Did not think that I would get this about the case . list inside list Last week i have same case where i was getting list inside list i did search more but did not find something can help me So i had done it in the same way as u did . So can we make possible it in single recyclerview ? Because in multiple recyclerview difficult to handle the click event Interface callbacks of last recyclerview in main activity ... If yes plz reply me But i want to say thank you men U r Really...awesome

[@prakashmehta8872]

Yes u can do by using multiple viewtype jn recycelerview using view type. I knoe that much only u can search for this and implement if it goes well also tell me hoe do u do it.👍

[@beepst]

Thanks so much for this tutorial. I'd appreciate if you teach us how to filter one of these Section Recycler Views with a Search View.

Thumbs up, a great resource to tackle Sectioned RecyclerView. How to hide a section if there is no data?

[@RizwanAbbasi]

I tried this approach but if the middle section is to be hidden then there will be blank space in middle section, that's the problem. holder.itemView.setVisibility(View.GONE);

[@mafiacodes]

Because it shows empty section, I face u should return the number of sections from getitemcount, u have to make a check there also.

[@sat_talk]

Thank you sir.. How do we generate sectioned RecyclerView when the Model data class contains one of date/month/year String variable and we want to generate a Sectioned view based on each month and child as other variables like transaction Type, transaction Name etc?

[@gulfappdeveloper2849]

Thanks, It is veey useful to me

[@elmundodefer]

I want to thank you in advance for this video. I will try this on the weekend. I wonder how it will behave when a section (or more) contains so many items that it has to scroll to view them all. Will the different scrolls from each section and main recycler view interfere each other?

[@rahilsiraj3507]

Great video! Was wondering if we can make the section expand and collapse depending on whether we want to show the titles in the genres.

[@mafiacodes]

It’s possible

How can I connect the MainActivity from within the child rV? I try to set a view invisible onClick of a child rV item. I tried with interfaces, but I couldn´t reuse it with putting it into constructor, because the parent rV is in between the child rV and the mainActivity. How can I do this?

Congrats for the tutorial.. very good job! But, If one Section Item had nested items([ ] , {}).. how would you deal with that?

[@mafiacodes]

U have to use the same logic if nesting goes on, but that should not be done, u shud flatten the data

[@thaliaamargianou7870]

@@mafiacodes thanks for the answer..! But when you are getting the data from rest json.. they have a specific structure..! Usually the json raw data.. having nested arrays and objects..! In my case this is what I have to solve..! I want to use recyclerview and cardview.. and inside cardview under one item there is an array.. and there starting my problems...! I watched your tutorial and it looks easy but when you have normal structure of data!!! If you have complex structure of data.. you should use the same logic? Nested recyclerview inside cardview and then expand the card? Also for every recyclerview you must create an adapter or a viewholder?

[@thaliaamargianou7870]

or maybe I should use another way to display that kind of data? I will find my way I suppose!!! Thanks for your tuts...

[@thaliaamargianou7870]

@@mafiacodes is it possible to use this logic inside a cardview? Every section to be a cardview!!!..and inside the card to have the section Name + sections items?

U can but u might have rendering issues

Any idea how to refresh the items inside the entire list? I called notifyDatsetChanged inside MainAdapter but it did not work

[@RobinThomsonMusician]

Great video. Have you done a follow up video on how to open an activity from the ChildRecyclerAdapter?

[@mafiacodes]

Not exactly but you can simply create an interface and handle clicks

[@robinthomsoncomposer]

yoursTRULY Hi thanks Yeh I actually found your vid on using an interface to implement onClick

[@mafiacodes]

Glad that you like it

[@RobinThomsonMusician]

@@mafiacodes Got the click to work using the interface but now my Intent keeps throwing "Attempt to invoke virtual method 'java.lang.String android.content.Context.getPackageName()' on a null object reference" Cannot resolve it. Any ideas? Intent intent = new Intent(context, Waves.class); context.startActivity(intent);

[@mafiacodes]

The problem seems to be with the context, pass in the activity context if using activity or ur fragment context if using that

Use a boolean and store it in your database. Doing so allows you to retrieve only the ones which have the boolean set on true.

Sir how to open new recyclerView depending on selection form another recyclerView( if shirt is selected from category of clothes new recycler view to show all shirts )

[@mafiacodes]

Firstly if u want to open a new recycler view like u said shirts then u should implement onclick on section heading, if u select a shirt from clothing section then it shud open the individual shirt details page

[@Ghost-sc1my]

Are the list of items in each section srollable?

[@mafiacodes]

Yes

Thanks for replying instantly. Do you have blog or Website which shows this example that you have achieved. Actually i am facing RecyclerView: No adapter attached; skipping layout issues.

U can check the code on GitHub, probably ur missing layout manage

This is not correct. It shall be done with 1 RecyclerView and 1 adapter
