RecyclerView items duplicate and constantly changing

Question

What's Happening:

The list (RecyclerView) is mixing up the data when I scroll.

I.E when I scroll back up after scrolling down, some of the list items are repeated, not displaying proper content.

package jamesnguyen.newzyv2.UI_update;  import android.content.Context; import android.support.v7.widget.CardView; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView;  import java.util.List;  import jamesnguyen.newzyv2.R; import jamesnguyen.newzyv2.RSS_Processcors.RssItem;  public class RVAdapter extends RecyclerView.Adapter<RVAdapter.FeedViewHolder> {      private static List<RssItem> items = null;     private static Context context;      public RVAdapter(Context context, List<RssItem> items) {         this.items = items;         this.context = context;     }      public static List<RssItem> getItems() {         return items;     }      @Override     public RVAdapter.FeedViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {         View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item, viewGroup, false);         return new FeedViewHolder(v);     }      @Override     public void onBindViewHolder(RVAdapter.FeedViewHolder holder, int position) {         FeedViewHolder.getTitle().setText(items.get(position).getTitle());         FeedViewHolder.getPubDate().setText(items.get(position).getPubDate());         //FeedViewHolder.getDescription().setText(items.get(position).getDescription());     }      @Override     public long getItemId(int id) {         return id;     }      @Override     public int getItemCount() {         return items.size();     }      @Override     public void onAttachedToRecyclerView(RecyclerView recyclerView) {         super.onAttachedToRecyclerView(recyclerView);     }      public static class FeedViewHolder extends RecyclerView.ViewHolder {         private static CardView cv;         private static TextView title;         private static TextView pubDate;         private static TextView description;          FeedViewHolder(View itemView) {             super(itemView);             cv = (CardView) itemView.findViewById(R.id.cv);             title = (TextView) itemView.findViewById(R.id.title);             pubDate = (TextView) itemView.findViewById(R.id.pubDate);             //description = (TextView) itemView.findViewById(R.id.description);         }          public static TextView getTitle() {             return title;         }          public static TextView getPubDate() {             return pubDate;         }          public static TextView getDescription() {             return description;         }     } } 

I believe maybe some works have to be done with the recycling process of RecyclerView but nothing i tried seesm to work.

Answer 1

done .

@Override public long getItemId(int position) {     return position; }  @Override public int getItemViewType(int position) {    return position; } 

Answer 2

Only two things in your RecyclerView adapter

 @Override public long getItemId(int position) {     return position; } 

and in constructor of adapter

 setHasStableIds(true); 

Hope it helps!
