get the time and minutes of a TimePickerDialog on frgaments android

Does anyone know how to get the Time and the minute of a TimePickerDialog? I have two buttons in a fragment, one that triggers a DataPickerDialog from which I get the date very well and a button that launches a TimePickerDialog but gives me an error when accepting once the selected time has been selected. How can I get the value and show it to me in a textview.

Here is my code:

public class AgendaFragment extends Fragment   {

public AgendaFragment() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    ((MainActivity) getActivity()).setActionbarTitle("Horario");
    View view = inflater.inflate(R.layout.fragment_agenda, container, false);



    Button btime = (Button) view.findViewById(R.id.btntime);
    Button bdate = (Button) view.findViewById(R.id.btndate);
    Button bsen = (Button) view.findViewById(R.id.btnsend);

    final TextView datvi = (TextView) view.findViewById(R.id.viewdate);
    final TextView tievi = (TextView) view.findViewById(R.id.viewti);
    final Calendar c = Calendar.getInstance();
    final int hora = c.get(Calendar.HOUR_OF_DAY);
    final int minuto = c.get(Calendar.MINUTE);


    bdate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            final Calendar calendario = Calendar.getInstance();
            int yy = calendario.get(Calendar.YEAR);
            int mm = calendario.get(Calendar.MONTH);
            int dd = calendario.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog datePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    String fecha = String.valueOf(year) + "-" + String.valueOf(monthOfYear)
                            + "-" + String.valueOf(dayOfMonth);
                    datvi.setText(fecha);
                }
            }, yy, mm, dd);
            datePicker.show();
        }
    });


    btime.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            final Calendar getDate = Calendar.getInstance();
            TimePickerDialog timePickerDialog = new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    getDate.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    getDate.set(Calendar.MINUTE, minute);
                    SimpleDateFormat timeformat=new SimpleDateFormat("HH:mm a");
                    timeformat.format(getDate.getTime());
                    tievi.setText((CharSequence) timeformat);
                }
            }, getDate.get(Calendar.HOUR_OF_DAY), getDate.get(Calendar.MINUTE), false);

            timePickerDialog.show();
        }
    });

    return view;

}
