Java TimePicker does not return right value

Java TimePicker does not return right value - java

In android project I have this class
package mycalories.com.jalle.mycalories;
import android.app.Dialog;
import android.app.DialogFragment;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.text.format.DateFormat;
import android.text.format.Time;
import android.widget.TimePicker;
import java.util.Calendar;
public class TimePickerFragment extends DialogFragment implements
TimePickerDialog.OnTimeSetListener {
public static interface OnTimeSetListener {
void onTimeSet(Time time);
}
private OnTimeSetListener onTimeSetListener;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
return new TimePickerDialog(getActivity(), this, hour, minute,
DateFormat.is24HourFormat(getActivity()));
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
if (onTimeSetListener != null) {
Time newTime =new Time(hourOfDay+":"+minute+ "");
onTimeSetListener.onTimeSet(newTime);
}
}
public void setOnTimeSetListener(OnTimeSetListener onTimeSetListener) {
this.onTimeSetListener = onTimeSetListener;
}
}
that should return Time selected. And in the main activity I have button and a text field:
Button btnTime = (Button) findViewById(R.id.btnTime);
btnTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
TimePickerFragment timePicker = new TimePickerFragment();
timePicker.show(getFragmentManager(), "timePicker");
timePicker.setOnTimeSetListener(new OnTimeSetListener() {
#Override
public void onTimeSet(Time time) {
// SimpleDateFormat HHMM = new SimpleDateFormat("hh:mm");
final EditText txtTime = (EditText) findViewById(R.id.txtTime);
txtTime.setText(time.toString());
}
});
}
});
After selecting time I should have in format hh:mm but instead I got 19700101T00000011:55(4,0,0,0,0)
(obviously current time is not selected but default one)
I guess that the method onTimeSetis not right. Any idea ?
And one more q : How do I use same TimePicker class for multiple textboxes in diff activities ?

Time API has 3 constructors: no argument, String argument, and other Time argument. The constructor you are using, which is the String one, only accepts timezone as the expected value, and it will set the date to Jan 1, 1970.
public Time (String timezone)
Construct a Time object in the timezone named by
the string argument "timezone". The time is initialized to Jan 1,
1970.
If you want to return the Time with today's date and selected time, try changing the code to
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
if (onTimeSetListener != null) {
Time newTime = new Time();
newTime.setToNow();
newTime.hour = hourOfDay;
newTime.minute = minute;
onTimeSetListener.onTimeSet(newTime);
}
}

Knowing that you eventually want to display the time in hh:mm format, it would be easier to implement your interface method using the java.util.Date class, which SimpleDateFormat "plays nice" with. In the TimePickerFragment class, change the following:
public static interface OnTimeSetListener {
void onTimeSet(Date date);
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
if (onTimeSetListener != null) {
Date date = new Date();
date.setHours(hourOfDay);
date.setMinutes(minute);
onTimeSetListener.onTimeSet(date);
}
}
And in the onClick() method:
public void onClick(View v)
{
TimePickerFragment timePicker = new TimePickerFragment();
timePicker.show(getFragmentManager(), "timePicker");
timePicker.setOnTimeSetListener(new TimePickerFragment.OnTimeSetListener() {
#Override
public void onTimeSet(Date date)
{
final EditText txtTime = (EditText) findViewById(R.id. txtTime);
SimpleDateFormat HHMM = new SimpleDateFormat("hh:mm");
txtTime.setText(HHMM.format(date));
}
}
);
}

Setting up a start date and a end date to store into a firebase cloud?

Currently, I am creating a calendar app that will essentially have an employee choose a start date and an end date. The duration chosen between these dates will be the employees chosen holiday.
Now the problem is that I need to store 2 dates, which are the start date and the end date, into a firebase database. I intend to use this information later on so that I can compare the dates with other employees who may take the same week off (so validation will be needed). However, with my current code, I am only able to create a start date but not an end date, I am also unable to store information into the cloud, but I struggle to understand how I can retrieve the data in its current form.
For further clarification what I am trying to achieve is: I will have 2 buttons, startDateBtn and endDateBtn, both will initialize a calendar, the dates chosen will be stored/returned as strings and the data will be retrieved by a 3rd button called bookDatesBtn. This button will save the data into the cloud.
What I have tried:
Used a boolean variable set to false, if the startDateBtn is initialized the boolean variable is set to true, this will trigger an if-else statement and will set information for start date as a string. If the endDateBtn is initialized then the boolean variable will be set to false, this will keep information for the end date as a string.

This is my personal use code and it's working fine for my all device I think you should try this code...
I want to know which firebase database you have to use so after I can suggest it .. firebase real-time OR Cloud-firestore for store data...
for the whole code Visit My Code Link - https://github.com/axarlotwala/CafeDelear/blob/master/app/src/main/java/com/cafedelear/aksha/cafedelear/Fragment/ProductOfferFragment.java
/*method of start offer*/
private void offerStart() {
final Calendar calendar = Calendar.getInstance();
myear = calendar.get(Calendar.YEAR);
dmonth = calendar.get(Calendar.MONTH);
mdate = calendar.get(Calendar.DAY_OF_MONTH);
dialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
start_date.setText(year + "-" + (month+1) + "-" + dayOfMonth);
}
},myear,dmonth,mdate);
dialog.show();
dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());
}
private void offerEnd(){
final Calendar calendar = Calendar.getInstance();
myear = calendar.get(Calendar.YEAR);
dmonth = calendar.get(Calendar.MONTH);
mdate = calendar.get(Calendar.DAY_OF_MONTH);
calendar.roll(Calendar.DATE,1);
dialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
end_date.setText(year + "-" + (month+1) + "-" + dayOfMonth);
}
},myear,dmonth,mdate);
dialog.show();
dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());
//if offer end date is selected is also start Offer date then offer end time is Date-23-59-59
}

here is you can understand for previous or new date in your textview first set then use it
previous date:
public void previousDate(Context context, TextView textView) {
mCalendarAlarm = Calendar.getInstance();
mCalendarAlarm.setTimeZone(TimeZone.getDefault());
DatePickerDialog datePickerDialog =
new DatePickerDialog(context, (view, year, monthOfYear, dayOfMonth) -> {
mCalendarAlarm.set(Calendar.YEAR, year);
mCalendarAlarm.set(Calendar.MONTH, monthOfYear);
mCalendarAlarm.set(Calendar.DAY_OF_MONTH, dayOfMonth);
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
String datetime = dateFormat.format(mCalendarAlarm.getTime());
textView.setText(datetime);
}, mCalendarAlarm.get(Calendar.YEAR), mCalendarAlarm.get(Calendar.MONTH),
mCalendarAlarm.get(Calendar.DAY_OF_MONTH));
datePickerDialog.getDatePicker().
setMaxDate(mCalendarAlarm.getTimeInMillis());
datePickerDialog.show();
}
for next date:
public void NextDate(Context context, TextView textView) {
mCalendarAlarm = Calendar.getInstance();
mCalendarAlarm.setTimeZone(TimeZone.getDefault());
DatePickerDialog datePickerDialog =
new DatePickerDialog(context, (view, year, monthOfYear, dayOfMonth) -> {
mCalendarAlarm.set(Calendar.YEAR, year);
mCalendarAlarm.set(Calendar.MONTH, monthOfYear);
mCalendarAlarm.set(Calendar.DAY_OF_MONTH, dayOfMonth);
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
String datetime = dateFormat.format(mCalendarAlarm.getTime());
textView.setText(datetime);
}, mCalendarAlarm.get(Calendar.YEAR), mCalendarAlarm.get(Calendar.MONTH),
mCalendarAlarm.get(Calendar.DAY_OF_MONTH));
datePickerDialog.getDatePicker().
setMinDate(mCalendarAlarm.getTimeInMillis());
datePickerDialog.show();
}

Time Picker is not working when i set time 12:00 or 00:00 its displaying AM instead Pm

when i select 12:00 or i Select 0:00 it showing me only AM not PM tried a lot but not getting the required output and I search same question in stack overflow but not getting the output..
Here the complete code is as follow:-

Error coverting Integer variables to Date Object and value returned is always 31-DEC - 1?

I have written this line of code of code:
dateSelected = new GregorianCalendar(tempYear, tempMonth, tempDate,tempHour,tempMinute).getTime();
I got these value from datepicker and timepicker dialogs in android. I am able to get correct values in these integer variables but when I convert them to Date object it will always be 31 dec. I am not able to fix the problem.
I have also tried this approach as well:
Calendar calendar = Calendar.getInstance();
calendar.set(tempYear, tempMonth, tempDate, tempHour, tempMinute);
dateSelected = calendar.getTime();
Whenever Second line is commented out it is working fine. I am perfectly getting current date and time. But when it is uncommented the problem returns.
In case anyone needs my full code:

setResult(Activity.RESULT_OK, resultIntent);

When the code works all variables equal to 0 because a user doesn't pick a date and a time at the moment.
Calendar calendar = Calendar.getInstance();
calendar.set(tempYear, tempMonth, tempDate, tempHour, tempMinute);
dateSelected = calendar.getTime();
Move the code in addEntry's onClickListener implementation and it will work 👍

I would like to add the mechanism that will allow user to insert dates of holidays (this aplication will calculate the salary and holidays means no salary, so it's important).
As I saw here, user SimplyPanda suggested adding an ArrayList<Integer> to do so. However, I wondering how the inserting by user should look like.
Should user know the integer representation of particular dates in Java? - I guess no.
Does anyone have any idea how to implement such functionality?

I have a UI Lab for Android Programming that I'm trying to complete. I think I'm close, yet so far away. I have four activities that I'm working with but only three of them needed worked on. Here is what I have. I need help with what I'm missing.
Here's the first Activity which is AddToDoActivity

Any thought on how to improve the cancelButton code in the AddToDoAcitivity?

#Override
