如何在單屏上顯示黑莓手機中的數據

Question

嗨，朋友們如何在單個屏幕上顯示黑莓手機中的數據。 例如：

---

current Date------------value. 
Name------------------- value. 
roll--------------------value. 
email-id----------------value. 
phone-no----------------value. 
pass--------------------value. 
class-------------------value. 
sex---------------------value. 
college-----------------value. 
city--------------------value. 
state-------------------value. 
pin code----------------value. 
country-----------------value. 

public LabelField lbSr, lbDate, lbAllo, lbMob, lbDetail, lbRemark, lbSlaDate, lbEmail, lbStatus, lbspace; 
public LabelField lb1Sr, lb1Date, lb1Allo, lb1Mob, lb1Detail, lb1Remark, lb1SlaDate, lb1Email, lb1Status; 
public JustifiedHorizontalFieldManager jhfm1,jhfm2,jhfm3,jhfm4,jhfm5,jhfm6,jhfm7,jhfm8,jhfm9; 
VerticalFieldManager vfm=new VerticalFieldManager(VerticalFieldManager.VERTICAL_SCROLL); 

lb1Sr = new LabelField("SRNo   :"); 
lb1Sr.setColor(Color.BLACK); 

lbSr = new LabelField(strSerno); 
lbSr.setColor(Color.BLACK); 

lb1Date = new LabelField("SRDate  :"); 
lb1Date.setColor(Color.BLACK); 

lbDate = new LabelField(strDate); 
lbDate.setColor(Color.BLACK); 

lb1Allo = new LabelField("AllocDate :"); 
lb1Allo.setColor(Color.BLACK); 

lbAllo = new LabelField(strAllo); 
lbAllo.setColor(Color.BLACK); 

lb1Mob = new LabelField("MobNo  :"); 
lb1Mob.setColor(Color.BLACK); 

lbMob = new LabelField(strMob); 
lbMob.setColor(Color.BLACK); 

lb1Detail = new LabelField("SRDetails :"); 
lb1Detail.setColor(Color.BLACK); 

lbDetail = new LabelField(strDetail); 
lbDetail.setColor(Color.BLACK); 

lb1Remark = new LabelField("Remarks :"); 
lb1Remark.setColor(Color.BLACK); 

lbRemark = new LabelField(strRemark); 
lbRemark.setColor(Color.BLACK); 

lb1SlaDate = new LabelField("SLADate :"); 
lb1SlaDate.setColor(Color.BLACK); 

lbSlaDate = new LabelField(strSldate); 
lbSlaDate.setColor(Color.BLACK); 

lb1Email = new LabelField("Email :"); 
lb1Email.setColor(Color.BLACK); 

lbEmail = new LabelField(strEmail); 
lbEmail.setColor(Color.BLACK); 

lb1Status = new LabelField("Status :"); 
lb1Status.setColor(Color.BLACK); 

lbStatus = new LabelField(strStatus); 
lbStatus.setColor(Color.BLACK); 

jhfm1=new JustifiedHorizontalFieldManager(lb1Sr, lbSr, true); 
vfm.add(jhfm1); 

jhfm2=new JustifiedHorizontalFieldManager(lb1Date, lbDate, true); 
vfm.add(jhfm2); 

jhfm3=new JustifiedHorizontalFieldManager(lb1Allo, lbAllo, true); 
vfm.add(jhfm3); 

jhfm4=new JustifiedHorizontalFieldManager(lb1Mob, lbMob, true); 
vfm.add(jhfm4); 

hfm5=new JustifiedHorizontalFieldManager(lb1Detail, lbDetail, true); 
vfm.add(jhfm5); 

jhfm6=new JustifiedHorizontalFieldManager(lb1Remark, lbRemark, true); 
vfm.add(jhfm6); 

jhfm7=new JustifiedHorizontalFieldManager(lb1SlaDate, lbSlaDate, true); 
vfm.add(jhfm7); 

jhfm8=new JustifiedHorizontalFieldManager(lb1Email, lbEmail, true); 
vfm.add(jhfm8); 

jhfm9=new JustifiedHorizontalFieldManager(lb1Status, lbStatus, true); 
vfm.add(jhfm9); 

add(vfm); 

我想表明與兩側滾動選項的所有數據。

試試這個代碼 -

VerticalFieldManager vfm=new VerticalFieldManager(VerticalFieldManager.VERTICAL_SCROLL); 
LabelField date=new LabelField("Date :"); 
LabelField date_value=new LabelField(value); 
JustifiedHorizontalFieldManager jfm_date=new JustifiedHorizontalFieldManager(date,date_value, true); 
vfm.add(jfm_date); 
LabelField name=new LabelField("Name:"); 
LabelField name_value=new LabelField(value); 
JustifiedHorizontalFieldManager jfm_name=new JustifiedHorizontalFieldManager(name,name_value, true); 
vfm.add(jfm_name); 
add(vfm); 

等等....添加所有這樣的領域。

JustifiedHorizo​​ntalFieldManager類如下─

public class JustifiedHorizontalFieldManager extends Manager 
{ 
    private static final int SYSTEM_STYLE_SHIFT = 32; 

public Field _leftField; 
public Field _rightField; 

private boolean _giveLeftFieldPriority; 

public JustifiedHorizontalFieldManager(Field leftField, Field rightField, boolean giveLeftFieldPriority) 
{ 
    this(leftField, rightField, giveLeftFieldPriority, Field.USE_ALL_WIDTH); 
}

{ 
    super(style); 

    _leftField = leftField; 
    _rightField = rightField; 

    add(_leftField); 
    add(_rightField); 

    _giveLeftFieldPriority = giveLeftFieldPriority; 
} 

public JustifiedHorizontalFieldManager(boolean giveLeftFieldPriority, long style) 
{ 
    super(style); 
    _giveLeftFieldPriority = giveLeftFieldPriority; 
} 

public void addLeftField(Field field) 
{ 
    if(_leftField != null) { 
     throw new IllegalStateException(); 
    } 
    _leftField = field; 
    add(_leftField); 
} 

public void addRightField(Field field) 
{ 
    if(_rightField != null) { 
     throw new IllegalStateException(); 
    } 
    _rightField = field; 
    add(_rightField); 
} 

public int getPreferredWidth() 
{ 
    return _leftField.getPreferredWidth() + _rightField.getPreferredWidth(); 
}

    if(_giveLeftFieldPriority) { 
     firstField = _leftField; 
     secondField = _rightField; 
    } else { 
     firstField = _rightField; 
     secondField = _leftField; 
    } 

    int maxHeight = 0; 

    int availableWidth = width; 
    availableWidth -= _leftField.getMarginLeft(); 
    availableWidth -= Math.max(_leftField.getMarginRight(), _rightField.getMarginLeft()); 
    availableWidth -= _rightField.getMarginRight(); 

    layoutChild(firstField, availableWidth, height - firstField.getMarginTop() - firstField.getMarginBottom()); 
    maxHeight = Math.max(maxHeight, firstField.getMarginTop() + firstField.getHeight() + firstField.getMarginBottom()); 
    availableWidth -= firstField.getWidth();

    maxHeight = Math.max(maxHeight, secondField.getMarginTop() + secondField.getHeight() + secondField.getMarginBottom()); 
    availableWidth -= secondField.getWidth(); 

    if(!isStyle(Field.USE_ALL_HEIGHT)) { 
     height = maxHeight; 
    } 
    if(!isStyle(Field.USE_ALL_WIDTH)) { 
     width -= availableWidth; 
    } 

    setPositionChild(_leftField, _leftField.getMarginLeft(), getFieldY(_leftField, height)); 
    setPositionChild(_rightField, width - _rightField.getWidth() - _rightField.getMarginRight(), getFieldY(_rightField, height)); 

    setExtent(width, height); 
} 

private int getFieldY(Field field, int height) 
{ 
    switch((int)((field.getStyle() & FIELD_VALIGN_MASK) >> SYSTEM_STYLE_SHIFT)) { 
     case (int)(FIELD_BOTTOM >> SYSTEM_STYLE_SHIFT): 
      return height - field.getHeight() - field.getMarginBottom(); 
     case (int)(FIELD_VCENTER >> SYSTEM_STYLE_SHIFT): 
      return field.getMarginTop() + (height - field.getMarginTop() - field.getHeight() - field.getMarginBottom())/2; 
     default: 
      return field.getMarginTop(); 
    } 
} 


public Field getLeftField() 
{ 
    return _leftField; 
} 

public Field getRightField() 
{ 
    return _rightField; 
} 

public void replace(Field oldField, Field newField) 
{ 
    if(oldField == newField) { 
     // Nothing to do 
     return; 
    } 

    if(oldField == _leftField) { 
     _leftField = newField; 
    } else if(oldField == _rightField) { 
     _rightField = newField; 
    } 
    add(newField); 
    delete(oldField); 
} 
}
