在我的应用程序中使用日期选择器来设置date.i想要根据系统日期设置日期选择器最大日期为今天日期.我不知道如何将日期选择器最大日期设置为今天日期.任何人都知道帮助我解决这个问题.

我的日期选择器编码是:

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 + …

我DatePicker在Android中使用一个小部件供用户设置日期,并且想要在单击确认按钮时获取日期值,我该怎么做？

我想在打开 dateRangePicker 时显示选定的日期范围，我知道 setSelected 方法就是用于此目的的，我尝试过它不起作用，或者可能做错了什么，请帮助

这是我已经尝试过的

public void openDateRangePicker(View view) {
 MaterialDatePicker.Builder builder =
                MaterialDatePicker.Builder.dateRangePicker();

        CalendarConstraints.Builder constraintsBuilder = new CalendarConstraints.Builder();

        MaterialDatePicker<Pair<Long,Long>> picker = builder.build();
        builder.setCalendarConstraints(constraintsBuilder.build());

        picker.setStyle(DialogFragment.STYLE_NORMAL, R.style.Custom_MaterialCalendar_Fullscreen);
        if(!firstDateStr.isEmpty() || !endDateStr.isEmpty()){
            builder.setSelection(selectionDates);

        }
        picker.show(getSupportFragmentManager(), picker.toString());



    picker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener<Pair<Long, Long>>() {
        @Override
        public void onPositiveButtonClick(Pair<Long, Long> selection) {

            long firstDateLong = selection.first;
            Date firstDate=new Date(firstDateLong);
            long endDateLong = selection.second;
            Date endDate=new Date(endDateLong);

            SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());

            //format yyyy-MM-dd
            firstDateStr = sdf2.format(firstDate);
            endDateStr = sdf2.format(endDate);
            selectionDates = selection;


            selectedDatesStr = firstDateStr + …
