检查响应的内容类型标头的字符集。它可以是 ISO-8859-1 或 UTF-8。相应地编码。
编辑：对于您提供的链接，我没有为响应设置任何编码。既然您提到您是 XML 解析的新手，我将发布我的解析器实现。
我的解析器：
public final class SampleParser{
final static String ROOT_NODE = "Menus";
final static String ELEMENT_SITEMENU = "SiteMenu";
final static String ELEMENT_ID = "menuID";
final static String ELEMENT_TITLE = "menuTitle";
final static String ELEMENT_CUSTOM = "menuIsCustom";
final static String ELEMENT_PAGE_URL = "menuCustomPageURL";
final static String ELEMENT_IOS_ID = "iosMenuID";
private static final String TAG="SampleParser";
/**
* Intentionally commented
*/
private SampleParser() {}
/**
* @param response The XML string which represents the complete news data
* @return news The complete data
*/
public static Menus parse(String response) {
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp;
try {
sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
SampleDataHandler dataHandler = new SampleDataHandler();
xr.setContentHandler(dataHandler);
InputSource source = new InputSource(new StringReader(response));
xr.parse(source);
Menus result = dataHandler.getData();
return result;
} catch (ParserConfigurationException e) {
Log.e(TAG, "parse", e);
} catch (SAXException e) {
Log.e(TAG, "parse", e);
} catch (IOException e) {
Log.e(TAG, "parse", e);
}
return null;
}
static class SampleDataHandler extends DefaultHandler {
/**

/**

public Menus getData(){
return data;
}

}
/*

@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
String chars = new String(ch, start, length);
chars = chars.trim();
if(readingID){
try{
tempElement.setId(Integer.parseInt(chars));
}catch(Exception e){
Log.e(TAG, "characters[Parsing ID]", e);
tempElement.setId(-1);
}
}
else if(readingIosId){
try{
tempElement.setiOSID(Integer.parseInt(chars));
}catch(Exception e){
Log.e(TAG, "characters[Parsing iOSID]", e);
tempElement.setiOSID(-1);

Log.e(TAG, "characters[Parsing custom]", e);
tempElement.setCustom(false);
}
}else if(readingCustomURL){
tempElement.setCustomUrl(chars);
}
}
}
}
我用于网络调用的 utils 方法。[和你一样]
/**
* @param url
* @return
*/
private static HttpEntity getResponseEntity(String url) {
DefaultHttpClient httpClient = getHttpClient();
HttpGet getMethod = new HttpGet(url);
long startTime= 0;
try {
HttpResponse httpResponse = httpClient.execute(getMethod);
HttpEntity responseEntity = httpResponse.getEntity();
return responseEntity;
} catch (IOException ioe) {
Log.e(TAG, "getResponseEntity", ioe);
} catch (Exception e) {
Log.e(TAG, "getResponseEntity", e);
}
return null;
}
/**
* @param url
* @return
*/
public static String getRespAsString(String url) {
if (!ApplicationInfo.networkStatus) {
// No Internet Connection
return null;
}
try {
HttpEntity responseEntity = getResponseEntity(url);
if (responseEntity != null)
return EntityUtils.toString(responseEntity);
else
return null;
} catch (Exception e) {
Log.e(TAG, "getRespAsString", e);
}
return null;
}
只需获取响应并调用解析器，例如。SampleParser.parse(response);
