Add OnClickListner to CardView and get data

I wan to attach an OnClickListener to a CardView, so i can get the ID from the card

I have a RecyclerView that has a custom adapter for displaying the cards. This is how it's implemented.

I tried other examples in stackoverflow but it didn't work .

public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder> {
private ArrayList<Patient> patients;
Context mContext;
String idPatient;

public CardAdapter(ArrayList<Patient> patients) {
    this.patients = patients;
    }

        @Override
public CardAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_card_view, viewGroup, false);
    return new ViewHolder(view);
    }

@Override
 public void onBindViewHolder(CardAdapter.ViewHolder viewHolder, int i) {

    viewHolder.first_name.setText(patients.get(i).getFirstName());
    viewHolder.last_name.setText(patients.get(i).getLastName());
    viewHolder.id_patient.setText(String.valueOf(patients.get(i).getId()));

    viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //trying to get ID From card
            ViewGroup parentView = (ViewGroup)v.getParent();
            TextView idpatientview =(TextView)parentView.findViewById(R.id.idViewPatient);
            idPatient = idpatientview.getText().toString();
            PreferencesHelper.save(mContext, "idPatient", idPatient);
            Intent intent = new Intent(mContext, BluetoothActivity.class);
             mContext.startActivity(intent);

        }
    });

    }

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

public class ViewHolder extends RecyclerView.ViewHolder{
            private TextView first_name,last_name,id_patient;
   public ViewHolder(View view) {
        super(view);

        first_name = (TextView)view.findViewById(R.id.textViewName);
        last_name = (TextView)view.findViewById(R.id.textViewLastName);
        id_patient = (TextView)view.findViewById(R.id.idViewPatient);

   }
        }
               }

If your onClick method is inside your onBindViewHolder, then you can get the current data directly

String first_name = patients.get(i).getFirstName();
String last_name = patients.get(i).getLastName();
String id_patient = String.valueOf(patients.get(i).getId());

in your onClickListener, the id of the patient corresponding to the clicked card is simply id_patient, the first name is first_name and the last name is last_name. You can now pass the data to your activity (with an interface for exemple)
