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: 
```
**new Way**

 ed_date.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Calendar mcurrentDate=Calendar.getInstance();
                year=mcurrentDate.get(Calendar.YEAR);
                month=mcurrentDate.get(Calendar.MONTH);
                day=mcurrentDate.get(Calendar.DAY_OF_MONTH);

                final DatePickerDialog   mDatePicker =new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener()
                {
                    @Override
                    public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday)
                    {
                              ed_date.setText(new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
                            int month_k=selectedmonth+1;

                    }
                },year, month, day);
                mDatePicker.setTitle("Please select date");
                // TODO Hide Future Date Here
                mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());

                // TODO Hide Past Date Here
                //  mDatePicker.getDatePicker().setMinDate(System.currentTimeMillis());
                mDatePicker.show();
            }
        }); 

```
In kotlin , we can also pass this in setMaxDate(Date().time-86400000)

For example

```
dpd.datePicker.setMaxDate(Date().time - 86400000)
dpd.show()

```

here I am using dpd as object of DatePickerDialog. And there are 86400000 milliseconds in a day so I am setting the max date to be allowed a day before the current date. This will disable the future dates in calender.
