What things change in order to parse JSON Array

[mandy8055]

Sir I am learning Json parsing through Android. I just want to know what needs to be changed in the code in order to parse JSON array:The link is http://starlord.hackerearth.com/newsjson

My dear ! This is simple Json

You can delcare class

public class News{ public int ID { get; set; } public string TITLE { get; set; } public string URL { get; set; } public string PUBLISHER { get; set; } public string CATEGORY { get; set; } public string HOSTNAME { get; set; } public object TIMESTAMP { get; set; }}

And your Json just return array of News item :D ... you can convert it to News[]

Sorry Sir But I am a tyro in json parsing So I am not able to make changes accordingly in FeedAdapter and MainActivity class. Although I have created this class...(I apologize Sir for this silly issue but I am Still learning).I have changed accordingly Sir but here this error occurs:

holder.txtTitle.setText(news.get(position).getTITLE());
 return news.size();

It is indicating that size() and get() method cannot be used.I have changed the variable as News[] news. So Sir how do I set the news position to The recyclerView?

Show me your FeedAdapter

Sir here is the FeedViewHolder and FeedAdapter class.

class FeedViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener,View.OnLongClickListener
{

public TextView txtTitle,txtPubDate,txtContent;
private ItemClickListener itemClickListener;

public FeedViewHolder(View itemView) {
    super(itemView);

    txtTitle = (TextView)itemView.findViewById(R.id.txtTitle);
    txtPubDate = (TextView)itemView.findViewById(R.id.txtPubDate);
    txtContent = (TextView)itemView.findViewById(R.id.txtContent);

    //Set Event
    itemView.setOnClickListener(this);
    itemView.setOnLongClickListener(this);
}

public void setItemClickListener(ItemClickListener itemClickListener) {
    this.itemClickListener = itemClickListener;
}

@Override
public void onClick(View v) {

    itemClickListener.onClick(v,getAdapterPosition(),false);

}

@Override
public boolean onLongClick(View v) {
    itemClickListener.onClick(v,getAdapterPosition(),true);
    return true;
}
}

Here is the FeedAdapter class:

public class FeedAdapter extends RecyclerView.Adapter<FeedViewHolder> {

private Items[] rssObject;
//private List<Items> data = Collections.emptyList();
private Context mContext;
private LayoutInflater inflater;

public FeedAdapter(Items[] rssObject, Context mContext) {
    this.rssObject = rssObject;
    this.mContext = mContext;
    inflater = LayoutInflater.from(mContext);
}

@Override
public FeedViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
   View itemView = inflater.inflate(R.layout.row,parent,false);
    return new FeedViewHolder(itemView);
}

@Override
public void onBindViewHolder(FeedViewHolder holder, int position) {

    holder.txtTitle.setText(rssObject.get(position).getTITLE()); // ERROR HERE
    holder.txtPubDate.setText(rssObject.get(position).getPUBLISHER());//ERROR HERE
    holder.txtContent.setText(rssObject.get(position).getTIMESTAMP());//ERROR HERE

    holder.setItemClickListener(new ItemClickListener() {
        @Override
        public void onClick(View view, int position, boolean isLongClick) {
            if(!isLongClick)
            {
                Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(rssObject.get(position).getURL()));
                browserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                mContext.startActivity(browserIntent);
            }
        }
    });
}

@Override
public int getItemCount() {
    return rssObject.size();//ERROR HERE
}
}

[eddydn]

public class Items{ public int ID { get; set; } public string TITLE { get; set; } public string URL { get; set; } public string PUBLISHER { get; set; } public string CATEGORY { get; set; } public string HOSTNAME { get; set; } public object TIMESTAMP { get; set; }}

Declare your Item class like here

Show me code to create Adapter (at MainActivity)
