Mitch, I have a degree in mobile app development. I wish I would have seen this while in school. It helped a lot and will continue to help a bunch. Thank you for all you do.
Superb...i searched every where but all were directing to onBind Holder...and that was very confusing for me,,, but your method is very very easy...and it solved all my problem...love you for this helpful guide....
Ohh Glad to see you here. You both are Best. Please guide me on this issue. I try to resolve this issue from last two weeks but not getting solution yet. How can I change the View which is previously clicked in RecyclerView. I have a play button in every single row of RecyclerView. Whenever this button is clicked button visibility changed like shown in this image imgur.com/0fpk0Jv. When user click on first row button visibility changed which is working fine. But when user click on second row button of RecyclerView I want to change the button of first row to came back to its original position. Scenario shown in this image imgur.com/n4Q26Qm
Thank you so much. I've got a huge project rn and the only thing that was troubling me is communication between the recycler view and the Activity that uses it. Thank you so much! It fixed my issue
Hey Mitch, just wanted to say I was stuck on a problem for a long time and your video (especially the part where you took us back and walked through everything we did) was super helpful. I was able to resolve my problem after re-approaching it with a clear head. Thanks for the guidance!
Mitch, I definitely appreciate your content. Software/firmware development is nothing new to me, but I recently got into app development, and this series has helped tremendously! I was having difficulty with changing the TextView text color within my ViewHolders in the RecyclerView, but was eventually able to figure it out with your interface examples on the Note RecyclerView series. Thank you so much.
Had to come back to this video to say how much I appreciate what you do, I have used this in my recyclerView app a long time ago and now I was looking for a way to fix a similar issue in different java swing application where I used the same concept with an interface and it works as a charm. Man you really have no competition when it comes to this stuff. Wish you pleasant holidays mate, you deserve it
2021 ik but thx alot dude, you fixed my crahing issues. I have my holder class separated from my adapter class so every time I clicked one of my items it crashed but not anymore, ur the best.
Thank YOU!!!! I changed it a little to apply to a fragment but after hours of finding shite tutorials it's finally working! I'll put your name on my bachelors degree LOL
Thank you Mitch! I finally be able to go to another different activity for each item clicked! Implemented the switch case in the onNoteClick and it worked! :)))) p/s: I used the coding from your previous recyclerview and edited from there.
Thanks mitch, the other tutorial on another guy on how to setup a recyclerview had miss one thing on how to implement the listener to get clickevents, he forgot to add view.setonclicklistener(this); on the customviewholder. thanks again!
Hi, first I'd like to thank you for your videos and lessons, and then I got two questions that I hope you have time to answer. 1. How to make each item to open a new activity (not the same) example item (A) opens activity (A) and item (B) opens activity (B) and so on. 2. How to implement onBackPressed() or finish() method in the clickListener method of recyclerView, for example if item (A) clicked open activity (A) and finish its current activity. Thank you again.
I know the video's a couple of years old but I just really need to say that this was a great video/explanation, thank you so much, helped out a lot, pura vida 🙌
I learned multiple new things today, this first being that you can actually implement multiple interfaces in a class declaration. I couldn't figure out how to get this to work (I'm using a cursor and SQLite db), but it turns out you can implement multiple interfaces by separating with commas. Class Xyz implements Manager.Cursor, Adapter.Listener { Ha! Thanks for the video, super helpful!
On another note, you should try using the room persistence library instead of the old "cursor" way with SQlite. I have a free course if you're interested. codingwithmitch.com/courses/sqlite-room-persistence-android/
@@codingwithmitch Thanks yeah I'll definitely try that out. It seems like a constant struggle finding what's been deprecated and what is still like 5 years old but still heavily used. I realized a little late into my project that (apparently) the Cursor is dead.
That's great, dude! When I was finding on Russian chanels this info, I didn't do that, but when I saw your video, I understand that no metter what I need, I have to search everything on English chanels at ones!
Finally helped me get my code up and running, migrating everything from Java to Kotlin was pretty seamless but the Adapter definitely gave me a couple migraines. Thanks!
Thank you sooooooooo much for your super kind explanation!! I found it so easy to follow. I've actually tried several ways to apply OnClickListener to recycler items but I had failed to come here! I'll keep subscribing for additional help! >ㅁ
Hi would you handle items inside the recyclerview click listener. For example, lets say there is a checkbox inside the recyclerview and you want to handle the click event .
Hi! What's the best practice to do the same in Kotlin? I'm trying to solve an issue in my app with a RecyclerView in a fragment with the Search filtering and conditional clicking (if the item has a field equals "something", its click navigate to another fragment, else show a Snackbar)...I put the OnClickListeners inside the OnBindViewHolder and everything works fine till I search for a specific item in list: if I filter the results obtaining a "navigationable" item, if I click on it all it's ok; if I continue the search, filtering by the one with Snackbar, and I click on it, all it's ok. But If I reset my SearchView, making all the entire list appear again, and I click on the first item, that allowed me the navigation at the beginning, it will show me the Snackbar with the message belonging to the last item that I previously filtered that didn't allow me the navigation. It seems to me that the last OnClickListener, obtained in the search, overrides the previous one and bbrakes the algorithm functionality, or something like this. Hope I explained more or less my issue. THANK YOU IN ADVANCE!
Can i ask sir? how about when i try using firebase onclick listener on adapter. how can i make it like that? because when i try to make constructor i got an error that i should use ValueEvenListener than OnClickListener and i got an error too when i use the getAdapterPositions null pointer
Question. Now how can we do this in an application that uses MVVM architecture? and instead of an activity, lets use a fragment and initialize the recylerView and the adapter inside the Fragment?
@CodingWithMitch You have just mentioned performance issues but please give a detailed explanation of performance issues in the old method and how this method solves it ?.
Hey nice tips but whats the interface for ? Why not handle the click in the onClick method with getAdapterPostion if you don't need to change anything in the views ?
I can't do it I did everything as in the video it only works once when starting, after which it stops responding. It's probably because of the OnClickListener. Can it be because of the CardView that is in a different layout?
Activity is passed by (this) to adapter to create listener. So adapter has activity reference. But what's the difference to pass activity by reference and call method or field directly?
hey mitch, can you give me some advice about parent-child recyclerview? example on parent-Recyclerview i have list country (USA) and when im click the item, passing to child-recyclerview list name of city (New York, LA, Las Vegas, etc)
the new activity is not opening on clicking a particular item once. I have to click it several random number of times after which the intent works. And this is happening with all the items. Please help
when using recyleview in fragment, my constructor is itemByConveyanceIdAdapter = new ItemByConveyanceIdAdapter(context,items,this) , this getting wrong . suggestion to Change 3rd parameter of method 'ItemByConveyanceIdAdapter' from 'OnNoteListener' to 'Callback'
Do you have any tips for navigate from one fragment to another fragment? Some context so that you can beter understand my problem I am currently building a pokedex, I have fragment with a recyclerView where all the pokemons are shown. Now I want to make a fragment where you can see the details for a specific pokemon. But when i try your method i can't base the pokedex fragment to the adapter class. Do you have any tips or something i should look up?
Great tutorial!! I have a question and I wanted to implement that on my project, how will you put a custom back button on new detail activity so that whenever a user press on custom back button then it goes back to recycler view list items. ..? Can you please help me with that?
I have a question I hope is not too late. Making whole activities to implement a listener, is it good practice? is less expensive than creating a new class file for each specialized listener?
I understand how you would intent but how would you intent if each recycler holder should intent to different things. I tried an if statement with posistion value but that didnt work for me
Good explanation. I find it at times difficult to see, what good practices are with anroid components. The official documentation tends to give examples that are simple to understand, but are frequently adviced against. e.g. in the case of making api call on the main thread.
Great thing. But if I get the callback to a fragment and try to get the activity (getActivity() ) I get a null pointer error)... so how can get this after the callback you did? Thx in advance
I love this best practice video! By the way, does this also apply to the onClick method of onSwipe from ItemTouchHelper? I made a separate utility java files that extends ItemTouchHelper.SimpleCallBack. Should I also execute the commands inside this onClick, in the Activity class instead? Thanks so much in advance!
Dude...I was stuck on filtering one recyclerview from another for 3 days, then I implemented my onclick listeners like this, and now it works! thank you so much for this. Where can we find this by the way, is this on the documentation? Just know that you have saved my sanity xD
My itemclicklistener interface doesnt work when I change the dataset with notifydatasetchanged()?, also my notifydatasetchanged() doesnt work when i put everything on oncreateview in my fragment where I have my recyclerview, but my interface works. by what I mean by that is i am using buttons to categorize my items in recyclerview, but they don't work since on oncreateview i already have items query'd for all, but when i take that away and my buttons work, but my listener doesnt trigger when i click my items
So I have my recyclerview positioned inside of a fragment and want to make it so any image I press inside of my recyclerview is highlighted / selected when i do so. How do I acheive this? I have the debug window which states "Image n" pressed correcly when I click on an image, I'm just a little lost as to how I can get a handle on the imageviews from here.
Coding with Mitch & Coding in Flow are the 2 best tutors on TH-cam.
Mitch, I have a degree in mobile app development. I wish I would have seen this while in school. It helped a lot and will continue to help a bunch. Thank you for all you do.
5:36 the this keyword doesn't work for me. It provides ValueEventListener instead of OnNoteListener. Do you know how I can solve this problem?
i have a project due in 3 days and your channel is saving my life!! thank you so much for this!!! never clicked on subscribe this fast!!!
Superb...i searched every where but all were directing to onBind Holder...and that was very confusing for me,,, but your method is very very easy...and it solved all my problem...love you for this helpful guide....
Wow you must be a programmer or something
😏
Coding in Flow approves 😃
funny :)
Ohh Glad to see you here. You both are Best.

Omg I have learned more in this video than searching through a thousand forums, thank you very much
Tried to get a recyclerview click listener working for hours - this tutorial finally cracked it - Thank you!
Thank you so much. I've got a huge project rn and the only thing that was troubling me is communication between the recycler view and the Activity that uses it. Thank you so much! It fixed my issue

Explaining what you code was doing as you typed, and at the end to summarized really helped!! Awesome tutorial!!
Thanks a lot ❤️
This method is called inter fragment communication and we use it when we want our fragment to communicate with the activity...
Had to come back to this video to say how much I appreciate what you do,
I have used this in my recyclerView app a long time ago and now I was looking for a way to fix a similar issue in different java swing application where I used the same concept with an interface and it works as a charm. Man you really have no competition when it comes to this stuff.
Wish you pleasant holidays mate, you deserve it
I went to StackOverflow, couldn't find the solution. Then I found this. Worked like a charm. Thanks a lot
I am very happy to find your content. Excellent explanation, I have signed up for the full course on your website. Thank you!
Thank you for this..I was searching whole day for this..🙌
God bless you Mitch! It works like a charm!
2021 ik but thx alot dude, you fixed my crahing issues. I have my holder class separated from my adapter class so every time I clicked one of my items it crashed but not anymore, ur the best.
This was such a god sent....Thank you for uploading this. Such an elegant solution.
This is gold among so much shitty stack answers i found. Much thanks for this explanation and BRILLIANT revision at the end.
Thank YOU!!!! I changed it a little to apply to a fragment but after hours of finding shite tutorials it's finally working! I'll put your name on my bachelors degree LOL
Did you find a way to
Go from one fragment to
Another fragment
And then to show the id that was passed through
Hey Mitch. I have an error at 5:41. I already passed getApplicationContext and some other variables in the initialisation of Recycler adapter.
Hey Mitch thank your for this !!!
I appreciate the relay.
Thank you Mitch! I finally be able to go to another different activity for each item clicked! Implemented the switch case in the onNoteClick and it worked! :)))) p/s: I used the coding from your previous recyclerview and edited from there.
But only for the toast message, i don't know where to put the coding. But i guess it's okay as long as my goal is achieved 😂
Just fantastic! Finally someone who can break down a myriad of core topics into a one simple brain folder!!
Haha "brain folder". I like that
you're awesome dude. Really it is the Best Practice Way!!
My Issue was solved
Really appreciate the way you explain things .. made android easy for me ..
Thanks for help! Good quality example of create own listener and use it in RecyclerView.
Man you are the best, keep up you are saving the world.
Thanks mitch, the other tutorial on another guy on how to setup a recyclerview had miss one thing on how to implement the listener to get clickevents, he forgot to add
view.setonclicklistener(this);
on the customviewholder. thanks again!
Man i have been racking my brain trying to figure out why my click listener wasn't passing variables to a new activity. Thanks so much my dude.

Awesome Work Dude.
Really Appreciate it.
@CodingWithMitch
You have just mentioned performance issues but please give a detailed explanation of performance issues in the old method and how this method solves it ?.
Dude you are a LIFESAVER!!
Straight to the point!
Hello
I have question , if I want to add switch button in recyclerview item to disable or enable the item from click ,how can I do that please?
Hey nice tips but whats the interface for ? Why not handle the click in the onClick method with getAdapterPostion if you don't need to change anything in the views ?
Life and time saver! Thank you very much!
Thanks, it worked for me, I'm really happy, thank you so much!
please make a video on passing object as an intent. Great video btw;)
great, good job mitch.
It's worked to my project! Thanks a lot
Is there a Kotlin version of this video? I followed the Kotlin version of the making a Recycler View you made.
Hey Mitch! Would you make a short video on how to make an expandable recyclerview.
Each list item expands to show sub list items
Thanks.
Yes, please. We need that.
Look into Paging Library for Android Studio. Maybe that might be what you're referring to.
simple and elegant, thank you so much!
I can't do it I did everything as in the video it only works once when starting, after which it stops responding. It's probably because of the OnClickListener. Can it be because of the CardView that is in a different layout?
Activity is passed by (this) to adapter to create listener. So adapter has activity reference. But what's the difference to pass activity by reference and call method or field directly?
Hi Mitch, what if you have more than one click in the recyclerview item, such as a button, beside the main item.
Clear and to the point as always. Everytime I watch your video I learn something new. Thanks.
this is exactly what i was looking for. thanks :)
Thank you very much, you make me understand interfaces
Nice video. Very well explained.

Your voice makes this sound like casually explained: programming
pls mine is saying an error there is no default constructor in the recycle View Adapter
