How to set image from Url using AsyncTask?

Question

I\'m a newbie programmer an I\'m making an android program that displays an image on ImageView from a given url. My problem is how do you use this on the AsyncTask?

Answer 1

If the image is not that big you can just use an anonymous class for the async task. This would like this:

ImageView mChart = (ImageView) findViewById(R.id.imageview);
String URL = "http://www...anything ...";

mChart.setTag(URL);
new DownloadImageTask.execute(mChart);

and the task class is

public class DownloadImagesTask extends AsyncTask {
   ImageView imageView = null;
   @Override
   protected Bitmap doInBackground(ImageView... imageViews) {
      this.imageView = imageViews[0];
      return download_Image((String)imageView.getTag());
   }

   @Override
   protected void onPostExecute(Bitmap result) {
      imageView.setImageBitmap(result);
   }

   private Bitmap download_Image(String url) {
       ...
   }
