Hallo zusammen,
ich lese in meiner App eine XML-Datei aus dem Internet mit Hilfe des SaxParsers aus und lege hierbei Objekte an, die im Anschluss in einer ListView angezeigt werden.
Leider werden die Umlaute in der ListView entsprechend ihres HTML-Wertes (z.B. ü ) anstelle der deutschen Schreibweise (z.B. ü) ausgegeben.
Das richtige encoding beim Auslesen der XML-Datei habe ich gesetzt. Muss ich bei der Ausgabe auch etwas beachten?
Hier noch ein paar Code-Schnipsel:
Hier mein Handler:

Das richtige encoding beim Auslesen der XML-Datei habe ich gesetzt. Muss ich bei der Ausgabe auch etwas beachten?
Hier noch ein paar Code-Schnipsel:
Code:
/* Get a SAXParser from the SAXPArserFactory. */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
/* Get the XMLReader of the SAXParser we created. */
XMLReader xr = sp.getXMLReader();
/* Create a new ContentHandler and apply it to the XML-Reader */
FddbXmlHandler fddbXmlHandler = new FddbXmlHandler();
xr.setContentHandler(fddbXmlHandler);
InputSource is = new InputSource();
is.setEncoding("ISO-8859-1");
is.setByteStream(url.openStream());
/* Parse the xml-data from our URL. */
xr.parse(is);
/* Parsing has finished. */
/* Our Handler now provides the parsed data to us. */
return fddbXmlHandler.getParsedData();
