Looking for the source code of the new Google Calendar Time and Date Picker Widgets

I would like to use the brand new Date Picker and Time Picker that is now part of the new official Google Calendar App.
http://googlesystem.blogspot.de/2013/05/new-google-calendar-controls-for-android.html
All I found so far is this source code on grepcode but I can't find the widgets or fragments or activities there.
http://grepcode.com/snapshot/repository.grepcode.com/java/ext/com.google.android/android-apps/4.2.2_r1/
Is that already public or is there something similar out there?

I think the code you are looking for can be found here:
https://android.googlesource.com/platform/frameworks/opt/datetimepicker/+/master/src/com/android/datetimepicker

There is some pretty directly usable source code snippets in this Android Developer Pages:
http://developer.android.com/guide/topics/ui/controls/pickers.html
I used it as-is and all works just fine.
Also, reference these:
DatePickerDialog
http://developer.android.com/reference/android/app/DatePickerDialog.html
TimePickerDialog
http://developer.android.com/reference/android/app/TimePickerDialog.html
DialogFragment
http://developer.android.com/reference/android/support/v4/app/DialogFragment.html

WindowManager.LayoutParams why is there a setTitle method?

So yesterday i was programming and suddenly i came across the setTitle method in the WindowManager.LayoutParams class, why would this class like this have a setTitle method? Where is is used for? The documentation does not say anything about the function.
My guess is that it could be used for debugging or something a like, but other than that i don't have a clue.
And why would it be declared as final method? Because it's not ready yet for us to override it?
Just wondering...
Note: Both answers below are some how "correct" and offer good information, but can only accept one.
getTitle
setTitle

Going through the source code for WindowManager, it seems that the title isn't actually used anywhere, except in the debug and parcel writing methods.
Furthermore, searching google for +"windowmanager.layoutparams" +".setTitle()" site:grepcode.com doesn't seem to return any results where the setTitle() and getTitle() methods of WindowManager.LayoutParams are actually used in production code.
I'd say that the Android engineers felt that maybe at some point of time in the future they might need a title property, and put it in as a stub.

Well There doen't seem to be any usage for this layout parameter value anywhere.
It seems like a place holder for now.
I only managed to find these tow cases where it has been used:
SoftInputWindow
and
StatusBar Service
And visually both has no effect (at least on my device and emulator)

How to make a DatePicker with DialogFragment and FragmentManager?

So I have been at this for a while, and I cannot seem to figure it out. I am fairly new at Android development, so bear with me please. I wasn't too familiar with creating a Datepicker and I learned to do it the deprecated way just to get the hang of it. Used this tutorial to get me up to speed:
http://developer.android.com/resources/tutorials/views/hello-datepicker.html
But now I need to change it, mainly to not use deprecated code, so I looked all around, and I found 2 tutorials, mainly this one though:
http://www.kylebeal.com/2011/11/android-datepickerdialog-and-the-dialogfragment/
Problem is, there is code that does not make sense. Mainly this part:
//create new DateDialogFragment
DateDialogFragment ddf = DateDialogFragment.newInstance(this, R.string.set_date, date);
ddf.setDateDialogFragmentListener(new DateDialogFragmentListener() {
#Override
public void dateDialogFragmentDateSet(Calendar date) {
// update the fragment
mDateDetailFragment.updateDate(date);
}
});
ddf.show(getSupportFragmentManager(), "date picker dialog fragment");
That is suppose to be what is running in the activity class that it runs in. So I kind of get whats happening throughout the rest of the code, and feel free to look at the rest as it will probably help. The code is essentially following almost the same route as the original showDialog() code. Implementing DatePickerDialog.onDateSetListener, and returning a new DatePickerDialog, with the obvious exception thats its using a DialogFragment. But that is where I have gotten lost.
Part of the reason is because I am not really sure where onCreateDialog() returns that new DatePickerDialog. If you look at the code I said does not make sense, both mDateDetailFragment and getSupportFragmentManager() were never instantiated or appeared anywhere else, so I cannot get the tutorial code to even work. The Android Doc also mentions that instead of using showDialog() I should be using both DialogFragment and FragmentManager, which is also not done here. Only DialogFragment.
So like the title, how exactly can I make a DatPicker in the non-depracted form? I would please ask to NOT send me to a link and just say look here. I have done that. Believe me. If not, at least explain what I have missed that makes this make sense. Also, if anyone can actually tell me where the onCreateDialog() method sends the DatePickerDialog, that would be extremely helpful as well. I am just trying to make sense of all this, rather than copy and paste code (not that it works anyways). Thanks a lot for taking the time out to read this, and if any clarifications needed, please ask.

Going in order of your post... \
1) the onCreateDialog returns the dialog to the DialogFragment.
2) I don't know about the mDateDetailFragment.updateDate(date); line... I think he might have left some code out. EDIT Found it, it's in one of the classes in the zip file for his complete demo.
3) You are using the fragment manager (it's the getSupportFragmentManager() part):
ddf.show(getSupportFragmentManager(), "date picker dialog fragment");
Ok, that said, here's how I've done it (I'm using a DateSlider, but subbing in a Datepicker in it's place should be simple enough for you).
In the fragment/activity calling the DialogFragment:
DialogFragment newFragment = new DateDialog();
newFragment.show(getFragmentManager(), "dialog");
And my DialogFragment:
public class DateDialog extends DialogFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
private DateSlider.OnDateSetListener mDateSetListener = new DateSlider.OnDateSetListener() {
public void onDateSet(DateSlider view, Calendar selectedDate) {
MemberAddFragment.startTxt.setText(String.format("%tB %te, %tY", selectedDate, selectedDate, selectedDate));
}
};
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance(); // Get calendar instance to use in DateSlider
return new AlternativeDateSlider(getActivity(),mDateSetListener,c,null,null); // return DateSlider dialog to DialogFragment
}
}
Hope this helps clear up your confusion.

I know this question is mine and already has an answer. But I thought I'd add my own answer to others looking for help on this same issue. I have simplified the example code that I provided above into only 2 classes. Kbeal, who was gracious enough to provide the tutorial did a great job, but it was too bloated with information that was not even necessary. So using what I knew about dialogs and what I learned from what I could understand from the Kbeal's tutorial as well as the research I did on fragments, I have provided my implementation from a DatePickerDialog on my GitHub.
https://github.com/Zeroe31890/DateDialogFragment
All you honestly have to do is run it straight after only copy and pasting the 2 classes, the single layout, and modifying the Android Manifest file. Much easier than any of the other tutorials. Oh and if anybody sees anything that can be done better on it please do. Enjoy!

Author of the post here: Sounds like you have it all figured out. I replied to your questions on my post before finding this though Barak does a fine job of answering them. If you haven't done so already download the complete source for the example app. I think it will help fill any missing blanks you still have.

Help with Android MonthDisplayHelper

How exactly do we use Android's MonthDisplayHelper? Ive been searching for possible widgets/views that would help me simplify my work as I would need to create a calendar. but it is just so hard. at least for me. So i saw this MonthDisplayHelper. from its members, i think i know what it can do..but what i don't get is how are we going to use it as i dont see it extending the view class nor is it an adapter. i know the question might be confusing. im heck confused right now. i hope somebody could help.
enlighten the confused :D

im sorry this came late..i have figured it out myself that MonthDisplayHelper will not make a Calendar for me. Well i hope it did. Creating a calendar functionality is not an easy task. we are faced with relatively complex algorithm.
so MonthDispalyHelper, again, will not make a calendar for you. Rather, it provides utility functionalities that would help you build your own calendar. a very good example of that is
MonthDisplayHelper mdh = new MonthDisplayHelper(viewedYear, viewedMonth);
int temp[] = mdh.getDigitsForRow(countRows);
which basically gives us as an integer array representation of which dates(digits) should go to each cell of the calendar. say for example, the first rows of the calendar of the supplied month and year(July 2011), would be {26,27,28,29,30,1,2}. from there, the job to position those digits to your layouts would be yours.
it also provides methods such as getting the number of days that the month specified have, the day of the week that the month starts, among other things.
i hope this helps.

This project uses MonthDisplayHelper, which might help understand how it works.

How to customize a TimePickerDialog?

I'm looking to create something EXACTLY like TimePickerDialog (look and feel) in Android, but it would be for MINUTES/SECONDS, not HOURS/MINUTES. Therefore AM/PM would not be relevant and would therefore allow MINUTE to be greater than 24 (making the max 59).
Is it possible to change the TimePickerDialog instance in any way to reflect this?
Any and all suggestions would be greatly appreciated. :-)

Is it possible to change the TimePickerDialog instance in any way to reflect this?
No, but the layout and source code to TimePickerDialog are both available as a starting point for implementing your own dialog.

This might help:
TimePicker with seconds:
https://github.com/IvanKovac/TimePickerWithSeconds
Have a look.

As the links in CommonsWare's answer are now dead, you might want to know that the source for TimePickerDialog is probably already on your local machine - it is included in the SDK. Try looking in the following locations:
[SDK_HOME]/sources/android-23/android/app/TimePickerDialog.java
or
[SDK_HOME]/sources/android-23/com/android/datetimepicker/time/TimePickerDialog.java
[SDK_HOME]/platforms/android-23/data/res/layout/time_picker_dialog.xml
Of course, choose the Android version that you want to borrow from. References to R. should be to android.R. Unfortunately, there seem to be some visibility issues with ValidationCallback - even on recent SDK levels.
