Hi does anyone know why i am getting this error in runtime? I am unsure how to resolve it and i am new to this. Please help! I have called the Search class in my MainActivity and my app crashes when i click on the button to open it.
Here is the code used to call the Search class:
search.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, Search.class);
startActivity(intent);
}
});
And here is my Search class:

Your Search class is a Fragment, you cannot start it with the Intent.
Make Search to be Activity or switch between fragments using FragmentManager.
Intent intent = new Intent(MainActivity.this, Search.class);
The Intent constructor doesn't expect a Fragment class as a second Argument, Here you add Search.class which is a Fragment, but you need to have an Activity instead
Fragments can be loaded in activities using a Transaction, not an intent.

I want change the month and year with these two numberpickers but I do not know how to change the date. What I want to do is this: when i click on OK button on BottomSheetDialog I want to set the month and year. Can you help me please? I tried but I couldn't find any solution on the internet. If you help me, I'll be appreciated. Thank you.

Good implementation, proper updated answer:
LocalDate date1 = LocalDate.of(2021, Month.JANUARY, 1);
LocalDate date2 = date1.withYear(2010);
LocalDate date3 = date2.withMonth(Month.DECEMBER.getValue());
LocalDate date4 = date3.withDayOfMonth(15);
LocalDate date5 = date4.with(ChronoField.DAY_OF_YEAR, 100);
Stolen from https://kodejava.org/how-do-i-manipulate-the-value-of-localdate-object/
Bad outdated implementation, bad answer (just here for protocol)
Simple pure Java implementation:
Use Calendar. Create a new instance; you probably want Gregorian Calendar: Calendar.getInstance();
Set the calendar value to the date: cal.setTime(pDate);
adjust single fields: cal.add(pField, pValue); or cal.set(pField, pValue);
retrieve Date object: cal.getTime();
You could also use the new java.time package, with classes like LocalDateTime etc.
And then there's a myriad of Java Date Time libraries out there.
Choose the way that works best for you.
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 have tried with the following link but not getting solution as i want
how to not allow user select past date in datepicker?
Setting upper and lower date limits to date picker dialog
How to set min-max age limit with datepicker android
Date Picker with max and minimum date in onDateChanged() in Android 1.5?
so i am setting date, now when user click on submit button and if the date-picker2's date is lesser than date-picker1's date then alert dialog should come..
So what i am doing wrong, can anyone help me please. Thanks in advance.
Just compare getTimeInMillis of Calendar
Calendar mCalendarFirst = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_frist_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_frist_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_frist_datepicker);
Calendar mCalendarSecond = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_second_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_seconf_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_second_datepicker);
if(mCalendarSecond.getTimeInMillis() <= mCalendarFirst.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Update:
For your situation use below:
if(Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Try Below code:
public void onClick(View v) {
switch (v.getId()) {
case R.id.submit:
Code.title = editTextTitle.getText().toString().trim();
Code.description = editTextDesc.getText().toString().trim();
Code.diff = Code.DueDate.getTimeInMillis()
- Code.AssignDate.getTimeInMillis();
Code.days = Code.diff / (24 * 60 * 60 * 1000);
Code.strDays = String.valueOf(Code.days);
Date assignDate = new Date(Code.AssignDate.getTimeInMillis());
Date dueDate = new Date(Code.DueDate.getTimeInMillis());
if (Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis()){
AlertDialog.Builder myDialogBattery = new AlertDialog.Builder(
Assignment_Create.this);
myDialogBattery.setTitle("How to use Less Battery");
myDialogBattery.setMessage("hahahahahaha");
myDialogBattery.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
}
});
myDialogBattery.show();
}else
{
if (isEdit) {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.update(updateId);
this.dataManipulator.close();
} else {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.insert(Code.title, Code.description,
Code.strDays);
this.dataManipulator.close();
}
Toast.makeText(getApplicationContext(),
"Details are saved successfully", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(),
"Assignment Created Succesfully", Toast.LENGTH_LONG).show();
Assignment_Create.this.finish();
}
break;
}
}
try following code. Here firstDate and secondDate are Date object
if (firstDate.after(secondDate)) { OR //secondDate.before(firstDate)
//display alert here
} else {
}
I am using a DatePicker so that the user can select a date and find out the sunrise and sunset times for that particular date.
The webservice I am using requires the date to be snet in the following format dd/MM but I would like the button to show the date in the format DDth MMMM YYYY e.g 21st March 2013

Your help would be greatly appreciated.
Please ask questions for clarification if need =)
----------------UPDATE-------------------------
I'm getting there, updated code now looks like this:
public void showDialog() {
FragmentTransaction ft = getFragmentManager().beginTransaction(); //get the fragment
frag = DateDialogFragment.newInstance(this, new DateDialogFragmentListener(){
public void updateChangedDate(int year, int month, int day){
DateFormat format = new SimpleDateFormat("DD MM yyyy"); // could be created elsewhere
now.set(year, month, day);
date.setText(format.format(now.getTime()));
date.setText(String.valueOf(day)+"-"+String.valueOf(month+1)+"-"+String.valueOf(year));
now.set(year, month, day);
}
}, now);
frag.show(ft, "DateDialogFragment"); }
Just use another SimpleDateFormat to format it.
public void updateChangedDate(int year, int month, int day) {
DateFormat format = new SimpleDateFormat("DD MM YYYY"); // could be created elsewhere
now.set(year, month, day);
date.setText(format.format(now.getTime());
}
Unfortunately there is nothing provided by Java to automatically get the proper suffix for ordinal dates (2nd, 13*th*, 21st, etc.)
public void showDialog() {
FragmentTransaction ft = getFragmentManager().beginTransaction(); //get the fragment
frag = DateDialogFragment.newInstance(this, new DateDialogFragmentListener(){
public void updateChangedDate(int year, int month, int day){
now.set(year, month, day);
date.setText(DateFormat.format("dd MMMM yyyy", now));
}
}, now);
frag.show(ft, "DateDialogFragment"); }
Change
date.setText(String.valueOf(now.get(Calendar.DAY_OF_MONTH)+1)+"-"+String.valueOf(now.get(Calendar.MONTH))+"-"+String.valueOf(now.get(Calendar.YEAR)));
to
date.setText(DateFormat.format("dd MMMM yyyy", Calendar.getInstance()));
public void showDialog()
{
FragmentTransaction ft = getFragmentManager().beginTransaction(); //get the fragment
frag = DateDialogFragment.newInstance(this, new DateDialogFragmentListener()
{
public void updateChangedDate(int year, int month, int day)
{
String dateFormate = "dd'" + getDayOfMonthSuffix(day) +"' MM yyyy";
DateFormat format = new SimpleDateFormat(dateFormate); // could be created elsewhere
now.set(year, month, day);
date.setText(format.format(now.getTime()));
now.set(year, month, day);
}
}, now);
frag.show(ft, "DateDialogFragment");
}
String getDayOfMonthSuffix(final int n) {
checkArgument(n >= 1 && n <= 31), "illegal day of month: " + n);
if (n >= 11 && n <= 13) {
return "th";
}
switch (n % 10) {
case 1: return "st";
case 2: return "nd";
case 3: return "rd";
default: return "th";
}
}
I copy above getDayOfMonthSuffix function from the below link
