Use asyncTask to load images

Question

i m loading images from rss description using

String description2 = des.get(position).toString();

       Spanned description = Html.fromHtml(description2, new ImageGetter() {
            @Override
         public Drawable getDrawable(String source) {                  
            Drawable d = null;
            try {
                        InputStream src = imageFetch(source);
                        d = Drawable.createFromStream(src, "src");
                        if(d != null){
        d.setBounds(0,0,d.getIntrinsicWidth(),
        d.getIntrinsicHeight());
                        }
        } catch (MalformedURLException e) {
                  e.printStackTrace(); 
            } catch (IOException e) {
                  e.printStackTrace();  
            }

        return d;
        }

            public InputStream imageFetch(String source)
                    throws MalformedURLException,IOException {
        URL url = new URL(source);
        Object o = url.getContent();
        InputStream content = (InputStream)o;
        // add delay here (see comment at the end)     
        return content;
        }

        },null);

How can i put them into an AsyncTask,in order to get a progress bar until the images download? Thanks!

Look at [Android HTML ImageGetter as AsyncTask](http://stackoverflow.com/questions/7424512/android-html-imagegetter-as-asynctask) — user370305, Dec 24 '11 at 14:34

You can take a look at this tutorial, which downloads images from the web and uses progress bar. All done in AsyncTask and the complete source is available.

you can use this WebImageView from generic-store-for-android

which is adapted from droid-fu project.

here is an example usage;
-> define inside your layout

<com.wareninja.opensource.droidfu.widgets.WebImageView
  android:id="@+id/img_fbProfilePic"
  android:visibility="visible"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
/>

-> set the url to load

WebImageView fbProfilePic = (WebImageView) this.findViewById(R.id.img_fbProfilePic);
fbProfilePic.setImageUrl("http://graph.facebook.com/100001789213579/picture");
fbProfilePic.loadImage();
