How could i do this?
This is my code:
private void setDateTimeField () {
Calendar newCalendar = Calendar.getInstance();
mDatePickerDialog = new DatePickerDialog(AddBirthday.this, new OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
addBirthdayDate.setText(dateFormatter.format(newDate.getTime()));
dateSelected = String.valueOf(dayOfMonth) + " /" + String.valueOf(monthOfYear + 1)
+ " /" + String.valueOf(year);
}
}, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
}
I would like now to calculate when is birthday of user when he chose the date in DatePickerDialog and storing it in integer type.
You could try with an easier code like this for example:
private int mDay;
private int mMonth;
private int mYear;
private EditText date;
private Calendar c = new Calendar();
...
//and in your onCreate method:
date = (EditText)findViewById(R.id.date_of_birth_as_text);
date.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
showDialog(DATE_DIALOG_ID); //DATE_DIALOG_ID is the id of your DatePickerDialog - declared in your layout file
}
});
//default values of the year, month and date - will be changed after click on the EditText view
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
updateDisplay();
protected Dialog onCreateDialog(int id) {
switch(id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
}
return null;
}
private DatePickerDialog.OnDateSetListener mDateSetListener= new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, monthOfYear);
c.set(Calendar.DAY_OF_MONTH, dayOfMonth);
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
updateDisplay();
}
};
private void updateDisplay() {
Date currentDate = new Date();
int age = currentDate.getYear() - mYear;
date.setText( new StringBuilder().append("The user is ")
.append(age).append(" years old"));
}
int age = getCurrentYear() -datePicker.getYear() ;

Calendar calender = Calendar.getInstance();
final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(LabCheckOutActivity.this,
myDateListener, calender.get(Calendar.YEAR), calender.get(Calendar.MONTH),
calender.get(Calendar.DAY_OF_MONTH)+1);
pickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()-1000);
pickerDialog.show();
by Using this code, in dialog date is pointed to tomorrow but user can also select todays date.I want user can select date from tomorrow not today.
public class CustomDatePickerDialog extends DatePickerDialog {
int maxYear;
int maxMonth;
int maxDay;
public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
super(context, callBack, year, monthOfYear, dayOfMonth);
}
public void setMaxDate(long maxDate) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
getDatePicker().setMaxDate(System.currentTimeMillis());
} else {
final Calendar c = Calendar.getInstance();
c.setTimeInMillis(maxDate);
maxYear = c.get(Calendar.YEAR);
maxMonth = c.get(Calendar.MONTH);
maxDay = c.get(Calendar.DAY_OF_MONTH);
}
}
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
super.onDateChanged(view, year, monthOfYear, dayOfMonth);
} else {
if (year > maxYear)
view.updateDate(maxYear, maxMonth, maxDay);
if (monthOfYear > maxMonth && year == maxYear)
view.updateDate(maxYear, maxMonth, maxDay);
if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
view.updateDate(maxYear, maxMonth, maxDay);
}
}
}
Use
pickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()+24*60*60*1000);//where 24*60*60*1000 represents the total timestamp for one day
instead of
pickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()-1000);
Please see complete implementation below:
DialogFragment class
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener
{
public DatePickerFragment()
{
}
public void setiDateTimeListener(IDateTimeListener iDateTimeListener)
{
this.iDateTimeListener = iDateTimeListener;
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), this, year, month, day);
// Set minimum date as tommorw
datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() + 24*60*60*1000);
// If need to set max date then use this also
// datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
// Create a new instance of DatePickerDialog and return it
return datePickerDialog;
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
try
{
String selectedDt = dayOfMonth+"-"+(monthOfYear + 1)+"-"+year;
iDateTimeListener.onDateSet(selectedDt);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
Interface must be implemented in date picker calling class
public interface IDateTimeListener
{
public void onDateSet(String date);
}
Calling dialog fragment
public void showDatePickerDialog()
{
DatePickerFragment datePickerFragment = new DatePickerFragment();
datePickerFragment.setiDateTimeListener(this);
datePickerFragment.show(getActivity().getSupportFragmentManager(),"datePicker");
}
if (CustomVerticalCalendarView.isPreviousDateDisabled()) { // disable previous date disable flow
int daysOfYear = listCalender.get(Calendar.DAY_OF_YEAR);
int currentDate = today.get(Calendar.DAY_OF_YEAR);
int listYear = listCalender.get(Calendar.YEAR);
int currentYear = today.get(Calendar.YEAR);
if (daysOfYear < currentDate || listYear < currentYear) {
checkBox.setEnabled(false);
checkBox.setTextColor(ContextCompat.getColor(checkBox.getContext(), R.color.dark_gray));
}
}
Hope this code helps you.
When I run and click the button, it does not open the datapicker dialogbox. I am not able to find out what is incorrect. Please, any one can check and guide me where is the incorrect code in the program.

I am doing datepicker. I am facing some challenges. I am checking wheather selected date is weekend or not. If it is weekend then it should give current date only. Now I don't know where should I put condition in this program and how to get the day of the week and against which thing I should check.
Please, help me.

Hi am using Date picker in more than three class with same validation. Instead I must write in one class and call that function in other classes when I required, is it possible Below code for Date picker.
public class MainActivity extends Activity {
private TextView tvDisplayDate;
private Button btnChangeDate;
private int myear;
private int mmonth;
private int mday;
static final int DATE_DIALOG_ID = 999;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setCurrentDateOnView();
addListenerOnButton();
}
// display current date
public void setCurrentDateOnView() {
tvDisplayDate = (TextView) findViewById(R.id.tvDate);
final Calendar c = Calendar.getInstance();
myear = c.get(Calendar.YEAR);
mmonth = c.get(Calendar.MONTH);
mday = c.get(Calendar.DAY_OF_MONTH);
// set current date into textview
tvDisplayDate.setText(new StringBuilder()
// Month is 0 based, just add 1
.append(mmonth + 1).append("-").append(mday).append("-")
.append(myear).append(" "));
}
public void addListenerOnButton() {
btnChangeDate = (Button) findViewById(R.id.btnChangeDate);
btnChangeDate.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
DatePickerDialog _date = new DatePickerDialog(this, datePickerListener, myear,mmonth,
mday)
{
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
if (year < myear)
view.updateDate(myear, mmonth, mday);
if (monthOfYear < mmonth && year == myear)
view.updateDate(myear, mmonth, mday);
if (dayOfMonth < mday && year == myear && monthOfYear == mmonth)
view.updateDate(myear, mmonth, mday);
}
};
return _date;
}
return null;
}
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
myear = selectedYear;
mmonth = selectedMonth;
mday = selectedDay;
// set selected date into textview
tvDisplayDate.setText(new StringBuilder().append(mmonth + 1)
.append("-").append(mday).append("-").append(myear)
.append(" "));
Date dateObject1 = new Date(myear - 1900, mmonth, mday);
Date dateObj2 = new Date(System.currentTimeMillis());
if(dateObject1.before(dateObj2) || dateObject1.equals(dateObj2)){
//the program runs normally
}
else{
new AlertDialog.Builder(MainActivity.this)
.setTitle("Wrong Data Input!")
.setMessage("The end Date must be Before the start Date, please insert new Date values")
.setNeutralButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
}
}).show();
}
}
};
}
You could have a DateUtils class with a static method, which takes in the dates, along with the context. This method can do the date validations and build the AlertDialog accordingly. You can call this static method this way.
DateUtils.dateValidator(Date, Context);
This can be called in the onDateSet() of your OnDateSetListener for each DatePicker.
I have created datePicker dialog in Java file. This is a code:
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
//return new DatePickerDialog(getActivity(), (EditSessionActivity)getActivity(), year, month, day);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
mDateDisplay .setText(String.valueOf(day) + "/"
+ String.valueOf(month + 1) + "/" + String.valueOf(year));
// set selected date into datepicker also
}
}
I want to add ID to my DatePicker. How can I do it from Java file.
Check it:
static final int DATE_DIALOG_ID = 999;
showDialog(DATE_DIALOG_ID);
override the following:
protected Dialog onCreateDialog(int id) {
Calendar c = Calendar.getInstance();
int cyear = c.get(Calendar.YEAR);
int cmonth = c.get(Calendar.MONTH);
int cday = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(this, mDateSetListener, cyear, cmonth, cday);
}
Also I need a Listner:
private DatePickerDialog.OnDateSetListener datePickerListener
= new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
year = selectedYear;
month = selectedMonth;
day = selectedDay;
//set selected date into textview
tvDisplayDate.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
// set selected date into datepicker also
dpResult.init(year, month, day, null);
}
};
Its always good to take a look at android API reference. Take a look at this and this
Anyway as an answer you can do the following
DatePicker picker=datePickerDialog.getDatePicker();
picker.setId("picker");
