黑莓場填補

Question

我想墊的電子郵件字段下面的代碼片段：

emailField = new BasicEditField(BasicEditField.FILTER_EMAIL|Field.FIELD_HCENTER|TextField.NO_NEWLINE|Field.HIGHLIGHT_FOCUS|Field.FOCUSABLE); 
    emailField.setLabel("Email: "); 
    emailField.setPadding(5, 5, 5, 5); 
    emailField.setBorder(BorderFactory.createRoundedBorder(new XYEdges(10, 10, 10, 10), 0x0083B0D7, Border.STYLE_SOLID)); 

是否有墊一個適當的方式，使得顯示的邊框和之間沒有保證金領域背景？

Answer 1

嘗試使用setMargin(5,5,5,5)而不是setPadding(5,5,5,5)。

Field#setMargin()
保證金是現場外的區域，邊界之後。由於這些重疊，經理正確分配利潤率。

Field#setPadding()
填充是內容和邊框之間的區域內的區域。

Field#SetBorder()
邊框是填充之外和邊距之前的區域內的區域。

UPDATE：
你是正確的，與setMargin()更換setPadding()而已，並沒有產生預期的結果。原因是您正在使用的Border，更準確地說它的厚度（）和樣式（STYLE_SOLID）。減小邊框厚度至並將其更改爲STYLE_FILLED。

上述變化

而且現在的代碼片段後：

public class PlayingWithBorders extends MainScreen { 
    public PlayingWithBorders() { 
     super(NO_VERTICAL_SCROLL | NO_HORIZONTAL_SCROLL | USE_ALL_HEIGHT | USE_ALL_WIDTH); 

     VerticalFieldManager vfm = new VerticalFieldManager(USE_ALL_HEIGHT | USE_ALL_WIDTH); 
     vfm.setBackground(BackgroundFactory.createSolidBackground(Color.CYAN)); 

     BasicEditField emailField = new BasicEditField(); 
     emailField.setLabel("Email: "); 
     emailField.setPadding(5, 5, 5, 5); 
     emailField.setMargin(5, 5, 5, 5); 
     emailField.setBorder(BorderFactory.createRoundedBorder(new XYEdges(3, 3, 3, 3), 0x0083B0D7, Border.STYLE_FILLED)); 
     emailField.setBackground(BackgroundFactory.createSolidBackground(Color.WHITE)); 

     BasicEditField passwordField = new BasicEditField(); 
     passwordField.setLabel("Password: "); 
     passwordField.setPadding(5, 5, 5, 5); 
     passwordField.setMargin(5, 5, 5, 5); 
     passwordField.setBorder(BorderFactory.createRoundedBorder(new XYEdges(3, 3, 3, 3), 0x0083B0D7, Border.STYLE_FILLED)); 
     passwordField.setBackground(BackgroundFactory.createSolidBackground(Color.WHITE)); 

     vfm.add(emailField); 
     vfm.add(passwordField); 
     add(vfm); 
    }
