a.

先看下这个xml文件的内容:

  <?xml version="1.0" encoding="UTF-8" ?> 

<videonews>

 <news id="35">

  <title>喜洋洋喜洋洋</title> 

  <timelength>90</timelength> 

  </news>

 <news id="20">

  <title>李德伟大侠</title> 

  <timelength>15</timelength> 

  </news>

 <news id="50">

  <title>马长海和莉莉</title> 

  <timelength>16</timelength> 

  </news>

  </videonews>

------------------------------------------------------------------------------------------

 报了这个错误，这个地方是由于多加了一个：

   private static  List<News> parseXML(InputStream inStream)throws Exception

{

List<News> newses=new ArrayList<News>();

News news=null;

XmlPullParser parser=Xml.newPullParser();

parser.setInput(inStream, "UTF-8");

int event=parser.getEventType();

while(event!=XmlPullParser.END_DOCUMENT){

//event=parser.next();//原因是这个地方原来没有被注释掉，这样的话，他会一个节点一个节点的读那么第一个节点读出来的就是：<videonews>这样的话，下面的代码就 

               //没法执行了,

                //所以就报了下面的错误:private static  List<News> parseXML(InputStream inStream)throws Exception

{

List<News> newses=new ArrayList<News>();

News news=null;

XmlPullParser parser=Xml.newPullParser();

parser.setInput(inStream, "UTF-8");

int event=parser.getEventType();

while(event!=XmlPullParser.END_DOCUMENT){

//event=parser.next();

switch (event)

{

case XmlPullParser.START_TAG://如果不用event=parser.next(),而直接判断的话,那么解析是从<news 开始的,这样才是正确的.

if("news".equals(parser.getName())){

int id= new Integer(parser.getAttributeValue(0));

news=new News();

news.setId(id);

}else if("title".equals(parser.getName())){

news.setTitle(parser.nextText());

}else if("timelength".equals(parser.getName())){

news.setTimelength(new Integer(parser.nextText()));

}

break;

case XmlPullParser.END_TAG:

if("news".equals(parser.getName())){

newses.add(news);

news=null;

}

break;

}

event=parser.next();

}

return newses;
