I'm trying to develop android application which can load images from the url in to RecyclerView With the help of Picasso library. But the problem comes that after some sequence "in my case after every 6 image" same image is duplicating in recyclerview. I'm added some code

@Override

public int getItemCount() {

    return data.length;

}



@Override

public long getItemId(int position) {

    return position;

}

in my adapter but this is not working for me.
Below is my currant adapter code please help me to findout the solution for this.

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {

    private Context context;

    private Img data;



    public MyAdapter(Context context, Img data) {

        this.context = context;

        this.data = data;

    }



    @Override

    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        LayoutInflater inflater = LayoutInflater.from(parent.getContext());

        View view = inflater.inflate(R.layout.image_row, parent, false);

        MyViewHolder holder = new MyViewHolder(view);

        return holder;

    }



    @Override

    public void onBindViewHolder(final MyViewHolder holder, int position) {

        final Img user = data[position];



        final String imageStr = user.getImgurl();

        String taKey = loadTaluka();

        final String id = user.getImgId().toString();



        if (user.getTaluka().equals(taKey)) {

            float date = Float.parseFloat(user.getDateTime());

            float lastDayDate = Float.parseFloat(dispDate()) - 1;

            if (date >= lastDayDate) {

                Picasso.with(holder.myImg.getContext()).load(imageStr).placeholder(R.drawable.loading_1).networkPolicy(NetworkPolicy.OFFLINE).into(holder.myImg, new Callback() {

                    @Override

                    public void onSuccess() {

                    }



                    @Override

                    public void onError() {

                        Picasso.with(holder.myImg.getContext()).load(imageStr).placeholder(R.drawable.loading_1).into(holder.myImg);

                    }

                });







            }

            holder.itemView.setOnClickListener(new View.OnClickListener() {

                @Override

                public void onClick(View v) {

                    Intent intent = new Intent(context, LoadImg.class);

                    intent.putExtra("url", imageStr);

                    intent.putExtra("id", id);

                    context.startActivity(intent);

                }

            });



        }



    }



    @Override

    public int getItemCount() {

        return data.length;

    }



    @Override

    public long getItemId(int position) {

        return position;

    }





/*

    @Override

    public int getItemViewType(int position) {

        return position;

    }*/

    public class MyViewHolder extends RecyclerView.ViewHolder {

        TextView userTitle;

        TextView age;

        TextView country;

        TextView url;

        public ImageView myImg;



        public MyViewHolder(View itemView) {

            super(itemView);

            myImg = (ImageView) itemView.findViewById(R.id.postImg);

        }

    }





    //Extras





    private String loadTaluka() {

        SharedPreferences sf = context.getSharedPreferences("Taluka", MODE_PRIVATE);

        return sf.getString("taluka", "a");

    }



    //Image Viewholder Adapter End

    private String dispDate() {

        Date c = Calendar.getInstance().getTime();



        @SuppressLint("SimpleDateFormat") SimpleDateFormat day = new SimpleDateFormat("dd");

        String dayFinal = day.format(c);



        @SuppressLint("SimpleDateFormat") SimpleDateFormat month = new SimpleDateFormat("MM");

        String monthFinal = month.format(c);



        @SuppressLint("SimpleDateFormat") SimpleDateFormat year = new SimpleDateFormat("yyyy");

        String yearFinal = year.format(c);



        @SuppressLint("SimpleDateFormat") SimpleDateFormat hour = new SimpleDateFormat("HH");

        String hourFinal = hour.format(c);



        String finalDate = Integer.toString(Integer.parseInt(dayFinal) + Integer.parseInt(monthFinal) + Integer.parseInt(yearFinal)) + "." + hourFinal;



        return finalDate;

    }





}



  -Thankyou.

Because of Recycler views RAM Management, the recycler view try to load cards from the cache and because of your recycler view's cache, the items loads incorrectly.
for preventing this you must add an else to your if like this:

if (date >= lastDayDate)

{

    //Do Your Code

}

else

{

    //The Default Item View Settings Here...

}
