我通过使用HTTP-post发送值，但是我的代码出现异常： -
public static InputStream SendDetails(String senderEmail,String senderName,String senderPhone,String comment )
{
if(item != null)
{
url = constants.STATEURL + item.getListingid().toString()+"/contact";//?access_token=0|V1CALGARY|e98984a4c954fa1d78e3be626ad81a1d&mode=map";
}
else if(itemsavedfromdb != null)
{
url = constants.STATEURL + itemsavedfromdb.getListingid().toString()+"/contact";//?access_token=0|V1CALGARY|e98984a4c954fa1d78e3be626ad81a1d&mode=map";
}
else if(itemrecentfromdb != null)
{
url = constants.STATEURL + itemrecentfromdb.getListingid().toString()+"/contact";//?access_token=0|V1CALGARY|e98984a4c954fa1d78e3be626ad81a1d&mode=map";
}
List<BasicNameValuePair> nameValuePairs = new ArrayList<BasicNameValuePair>();
nameValuePairs.add(new BasicNameValuePair("access_token",constants.accesstokenstate));
nameValuePairs.add(new BasicNameValuePair("mode","map"));
nameValuePairs.add(new BasicNameValuePair("senderEmail",senderEmail));
nameValuePairs.add(new BasicNameValuePair("senderName",senderName));
nameValuePairs.add(new BasicNameValuePair("senderPhone",senderPhone));
nameValuePairs.add(new BasicNameValuePair("comment",comment));
HttpPost request = new HttpPost(url);
request.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(request);
return response.getEntity().getContent();
} 这个方法叫做： -
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
mailHandler myhandler = new mailHandler();
xr.setContentHandler(myhandler);
String mailID = youremail.getText().toString();
if(mailID != null && !mailID.equalsIgnoreCase("") )
{
System.out.println("1");
ios = SendDetails(mailID,yourName.getText().toString(),yourPhoneNo.getText().toString(),yourMessage.getText().toString());
System.out.println("ios-----"+ios);
String strResponse = convertStreamToString(ios);
System.out.println("response"+strResponse);
xr.parse(new InputSource(ios));
resultmail = myhandler.emailresultdata();
customizeDialog = new CustomizeDialog(PropertyDetail.this);
customizeDialog.setTitle("Success");
customizeDialog.setMessage("Email send successfully");
customizeDialog.show();
由于哪些数据未成功发送，代码会出现在代码之上

和我的convertStreamToString方法如下： -
private static String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return sb.toString();
}
任何人都建议我在哪里做错了，这是怎么回事。

好的，从
更改您的代码xr.parse(new InputSource(ios));
到
InputStream input = new ByteArrayInputStream(strResponse.getBytes());
xr.parse(new InputSource(input));
答案 1 :(得分：0)
您正在将输入流传递给convertStreamToString方法，并且您正在该方法中关闭相同的输入流实例。在该方法之后，您仍然使用相同的流实例。这就是你得到这个例外的原因。
在convertStreamToString方法中创建一个输入流的局部变量，如下所示。
private static String convertStreamToString(InputStream is) {
InputStream inputStream = is;
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
inputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return sb.toString();
}
试试这个。

阅读我关于在单独的线程上执行网络连接的博文。在AsyncTask或Thread中包含请求通常会解决问题。它还使您的应用程序响应更快，并且更不容易出现ANR强制关闭对话框。
