法找到其他编辑字段。为什么会出现这个问题。在添加复选框labelField时，我也面临类似的问题。请帮助我使用这个FieldManager。谢谢

Hope this will helps you. 

EditField editField1 = new EditField();   
editField1.setText("User Name:"); 
EditField editField2 = new EditField(); 
editField2.setText("Hello"); 
int Width = editField1.getPrefferedWidth()+editField2.getPrefferedWidth(); 
int Height = editField1.getPrefferedHeight()+editField2.getPrefferedHeight(); 
HorizontalFieldManager hrfm = new HorizontalFieldManager(Manager.HORIZONTAL_SCROLL) 
{ 
    protected void sublayout(int maxWidth, int maxHeight) { 
       super.sublayout(Width, Height); 
       super.setExtent(Width, Height) 
      } 
}   
hrfm.add(editField1); 
hrfm.add(editField2); 
add(hrfm);
