Question: How to Disable future dates in Android date picker

Java Code :

```
mExpireDate.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                // To show current date in the datepicker
                final Calendar mcurrentDate = Calendar.getInstance();
                int mYear = mcurrentDate.get(Calendar.YEAR);
                int mMonth = mcurrentDate.get(Calendar.MONTH);
                int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                 DatePickerDialog mDatePicker = new DatePickerDialog(
                        EventRegisterActivity.this, new OnDateSetListener() {
                            public void onDateSet(DatePicker datepicker,
                                    int selectedyear, int selectedmonth,
                                    int selectedday) {

                                mcurrentDate.set(Calendar.YEAR, selectedyear);
                                mcurrentDate.set(Calendar.MONTH, selectedmonth);
                                mcurrentDate.set(Calendar.DAY_OF_MONTH,
                                        selectedday);
                                SimpleDateFormat sdf = new SimpleDateFormat(
                                        getResources().getString(
                                                R.string.date_card_formate),
                                        Locale.US);

                                mExpireDate.setText(sdf.format(mcurrentDate
                                        .getTime()));
                            }
                        }, mYear, mMonth, mDay);

                mDatePicker.setTitle(getResources().getString(
                        R.string.alert_date_select));
                mDatePicker.show();
            }
        });

How to do it?

Answer: 
If user select future date then update datepicker to current date(today)

you can use following code to check selected is future date or not

```
final Calendar cal = Calendar.getInstance();
datePickerDob.init(currentYear, currentMonth, currentDay,
            new OnDateChangedListener() {

                @Override
                public void onDateChanged(DatePicker view, int year,
                        int monthOfYear, int dayOfMonth) {
                    Calendar selectedCal = Calendar.getInstance();
                    selectedCal.set(year, monthOfYear, dayOfMonth);

                    long selectedMilli = selectedCal.getTimeInMillis();

                    Date datePickerDate = new Date(selectedMilli);
                    if (datePickerDate.after(new Date())) {

                        datePickerDob.updateDate(cal.get(Calendar.YEAR),
                                cal.get(Calendar.MONTH),
                                cal.get(Calendar.DAY_OF_MONTH));

                    } else {

                    }

                }
            });

```

You can also use compareTo() method

```
datePickerDate.compareTo(new Date());

```

Compare the receiver to the specified Date to determine the relative ordering.

Parameters
date a Date to compare against. 

Returns
an int < 0 if this Date is less than the specified Date, 0 if they are equal, and an int > 0 if this Date is greater.
If you using material design Datepicker :

```
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    DatePickerDialog datePickerDialog = DatePickerDialog.newInstance(this,
            calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
    datePickerDialog.show(getFragmentManager(), "datepicker");
    datePickerDialog.setMaxDate(calendar);

```
