I have trouble where I place an advertisement, my array misses every 3rd position (arrray[0], array[1], ad, array[3], array[4], ad, array[6] and so on...) How can I solve it?

[@slash0t5]

This is an excellent video. However, you left out the part where you insert the advertisement image. How would you do that?

[@Codetutor-DemystifyCoding]

Thanks... I never had the intention of actually inserting an ad as focus here was to demonstrate heterogenous rows in a recyclerview. But adding an ad should not be a major problem. Typically it would be an image. It's just matter downloading the image and putting it in the ImageView (provided you have the imageview in side the row layout). Lot of libraries are there for doing this like picassa. Hope this has been helpful to you.

[@slash0t5]

@@Codetutor-DemystifyCoding yes it was extremely helpful. I was using Firebase UI Firestore and had to rewrite the entire code because that library doesn't support heterogeneous view types. I ended up using Glide instead of Picasso and it works.

outstanding tutorial

[@indrajeetjyoti9020]

Sir my question is that in Facebook or any news app first ten view or first ten position of recycler view is loaded after that some loading view show then again next ten data load in recycler view

[@Codetutor-DemystifyCoding]

Oh.. it's a combination of multiple things. First you need to create a endless RecyclerView. There is a way to do it. Basically you keep track of scrolling and when scroll reaches a point you add more row items to RecyclerView. Also you need to load the as late as possible to make this as efficient as possible. You need to use the concept of lazy loading for this. Also you need to cache data to make it perform better. These are very interesting but bit advanced concepts and I am not covering those as of now. This should be good enough hint for you to search on other forums. All the best.

[@mubin986]

good explanation. but, if you used generic recyclerview adapter and generate viewholders with factory method pattern, your code would become smaller and reusable for future use. thank you.

[@Codetutor-DemystifyCoding]

Of course.. in a real production quality code, I would do that. This was meant for beginners. Thanks for commenting.

Nice Tutorial Sir It Worked Perfectly in Linearlayout manager .. I tried it in Recyclerview with GridlayoutManager ( 3 column ) but its not work perfectly ... So How Can we Do It,,..??

[@Codetutor-DemystifyCoding]

Are you getting an exception or is it just that data in layout not getting displayed properly? If you are getting the exception - Did you debug it? What Exception is it giving? Did you do Google search on that exception? If it is just a unaligned display issue - you will have to just redesign layouts for row items to accommodate large data in smaller area (play with font sizes, widths and heights). Hope this helps.

Sir how to set click listeners for items in each row and start separate activity for each item. Thanks

[@Codetutor-DemystifyCoding]

Click evens on Row items in RecyclerView has been explained in one of previous videos in this series. Please visit: kzbin.info/www/bejne/n3fQi6mdp8hnn5I Starting an Activity from there should be straight forward. If you want to know general concept of how Activity is triggered, I have a another tutorial series. Pleas visit: kzbin.info/www/bejne/habHaqOpm7eJorc

[@siphamandlagcabashe5169]

Hello Sir, How can i decide the view to be displayed based on something retrieved from the database?

[@Codetutor-DemystifyCoding]

Yes.. This is very common scenario... Instead of Two (as shown in demo) you need to design for more options. That's all. Complexity increases.. but still works perfectly fine.

[@kaboomstudios8416]

do you have any video on this

[@babintandukar8917]

i hope it helps to futeure who come across this prob i achieved it by infalting layout on based of boolean which i get from my list.. Model model = list.get(position); if(model.getboolean){ return whentrue layout }else{ return whenfalselayout }

[@vishalkumarsonawane7334]

Very nice tutorial. You taught a very deep concept of android. Please, can you help me to build logic to display 4 heterogenous vies in recycler view. Each view item repeats after 3 different items.

[@Codetutor-DemystifyCoding]

I am almost tempted to give answer but I will hold back.. You can do it by just changing the logic in getItemViewType. I have already shown how to do it one one scenario. It's just matter of figuring out what logic should be in place for your scenario. Just download this code from Github, debug it and modify it to get what you want. I am pretty sure you will figure this out on your own. Best of luck.

[@ideepdave]

Issue i guess is with dataList,size(); where we have to add equal number of items of adviews.

How to remove all data from recyclerview and insert new data

[@Codetutor-DemystifyCoding]

Just clear the List and invoke notifyDataSetChanged on the adapter. That should do it.

[@eddykwang]

Databing with event handling for Recyclerview pls!!! thank you.

[@indrajeetjyoti9020]

Nice Sir update this tutorial!but how we load data from recycler view every 10th position

[@Codetutor-DemystifyCoding]

Oh.. looks like you were waiting for this video.. You got to modify getItemViewType. I have used modulo 3 operation. If you want to change this you need to change that internal logic of getItemViewType. Actually at the end of this video I have said that there is issue with this implementation. Try to figure out what is it. I will be unravelling it in next video.

hi can i ask you directly to email?

Please don't mail me. I can't keep answering similar questions from different people individually via mails - it's just inefficient. Any doubts regarding video and concept, put them in comment section. If I answer them, that will help others as well.

[@anggitprayogo6436]

okey, the concept is almost similar. i want to show ads in every 5 items in recyclerview. but i have 2 diffrent source data that i store in list to show news response and ads response from api. how to handle that 2 diffrent list in recyclerview adapter to show ads in every 5 item of news?
