Hi

I am trying to use picasso to download images into an rss feeds placeholder, but i run the project in the emulator i got the following error message in my logcat "java.lang.IllegalArgumentException: Resource ID must not be zero." see my code below

import android.content.Context;
import android.content.Intent;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;


import com.mobile.gemstouch.newsdesk365.R;
import com.mobile.gemstouch.newsdesk365.WebView;
import com.mobile.gemstouch.newsdesk365.models.RSSFeed;
import com.squareup.picasso.Picasso;

import java.util.List;

public class NewsDataAdapter extends RecyclerView.Adapter<NewsDataAdapter.FeedListRowHolder> {

    private List<RSSFeed> feedItemList;
    private Context mContext;

    public NewsDataAdapter(Context context, List<RSSFeed> feedItemList) {
        this.feedItemList = feedItemList;
        this.mContext = context;
    }

    @Override
    public FeedListRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.cardview_row, null);
        FeedListRowHolder mh = new FeedListRowHolder(v);
        return mh;
    }

    @Override
    public void onBindViewHolder(FeedListRowHolder feedListRowHolder, int i) {
        RSSFeed feedItem = feedItemList.get(i);

        //Download image using picasso library
        Picasso.with(mContext).load(feedItem.getThumbImage())
                .error(R.drawable.list_placeholder)
                .placeholder(R.drawable.list_placeholder)
                .into(feedListRowHolder.thumbImage);


        feedListRowHolder.rssFeed = feedItem;
        feedListRowHolder.title.setText(feedItem.getTitle());
        feedListRowHolder.pubDate.setText(feedItem.getPubDate());
        feedListRowHolder.thumbImage.setImageResource((feedItem.getThumbImage()));
    }

    @Override
    public int getItemCount() {
        return (null != feedItemList ? feedItemList.size() : 0);
    }

    public class FeedListRowHolder extends RecyclerView.ViewHolder {

        protected TextView title;
        protected TextView pubDate;
        protected ImageView thumbImage;
        protected RSSFeed rssFeed;

        public FeedListRowHolder(View view) {
            super(view);

            this.title = (TextView) view.findViewById(R.id.tvtitle);
            this.pubDate = (TextView) view.findViewById(R.id.tvpubdate);
            this.thumbImage = (ImageView) view.findViewById(R.id.thumbImage);

            view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {


                    Intent webIntent = new Intent(v.getContext(), WebView.class);

                    webIntent.putExtra("title", rssFeed.getTitle().toString());

                    webIntent.putExtra("url", rssFeed.getLink().toString());

                    // String url=mRssFeedList.get(position).getLink().toString();

                    //   Log.i("onlcik Recycler",url);

                    v.getContext().startActivity(webIntent);
                }
            });
        }

    }

}
Kindly help

First off, I think it would be better to send the LogCat details too.

But I’d take a wild guess here.

This line of code:  feedListRowHolder.thumbImage.setImageResource((feedItem.getThumbImage())); isn’t required anymore since you’ve used Picasso to load the image. I’d assume that feedItem.getThumbImage() returns a String (presumably, the url for the image), but setImageResource expects an android resource (which is really an integer reference).

So, take out that line and it should work.

Like I said earlier, it’s a shot in the dark but one I feel a bit confident about.

Cheers.
