Custom Listview with Text and image


I have developed a listview,listview displaying image and text.1st have to download image and text form web-service then have to display because it takes more time so we thought 1st bind text in listview and use AsyncTaskand as soon as image download image will be shown in the listview in the background of activity.But i'm unable to do that i have done some coding and it download all image and then bind both image and text(in this case we need to bind listview two times 1st before startDownload image and 2nd after download image.So if any has some idea please suggest me.


public class LoadImg extends AsyncTask<String, Void, Bitmap> { Context context; String img; InputStream is = null; Bitmap bitmap = null; public LoadImg(Context context, String img) { // TODO Auto-generated constructor stub this.context = context; this.img = img; } @Override protected Bitmap doInBackground(String... params) { // TODO Auto-generated method stub Bitmap bitmap = downImg(); System.out .println("Value of bitmap=====================================" + bitmap); return bitmap; } private Bitmap downImg() { // TODO Auto-generated method stub Bitmap bitmap = null; if (img == null) { bitmap = null; } else { URL url = null; try { url = new URL(img); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } URLConnection connection = null; try { connection = url.openConnection(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } try { is = connection.getInputStream(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } bitmap = BitmapFactory.decodeStream(is); System.out.println("TV Image===" + bitmap); } return bitmap; } }


Try this <a href="http://www.androidchennai.blogspot.in/2012/03/android-listview-example.html" rel="nofollow">example</a> or use any adapter like this



</blockquote> public class WeatherAdapter extends ArrayAdapter<Weather>{ Context context; int layoutResourceId; Weather data[] = null; public WeatherAdapter(Context context, int layoutResourceId, Weather[] data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; WeatherHolder holder = null; if(row == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); row = inflater.inflate(layoutResourceId, parent, false); holder = new WeatherHolder(); holder.imgIcon = (ImageView)row.findViewById(R.id.imgIcon); holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle); row.setTag(holder); } else { holder = (WeatherHolder)row.getTag(); } Weather weather = data[position]; holder.txtTitle.setText(weather.title); holder.imgIcon.setImageResource(weather.icon); return row; } static class WeatherHolder { ImageView imgIcon; TextView txtTitle; } }
