Answer 1

You can use below code for getting contact list in Recyclerview;

  List contactVOList = new ArrayList();

  String[] projection = new String[]{ContactsContract.Contacts._ID, ContactsContract.Data.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.PHOTO_URI};
    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, null, null,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    List userList = new ArrayList<>();

    String lastPhoneName = " ";
    if (phones.getCount() > 0) {
        while (phones.moveToNext()) {
            String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            String contactId = phones.getString(phones.getColumnIndex(ContactsContract.Contacts._ID));
            String photoUri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
            if (!name.equalsIgnoreCase(lastPhoneName)) {
                lastPhoneName = name;
                ContactVO user = new ContactVO();
                user.setContactName(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
                user.setContactNumber(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
                userList.add(user);
                Log.d("getContactsList", name + "---" + phoneNumber + " -- " + contactId + " -- " + photoUri);
            }
        }
    }
    phones.close();

    AllContactsAdapter contactAdapter = new AllContactsAdapter(userList, getApplicationContext());
    rvContacts.setLayoutManager(new LinearLayoutManager(PhoneDirectoryActivity.this));
    rvContacts.setAdapter(contactAdapter);

Below ContactVO class file;

public class ContactVO
{
private String ContactImage;
private String ContactName;
private String ContactNumber;

public String getContactImage() {
    return ContactImage;
}

public void setContactImage(String contactImage) {
    this.ContactImage = ContactImage;
}

public String getContactName() {
    return ContactName;
}

public void setContactName(String contactName) {
    ContactName = contactName;
}

public String getContactNumber() {
    return ContactNumber;
}

public void setContactNumber(String contactNumber) {
    ContactNumber = contactNumber;
}
}

and below is AllContactsAdapter file

    public class AllContactsAdapter extends RecyclerView.Adapter {

    private List contactVOList;
    private Context mContext;
    private SparseBooleanArray itemStateArray = new SparseBooleanArray();

    public AllContactsAdapter(List contactVOList, Context mContext) {
        this.contactVOList = contactVOList;
        this.mContext = mContext;
    }

    @Override
    public ContactViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.single_contact_view, null);
        ContactViewHolder contactViewHolder = new ContactViewHolder(view);
        return contactViewHolder;
    }

    @Override
    public void onBindViewHolder(ContactViewHolder holder, int position) {
        ContactVO contactVO = contactVOList.get(position);
        holder.tvContactName.setText(contactVO.getContactName());
        holder.tvPhoneNumber.setText(contactVO.getContactNumber());

        holder.bind(position);

        holder.cbContact.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int adapterPosition = position;
                if (!itemStateArray.get(adapterPosition, false)) {
                    holder.cbContact.setChecked(true);
                    contactsList.add(holder.tvPhoneNumber.getText().toString());
                    itemStateArray.put(adapterPosition, true);
                } else {
                    holder.cbContact.setChecked(false);
                    itemStateArray.put(adapterPosition, false);
                    contactsList.remove(holder.tvPhoneNumber.getText().toString());
                }
            }
        });
    }

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

    public class ContactViewHolder extends RecyclerView.ViewHolder {

        ImageView ivContactImage;
        TextView tvContactName;
        TextView tvPhoneNumber;
        CheckBox cbContact;

        public ContactViewHolder(View itemView) {
            super(itemView);
            ivContactImage = itemView.findViewById(R.id.ivContactImage);
            tvContactName = itemView.findViewById(R.id.tvContactName);
            tvPhoneNumber = itemView.findViewById(R.id.tvPhoneNumber);
            cbContact = itemView.findViewById(R.id.cbContact);
        }
        void bind(int arg1) {
            // use the sparse boolean array to check
            if (!itemStateArray.get(arg1, false)) {
                cbContact.setChecked(false);
            } else {
                cbContact.setChecked(true);
            }
        }
    }
}
