public  void CalenderView() {

          /* ends after 1 month from now */
            Calendar endDate = Calendar.getInstance();
            endDate.add( Calendar.DAY_OF_WEEK_IN_MONTH, 1 );

            HorizontalCalendar horizontalCalendar = new HorizontalCalendar.Builder( this, R.id.calendarView )
                    .range( Calendar.getInstance(), endDate )
                    .datesNumberOnScreen( 5 )
                    .configure()
                    .formatTopText( "EEE" )

                    //Display the TimePicker current time to app interface

                        //Get the current hour as AM PM 12 hour format
                        hourOfDay = hourOfDay-12;
                        AMPM = "PM";
                    }
                    tv.setText("" + hourOfDay + ":" + minute + ":" + AMPM);
                }

如果你想要禁用传递日期，那么在下面的代码中使用datepicker视图..

datePicker.setMinDate(System.currentTimeMillis() - 1000);

然后使用DatePickerDialog然后在代码下面使用...

datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);

并且您在两种方法下使用的时间和日期不会显示...

    /**
 * to display date picker dialog
 */
private void showDatePicker() {
    if (mEventDatePickerDialog == null) {
        if (newCalendar == null) {
            newCalendar = Calendar.getInstance();
        }
        mEventDatePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {

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

                newDate = Calendar.getInstance();
                newDate.set(year, monthOfYear, dayOfMonth);
                newCalendar.set(Calendar.YEAR, year);
                newCalendar.set(Calendar.MONTH, monthOfYear);
                newCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                // newCalendar.setTimeInMillis(System.currentTimeMillis());
                showTimePicker();

                //mTvEventDate.setText(dateFormatter.format(newDate.getTime()));
            }
        }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
        mEventDatePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
        mEventDatePickerDialog.show();
    } else if (mEventDatePickerDialog != null && !mEventDatePickerDialog.isShowing()) {
        if (newCalendar == null) {
            newCalendar = Calendar.getInstance();
        }
        mEventDatePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {

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

                newDate = Calendar.getInstance();
                newDate.set(year, monthOfYear, dayOfMonth);
                newCalendar.set(Calendar.YEAR, year);
                newCalendar.set(Calendar.MONTH, monthOfYear);
                newCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                // newCalendar.setTimeInMillis(System.currentTimeMillis());
                showTimePicker();
                //mTvEventDate.setText(dateFormatter.format(newDate.getTime()));
            }
        }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
        mEventDatePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
        mEventDatePickerDialog.show();
    }

如果您使用的是Android DatePicker，则可以将最短日期设置为今天的日期，因此不会启用今天之前的日期。您可以使用此代码段：

datePicker.setMinDate(new Date().getTime());

否则，如果您使用的是DatePickerDialog：

datePickerDialog.getDatePicker().setMinDate(new Date().getTime());

如何在android中的timepicker上禁用过去的时间
