如何在单屏幕上显示blackberry中的两个数据

嗨，朋友，我如何在一个屏幕上显示黑莓手机中的两个数据。 例如：

公共LabelField lbSr、lbDate、lbAllo、lbMob、lbDetail、lbRemark、lbSlaDate、lbEmail、lbStatus、lbspace； 公共LabelField lb1Sr、lb1Date、lb1Allo、lb1Mob、lb1Detail、lb1Remark、lb1SlaDate、LB1Mail、lb1Status； 公开证明的水平油田经理jhfm1、jhfm2、jhfm3、jhfm4、jhfm5、jhfm6、jhfm7、jhfm8、jhfm9； VerticalFieldManager vfm=新建VerticalFieldManager服务器TicalFieldManager.VERTICAL\u滚动； lb1Sr=新的LabelFieldSRNo:； lb1Sr.setColorColor.BLACK； lbSr=新的LabelFieldsStrerno； lbSr.setColorColor.BLACK； lb1Date=新的LabelFieldSRDate:； lb1Date.setColorColor.BLACK； lbDate=新的LabelFieldsRDATE； lbDate.setColorColor.BLACK； lb1Allo=新的LabelFieldLocDate:； lb1Allo.setColorColor.BLACK； lbAllo=新的LabelFieldstrAllo； lbAllo.setColorColor.BLACK； lb1Mob=新的LabelFieldMobNo:； lb1Mob.setColorColor.BLACK； lbMob=新的LabelFieldstrMob； lbMob.setColorColor.BLACK； lb1Detail=新标签字段详细信息：； lb1Detail.setColorColor.BLACK； lbDetail=新的LabelFieldsRDETail； lbDetail.setColorColor.BLACK； lb1Remark=新的LabelFieldMarks:； lb1Remark.setColorColor.BLACK； lbRemark=新的LabelFieldsTREMARK； lbRemark.setColorColor.BLACK； lb1SlaDate=新的LabelFieldSLADate:； LB1slade.setColorColor.BLACK； lbSlaDate=新的LabelFieldstrSldate； lbSlaDate.setColorColor.BLACK； lb1Email=新的LabelFieldEmail:； lb1Email.setColorColor.BLACK； lbEmail=新的labelfieldsremail； lbEmail.setColorColor.BLACK； lb1Status=新的LabelFieldStatus:； lb1Status.setColorColor.BLACK； lbStatus=新的LabelFieldstrStatus； lbStatus.setColorColor.BLACK； jhfm1=新的合理水平现场管理器RLB1SR，lbSr，真； vfm.addjhfm1； jhfm2=新的合理水平字段管理器RLB1Date、lbDate、true； vfm.addjhfm2； jhfm3=新的合理水平现场管理器RLB1ALLO，lbAllo，true； vfm.addjhfm3； jhfm4=新的合理的水平字段管理器RLB1MOB，lbMob，true； vfm.addjhfm4； hfm5=新的合理水平字段管理器RLB1detail，lbDetail，true； vfm.addjhfm5； jhfm6=新的合理的水平字段管理器RLB1remark，lbRemark，true； vfm.addjhfm6； jhfm7=新的合理水平字段管理器RLB1SLADATE，lbSlaDate，true； vfm.addjhfm7； jhfm8=新的合理的水平字段管理器RLB1email，lbEmail，true； vfm.addjhfm8； jhfm9=新的合理水平字段管理器RLB1状态，lbStatus，true； vfm.addjhfm9； addvfm； 我想使用双面滚动选项显示所有数据。

请尝试以下代码-

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);

以此类推……像这样添加所有字段

下面给出了合理的HorizontalFieldManager类-

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 );
}

public JustifiedHorizontalFieldManager( Field leftField, Field rightField, boolean giveLeftFieldPriority, long style )
{
    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();
}

{
    return Math.max( _leftField.getPreferredHeight(), _rightField.getPreferredHeight() );
}

protected void sublayout( int width, int height )
{
    Field firstField;
    Field secondField;
    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();

    layoutChild( secondField, availableWidth, height - secondField.getMarginTop() - secondField.getMarginBottom() );
    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 );
}
}

好友签名感谢重播我使用了你的代码，但垂直滚动不会产生任何影响。添加这么多项目，然后你的页面将滚动。
