In meiner Anwendung verwende ich die Datumsauswahl, um das Datum festzulegen. Ich möchte das maximale Datum der Datumsauswahl als das heutige Datum gemäß dem Systemdatum festlegen. Ich weiß nicht, wie ich das maximale Datum der Datumsauswahl als das heutige Datum festlegen kann. Kann mir jemand helfen? um dieses Problem zu lösen.

Meine Datumsauswahl-Codierung lautet:

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;
}

Verwenden Sie setMaxDate().

Ersetzen Sie beispielsweise die return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay)Anweisung durch Folgendes:

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

Holen Sie sich das heutige Datum (und die heutige Uhrzeit) und wenden Sie sie als maximales Datum an.

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

AUCH WIR KÖNNEN DAS TUN (überprüfen Sie diese Stackoverflow-Antwort auf System.currentTimeMillis () vs Calendar-Methode)

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

Sie können versuchen, diese Zeile zu ersetzen:

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

Von denen:

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;

Versuche dies

Ich habe zu viele Lösungen ausprobiert, aber keine funktionierte. Nachdem ich meinen halben Tag verschwendet hatte, machte ich endlich eine Lösung.

Dieser Code zeigt Ihnen einfach einen DatePickerDialog mit minimalem und maximalem Datum, Monat und Jahr, was auch immer Sie möchten, ändern Sie es einfach.

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();

Ausgabe: - Deaktivieren Sie den vorherigen und zukünftigen Kalender

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
         }
 };

Versuchen Sie dies, es sollte funktionieren. Vielen Dank

Verwenden Sie diesen Code direkt in der Hauptmethode. Ich hoffe, er hilft Ihnen ...

@RequiresApi(api = Build.VERSION_CODES.N)       
public DatePickerDialog datePickerDialog_db()
{

    DatePickerDialog pickerDialog = new DatePickerDialog(getApplicationContext(),your view, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
    myCalendar.get(Calendar.DAY_OF_MONTH));

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

    pickerDialog.show();

    return null;       
}

Verwendung

Kopieren Sie EightFoldsDatePickerDialog.java in Ihr Projekt

EightFoldsDatePickerDialog datePickerDialog=new EightFoldsDatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
              //Do something with date
                Toast.makeText(this, "Year "+year+" month "+month+" day "+dayOfMonth, Toast.LENGTH_SHORT).show();
            }
        },year,month,day);   // give any  year , month , day values, this will be opened by default in dialog

        datePickerDialog.setMinDate(2017,8,7); //arguments are   year , month , date (use for setting custom min date)
        datePickerDialog.setMaxDate(2017,8,25);  //arguments are   year , month , date (use for setting custom max date)

       // datePickerDialog.setTodayAsMinDate();   // sets today's date as min date
       // datePickerDialog.setTodayAsMaxDate();    // sets today's date as max date

        datePickerDialog.show();

Ergebnis

Hier ist eine Kotlin-Erweiterungsfunktion:

fun EditText.transformIntoDatePicker(context: Context, format: String, maxDate: Date? = null) {
    isFocusableInTouchMode = false
    isClickable = true
    isFocusable = false

    val myCalendar = Calendar.getInstance()
    val datePickerOnDataSetListener =
        DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
            val sdf = SimpleDateFormat(format, Locale.UK)
            setText(sdf.format(myCalendar.time))
        }

    setOnClickListener {
        DatePickerDialog(
            context, datePickerOnDataSetListener, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
            myCalendar.get(Calendar.DAY_OF_MONTH)
        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
        }
    }
}

Verwendung:

In Aktivität:

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

In Fragmenten:

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

Sie können eine benutzerdefinierte Datumsauswahl erstellen , die für alle API-Ebenen funktioniert.

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);
        }
    }

Maximales Datum einstellen

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

Ich löste dies, indem ich folgte

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());
