How to set images inside of ImageView by URL Android

Question

I found this tutorial"How to load an ImageView by URL in Android", which works fine for me, but in my case I don't want to just set a few images but a list of then, I have a Api RestFull which returns some strings and the Image URL, as I saw in that tutorial it uses a AsyncTask to download the image and set inside of ImageView, In my case I already using a AsyncTask to retrieve from my API, do I need to put something inside of my ModelClass to automatically download?

This is what I have...

public void getAdsUser(final Activity context){
    new AsyncTask<Void, Void, String>() {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }
        @Override
        protected String doInBackground(Void... voids) {
            try {
                Response = new WebBase().getUserAds(context);
                if(Response.equals("NODATA")){
                    return "NODATA";
                }
                if (Response.equals("EMPTY")){
                    return "EMPTY";
                }
                if (Response.isEmpty()){
                    return "ERROR";
                }
                else {
                    return "OK";
                }
            } catch (IOException e) {
                e.printStackTrace();
                return "ERROR";
            }
        }
        @Override
        protected void onPostExecute(String s) {
            super.onPostExecute(s);
            switch (s){
                case "NODATA":
                    GenericAlertDialog.MakeDialog(UserAds.this,R.string.NODATA);
                    break;
                case "ERROR":
                    GenericAlertDialog.MakeDialog(UserAds.this,R.string.Error_Internet);
                    break;
                case "EMPTY":
                    isVisible_ads.setVisibility(View.VISIBLE);
                    break;
                case "OK":
                    UserModelView[] modelArray = new Gson().fromJson(Response,UserModelView[].class);
                    List<UserModelView> userModelView = new ArrayList<>(Arrays.asList(modelArray));
                    adapterUserView.add(userModelView);
                    recyclerView.setAdapter(adapterUserView);
                    break;
            }
        }
    }.execute();
}

Thanks!

Make your life much easier and use Picasso.

loading images can be a simple one liner

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

See more on the site http://square.github.io/picasso/

Here is some complementary about why using Picasso is a better solution from what Stephen suggest. There are a lot of thing you need to consider like memory, caching etc. Picasso handle all of the hard work for you as long as you program it correctly and it is very simple easy to use.

You have to add Picasso library in your project and write code like this.

Picasso.with(context).load("image url").into("ImageView where you have to load image");
