En mi aplicación, estoy usando el selector de fecha para establecer la fecha.Quiero establecer la fecha máxima del selector de fecha como la fecha de hoy de acuerdo con la fecha del sistema.No sé cómo establecer la fecha máxima del selector de fecha como la fecha de hoy. para resolver este problema.

La codificación de mi selector de fechas es:

private int pYear;
private int pMonth;
private int pDay;
static final int DATE_DIALOG_ID = 0;

final Calendar c = Calendar.getInstance();
pYear = c.get(Calendar.YEAR);
pMonth = c.get(Calendar.MONTH);
pDay = c.get(Calendar.DAY_OF_MONTH);

// Date picker
public Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:

        DatePickerDialog.OnDateSetListener pDateSetListener = new DatePickerDialog.OnDateSetListener() {

            public void onDateSet(DatePicker view, int year,
                    int monthOfYear, int dayOfMonth) {

                pYear = year;
                pMonth = monthOfYear;
                pDay = dayOfMonth;

                e_dob.setText(new StringBuilder()
                        // to set date in editext
                        .append(pDay).append("/").append(pMonth + 1)
                        .append("/").append(pYear).append(" "));
            }
        };
        return new DatePickerDialog(this, pDateSetListener, pYear, pMonth,
                pDay);

    }
    return null;
}

Utilice setMaxDate().

Por ejemplo, reemplace la return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay)declaración con algo como esto:

    DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
    dialog.getDatePicker().setMaxDate(new Date().getTime());
    return dialog;

Obtenga la fecha (y hora) de hoy y aplíquelas como fecha máxima.

Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Mounth -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());

TAMBIÉN PODEMOS HACER ESTO (verifique esta respuesta de Stackoverflow para System.currentTimeMillis () vs método Calendar)

long now = System.currentTimeMillis() - 1000;
dp_time.setMinDate(now);
dp_time.setMaxDate(now+(1000*60*60*24*7)); //After 7 Days from Now

Puede intentar reemplazar esta línea:

return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);

Por esos:

DatePickerDialog dpDialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
DatePicker datePicker = dpDialog.getDatePicker();

Calendar calendar = Calendar.getInstance();//get the current day
datePicker.setMaxDate(calendar.getTimeInMillis());//set the current day as the max date
return dpDialog;

Prueba esto

He probado demasiadas soluciones pero ninguna de ellas funcionaba. Después de perder mi medio día, finalmente hice una solución.

Este código simplemente le muestra un DatePickerDialog con fecha mínima y máxima, mes y año, lo que quiera, simplemente modifíquelo.

final Calendar calendar = Calendar.getInstance();
                DatePickerDialog dialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker arg0, int year, int month, int day_of_month) {
                        calendar.set(Calendar.YEAR, year);
                        calendar.set(Calendar.MONTH, (month+1));
                        calendar.set(Calendar.DAY_OF_MONTH, day_of_month);
                        String myFormat = "dd/MM/yyyy";
                        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());
                        your_edittext.setText(sdf.format(calendar.getTime()));
                    }
                },calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
                dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());// TODO: used to hide previous date,month and year
                calendar.add(Calendar.YEAR, 0);
                dialog.getDatePicker().setMaxDate(calendar.getTimeInMillis());// TODO: used to hide future date,month and year
                dialog.show();

Salida: - Deshabilitar calendario anterior y futuro

private int pYear;
private int pMonth;
private int pDay;
static final int DATE_DIALOG_ID = 0;

/**inside oncreate */
final Calendar c = Calendar.getInstance();
         pYear= c.get(Calendar.YEAR);
         pMonth = c.get(Calendar.MONTH);
         pDay = c.get(Calendar.DAY_OF_MONTH);


 @Override
     protected Dialog onCreateDialog(int id) {
             switch (id) {
             case DATE_DIALOG_ID:
                     return new DatePickerDialog(this,
                             mDateSetListener,
                             pYear, pMonth-1, pDay);
            }

             return null;
     }
     protected void onPrepareDialog(int id, Dialog dialog) {
             switch (id) {
             case DATE_DIALOG_ID:
                     ((DatePickerDialog) dialog).updateDate(pYear, pMonth-1, pDay);
                     break;
             }
     }   
     private DatePickerDialog.OnDateSetListener mDateSetListener =
         new DatePickerDialog.OnDateSetListener() {
         public void onDateSet(DatePicker view, int year, int monthOfYear,
                         int dayOfMonth) {
                // write your code here to get the selected Date
         }
 };

prueba esto debería funcionar. Gracias

use este código directamente en el método principal espero que le ayude ...

    pickerDialog.getDatePicker().setMaxDate(Calendar.getInstance().getTimeInMillis());

    pickerDialog.show();

    return null;

Aquí hay una función de extensión de Kotlin:

    val myCalendar = Calendar.getInstance()

            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)

            val sdf = SimpleDateFormat(format, Locale.UK)
            setText(sdf.format(myCalendar.time))
        }

    setOnClickListener {
        DatePickerDialog(
            context, datePickerOnDataSetListener, myCalendar

            myCalendar.get(Calendar.DAY_OF_MONTH)

            maxDate?.time?.also { datePicker.maxDate = it }
            show()
        }
    }
}

Uso:

En actividad:

editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())

En Fragmentos:

editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())

Puede crear un selector de fecha personalizado , que funciona para todos los niveles de API.

establecer fecha máxima

Resolví esto siguiendo

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);
    datePickerDialog = new DatePickerDialog(getActivity(), this, year, month, day);
    datePickerDialog.getDatePicker().setMinDate(c.getTimeInMillis());    

Espero que te ayude

DatePicker dp = (DatePicker) findViewById(R.id.datePicker1);

dp.setMaxDate(new Date().getTime());
