Invalid Hijrah Day of Month : 31

I tried to create a simple activity with a button and a textview that showing the date. The button should show the HijriDatePicker dialog when clicked. I tried to make it using ummalqura-calendar and by the dialog, i tried use the HijriDatePicker to create the dialog.
However, after many attempts, it doesn't work. Sometimes the activity will stop when I click the button, and sometimes it just crash. I tried already for many fail attempts.

This problem seems to be a known bug in the msarhan-library. There was also a meanwhile closed issue on its related website. It indicates that a fix has been applied in the newest version.
So I suggest you to update your marhan library to version v2.0.2 which might solve your problem.
Update:
When looking at the date-picker-library you use we can see that it still uses the version v2.0.1. Either you wait until the author of the date-picker-library fixes the dependency or you build your own version of the date-picker-library.

If you use koltin this method will fix your issue
fun selectDateOfBirthHijri(context: Context, editText: EditText, childFragmentManager: FragmentManager) {
val now = Calendar.getInstance()
val dateOfBirthClickListener =
HijriDatePickerDialog.OnDateSetListener { view, year, month, dayOfMonth ->
now.set(Calendar.YEAR, year)
now.set(Calendar.MONTH, month)
now.set(Calendar.DAY_OF_MONTH, dayOfMonth)
editText.setText(
Formatter.format(
now.time.toString(),
Formatter.EEE_MMM_DD_HH_MM_SS_ZZZ_YYYY,
Formatter.DD_MM_YYYY
)
)
}
val ummAlquraCalendar = UmmalquraCalendar()
val b = HijriDatePickerDialog.newInstance(
dateOfBirthClickListener,
ummAlquraCalendar.get(UmmalquraCalendar.YEAR),
ummAlquraCalendar.get(UmmalquraCalendar.MONTH),
ummAlquraCalendar.get(UmmalquraCalendar.DAY_OF_MONTH)
)
b.maxDate = UmmalquraCalendar(ummAlquraCalendar.get(Calendar.YEAR),
ummAlquraCalendar.get(Calendar.MONTH),
ummAlquraCalendar.get(Calendar.DAY_OF_MONTH))
b.setTitle(context.getString(R.string.hint_date_of_birth))
b.show(childFragmentManager, "HijriDatePickerDialog")

FatalCrash when I click on a Button

I have this RemoteCar App which has the Buttons,
"LOCK" -> leads you to another Acitivity.
"LOCATION" -> leads you to another Activity.
"START ENGINE" -> Lets you click on it and it changes the txt into
"ENGINE RUNNING".
"REFUEL" -> lets you refuel and increments my ProgressBar(FuelBar).
So the problem I have is that I can't click on START ENGINE or REFUEL anymore since the App keeps crashing for reasons I can not resolve, yet. I can easily click on LOCATION and LOCK those work perfectly fine.
Here I have the ErrorMessage:

Attempt to invoke virtual method when displaying TOAST? [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 6 years ago.
when you click a button in my activity it starts/displays a DatePickerDialog. When the user selects a date and clicks "ok" i want to run an AsyncTask in the original class (the activity where the button was clicked). Everything works but i want to display to the user a TOAST when the AsyncTask is finished but it keep on getting an error when doing so.
Heres my code:
Button method in the BuyerHomePage.java
public void MeetingCreator(){
CalenderImageButton = (ImageButton)findViewById(R.id.CalenderImageButton);
CalenderImageButton.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment picker = new DatePickerFragment();
picker.show(getFragmentManager(), "datePicker");
}
}
);
}
DatePickerFragment.java code
public class DatePickerFragment extends DialogFragment
implements DatePickerDialog.OnDateSetListener {
public static String formattedDate;
#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);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
#Override
public void onDateSet(DatePicker view, int year, int month, int day) {
Calendar c = Calendar.getInstance();
c.set(year, month, day);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
formattedDate = sdf.format(c.getTime());
BuyerHomePage Meeting = new BuyerHomePage();
Meeting.new MeetingSender().execute();
}
}
BuyerHomePage.java (post method in the AsyncTask)
#Override
protected void onPostExecute (String result){
if (result.equals("email sent")) {
//This is where i get the error
Toast.makeText(BuyerHomePage.this, "Email sent!", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(BuyerHomePage.this, "Can't send email", Toast.LENGTH_LONG).show();
}
}

I am calling dueDate.setText() however it is returning null. I called view.getRootView() because I am inside the view of DatePicker therefore it should return the view containing my dueDate TextView. I could also pass the View from the method calling DatePickerFragment but I do not know how.I am guessing that DatePicker view when called getRootView() does not return the view that contains R.id.dueDate. Thanks in advance.

Issues storing data into Parse - Using TextView

I have received the following unexpected error while trying to run my activity:
Invalid type for value: class android.widget.TextView
Essentially I am trying to store data into Parse.com, where a user would select their calendar date and time through button clicks, and where the date and time selected would be recorded and shown into two TextViews that is displayed to them (Date and Time). Now I want to grab the TextViews information and record it into parse.
Below is the logcat message:

If you require any additional information, or clarification, let me know.

currentUser.put("ActivityDate", txtDate);
currentUser.put("ActivityTime", txtTime);
Above two lines require ("key",value) pair.As you are passing only the TextView widget its causing exception.
Replace your line with these
currentUser.put("ActivityDate", txtDate.getText().toString());
currentUser.put("ActivityTime", txtTime.getText().toString());
EDIT
For Validation of your textView do this in your onclick method:
mConfirm2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(txtDate.getText().toString().length()>0 && txtTime.getText().toString().length() >0 ){
ParseUser currentUser = ParseUser.getCurrentUser();
// Create the class and the columns
currentUser.saveInBackground();
currentUser.put("ActivityDate", txtDate);
currentUser.put("ActivityTime", txtTime);
currentUser.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
setProgressBarIndeterminateVisibility(false);
if (e == null) {
// Success!
}
else {
}
}
});
}else{
Toast t = t.makeText(context,"Please fill all the details !",Toast.Length_LONG);
t.setGravity(Gravity.center,0,0);
t.show();
}
});
