flex text换行

flex中字符换行存在两种情况，要区别对待

1.在MXML中，要用? 

?

eg:

<mx:Text id="tt" width="75%" height="100%" x="{line.x}" y="4"
????? text="派车提醒：0102 &#xa;用车时间：2012-5-2 15:30 &#xa; Ntt.cc was created br Minidxer in January of 2008 as a site dedicated to the prolification of Macromedia/Adobe Flex and JavaScript/Ajax.fdggjfsdfjosafgfsjagogogoerg bfdsjf">

?

2.在as中，则可以使用? n,

eg:temp=temp+"n"+mApi.NewsDP.getItemAt(i).Type+"："+mApi.NewsDP.getItemAt(i).NewsText+"n"+"时间："+mApi.NewsDP.getItemAt(i).Time;
