解析rss和atom文件出现乱码问题

try {
String xmlString = new String(response.data, Charset.forName("UTF-8"));
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
XmlPullParser xmlPullParser = factory.newPullParser();
xmlPullParser.setInput(new StringReader(xmlString));
return Response.success(xmlPullParser, HttpHeaderParser.parseCacheHeaders(response));
} catch (XmlPullParserException e) {
return Response.error(new ParseError(e));
}
