Is it possible to switch the format of date picker header?

I am trying to change the header on material design date picker as you select a date to a different format than default. Current default is Month , year : ex: june 22, 2021, but I want it such that its Mon, June 22. It's shown on material design document as the first design, but there's no indication of how to go about changing this format?
Any ideas?
material designs : https://material.io/components/date-pickers
what I want to achieve is this :

Unfortunately, you can NOT change Date Format and Local of MaterialDatePicker.
Since MaterialDatePicker is very restricting, so as many other Material Design Components, I recommend you to use an alternate Date Picker Library such as MaterialDateTimePicker.
It basically fulfills all your needs:
Change date format: setLocale(Locale locale) ✅
Choose from multiple date UIs ✅
Very flexiable and easily customizlbe to fit your needs ✅
PS: There is one more popular alternative: android-betterpickers
Let me know if you have any other questions.

After looking into the source, and trying some things, I did find a solution. Unfortunately, it's not that simple to implement and I guess switching to MaterialDateTimePicker is still the best solution here.
The conversion from date to text for the header is done by the DateSelector via getSelectionDisplayString(Context context). See getHeaderText() inside of MaterialDatePicker here.
Sadly, MaterialDatePicker is final, so you can not simply create your own and override this method. But, with the given Builder, you can use MaterialDatePicker.Builder.customDatePicker(DateSelector selector) to place your own DateSelector (source).
Material uses their SingleDateSelector (source) for a simple date selection. But again, it's not possible to build upon this selector and write a custom getSelectionDisplayString method, because the class is restricted. Knowing this, it's needed to write your own DateSelector.
Building your own DateSelector is a bigger task on its own. It may be possible to copy from SingleDateSelector, but it's using some private classes and methods you need to copy, too.
To cut a long story short, I guess this is too much for "simply" changing the date format.

Is there an option to change Date Picker form?

I implemented date picker in my project from here: https://developer.android.com/guide/topics/ui/controls/pickers
The problem is, this date picker is in the format of regular calendar, and it takes a long time to choose faraway dates. In my app this kind of action is going to be performed all the time.
So, my question is, is there a possibility to change this calendar-like form to something faster? For example like in the picture below.
Picture of date picker i would like to make

check that library: https://github.com/florent37/SingleDateAndTimePicker
I've used it some time ago and it did almost exactly what you're looking for ;)
If it doesn't fit your needs, you can look for more 'iOS style date pickers' for Android, for example in this SO post:
ios like date/time picker for android platform
Edit:
It seems that this picker is Holo Light style and is achievable with this piece of code:
DatePickerDialog datepickerdialog = new DatePickerDialog(getActivity(),
AlertDialog.THEME_HOLO_LIGHT,this,year,month,day);
But you need to check that on your own because they might be deprecated or not working with other themes.

Did you check this for Material Design?
Here is its documentation and code.

The DatePicker widget in Android has an attribute called android:datePickerMode that has a calendar option and a spinner option.
You can use the spinner option to get the appearance of the DatePicker you are after.

Change the style of Android Calendar View

I am using a calendar view inside a dialog fragment .I am getting the one as shown below. I am using the default calendarview provided.
But instead i want to get a calendar view as this one , which is shown by default in xml when i add:
I have tried changing the style to Widget.DeviceDefault.Light.CalendarView , Widget.Material.CalendarView but with same effect.

I don't know How to create Custom Calendar but you might check this GitHub library.You may succeed in creating the one, you are asking for with just little customization
https://github.com/prolificinteractive/material-calendarview
And also Refer to this Useful Stackoverflow post from which you will definitely be able to implement a CalenderView as you wanted.
Custom Android calendarView

At first I didn't understand why CalendarView component looks different in Android Studio and on my phone, but then I found this post https://stackoverflow.com/a/45368436/11052714
So the reason you are seeing this on your phone is because of API level. In the post I mentioned above, however I think wrong API level is mentioned, because I have the old calendar view with Android version 5.0.2 aka API level 21. It means that still in API level 21 old Calendar View visual look is used.

Android timepicker - similar to this in the Alarms app

In the android alarms app I have a dialog datepicker that has a keypad (image attached):
is that a standard timepicker? because I couldn't find how to do it. I found the TimePickerDialog - but that is no a keypad.
Is there a property that I'm missing or a library that does that kind of timepicker dialog?
Thanks

see this answer i have already given for this type of pickers :)
Implementing New styled date&time-pickers from android

How can i change Timpicker Style wheel?

How can I change Timepicker Style to whee?
When I make Timepicker in my layout
like this
but I want this style
i know that is default style. I don't know how I can change the timepicker style
what can I do?

That is because you use old api (lower than ICS 4.0). To use the new styled TimePicker import SimonVT's TimePicker library. It has exactly the same style, that android > 4.0 TimerPicker has. It can be used starting from Android 2.1.

Use wheel picker library. You can style it any way you like and there is no limit to the type of content you can put in it. It's written by a Google Developer and I've used it in the past with no issues. I think it's compatible for Android 2.1+.
