studio - Android: use un marcador de fecha y un marcador de tiempo desde dentro de un cuadro de diálogo

personalizar datepicker android studio

Question

Me enfrenta a un problema que no sé cómo resolver ... Tengo una actividad, cuando hago clic en un elemento en particular del menú vinculado a esta actividad, se muestra un cuadro de diálogo y se usa para agregar un elemento. Este artículo tiene una fecha y una hora, pero no logro tener un DatePicker y TimePicker dentro de este cuadro de diálogo. También intento pasar la actividad al cuadro de diálogo y usar esta para mostrar el marcador de fecha, pero eso no funciona. Antes de esto, manejé la creación de tales artículos dentro de otra actividad. En este caso, funciona bien. Pero encontré el Dialog más sexy ... :-) ¿Tendría alguna idea? Espero no estar demasiado confundido ... muchas gracias, Luc

Edito esta publicación para compartir el código con el que tengo dificultades.

Tengo una clase básica de Diálogo que intentó usar DatePicker y TimePicker. Básicamente, Eclipse se queja de que:

• el showDialog no está definido para View.OnClickListener ()
• método onCreateDialog: el método onCreateDialog (int) de tipo EventCreateDialog debe anular o implementar un método de supertipo
• DatePickerDialog no está definido (ya que no es una actividad)

Todo esto funciona desde dentro de una actividad, pero no puedo hacerlo funcionar desde un cuadro de diálogo.

Muchas gracias, Luc

Answer 1

Esto debería funcionar:

mPickDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { context.showDialog(DATE_DIALOG_ID); }
});

onCreateDialog solo se puede llamar desde dentro de una actividad

Answer 2

Esto es lo que tengo que funciona:

public class EditRecordDialog extends Dialog {
protected Context _context;
private Record _record;
public EditRecordDialog( Context context,
Record record ) {
super( context );
_context = context;
_record = record
Button buttonDate;
buttonDate.setText( _record.getRecordDate() ); // returns ''mm-dd-yy''
} // EditRecordDialog
// showDatePickerDialog ++++++++++++++++++++++++++++++++++++++++++++++++++++++
private void showDatePickerDialog( View view ) {
String dateString;
int year, month, day;
dateString = buttonDate.getText().toString();
month = Integer.valueOf( dateString.substring( 0, 2 ) ) - 1; // month is zero based
day = Integer.valueOf( dateString.substring( 3, 5 ) );
year = Integer.valueOf( "20" + dateString.substring( 6, 8 ) );
DatePickerDialog dpd = new DatePickerDialog( _context, dateSetListener, year, month, day );
dpd.show();
} // showDatePickerDialog ----------------------------------------------------
// OnDateSetListener +++++++++++++++++++++++++++++++++++++++++++++++++++++++++
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {
@Override public void onDateSet( DatePicker view, int year, int month, int day ) {
buttonDate.setText( ConfigObjectDAO.formatDate( (month+1) + "-" + day + "-" + year ) );
} // onDateSet
}; // OnDateSetListener ------------------------------------------------------
}

Answer 4

declarar variables en global como:

private int year, month, day, Hour, Minute;
public static final int DATE_PICKER_ID = 1111;

en onCreate ()

// Get current date by calender
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);

llamar a datepicker desde el botón clic

showDialog(Constant.DATE_PICKER_ID);

métodos:

 @Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case Constant.DATE_PICKER_ID:
// open datepicker dialog.
// set date picker for current date
// add pickerListener listner to date picker
return new DatePickerDialog(this, pickerListener, year, month, day);
case Constant.TIME_PICKER_ID:
return new TimePickerDialog(this, timeSetListener, Hour, Minute, false);
}
return null;
}
private DatePickerDialog.OnDateSetListener pickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
@Override
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
year = selectedYear;
month = selectedMonth;
day = selectedDay;
text_date.setText(new StringBuilder().append(month + 1)
.append("/").append(day).append("/").append(year)
.append(" "));
}
};
