Я пытаюсь разработать средство выбора даты, которое устанавливает значение представления текста, когда оно установлено.
Но я не могу выбрать телевизор из DialogFragment
который обрабатывает DialogFragment
даты.
Я попытался getView
но приложение зависает в определенной точке.
Вот мой код:
@SuppressLint("NewApi")
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
TextView mTextView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// R.layout.my_layout - that the layout where your textview is placed
View view = inflater.inflate(R.layout.activity_register_screen, container, false);
mTextView = (TextView) view.findViewById(R.id.tvDate);
// you can use your textview.
return view;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
int syear = year;
int smonth = month;
int sday = day;
// set selected date into textview
mTextView.setText(new StringBuilder().append(smonth + 1)
.append("-").append(sday).append("-").append(syear)
.append(" "));
}
}
Обновлен с новым кодом и следующей ошибкой:
