In my application i have an listview ..Each row contains an image and a textview in relative layout..Everything is done..But the listview is not scrolling that much smooth as native "Contact list".I think the problem lies in getview(),y because in this method i have a "HTTP" call and bitmap image loading..Is there anyway to do this..Please help me..thanks in advance..
My Getview method:
public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub Bitmap bitmap = DownloadImage( kickerimage[position] ); // View listView = convertView; ViewHolder holder; if (convertView == null) { //this should only ever run if you do not get a view back LayoutInflater inflater = (LayoutInflater) contxt .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.homelistrow, null); holder = new ViewHolder(); holder.image = (ImageView) convertView .findViewById(R.id.icon); holder.image.setImageBitmap(bitmap); holder.text = (TextView) convertView .findViewById(R.id.name_label); holder.text.setText(itemsarray[position]); } return convertView ; } private Bitmap DownloadImage(String URL) { // System.out.println("image inside="+URL); Bitmap bitmap = null; InputStream in = null; try { in = OpenHttpConnection(URL); bitmap = BitmapFactory.decodeStream(in); in.close(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } // System.out.println("image last"); return bitmap; } private InputStream OpenHttpConnection(String urlString) throws IOException { InputStream in = null; int response = -1; URL url = new URL(urlString); URLConnection conn = url.openConnection(); if (!(conn instanceof HttpURLConnection)) throw new IOException("Not an HTTP connection"); try{ HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(false); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); response = httpConn.getResponseCode(); if (response == HttpURLConnection.HTTP_OK) { in = httpConn.getInputStream(); } } catch (Exception ex) { throw new IOException("Error connecting"); } return in; }
