我得到异常喜欢在下面的代码

IN MainActivity.java我得到异常喜欢在下面的代码

DefaultHttpClient client = new DefaultHttpClient(); 
HttpPost post = new HttpPost("http://192.168.5.10/ijoomer_development/index.php?option=com_ijoomer&plg_name=jomsocial&pview=user&ptask=login&tmpl=component"); 
StringBuffer strBuffer = new StringBuffer("<data><username>" + username + "</username><password>" + password + "</password><lat>" + lat +"</lat><long>"+ longi +"</long></data>"); 
StringEntity strEntity = new StringEntity(strBuffer.toString()); 
post.setEntity(strEntity); 
HttpResponse response = client.execute(post); 

InputStream in = response.getEntity().getContent(); 

MainActivity mActivity = new MainActivity(); 
System.out.println(mActivity.convertStreamToString(in)); 

demoHandler = new DemoHandler(); 
ArrayList<UserBean> users = demoHandler.parse(in); 
Log.i("VALUE OF USER",""+users);

IN DemoHandler.java尝试阅读靠近流

public ArrayList<UserBean> parse(InputStream in) { 
    try { 
     SAXParser parser = SAXParserFactory.newInstance().newSAXParser(); 
     parser.parse(in, this); 

    } catch (ParserConfigurationException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (SAXException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    return records; 
} 

@Override 
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException 
{ 
    data.replace(0, data.length(), ""); 

    if(localName.equalsIgnoreCase(ROOT_TAG)) 
     bean = new UserBean(); 
} 

public void characters(char[] ch, int start, int length) throws SAXException { 
    data.append(ch, start, length); 
} 

@Override 
public void endElement(String uri, String localName, String qName) throws SAXException 
{ 
    if(localName.equalsIgnoreCase(TAG_USERNAME)) 
     bean.username = data.toString().trim(); 
    else if(localName.equalsIgnoreCase(TAG_PASSWORD)) 
     bean.password = data.toString().trim(); 
    else if(localName.equalsIgnoreCase(TAG_LAT)) 
     bean.lat = data.toString().trim(); 
    else if(localName.equalsIgnoreCase(TAG_LONG)) 
     records.add(bean); 
} 

public String convertStreamToString(InputStream in) throws IOException { 
    if (in != null) { 
     writer = new StringWriter(); 

     char[] buffer = new char[1024]; 
     try { 
      Reader reader = new BufferedReader(new InputStreamReader(in, "UTF-8")); 
      int n; 
      while ((n = reader.read(buffer)) != -1) { 
       writer.write(buffer, 0, n); 
      } 
      } finally { 
       in.close(); 
      } 
      return writer.toString(); 
     } else {  
      return ""; 
     } 
    } 
}

我在MainActivity.java

得到错误的行 ArrayList<UserBean> users = demoHandler.parse(in);

我在DemoHandler.java上收到parser.parse(in, this);处的另一个错误

你的convertStreamToString方法是什么？ – Olegas 2011-03-19 06:15:59

我已编辑代码现在，我也给你在这里的方法.. – shripal 2011-03-19 06:25:15

public String convertStreamToString（InputStream in） throws IOException {if（in！= null）{ Writer writer = new StringWriter（）; char [] buffer = new char [1024]; 尝试读取器读取器=新的BufferedReader（新的InputStreamReader（in，“UTF-8”））; int n; （（n = reader.read（buffer））！= -1）write.write（buffer，0，n）; } } finally { in.close（）; } return writer.toString（）; } else { return“”; } } – shripal 2011-03-19 06:27:22

好了，我看你把这个第一：

System.out.println(mActivity.convertStreamToString(in));

假设相同converSTreamToSTring如下面的DemoHandler，这个函数调用

in.close();

所以你现在已经关闭了。正如错误说，你想在这一行以后做的东西与流：

ArrayList<UserBean> users = demoHandler.parse(in);

所以我并不感到惊讶，你所得到的java.io.IOException: Attempted read on closed stream.错误。因为你先关闭了流，然后试着用它做点什么。

k ...我明白是什么问题..但要解决它，我该怎么办？ – shripal 2011-03-19 06:47:30

那么，你有一个你想要使用的流。只要你想使用它，不要关闭它。？从它的位置（太早）删除'in.close（）'语句并将它放在其他地方。就像你在主要活动一样。 – Nanne 2011-03-19 06:49:38

ya朋友我已经从convertStreamToString方法中删除了finally并没有得到该异常bt gettintin另一个异常没有实体找到并得到相同的行错误 – shripal 2011-03-19 06:53:24

我最近有类似的问题，我通过在我的函数结束时删除method.releaseConnection()来修复它。可以帮助别人！
