获取列表项的行包，而不是显示省略号 [英] Get list item row to wrap instead of show ellipsis

问题描述

我用code下面让产生格式图像，标题和列表项文本区域的布局。结果
我想获得它看起来像Twitter的应用程序布局 - 在它是如何得到鸣叫包，什么条件我缺少

平台详细信息：
BB OS 5.0 +

code：

 保护无效sublayout（INT宽度，高度INT）{
    尝试{
        删除所有（）;
    }赶上（例外前）{    }    MyTitleField lblTitle =新MyTitleField（info.title）; //扩展的LabelField
    lblDesc的LabelField =新的LabelField（info.description，LabelField.ELLIPSIS）
    {
        保护无效布局（INT宽度，高度INT）{
            // TODO自动生成方法存根
            super.layout（宽度，高度）;
        }
    };    BitmapField bmfIcon =新BitmapField（info.icon）;
    加（lblTitle）;
    加（lblDesc）;
    加（bmfIcon）;    INT iconHeight = bmfIcon.getBitmapHeight（）;
    INT fontHeight = Font.getDefault（）的getHeight（）。
    INT preferredWidth =宽度; //获取preferredWidth（）;    INT startY =（的rowHeight  -  iconHeight）/ 2;
    layoutChild（bmfIcon，bmfIcon.getBitmapWidth（），bmfIcon.getBitmapHeight（））;
    setPositionChild（bmfIcon，5，startY）;    INT输出textWidth = preferredWidth  - （bmfIcon.getBitmapWidth（）+10）;
    INT textStartX = bmfIcon.getBitmapWidth（）+ 10;
    layoutChild（lblTitle，输出textWidth，
            fontHeight + 1）;
    setPositionChild（lblTitle，textStartX，startY）;    INT descHeight =的rowHeight  - （startY + fontHeight + 2）;
    layoutChild（lblDesc，输出textWidth，descHeight）;    setPositionChild（lblDesc，textStartX，（startY + fontHeight + 2））;    setExtent（preferredWidth，GET preferredHeight（））;
}
 

解决方案

1. 首先，你需要为icchanobot建议摆脱省略号风格。


2. 然后你需要添加在 VerticalFieldManager （ Horizo​​ntalFieldManager 将工作太）在建议<你的标签字段A HREF =htt​​p://stackoverflow.com/a/6435717/396949>这个答案。

以下code段

 字符串longString =这是一个VerticalFieldManager内的LabelField。这是你的问题http://stackoverflow.com/questions/7641753/get-list-item-row链接-to-总结INSTEAD-OF-秀-省略号VerticalFieldManager VFM =新VerticalFieldManager（Manager.USE_ALL_WIDTH | Manager.NO_HORIZONTAL_SCROLL）;
vfm.add（新的LabelField（longString））;
加（VFM）;
 

结果
产生

I used the code below to get produce a layout that formats an image, a title and a text region in a list item.
I would like to get it to look like the Twitter apps layout - in terms of how it gets the tweet to wrap, what am I missing?

Platform details: BB OS 5.0+

Code:

protected void sublayout(int width, int height) {
    try {
        deleteAll();
    } catch (Exception ex) {

    }

    MyTitleField lblTitle = new MyTitleField(info.title);//extends LabelField
    LabelField lblDesc = new LabelField(info.description , LabelField.ELLIPSIS)
    {
        protected void layout(int width, int height) {
            // TODO Auto-generated method stub
            super.layout(width, height);
        }
    };

    BitmapField bmfIcon = new BitmapField(info.icon);
    add(lblTitle);
    add(lblDesc);
    add(bmfIcon);

    int iconHeight = bmfIcon.getBitmapHeight();
    int fontHeight = Font.getDefault().getHeight();
    int preferredWidth = width;//getPreferredWidth();

    int startY = (rowHeight - iconHeight)/2;
    layoutChild(bmfIcon, bmfIcon.getBitmapWidth(), bmfIcon.getBitmapHeight());
    setPositionChild(bmfIcon, 5, startY);

    int textWidth  = preferredWidth - (bmfIcon.getBitmapWidth() +10 );
    int textStartX = bmfIcon.getBitmapWidth() + 10;
    layoutChild(lblTitle, textWidth  ,
            fontHeight + 1);
    setPositionChild(lblTitle, textStartX, startY);

    int descHeight = rowHeight - (startY+fontHeight+2);
    layoutChild(lblDesc, textWidth  , descHeight);

    setPositionChild(lblDesc, textStartX, (startY+fontHeight+2));

    setExtent(preferredWidth, getPreferredHeight());
}

解决方案

1. First, you need to get rid of ELLIPSIS style as icchanobot suggested.
2. Then you need to add your label field inside a VerticalFieldManager (HorizontalFieldManager will work too) as suggested in this answer.

The following code snippet

String longString = "This is a LabelField inside a VerticalFieldManager. Here is a link to your question http://stackoverflow.com/questions/7641753/get-list-item-row-to-wrap-instead-of-show-ellipsis";

VerticalFieldManager vfm = new VerticalFieldManager(Manager.USE_ALL_WIDTH | Manager.NO_HORIZONTAL_SCROLL);
vfm.add(new LabelField(longString));
add(vfm);

produces
