Android - การดึง ภาพ จาก rss มาลงใน listview ช่วยแนะนำหน่อยคับ

headlines = new ArrayList();
		links = new ArrayList();

		try {
			URL url = new URL("http://www.bangkokbiznews.com/home/services/rss/home.xml");

			XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
			factory.setNamespaceAware(false);
			XmlPullParser xpp = factory.newPullParser();

		        // We will get the XML from an input stream
			xpp.setInput(getInputStream(url), "UTF_8");

			boolean insideItem = false;

		        // Returns the type of current event: START_TAG, END_TAG, etc..
			int eventType = xpp.getEventType();
			while (eventType != XmlPullParser.END_DOCUMENT) {
				if (eventType == XmlPullParser.START_TAG) {

					if (xpp.getName().equalsIgnoreCase("item")) {
						insideItem = true;
					} else if (xpp.getName().equalsIgnoreCase("title")) {
						if (insideItem)
							headlines.add(xpp.nextText()); //extract the headline
					} else if (xpp.getName().equalsIgnoreCase("link")) {
						if (insideItem)
							links.add(xpp.nextText()); //extract the link of article
					}
				}else if(eventType==XmlPullParser.END_TAG && xpp.getName().equalsIgnoreCase("item")){
					insideItem=false;
				}

				eventType = xpp.next(); //move to next element
			}

		} catch (MalformedURLException e) {
			e.printStackTrace();
		} catch (XmlPullParserException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}

		// Binding data
		ArrayAdapter adapter = new ArrayAdapter(this,
				android.R.layout.simple_list_item_1, headlines);

		setListAdapter(adapter);
