Converting picked date time dialog picker to store in sqlite DB

I have created a DatePicker within my app. But the problem I am trying to overcome is how to take the picked date and store it in my database:
In my DB, the date field is set to TEXT
private int mYear, mMonth, mDay, mHour, mMinute;
#Override
public void onClick(View v) {
final Calendar calendar = Calendar.getInstance();
//Get the date
if (v == buttonDatePicker) {
mYear = calendar.get(Calendar.YEAR);
mMonth = calendar.get(Calendar.MONTH);
mDay = calendar.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
etDate.setText(dayOfMonth + "-" + month + "-" + year);
mYear = year;
mMonth = month;
mDay = dayOfMonth;
}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
//Get the time
if (v == buttonTimePicker) {
mHour = calendar.get(Calendar.HOUR_OF_DAY);
mMinute = calendar.get(Calendar.MINUTE);
TimePickerDialog timePickerDialog = new TimePickerDialog(this,
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
etTime.setText(hourOfDay + ":" + minute);
mHour = hourOfDay;
mMinute = minute;
}
}, mHour, mMinute, true);
timePickerDialog.show();
}
}
I tried to convert the picked Year etc from int to String but it does not seem to like it when I tried to cast it.
How I am trying to store it in my DB :
typedUpSmsMessage = smsMessage.getText().toString();
ContentValues cv = new ContentValues();
cv.put("textMessage", typedUpSmsMessage);
cv.put("dateToSendText",mYear + mMonth + mDay);
cv.put("gameID", gameID);
automateGameDB.insert("automateGames", null, cv);
But ofcourse since the date is in int, it just adds the numbers.
Need to convert them into a string, or a date format? (yyyy-mm-dd hh-mm-ss)?
Thanks

Since the field is Text you should use cv.put("dateToSendText", year + "-" + month + "-" + dayOfMonth) with 4 digit year and 2 digit month and dayOfMonth, because it is comparable and sortable.

Insert your date in database like
cv.put("dateToSendText",dayOfMonth + "-" + month + "-" + year)
or
cv.put("dateToSendText",etTime.gettext().tostring());

Really don't understand your requirement.
Will this code
String string = Integer.toString(int); or String.valueOf(int) or simply string+""
solve your problem?

I advise you to store Date as a timestamp in your database :
Calendar calendar = Calendar.getInstance()
calendar.set(year, month, day, hour, minute, second)
Long timestamp = calendar.getTimeInMillis() // Save timestamp in database

Use
inputDate = mYear +"-"+ mMonth +"-"+ mDay;
SimpleDateFormat src = new SimpleDateFormat("yyyy-MM-dd", Locale.US);
SimpleDateFormat dest = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss", Locale.US);
Date date = null;
try {
date = src.parse(inputDate);
} catch (ParseException e) {
Log.d("Exception",e.getMessage());
}
String formattedDate = dest.format(date);
You can change dest Dateformat as u want...
Use 'TEXT' datatype in sqlite to store this date field

How can I properly format the date on Android? [duplicate]

This question already has answers here:
How to format date and time in Android?
(26 answers)
Closed 5 years ago.
I am building an IOS and Android version and in my IOS, the date is formatted this way "June 23, 2017 at 8:58 AM".
In Android I am getting the date in numbers and then I assign them like this:
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
date_time = dayOfMonth + "-" + (monthOfYear + 1) + "-" + year;
timePicker();
}
and here is the timePicker() method:
private void timePicker(){
// Get Current Time
final Calendar c = Calendar.getInstance();
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);
// Launch Time Picker Dialog
TimePickerDialog timePickerDialog = new TimePickerDialog(this,
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mHour = hourOfDay;
mMinute = minute;
et_show_date_time.setText(date_time+" "+hourOfDay + ":" + minute);
}
}, mHour, mMinute, false);
timePickerDialog.show();
}
which result to something like this "27-6-2017 16:55"
How can I formatted similar to the IOS version?

You can do this by SimpleDateFormat
Date currentTime = Calendar.getInstance().getTime();
String newFormat="";
try
{
SimpleDateFormat form = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss");
newFormat = form.format(currentTime);
tvAppliedDate.setText(newFormat);
}
catch (Exception e)
{
e.printStackTrace();
Toast.makeText(this, "parse error", Toast.LENGTH_SHORT).show();
}

Android DatePicker setOnClickListener

I have 2 android datepickers and I want to get the dayOfWeek in each date picker but I get only the initial calendar day even if I change it. How to set the clickListener? I would like to get the day of the week in dayOfWeek and dayOfWeek1 variables.
dpTake=(DatePicker) rootView.findViewById(R.id.dpTake);
dpDelivery=(DatePicker) rootView.findViewById(R.id.dpDelivery);
Date dt = new Date();
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
dpDelivery.updateDate(c.YEAR, c.MONTH, c.DAY_OF_MONTH);
c.add(Calendar.DATE, 1);
dt = c.getTime();
dpTake.setMinDate(dt.getTime());
CalendarView cv = dpTake.getCalendarView();
long current = cv.getDate();
cv.setDate(cv.getMaxDate(), false, true);
cv.setDate(current, false, true);
c.add(Calendar.DATE, 2);
dt = c.getTime();
dpDelivery.setMinDate(dt.getTime());
CalendarView cvDelivery = dpDelivery.getCalendarView();
current = cvDelivery.getDate();
cvDelivery.setDate(cv.getMaxDate(), false, true);
cvDelivery.setDate(current, false, true);
dayOfWeek1 = c.get(Calendar.DAY_OF_WEEK);

Try this code
DatePickerDialog dpd = DatePickerDialog.newInstance(
new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, monthOfYear);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
}
},
calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH)
);
dpd.setAccentColor(Color.parseColor("#029789"));
dpd.setMinDate(Calendar.getInstance());
dpd.show(getActivity().getFragmentManager(), "Datepickerdialog");

Get interval date in Android?

I want interval date. Whatever user enter date from date picker and from this date I want to get after one month date Suppose 1 Aug 2014 -> Output will be 1 September 2014.Can someone help me .Thanks to appreciate.
Hare is my Activity code

What you want to do is add() one Calendar.MONTH to a date that you've gotten and parsed, etc. so I won't go into that. I'll assume you are handling everything correctly up to the point where you'd like to get the same day, if possible, of the next month.
Part of your problem, as your comment suggests, is Calendar.getInstance() does not have an implementation that takes a Date. But more importantly you don't need it. You have a Date and a Calendar instance and it seems like you're changing c2 anyway so why not use Calendar's setTime() method like this?
// setting c2 with the convertedDate then adding a month
c2.setTime(convertedDate);
c2.add(Calendar.MONTH, 1);
// Simple example
public static void main(String...args) {
Date d = new Date();
Calendar c = Calendar.getInstance();
c.setTime(d);
System.out.println(c.getTime());
c.add(Calendar.MONTH, 1);
System.out.println(c.getTime());
}

try to use this.
Calendar c = Calendar.getInstance();
int month = c.get((Calendar.MONTH));
c.set(Calendar.MONTH, month + 1);
long time = c.getTimeInMillis();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String result = sdf.format(new Date(time1));

To get start date and end date of months between the given dates range

i want to make a list of dates between the given date range like--
ex: fromDate - 15/10/2013 and toDate - 15/12/2013
now the list should be
[ 15/10/2013, 31/10/2013, 1/1/2013, 30/11/2013, 1/12/2013, 15/12/2013 ]
i have written this code ---
private List<Date> datesList = new ArrayList<Date>();
public void findLastDate(){
Date lastDateOfMonth;
Date firstDateOfNextMonth = null;
datesList.add(fromDate);
do {
Calendar calendar = Calendar.getInstance();
if(firstDateOfNextMonth == null){
calendar.setTime(fromDate);
} else {
calendar.setTime(firstDateOfNextMonth);
}
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DAY_OF_MONTH, 1);
calendar.add(Calendar.DATE, -1);
lastDateOfMonth = calendar.getTime();
datesList.add(lastDateOfMonth);
Calendar calendar2 = Calendar.getInstance();
calendar2.setTime(lastDateOfMonth);
calendar2.add(Calendar.MONTH, 1);
calendar2.set(Calendar.DAY_OF_MONTH, 1);
calendar2.add(Calendar.DATE, 0);
firstDateOfNextMonth = calendar2.getTime();
datesList.add(firstDateOfNextMonth);
} while(firstDateOfNextMonth.compareTo(toDate) < 0);
datesList.add(toDate);
System.out.println("List of dates " + datesList);
}
but i am getting a list as
[15/10/2013, 31/10/2013, 1/1/2013, 30/11/2013, 1/12/2013, 30/12/2013, 1/1/2014, 15/12/2013]
the dates 30/12/2013, 1/1/2014 should not be in the list so what should be the condition in while loop i am not getting it plz help me out...

Basically, you should be doing 2 things.
After you add a value to the Calendar, you need to be checking to see if that is now after the end time and
Unless it's equal to the end time, removing the last date from the list
For Example
List<Date> dates = new ArrayList<>(25);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DATE, 15);
cal.set(Calendar.MONTH, 9);
cal.set(Calendar.YEAR, 2013);
Calendar endCal = Calendar.getInstance();
endCal.set(Calendar.DATE, 15);
endCal.set(Calendar.MONTH, 11);
endCal.set(Calendar.YEAR, 2013);
dates.add(cal.getTime());
while (cal.before(endCal)) {
cal.set(Calendar.DATE, cal.getActualMaximum(Calendar.DATE));
dates.add(cal.getTime());
if (cal.before(endCal)) {
cal.add(Calendar.DATE, 1);
dates.add(cal.getTime());
}
}
dates.remove(dates.size() - 1);
dates.add(endCal.getTime());
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
for (Date d : dates) {
System.out.println(sdf.format(d));
}
Will output
15/10/2013
31/10/2013
01/11/2013
30/11/2013
01/12/2013
15/12/2013
Updated with example, based on original code
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DATE, 15);
cal.set(Calendar.MONTH, 9);
cal.set(Calendar.YEAR, 2013);
Date fromDate = cal.getTime();
Calendar endCal = Calendar.getInstance();
endCal.set(Calendar.DATE, 15);
endCal.set(Calendar.MONTH, 11);
endCal.set(Calendar.YEAR, 2013);
Date toDate = endCal.getTime();
List<Date> datesList = new ArrayList<>(25);
datesList.add(fromDate);
Calendar calendar = Calendar.getInstance();
calendar.setTime(fromDate);
do {
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DAY_OF_MONTH, 1);
calendar.add(Calendar.DATE, -1);
if (calendar.getTime().before(toDate)) {
datesList.add(calendar.getTime());
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DAY_OF_MONTH, 1);
calendar.add(Calendar.DATE, 0);
if (calendar.getTime().before(toDate)) {
datesList.add(calendar.getTime());
}
}
} while (calendar.getTime().before(toDate));
datesList.add(toDate);
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
for (Date d : datesList) {
System.out.println(sdf.format(d));
}
Which outputs...
15/10/2013
31/10/2013
01/11/2013
30/11/2013
01/12/2013
15/12/2013
Note: The one thing that neither of these code snippets are doing is check to see if the last date in the list is actually the end date (although from the looks of it, yours seems to be able to get around this need)
