Hei Arif! Try changing the playback speed by clicking on the three dots on the top right corner to 0.5x.

Thanks 😊

@@CodeWithCal 😊 welcome Sir 👐🏻

The highlighting part should be easy enough. How would you go about importing Holidays? Would it be user input? Or are you thinking of pulling from web service?

@@CodeWithCal pulling from webservice and what if want to highlight present date ? Thank you for you time and consideration.

Notifications tutorial, can go on the to do list, thanks.

🙏

Thanks 😊

The only reason I choose a higher target. Is for the use of Localdate, if you need to target lower I see no reason it shouldn't work you'll just have to rewrite out local dates for dates.

Have you seen the weekly calendar tutorial? We highlight selected date in that and you could apply that to the monthly calendar. kzfaq.info/get/bejne/odSghsWlx7beY6M.html

06:35 in Weekly calendar tutorial

@@CodeWithCal thanks a lot.. I will try to highlight the current day...

I'm not sure I understand what you mean?

@@CodeWithCal Hi, bro! fine? I solved my question.. follow the solution: //before inserting the array into adapter if(firstDayOfMonth==7){ // remove all the empty elements from the beginning of the array when the first day of the month is on sunday. while(daysInMonthArray.get(0).isEmpty()){ daysInMonthArray.remove(0); } } // remove all the empty elements from the end of the array. while(daysInMonthArray.get(daysInMonthArray.size()-1).isEmpty()){ daysInMonthArray.remove(daysInMonthArray.size()-1); }

A follow up Weekly Android tutorial is in the making. :) I'm not using content resolver how ever...

Absolutely possible. 06:46 try to really understand what we are doing here with our days in month array. And I think the answer will become apparent. I would probably change the array to hold dates intead of strings and when we loop through the 42 days save each date, then in the calendar view holder check to see if the date is either the next or previous months and if so maybe change the text color or something.

@@CodeWithCal I tried whatever you said to me yesterday...but in ArrayList i got extra days for PREVIOUS and NEXT months.. can you please help me out and if possible please share code regarding this..

@@CodeWithCal done bro see yr weekly calendar code & solve my bugs tq dude

Hard one to troubleshoot with out seeing the layout myself. Try nesting the original layout inside your new relative layout

Absolutely! Worth doing properly have a read of the following developer.android.com/training/basics/supporting-devices/languages

kzfaq.info/get/bejne/d8-XbJylks2yoYE.html&ab_channel=CodeWithCal 09:32 - Monthly Calendar (Prev & Next Months Greyed out) You can do a similar thing as to here, where you compare current date to date and if so change bg color or something

Hey Lurg, The on ItemListener is an interface, have you added this line public class MainActivity extends AppCompatActivity implements CalendarAdapter.OnItemListener

@@CodeWithCal I try to Integrate the Calendar in my App. So its not my MainActivity but that shouldn't be a problem, right ? First I thought its because my MainActivity was a Fragment but I also tried it with an new Activity with the same problem

In the adapter add an if statement to check if the date is todays date. if so change the bg color or something similar

@@CodeWithCal But how to do that? This solution does it for the same day in other months too

Hard to say without seeing the code. Break points are a great debugging tool.

After setting the dayOfWeek variable create an if statement before the for loop to see if it equals 7. If it does set it to 0. if (dayOfWeek == 7) { dayOfWeek = 0 } There is probably a better way, but this worked for me

​@@AimesX8 where would you write this? In the for loop?

I think you can do something along the lines of setlocale stackoverflow.com/questions/35581921/localdate-format-with-locale

I mean you probably could use the widget... Only you know the requirements of what you are trying to build. Benefit of the calendar in this tutorial is that it very customisable.

@@CodeWithCal I will create my own calendar. I think its easier to work with because i know how to access everything

I think the tutorial would be too similar. Thanks for watching :) good luck at uni

have you tried it on kotlin? I really need help as well I tried converting all into kotlin however, it wont open:((

@ChrisPugsworth Wasn't sure if you solved this yet, but I'm doing a similar section inside fragments. Mine seems to be working but only once you click one of the buttons and not upon creating the fragment (fixing that now). My setMonthView looks like monthYearText.setText(monthYearFromDate(selectedDate)); ArrayList daysInMonth = daysInMonthArray(selectedDate); CalendarAdapter calendarAdapter = new CalendarAdapter(daysInMonth, this); RecyclerView.LayoutManager layoutManager = new GridLayoutManager(v.findViewById(R.id.calendarRecyclerView).getContext(), 7); calendarRecyclerView.setLayoutManager(layoutManager); calendarRecyclerView.setAdapter(calendarAdapter); For myself I did have an issue where my RecyclerView simply wasn't partitioned to show correctly and wasn't visible so I would start there next if it still doesn't work. Hope this helps!

Yeah, I have gotten a bit carried away with the pace on a few videos. Like everything I'm still working on finding that balance. That's for the feedback. 😊

​@@CodeWithCal ​ Of course, you could try to go with something like Dani Krossing was doing, slow talk explaining the basics, if that is what you are aiming for of course. People will watch an hour-long video if they feel they are in control and understand what is going on. Other than that, great video. ;)

I'll check out some of his videos, cheers :)

Absolutely possible. I have a video on a more standard recycler view see link. You should be able to apply the on item click listener from the recycler view tutorial to the calendar view. :) kzfaq.info/get/bejne/f9xnediYyqnJoZs.html

@@CodeWithCal may i ask under what method and java file do i implement this on item click listener should it be in calenderViewHolder?

From memory that's correct the view holder implements view on click listener.

🎉

kzfaq.info/get/bejne/g7ilgsaDzKuUnYE.html Sounds like a good plan see link to custom spinner tutorial.

@@CodeWithCal thank you cal. Can you please make a tutorial on that or can you give hint how to do it...

​@@alokeshnath4269With the custom spinner tutorial you have the tools you need. You need 2 spinners a month and year. Create an array list of years and a list of months id probably just manually create them. Then pass them into your custom spinner adapter. You should be able to use the same adapter for both

@@CodeWithCal I have created two spinners that is month and year. Now the question is how to change month and year dynamically in the calendar that you have shown in this tutorial. Please Help me...

Did you get any help?

Have you resolved this? what error are you getting?

🙏

@@CodeWithCal u have tutorial for calender with event?

@@jeremyheng8573 kzfaq.info/get/bejne/odSghsWlx7beY6M.html

@@CodeWithCal got it! 1 more question is do you know how to create swipe-able month view?

@@jeremyheng8573 I do have an idea but it's probably a bit to complicated for a KZfaq comment. The tricky thing will be ignoring the recylerviews default on tap and swipe

Do you mean creating an event? A tutorial extending this one is on the to do list. But in the mean time. You can put a list view or a recycler view inside our calendar recycler view cell. (For list of events) And implement an on on item click listener per calendar cell to create a new event.

Hi, I would change the daysofMonth Array to hold the dates as apposed to the string of the day of month. Then inside the adapter you can check to see if what day of the week it is you will also have to extract the day of month. Finally change the colors accordingly.

@@CodeWithCal okay... Thanks a lot for answering

Hello, I believe the textview is null, the find view by id is not matched with the id in your xml. Double check the ids match in xml and java.

Hey, i got the same problem and ive been looking for it for a while now, ive checked the ids in my xml and theyre matched with the java. just wondering if you fixed yours and if you could share it, thanks

hey so have you found any solution? i got the same problem too :/

I found a solution: execute initWidgets() and setMonthView() in the onStart() method instead of onCreate()

Have you inflated the calendar_cell.xml correctly? Sounds like something is not quite right there.

@@CodeWithCal I took a step back and took more lessons on Android Studio and Java and came back after a few months and I still don't understand why "view" keeps throwing an error for me but not for you in this video. right-clicking on 'view' gives the following suggestions "Create constructor" and "Remove 2nd parameter from constructor 'CalenderViewHolder' " However, If I remove the second variable as suggested (The "CalendarAdapter.OnItemListener onItemListener" part) "view" wont throw an error anymore BUT now I get "Variable 'onItemListener' might not have been initialized" in that constructor. very confused. Edit: My understanding is that I would need two variables to pass into the constructor requiring two variables but I am only passsing one variable named "view" and it wont accept that. Unless im missing something that I am not understanding?

@@jrod1577 i am having same problem with you....and i am writing this with kotlin

So in the Calendar Adapter you can add an if statement to. check if the day you are up too is today. basically the same thing we do here in the daily calendar tutorial. 09:32 - Monthly Calendar (Prev & Next Months Greyed out) kzfaq.info/get/bejne/d8-XbJylks2yoYE.html

@@CodeWithCal but how can I do this with single days saved in a SqLite Databank. Its not possible to load data because I cant pass a Context in the parameter from the Adapter class but I also can't pass an Arraylist from a different class with the Constructor because It says that its might not be initialized. What can I do ?

Looks like you've got your date formatter already sorted. or was that not the question?

Newer*

Yes, but Localdate class will not be available. No reason you couldn't rewrite all date functions to use java.util.Date instead of localdate :)

I don't see why not ☺️

Did you find a fix, sounds like you've got a few small mistakes

@@CodeWithCal Yeah, i got my bug fixed for the buttons taking the months back, so when I copied the button code to mirror it to the other side, I forgot to change the onclick listener to nextMonth... Yeah, it was me being a zombie. And as for the crashing when i click, i still didn't get it. Thanks a million for helping me learn Android App Development and also, a real big thanks to you cause I used to be a person who used to shy away from coding cause i thought it was Rocket Science, watching your tutorials really helped me get out of that head space and approach coding with an open mind. Thank you Big Time Cal!

@@KarnikDew Hi I was following this tutorial and I also have the problem where both arrows face backward. how exactly did you fix this bug?

You can add a conditional statement to the adapter.

Since Cal did it in Orea, if so may I know how?

You can absolutely! You just won't have access to LocalDates which have a lot of convenience methods. But you can use just a regular dates. your methods will need to be a bit longer as there is a little more logic you will have to be responsible for

🤔 interesting question. Depends. so many factors. Ultimately it does take some time to learn programming and android development. But I highly recommend to stick with it. I still only consider myself an intermediate at best, got to have the attitude that you are allways learning even after years of development :)

@@CodeWithCal Thanks Cal ;) sorry but Android Studio highlights the words Vertical & Horizontal in these lines in red! And I have just typed everything exactly like yours :) android:orientation="Vertical" android:orientation="Horizontal" You also still haven't really answered my question regarding how long will it take to be able to at least create an app that you can make money with? lol or at least for yourself? thx

​@@releNtless-eu3xc Could you have set the orientation twice? or is the parent definitely a Linear layout. These are just guesses as I cannot see your code. Well its true, I haven't answered your question as i feel it is an impossible one to answer. as there are just so many factors. I won't sugar coat, the app store is a very saturated market and to make money is tough... not impossible.. but tough. This is again maybe more philosophical of answer than you are looking for, but i believe there are no shortcuts in life and programming for that matter. Put in the time and effort and you will be rewarded eventually. Programming is a life long skill. that takes years to get good at. If you are only in it for the short term and for a quick dollar. I think you will be disappointed.

for some reason, I can't copy and paste my code in here!?

Also, I think I figured out myself what's the problem in here :) looks like there is nothing wrong with my code but for some reason although at the start of creating a new project I chose the template called with no activity for some reason my design view template doesn't show any textbox and I've even tried to insert one manually myself (textview or plain text) but looks like it inserts both of them outside that white rectangle and I'm not sure what I need to do in order to fix this problem?

Could be a few different things. Have you tried setting a break point in the adapter?

Wrap the whole thing in another view plus what ever view you need below it. I take it that's what you are trying to do?

@@CodeWithCal What I'm trying to do is have your calendar in LinearLayout in a ScrollView that have an another RecyclerView under the calendar where I can post events (cardViews), and I thought both RecyclerView can have wrap_content as height but I can't seem to figure it out because the recycleviews just doesn't show when the app is running

The recylerview will need some sort of fixed height im fairly sure.

@@CodeWithCal And what can use to add cardviews to and it's height is wrap content, I tried ListView but that did not work, any idea?

​@@leventestancz4522 Well a scroll view has ambiguous vertical height. So you need to add fixed heights to all nested views. Im not sure what you are talking about with the list view and card view. I thought I was helping with a layout issue 😂

Sure, what errors are you getting?

@@CodeWithCal i fixed the error. but now I need the whole code for the numbers in the calendar

Could be lots of things try adding a break point and reading the error message in your console :)

@@CodeWithCal There is no error. However, it is forced to shut down when you run the app. My code is the same as yours.

Hey Z, I haven't had much experience with fragments. But will try to help best I can. What exception are you getting?

Thank u for the reply Cal, my java compiles with no errors, when I run it, the app works, but the calendar fragment doesn’t respond. I tried looking at my logcat and build but there wasn’t an error pointing to my calendar-related classes. I am starting to think it has to do with the fact that it’s a fragment so I guess gotta debug line by line to.

@@mobius369 Anyone here a year later trying to solve this in fragments, the key is to remove the onCreate() method and put it in the onCreateView. View view = inflater.inflate(R.layout.fragment_calendar, container, false); then use calendarRecyclerView = view.findViewById(R.id.calendarRecyclerView); ect. I hope this helps. I got his code working with these tweeks. (you also need to fix the back and forward buttons.)

Can you make a tutorial pls...

I will put on the to do list :) Thanks for the suggestion.

Can I ask you how can I highlight the current date???

LocalDate.now() to get current date. Then you want to pass selected month and year into calendar adapter. Compare then if day month year matched change background color of view or what ever. Hope this helps.

I'm using androidx for this tutorial, perhaps you are targeting lower/older versions of android? developer.android.com/jetpack/androidx developer.android.com/jetpack/androidx/migrate

@@CodeWithCal Thank you! I continued the tutorial and found myself with the toast that doesn't appear. Do you know what causes this?

​@@dreadmanhua9552 Try double checking the context you pass to the toast. I know that has caught me out in the past

😅😉

Add pictures to each day in the month? That would be possible

@@CodeWithCal how?

​@@thesharonway4612 So first thing would be to add an Image View to the cell xml file. Inside CalendarViewHolder.java duplicate whats happening for: TextView dayOfMonth; so ImageView myImageView; etc.. As far as the CalendarAdapter maybe instead of passing in ArrayList daysOfMonth you could create a custom class with two fields dayOfMonth of type String and image resource ID (I'm pretty sure is an int) you can then pass in ArrayList daysOfMonth Hope this helps and good luck :)

@@CodeWithCal thank you

sorry. found the bug.

🥳

Sure thing, how can I help?

Happy to help, might need a bit more to go off. So you aren't getting any dates showing. does the recycler view have the correct number of squares?

@@CodeWithCal Yes, although all functions are working fine but the issues are with only dates

@@CodeWithCal I think the adapter is not attached properly

@@CodeWithCal Is it related to the minimum SDK version as I'm using min API level 21? Does this have something to do with it?

@@sawankumar6355 Yes, LocalDate class requires API 26. You could convert all local dates into java.util.Date. It will just take longer to write all methods and not have as many convenient things to call upon. Or up your min API

I provide a free tutorial, and you insult me by calling me a show off. Yeah this tutorial isn't perfect and maybe it is to fast, but you should be more considerate in the way you give feedback. Name calling is simply bullying and I won't stand for it.

😜

Yeah, feel the same. But I think we as the beginners are not the target audience. This tutorial shows how you could implement a calendar when you already got a hold on the basic kotlin and Android Studio functionalities. He doesn't explain anything related to the programming language. This is a tutorial of how to implement a calendar functionality, not a kotlin tutorial. We'll have to find that somewhere else and maybe someday this will be also useful to us too.
