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

Question

Tengo 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 diálogo y se usa para agregar un artículo. 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 dichos artículos dentro de otra actividad. En este caso, funciona bien. Pero encontré el Diálogo más sexy ... :-) ¿Alguna idea? Hope No estoy demasiado confundido ..... Muchas gracias, Luc

edito este post para compartir el código que tengo problemas con.

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

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

Todo esto funciona desde dentro de una actividad pero no puedo tenerlo funcionando 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 sólo puede ser llamado desde dentro de una actividad

Answer 3

Aquí 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 onCrea Te()

// 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); 

llamada selector de fechas del botón de 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(" ")); 


    } 
};
