java.io.ioexception试图在封闭流中读取

我是android world的新手。我试图了解客户端和服务器连接，所以我编写了一个程序，但它显示我java.io.ioexception尝试读取关闭流和在我的Logat它显示我整个HTML页当我打印转换respose。这里是我的代码java.io.ioexception试图在封闭流中读取

private class getDataFromDatabse extends AsyncTask<String, String, String> { 

     boolean switchintent=false; 
     String busStopNme; 
     private ProgressDialog pDialog; 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 

      pDialog = new ProgressDialog(WelcomeActivity.this); 
      pDialog.setMessage("Getting Data ..."); 
      pDialog.setIndeterminate(false); 
      pDialog.setCancelable(true); 
      pDialog.show(); 

     } 

     @Override 
     protected String doInBackground(String... params) { 
      try { 
       // TODO Auto-generated method stub 
       HttpClient httpclient = new DefaultHttpClient(); 
       System.out.println("IP is " + IP); 
       HttpPost httppost = new HttpPost("http://" + IP + "/connection.php"); 
       /*List<BasicNameValuePair> nameValuePairs = new ArrayList<BasicNameValuePair>(1); 
       nameValuePairs.add(new BasicNameValuePair("BusStopName","thakur_complex")); 
       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));*/ 
       System.out.println(httppost); 
       Log.e("welocmeActivity", "HTTPPost is " + httppost.getURI()); 
       HttpResponse response = httpclient.execute(httppost); 
       HttpEntity entity = response.getEntity(); 
       is = entity.getContent(); 
       System.out.println("top of convert string"); 
       String tempValue = convertString(is); 
       System.out.println(tempValue); 
       if (convertString(is) == "succeed") { 

        busStopNme = "Thakur Complex"; 
        switchintent=true; 

       } 
       System.out.println(is.toString()); 
       System.out.println("bottom of convert string"); 
      } catch (Exception e) { 
       // TODO: handle exception 
       System.out.println("Exception" +e); 
       e.printStackTrace(); 
      } 

      return busStopNme; 
     } 

     private String convertString(InputStream is) { 

      BufferedReader reader; 
      try { 
       reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"), 8); 

       sb = new StringBuilder(); 
       sb.append(reader.readLine() + "\n"); 
       String line = "0"; 

       while ((line = reader.readLine()) != null) { 
        sb.append(line + "\n"); 
       } 

       reader.close(); 
       busStopNme = sb.toString(); 
      } catch (Exception e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      return busStopNme; 
     }

和我logcat的文件是在这里为遵循..

请阅读以下博客。从url获取数据http://www.androidhive.info/2012/01/android-json-parsing-tutorial/ – prakash

手机可以只用xml或json – prakash

在方法convertString你关闭阅读器 - reader.close();关闭strea米

试试这个

删除此行

String tempValue = convertString(is); 
System.out.println(tempValue); 
System.out.println(is.toString());
