    }
});

private void detailPeople(int position) {
    Intent intent = new Intent(this, AddDetail.class);
    intent.putExtra("peopleID", position);
    startActivity(intent);
}

Model.class

public class People implements Serializable {
    private String peopleImage;
    private String peopleName;
    private String id;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public void setPeopleName(String peopleName) {
        this.peopleName = peopleName;
    }

    public String getPeopleName() {
        return peopleName;
    }

    public void setPeopleImage(String peopleImage) {
        this.peopleImage = peopleImage;
    }

    public String getPeopleImage() {
        return peopleImage;
    }
}

Adapter code

public class BuildCustomAdapter extends RecyclerView.Adapter<BuildCustomAdapter.MyViewHolder> implements Filterable {
private List<People> peopleList;
private List<People> peopleListCopy;
private ItemFilter mFilter = new ItemFilter();
private OnItemClickListener mOnItemClickListener;
private Context mContext;

public BuildCustomAdapter(Context context, List<People> buildList) {
    mContext = context;
    this.peopleList = buildList;
    this.peopleListCopy = new ArrayList<>();
    peopleListCopy.addAll(buildList);
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.build_list_row, parent, false);

    return new MyViewHolder(itemView);
}


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

    People people = peopleList.get(position);

    byte[] decodedString = Base64.decode(people.getPeopleImage(), Base64.DEFAULT);
    Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
    holder.ivPeopleImage.setImageBitmap(decodedByte);
    holder.tvPersonName.setText(people.getPeopleName());

    holder.button.setSelected(people.getStatus() == 1);
    holder.button.setOnClickListener(new onSelectListener(position));

}

@Override
public int getItemCount() {
    return peopleList.size();
}

@Override
public Filter getFilter() {
    if (mFilter == null) {
        mFilter = new ItemFilter();
    }
    return mFilter;
}

public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    public TextView tvPersonName;
    public Button button;
    public CircularImageView ivPeopleImage;


    public MyViewHolder(View itemView) {
        super(itemView);
        mContext = itemView.getContext();
        ivPeopleImage = (CircularImageView) itemView.findViewById(R.id.ivPerson);
        tvPersonName = (TextView) itemView.findViewById(R.id.tvPersonName);
        button = (Button) itemView.findViewById(R.id.addbn);
        tvPersonName.setOnClickListener(this);
        ivPeopleImage.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (mOnItemClickListener != null)
            mOnItemClickListener.onItemClick(v, getPosition());
    }
}

public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
    mOnItemClickListener = onItemClickListener;
}

public interface OnItemClickListener {
    void onItemClick(View view, int position);

}

private class ItemFilter extends Filter {

    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        if (constraint != null && constraint.length() > 0) {
            List<People> filterList = new ArrayList<>();

            for (int i = 0; i < peopleListCopy.size(); i++) {
                if ((peopleListCopy.get(i).getPeopleName().toUpperCase())
                        .contains(constraint.toString().toUpperCase())) {

                    People peopleName = peopleListCopy.get(i);
                    filterList.add(peopleName);
                }
            }
            results.count = filterList.size();
            results.values = filterList;

        } else {
            results.count = peopleListCopy.size();
            results.values = peopleListCopy;
        }
        return results;
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        peopleList = (List<People>) results.values;
        notifyDataSetChanged();
    }
}


private class onSelectListener implements View.OnClickListener {

    int mPosition;

    public onSelectListener(int position) {
        mPosition = position;
    }

    @Override
    public void onClick(View view) {
        People people = peopleList.get(mPosition);
        view.setSelected(!view.isSelected());
        people.setStatus(view.isSelected() ? 1 : 0);
        notifyDataSetChanged();
    }
}

} Next Activity to get intent

   Bundle bundle = getIntent().getExtras();
    if (bundle != null) {
        int peopleID = bundle.getInt("peopleID");
        peopleList.clear();

        BuildDataa();
        People peopleDetailsObj = peopleList.get(peopleID);
}

From where do you get the data for displaying in a ListView? — vidulaJ, Oct 25 '16 at 06:18
use getTag() for recycleView, instead of getId()/getPosition() — Emdad Hossain, Oct 25 '16 at 06:19

Please replace

@Override
public void onClick(View v) {
    if (mOnItemClickListener != null)
        mOnItemClickListener.onItemClick(v, getPosition());
}

to

    @Override
public void onClick(View v) {
    if (mOnItemClickListener != null)
        mOnItemClickListener.onItemClick(v, peopleList.get(getPosition()).getId());
}

in your adapter. And change signature of method onItemClick from

onItemClick(View v, int position)

to

onItemClick(View v, String id)

and use this to get People according to ID

  People peopleDetailsObj=null;
  for(People ple:peopleList)
  {
    if(ple.getId().equals(peopleID)){
  peopleDetailsObj=ple;
     break;
   }}

Take the id from position.

String id=peopleList.get(position).getId();
detailPeople(id);

Pass that id in your method and you are done.

Add the clicklistner inside the adapter. Make root layout id then on that layout id put click listner inside bindview. It will work...you can try....I use like this...only...!!! – Avinash Verma Oct 25 '16 at 06:40

Use position to get People object from ArrayList. Change detailPeople() method with below code.

private void detailPeople(int position) {

Intent intent = new Intent(this, AddDetail.class);
intent.putExtra("peopleID", peopleList.get(position).getId());
startActivity(intent);
}
