黑莓场填补

Question

我想垫的电子邮件字段下面的代码片段：

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)); 

是否有垫一个适当的方式，使得显示的边框和之间没有保证金领域背景？

Answer 1

尝试使用setMargin(5,5,5,5)而不是setPadding(5,5,5,5)。

Field#setMargin()
保证金是现场外的区域，边界之后。由于这些重叠，经理正确分配利润率。

Field#setPadding()
填充是内容和边框之间的区域内的区域。

Field#SetBorder()
边框是填充之外和边距之前的区域内的区域。

UPDATE：
你是正确的，与setMargin()更换setPadding()而已，并没有产生预期的结果。原因是您正在使用的Border，更准确地说它的厚度（）和样式（STYLE_SOLID）。减小边框厚度至并将其更改为STYLE_FILLED。

上述变化

而且现在的代码片段后：

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); 
    }
