Code Snippet For Android Intent

ListView  to display data and onclick to move to new Intent

*****************************************************************

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_COST, "Rs." + parser.getValue(e, KEY_COST));

            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_DESC, KEY_COST }, new int[] {

                        R.id.name, R.id.desciption, R.id.cost });

        setListAdapter(adapter);

        // selecting single ListView item

        ListView lv = getListView();

                // listening to single listitem click

        lv.setOnItemClickListener(new OnItemClickListener() {

                    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
