What Set current date as default date and i want to allow user 15 days behind from current date not below than that date.Please help to resolve this.

DatePickerDialog is a Dialog But DatePickerDialog.OnDateSetListener is not a Dailog that can be cast. So show DatePickerDialog instead of showing datePickerListener. It's the line of error
((Dialog) datePickerListener).show();
See the example how DatePickerDialog is created and used.

//Current date
String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
// editText is the EditText that should display it
editText.setText(currentDateTimeString);
For 15 days limit, you can use if else condition before setting the date to edit text.So if user Selects date before 15 days the edit text remains empty

There are couple of errors that I've noticed in the code,
1) Replace
calIcon.setOnClickListener(new Button.OnClickListener()
with
calIcon.setOnClickListener(new View.OnClickListener()
2) Below type-casting is causing the crash
((Dialog) datePickerListener).show();
You should create an instance of Dialog, build it with require attributes and set the listener. Then call the show() method on it. Refer, Datepicker: How to popup datepicker when click on button and store value in variable

Data exchange via Intent between Fragments works on pre-5.0 but not on Android 5.0

As a part of The Big Nerd Ranch's Android Guide example Criminal Intent,
I am updating a button with date/time entered in the
Date/TimePicker. Button and Date/TimePicker reside in different
fragments. I am transferring data between them using an Intent. It
works fine on Pre-Lollipop devices but doesn't seem to update button
text on Android 5.0 or Lollipop devices. What am I missing?

The problem isn't with the communication between the Fragments, it's that for some reason the default CalendarView DatePicker in Lollipop never calls the OnDateChanged() method, so mDate in DatePickerFragment.java never gets changed; DatePickerFragment sends back to CrimeFragment the same value it received from CrimeFragment, so it only looks like the communication between the two Fragments isn't working.
The Lollipop DatePicker does call OnDateChanged() when it's in SpinnerView mode, so CrimeFragment's date will then get properly updated. Unfortunately, Lollipop ignores the android:calendarViewShown="false" directive in the DatePicker's tag in the dialog_date.xml file. The only way to force the DatePicker to display as spinners is to include a android:datePickerMode="spinner" directive in the DatePicker's xml tag. You will get a warning that this directive is supported in API 21 only, but it will be ignored by devices running pre-5.0 Android.You have to keep the calendarViewShown="false" directive for pre-5.0 devices.
DatePickerDialog appears to have been fixed in Android 5.0, so you could also use that resource in DatePickerFragment to make things work.

DialogFragment does not update the Display

I am new to android development and I hope you can help me solve my problem. Any help will be appreciated. I created a dialogfragment for picking dates. I am able to select the desired dates but I am having trouble in displaying the selected dates.
Here is my DialogFragment
public class DatePickerFragment extends DialogFragment implements
DatePickerDialog.OnDateSetListener {
private Calendar mCalendar;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
mCalendar = Calendar.getInstance();
int year = mCalendar.get(Calendar.YEAR);
int monthOfYear = mCalendar.get(Calendar.MONTH);
int dayOfMonth = mCalendar.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, monthOfYear, dayOfMonth);
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mCalendar.set(Calendar.YEAR, year);
mCalendar.set(Calendar.MONTH, monthOfYear);
mCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
}
and I call it from my remindersFragment which extends fragment
private void registerButtonListenersAndSetDefaultText() {
mDateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//getActivity().showDialog(DATE_PICKER_DIALOG);
android.support.v4.app.DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getFragmentManager(), "datePicker");
updateDateButtonText();
}
});
updateDateButtonText();
}
and my updateButton :
private void updateDateButtonText() {
// Set the date button text based upon the value from the database
SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_FORMAT);
String dateForButton = dateFormat.format(mCalendar.getTime());
mDateButton.setText(dateForButton);
}

Getting data from a DatePickerDialog to a fragment

As above I am trying to work out how to pass back the date selected by the user. I have worked out how to get the date selected by using the onDateSet method but I do not know how to feed this back to the parent fragment, and then set the EditText text to the date selected.

In Your Fragment

edittext.setOnClickListener(dateListener);

on tab change in same page, 2nd time OnCreate() doesn't work

All the functions are running properly, but only one problem exists that if i record details for a day, and if I switch tab to the history tab to see the new record, the viewlist in the history class should display that record. However the viewlist doesnot display the lastest record, and i check the database, the lastest record has been written into database. The only way to see the new record is to close the emulator and restart it.
I found the problem that on startup, the recorder and history tab would both be initialised in OnCreate() method. But after that when I switch between these two tabs, it would not be initialised. Therefore, in the history.class, it would not open the database and read the data. That's the problem. Could somebody please help me, thanks
