Come impostare la data massima nella finestra di dialogo datepicker in Android?



Answers

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

ANCHE POSSIAMO FARE QUESTO

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

Nella mia applicazione sto usando la selezione della data per impostare la data. Voglio impostare la data massima del selettore della data è come data odierna in base alla data del sistema. Non so come impostare la data massima di selezione data come data di oggi. Qualcuno sa aiutarmi risolvere questo problema.

Il mio codice di selezione data è:

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;
}



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

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



È possibile creare un gist.github.com/Kishanjvaghela/7b8738bbb224c5f2e652 , ovvero funziona per tutti i livelli API.

public class CustomDatePickerDialog extends DatePickerDialog {

    int maxYear;
    int maxMonth;
    int maxDay;

    public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
        super(context, callBack, year, monthOfYear, dayOfMonth);
    }

    public void setMaxDate(long maxDate) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            getDatePicker().setMaxDate(System.currentTimeMillis());
        } else {
            final Calendar c = Calendar.getInstance();
            c.setTimeInMillis(maxDate);
            maxYear = c.get(Calendar.YEAR);
            maxMonth = c.get(Calendar.MONTH);
            maxDay = c.get(Calendar.DAY_OF_MONTH);
        }
    }

    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            super.onDateChanged(view, year, monthOfYear, dayOfMonth);
        } else {
            if (year > maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

            if (monthOfYear > maxMonth && year == maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

            if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
                view.updateDate(maxYear, maxMonth, maxDay);
        }
    }

imposta la data massima

final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(getActivity(),
        myDateListener, year, month, day);
pickerDialog.setMaxDate(System.currentTimeMillis());
pickerDialog.show();

prova questo dovrebbe funzionare. Grazie
