I have a xmlParser where i am parsing the data in my main class i am showing in a listview the parsed data. My problem is that i am not getting the logo. How to get that ? Please tell me if i have to change in code:This is my main class\[code\]// All static variables static final String URL = "http://192.168.1.112/dineout/index.php/dineout/view"; // XML node keys static final String KEY_ITEM = "element"; // parent node //static final String KEY_ID = "foodjoint_id"; static final String KEY_NAME = "foodjoint_name"; static final String KEY_LOGO = "logo"; //static final String KEY_DESC = "foodjoint_description"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>(); XMLParser parser = new XMLParser(); String xml = parser.getXmlFromUrl(URL); // getting XML Document doc = parser.getDomElement(xml); // getting DOM element NodeList nl = doc.getElementsByTagName(KEY_ITEM); // looping through all item nodes <item> for (int i = 0; i < nl.getLength(); i++) { // creating new HashMap HashMap<String, String> map = new HashMap<String, String>(); Element e = (Element) nl.item(i); // adding each child node to HashMap key => value //map.put(KEY_ID, parser.getValue(e, KEY_ID)); map.put(KEY_NAME, parser.getValue(e, KEY_NAME)); map.put(KEY_LOGO, parser.getValue(e, KEY_LOGO)); //map.put(KEY_DESC, parser.getValue(e, KEY_DESC)); // adding HashList to ArrayList menuItems.add(map); } // Adding menuItems to ListView ListAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.list_item, new String[] { KEY_NAME, KEY_LOGO }, new int[] { R.id.name,R.id.imageView1 }); setListAdapter(adapter); // selecting single ListView item ListView lv = getListView(); lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // getting values from selected ListItem String name = ((TextView) view.findViewById(R.id.name)).getText().toString(); String cost = ((TextView) view.findViewById(R.id.cost)).getText().toString(); String description = ((TextView) view.findViewById(R.id.desciption)).getText().toString(); // Starting new intent Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class); in.putExtra(KEY_NAME, name); in.putExtra(KEY_LOGO, cost); //in.putExtra(KEY_DESC, description); startActivity(in); } }); }}\[/code\]This is my parser class\[code\]public class XMLParser { // constructor 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(); 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)); }\[/code\]
