I want to pass Date and Time I got using Datepicker Dialog and Timepicker Dialog to next Activity in Android studio

This is the Java code that Datepicker and Timepicker work. Those two are working properly so I want to send that selected date and time to the next activity(Doctor_Time_Picking_data_page.java)
Doctor_Time_Picking_page.java
public class Doctor_Time_Picking_page extends AppCompatActivity {
public static final String TEXT_TO_SEND ="com.example.dogapp.TEXT_TO_SEND";
private DatePickerDialog datePickerDialog;
private Button dateButton;
private Button timeButton;
private Bundle savedInstanceState;
private Button saveButton;
private String DATE;
//On Create method-------------------------------------------------------------------------------------------------------------------------
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_doctor_time_picking_page);
initDatePicker();
dateButton = findViewById(R.id.datePickerButton);
timeButton = findViewById(R.id.timeButton);
saveButton = findViewById(R.id.date_time_save_button);
Intent intent = new Intent(getApplicationContext(),Doctor_Time_Picking_data_page.class);
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(intent);
}
});
}
//-----------------------------------------------------------------------------------------------------------------------------------
private Bundle initDatePicker()
{
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener()
{
#Override
public void onDateSet(DatePicker datePicker, int year, int month, int day)
{
month = month + 1;
String date = makeDateString(day, month, year);
dateButton.setText(date);
}
};
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
int style = AlertDialog.THEME_HOLO_LIGHT;
datePickerDialog = new DatePickerDialog(this, style, dateSetListener, year, month, day);
datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
return null;
}
private String makeDateString(int day, int month, int year)
{
return getMonthFormat(month) + " " + day + " " + year;
}
private String getMonthFormat(int month)
{
if(month == 1)
return "JAN";
if(month == 2)
return "FEB";
if(month == 3)
return "MAR";
if(month == 4)
return "APR";
if(month == 5)
return "MAY";
if(month == 6)
return "JUN";
if(month == 7)
return "JUL";
if(month == 8)
return "AUG";
if(month == 9)
return "SEP";
if(month == 10)
return "OCT";
if(month == 11)
return "NOV";
if(month == 12)
return "DEC";
//default should never happen
return "JAN";
}
public void openDatePicker(View view)
{
datePickerDialog.setTitle("Select Date");
datePickerDialog.show();
}
//Time Button
int hour, minute;
public void popTimePicker(View view)
{
TimePickerDialog.OnTimeSetListener onTimeSetListener = new TimePickerDialog.OnTimeSetListener()
{
#Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute)
{
hour = selectedHour;
minute = selectedMinute;
timeButton.setText(String.format(Locale.getDefault(), "%02d:%02d",hour, minute));
}
};
TimePickerDialog timePickerDialog = new TimePickerDialog(this, /*style,*/ onTimeSetListener, hour, minute, true);
timePickerDialog.setTitle("Select Time");
timePickerDialog.show();
}
}
This is the page where I want to show the date and Time selected form my previous activity(Doctor_Time_Picking_page.java)
Doctor_Time_Picking_data_page.java:
public class Doctor_Time_Picking_data_page extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_doctor_time_picking_data_page);
Button Button1a = findViewById(R.id.doc_page4_btn1);
Button Button2a = findViewById(R.id.doc_page4_btn2);
Button Button3a = findViewById(R.id.doc_page4_btn3);
Dialog nDialog = new Dialog(this);
Button1a.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(Doctor_Time_Picking_data_page.this,Doctor_Appoinment_payment.class);
startActivity(intent);
}
});
Button2a.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(Doctor_Time_Picking_data_page.this,Doctor_Time_Picking_page.class);
startActivity(intent);
}
});
Button3a.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
nDialog.setContentView(R.layout.activity_doctor_delete_popup_msg);
nDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
Intent intent = new Intent(Doctor_Time_Picking_data_page.this,Doctor_delete_popup_msg.class);
startActivity(intent);
}
});
}
}
In my project there are three buttons those are Select Time, Select Date and save button when I select each button Datepicker and Timepicker dialogues appear when I select Date or time those Data is appearing on the Buttons I want to pass those data to my next activity which is Doctor_Time_Picking_data_page.java and display them to user. What I now want is I want to pass That data selected from those Pickers to next activity

You need to pass an intent extra to the other activity to get your result. Follow the steps:
Create a filed name date in your class:
private String date = "JAN 1 2022"; // I have given a sample date
You need to store the date inside the DateSetListener like this:
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener()
{
#Override
public void onDateSet(DatePicker datePicker, int year, int month, int day)
{
month = month + 1;
date = makeDateString(day, month, year);
dateButton.setText(date);
}
};
You need to pass that date on the click of the save button:
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
intent.putExtra("date", date);
startActivity(intent);
}
});
Then you need to get that date on the other activity like this:
public class Doctor_Time_Picking_data_page extends AppCompatActivity {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_doctor_time_picking_data_page);
String date = getIntent().getStringExtra("date", "");
// 👆 that is the date from the previous activity
...
});
...
}

Android DatePicker dialog, date should come from tomorrow

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.

To store DateTime value into php and mysql

I am working on how to put Date value into my PHP/MySQL using android's date picker.
I want to make a Sharing Parking lot application that owner can register one's parking place with its information like operating time. Then user can use it with choosing the beginning and ending points.
I searched a lot but need more specific information.
How can I save operating time slot into PHP/MySQL?
The following is my android java code.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

How to calculate age based on picked date in DatePickerDialog android?

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() ;

Datepicker dialog box does not open on click

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.
