首先，我是这个java / android开发世界的新手，所以对我来说很遗憾，我可能会问一些相对新手的问题:)。 无论如何，我现在一整天都在解决这个问题，而且我无法通过自己找出任何解决方案，而且我在网上搜索能够绕过这个问题的想法。
我正在尝试开发一个解析外部XML文件数据的Android应用程序。
我的解析器看起来像这样：
public class NewSAXHandler implements ContentHandler
{
private String DEBUGTAG = "NewSAXHandler";
public static setNews news = null;
boolean currentElement = false;
String currentValue = null;
public static setNews getNews()
{
return news;
}
public static void setNewsList(setNews news)
{
NewSAXHandler.news = news;
}
@Override
public void startDocument() throws SAXException {
// TODO Auto-generated method stub
}
@Override
public void endDocument() throws SAXException {
// TODO Auto-generated method stub
}
@Override
public void startElement(String uri, String localName, String qname, Attributes attr) throws SAXException
{
currentElement = true;
if (localName.equalsIgnoreCase("channel"))
news = new setNews();
Log.d(DEBUGTAG, localName);
}
@Override
public void endElement(String uri, String localName, String qName) throws SAXException
{
if (localName.equalsIgnoreCase("title"))
{
news.setHeadline(currentValue);
Log.d(DEBUGTAG, localName);
Log.d(DEBUGTAG, currentValue);
}
else if (localName.equalsIgnoreCase("pubdate"))
{
news.setDate(currentValue);
Log.d(DEBUGTAG, localName);
Log.d(DEBUGTAG, currentValue);
}
}
@Override
public void characters(char[] ch, int start, int length) throws SAXException
{
if (currentElement)
{
currentValue = new String(ch, start, length).replaceAll("\\r\\n|\\r|\\n", " ");
currentElement = false;
}
}
@Override
public void ignorableWhitespace(char[] ch, int start, int length)throws SAXException
{
}
@Override
public void endPrefixMapping(String prefix) throws SAXException
{
}
@Override
public void processingInstruction(String target, String data)throws SAXException
{
}
@Override
public void setDocumentLocator(Locator locator)
{
}
@Override
public void skippedEntity(String name) throws SAXException
{
}
@Override
public void startPrefixMapping(String prefix, String uri)throws SAXException
{
}
}

似乎错误来自'角色 我看不到编码，因为它不在XML文件中，但我猜它是UTF-8 我也尝试使用StringBuilder来存储每个角色而没有任何运气。
我认为XML解析器会自行转换这些特殊字符，但似乎它不喜欢它。
如果我尝试解析此文件：
http://www.hltv.org/forum.rss.php然后它会更好。
有人有任何新想法吗？
**如果您需要我的代码，请说出来：）
最诚挚的问候，

答案 0 :(得分：2)
问题是Philipp上面说的编码。
我刚刚在我的代码中添加了以下内容：
InputSource is = new InputSource(url.openStream());
is.setEncoding("ISO-8859-1");
Reader.parse(is);
