如何在Android中阅读并填充ListView，我该怎么办：DOM，XML Parser或SAX ??

Answer 1

对于像这样的小小片段，我更喜欢DOM。

String xml;
Document doc;
Element root = null;
try {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    doc = builder.parse( new InputSource( new StringReader( xml ) ) );
    root = doc.getDocumentElement();
} catch ( Exception e ) {
    // do something
}

if( root != null ) {
    NodeList cats = root.getElementsByTagName( "category" );
    for( int i=0; i < cats.getLength(); i++ ) {
    Element category = (Element)cats.item( i );
        ....
    }
}
