RecyclerView, android sunucudan görüntüleri yüklerken sorunsuz kaydırma yapmıyor

Question

Android Material Design için yeni ve bir RecyclerView uygulamaya çalışıyorum. Ben sunucudan veri yükleme (görüntüleri içerir). Imageview Image yüklemek için ION kütüphane kullanıyorum. Kontrol ettiğim bir koşula bağlı olarak birkaç görüntüyü şişirmem gerekiyor. Şu anda farklı koşullar için aynı görünümü şişiriyorum. Verilerin görüntüleri ve geri kalanı doğru şekilde yüklendi, ancak geri bildirim görüntüsünü kaydırdığımda düzgün değil ve sarsıntılı bir his veriyor. Kayan pürüzsüz ve nasıl yanlış gittiğimi nasıl anlatabilirim. aşağıdaki gibi Benim kodlardır:

NewsFeedAdapter

public class NewsFeedAdapter extends RecyclerView.Adapter<NewsFeedAdapter.ParentViewHolder> { 
ArrayList<OneFragmentData> arr_data; 
Context context; 
public static int height; 
public static int IMAGE_POLL = 1; 

LinearLayoutManager linearLayoutManager; 
ArrayList<OptiondData> arr_suboptions = new ArrayList<OptiondData>(); 
ArrayList<OptiondData> arr_options = new ArrayList<OptiondData>(); 
ArrayList<QuestionsData> arr_suboptions_answers = new ArrayList<QuestionsData>(); 
RecyclerView recyclerview; 
Activity activity; 

public NewsFeedAdapter(ArrayList<OneFragmentData> arr_data, Context context, LinearLayoutManager linearLayoutManager, RecyclerView recyclerview, Activity activity) { 
    this.arr_data = arr_data; 
    this.context = context; 
    this.linearLayoutManager = linearLayoutManager; 
    this.recyclerview = recyclerview; 
    this.activity = activity; 


} 

@Override 
public int getItemViewType(int position) { 
    if ((arr_data.get(position).getPoll_type().compareToIgnoreCase("ques_poll") == 0) && (arr_data.get(position).getItem_type().compareToIgnoreCase("poll") == 0)) { 
     return IMAGE_POLL;//poll with image and text options 
    } else if ((arr_data.get(position).getPoll_type().compareToIgnoreCase("img_poll") == 0) && (arr_data.get(position).getItem_type().compareToIgnoreCase("poll") == 0)) { 
     return IMAGE_POLL; 
    } else { 
     return IMAGE_POLL; 
    } 
    //return super.getItemViewType(position); 
} 

@Override 
public ParentViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view; 
    if (viewType == IMAGE_POLL) { 
     view = LayoutInflater.from(parent.getContext()).inflate(R.layout.poll_new_card, parent, false); 

     return new PollHolder(view); 
    } else { 
     view = LayoutInflater.from(parent.getContext()).inflate(R.layout.poll_new_card, parent, false); 
     return new PollHolder(view); 
    } 

} 

@Override

    if (holder.getItemViewType() == IMAGE_POLL) { 
     PollHolder pollHolder = (PollHolder) holder; 
     pollHolder.tv_posted_date_pic_pol3_new_poll.setText(arr_data.get(position).getParticipation());

yük bu görüntü sonrası gradle file.than içinde picasa kütüphanesini eklemek sınıf (Fragman uzanır)

Picasso.with(context).load(itm.getImage()).into(imageView); 

da bu problemi görüntü yükü meydana olduğu görüntü loading.because için
