Populating a TextView with a Boolean Value retrieved using a getter method

Question

I have developed an Android Application which is connected to a Firebase Database. I'm trying to display some records from a database object in a ListView but I'm not sure how to hand the boolean value. I currently have a GroupVaccinations class which has the Getters for all the info:

public class GroupVaccination {
    String vaccinationGroupID;
    String vaccinationGroupNumber;
    String vaccinationID;
    String vaccinationDrug;
    String vaccinationAdmin;
    String vaccinationDosage;
    String vaccinationDate;
    String vaccinationNotes;
    Boolean allVaccinated;

    public GroupVaccination(){

    }

    public GroupVaccination(String vaccinationGroupID, String vaccinationGroupNumber, String vaccinationID, String vaccinationDrug,
                       String vaccinationAdmin, String vaccinationDosage, String vaccinationDate, String vaccinationNotes, Boolean allVaccinated){
        this.vaccinationGroupID = vaccinationGroupID;
        this.vaccinationGroupNumber = vaccinationGroupNumber;
        this.vaccinationID = vaccinationID;
        this.vaccinationDrug = vaccinationDrug;
        this.vaccinationAdmin = vaccinationAdmin;
        this.vaccinationDosage = vaccinationDosage;
        this.vaccinationDate = vaccinationDate;
        this.vaccinationNotes = vaccinationNotes;
        this.allVaccinated = allVaccinated;
    }

    public String getVaccinationGroupID() {   return vaccinationGroupID;    }

    public String getVaccinationGroupNumber() {   return vaccinationGroupNumber;    }

    public String getVaccinationID() {  return vaccinationID;    }

    public String getVaccinationDrug() { return vaccinationDrug; }

    public String getVaccinationAdmin() { return  vaccinationAdmin;}

    public String getVaccinationDosage() {return vaccinationDosage;}

    public String getVaccinationDate() {return  vaccinationDate; }

    public String getVaccinationNotes() {return vaccinationNotes; }

    public Boolean getAllVaccinated() {return allVaccinated; }

And I am using an InfoAdapter class to populate the ListView accordingly:

public class GroupVaccinationInfoAdapter extends ArrayAdapter<GroupVaccination> {
    private Activity context;
    private List<GroupVaccination> groupVaccinationList;

public GroupVaccinationInfoAdapter(Activity context, List<GroupVaccination>groupVaccinationList){
    super(context, R.layout.group_vaccination_list_view,groupVaccinationList);
    this.context = context;
    this.groupVaccinationList = groupVaccinationList;
}

@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    LayoutInflater inflater = context.getLayoutInflater();
    View listView = inflater.inflate(R.layout.group_vaccination_list_view, null, true);

    TextView vaccinationDrug = (TextView)listView.findViewById(R.id.drug);
    TextView vaccinationDosage = (TextView)listView.findViewById(R.id.dosage);
    TextView vaccinationDate = (TextView)listView.findViewById(R.id.date);
    TextView vaccinationAdmin = (TextView)listView.findViewById(R.id.administrator);
    TextView vaccinationID = (TextView) listView.findViewById(R.id.groupVaccinationID);
    TextView vaccinationGroupNumber = (TextView)listView.findViewById(R.id.groupNumber);
    TextView vaccinationNotes = (TextView)listView.findViewById(R.id.notes);
    TextView allVaccinatedTrueFalse = (TextView)listView.findViewById(R.id.allVaccinatedTrueFalse);



    GroupVaccination groupVaccination = groupVaccinationList.get(position);
    vaccinationDrug.setText(groupVaccination.getVaccinationDrug());
    vaccinationDosage.setText(groupVaccination.getVaccinationDosage());
    vaccinationDate.setText(groupVaccination.getVaccinationDate());
    vaccinationID.setText(groupVaccination.getVaccinationID());
    vaccinationAdmin.setText(groupVaccination.getVaccinationAdmin());
    vaccinationGroupNumber.setText(groupVaccination.getVaccinationGroupNumber());
    vaccinationNotes.setText(groupVaccination.getVaccinationNotes());
allVaccinatedTrueFalse.setText(String.valueOf(Boolean groupVaccination.getAllVaccinated));

    return listView;
}

I have an error when I try to convert the Boolean to a String for allVaccinatedTrueFalse.setText. I'm assuming this way is wrong so any help would be appreciated! Let me know if there is any additonal information needed. Thank you!

To solve this, please change the following line of code:

allVaccinatedTrueFalse.setText(String.valueOf(Boolean groupVaccination.getAllVaccinated));

to

allVaccinatedTrueFalse.setText(String.valueOf(groupVaccination.getAllVaccinated()));
