日期选择器对话框不能选择过去的日期

Question

I am using datepicker dialog in my app. I dont want to select passed dates when user selects any date from Dialog. My code is here.

private DatePickerDialog.OnDateSetListener mdateSetListener = new DatePickerDialog.OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int yr, int monthOfYear,
            int dayOfMonth) {
        year = yr;
        month = monthOfYear;
        day = dayOfMonth;
        updateDate();
    }
};

Update date sets the selected date to EditText. Is there any library method to prevent selecting past dates?

Thanks in Advance

Answer 1

In update method your condition would be .Date class have before ,equals and after methods.Use them.

if(userdate.before(today) || userdate.equals(today)){
   //past date found
}

Answer 2

You can use: getDatePicker().setMaxDate() . Override onCreate() of Dialog and apply limits there.

Answer 3

If using API 11 or greater, you can use DatePicker.setMinDate()

Check http://developer.android.com/reference/android/widget/DatePicker.html#setMinDate(long) for more info.

Also see setMinDate() for DatePicker doesn't work to see how to use it.

Answer 4

if your application requires to run on API LEVEL 8+ then use below way to do it. put the relevant code inside yout onDateSet method.

@Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
String selected_date = dayOf + "-" + monthOf + "-" + year;

            Log.i(TAG, "Selected Date" + selected_date);
            SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
            Date strDate = null;
            try {
                strDate = sdf.parse(selected_date);
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            Calendar c = Calendar.getInstance();
            System.out.println("Current time => " + c.getTime());

            Date current_date = null;
            String formattedDate = sdf.format(c.getTime());
            try {
                current_date = sdf.parse(formattedDate);
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }


            if (current_date.after(strDate)) {
                Toast.makeText(getApplicationContext(),
                        "Please choose future date", 1).show();
            } else {

                mYear = String.valueOf(year);
                mMonth = String.valueOf(monthOfYear);
                mDay = String.valueOf(dayOfMonth);
                updateStartDate();

            }
       }

if your Application require to run on API LEVEL 11+ then use DatePicker.setMinDate(long) you can find more information HERE
