我想寫解析XML代碼的代碼，並在列表視圖中寫的每個節點的值XML解析的Android
我與這個XML

工作我嘗試按照本教程
http://www.androidhive.info/2011/11/android-xml-parsing-tutorial
，但沒有工作
任何幫助，請:(
這是XMLParser中的代碼
公共XMLParser類{
public XMLParser() {
}
/**
* Getting XML from URL making HTTP request
*
* @param url
* string
* */
public String getXmlFromUrl(String url) {
String xml = null;
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
xml = EntityUtils.toString(httpEntity);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// return XML
return xml;
}
/**
* Getting XML DOM element
*
* @param XML
* string
* */
public Document getDomElement(String xml) {
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
// dbf.setCoalescing(true);
try {
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xml));
doc = db.parse(is);
} catch (ParserConfigurationException e) {
Log.e("Error: ", e.getMessage());
return null;
} catch (SAXException e) {
Log.e("Error: ", e.getMessage());
return null;
} catch (IOException e) {
Log.e("Error: ", e.getMessage());
return null;
}
return doc;
}
/**
* Getting node value
*
* @param elem
* element
*/
public final String getElementValue(Node elem) {
Node child;
if (elem != null) {
if (elem.hasChildNodes()) {
for (child = elem.getFirstChild(); child != null; child = child
.getNextSibling()) {
if (child.getNodeType() == Node.TEXT_NODE) {
return child.getNodeValue();
}
}
}
}
return "";
}
/**
* Getting node value
*
* @param Element
* node
* @param key
* string
* */
public String getValue(Element item, String str) {
NodeList n = item.getElementsByTagName(str);
return this.getElementValue(n.item(0));
}
}
，這是在MainActivity的代碼

請出示你已經嘗試了代碼，並在那裏你遇到問題明確告訴我們。 –
發佈你的代碼，你已經做了什麼，你已經做了什麼，你的logcat輸出。沒有這些，社區中沒有人可以幫助你。 –
_但沒有什麼work_是不是很有幫助的傢伙。發佈你迄今爲止工作過的代碼。 –
