RecyclerView (Kotlin Beginner Example)

[@IsZprAsGaminG]

You have become my master now. Among all the tutorials on KZbin, your videos are the one that clearly understandable

[@codinginflow]

Fake news

[@codinginflow]

@@codingwithmitch ah yea, my bad

[@DavidNitzscheBell]

6:27 you discuss for about a full minute why your `image` field is declared as a `String`. This is a case where the naming of variables is very important and useful. Call the field `imageURL`; this makes it clear to all, even deep in the middle of some chunk of code, that the variable points to an image somewhere and is not actually the (binary) image file.

[@gunther982]

The best android tutorial I have come across. So simple and understandable, whilst dropping wisdom and real-world examples. Love it

[@muhammadusama4437]

Select recyclerView item and take information from that to next activity/fragments. Also material design selection. This tutorial is awesome.

[@codingwithmitch]

I'll do an onclicklistener one next and nav to a new activity

[@brianssendagire262]

Thank you for your selfless share of useful knowledge. As a mobile app developer, you taught me Django web development with the Blog Course and I will without a doubt continue to pay for the online courses you offer. Let's support Mitch folks, pay for his online courses, he's an inspiration and a great guy.

[@codingwithmitch]

Thank you Brian

[@JoshMartin]

Why is there no usage of "findViewById" to reference the elements in the layout file? I keep getting errors of "Unresolved reference" in the BlogViewHolder class, but if I change them to "val blog_image = itemView.findViewById(R.id.blog_image)" then I stop receiving errors.

That's one of the most COOL tutorials I have ever seen in my life. You are awesome

[@raypaxman9600]

For some reason, I can't get the adapter to work. When making the "val blog_image = itemView.blog_image" aswell as the others, they aren't connecting to the other file where blog_image, blog_title, and blog_author are. so = itemView.blog_image becomes an error.

[@merttatli9455]

@CodingWithMitch Thank you for the content, i was tring to write the adapter code myself but i realized that when I implement BlogViewHolder i had an issue with itemView, it cannot see the layout properties. Is there any solution for it?

[@merttatli9455]

I find out that Kotlin Android Extensions is deprecated. That's why if you want to use this code you need to change it to 'kotlin-parcelize'

[@qwingus]

If you want to avoid dependencies on either of these, you could probably just do something like val blogTitle: TextView = itemView.findViewById(R.id.blog_title)

[@leonespartano]

Thanks Mitch. I'm really thankful for all your tutorials. Your form of explaining these complicated topics is wonderful.

[@codingwithmitch]

Thanks pal

[@mohammadatif2774]

wow clean and clear explanation

[@srdjansmulja5375]

HUGE HUGE THANK YOU! Really good tutorial, maybe the best one i saw from Kotlin tutorials. Keep up the good work mate!

All I ask is that you stay away from that Coding In Flow guy.

[@baijusharma6027]

Superb l was awaiting for these kind of tutorials on this channel. Keep going. Kotlin a new journey begins for Android developer.

[@iftak01]

Nice vid. Note: Synthetic view were used there in fun bind in ViewHolder Class...but its deprecated now. Good explanation tho

[@ziasheikh2863]

This video on recyclerview is superb. Please also make a video on recyclerview with endless scroll listener in kotlin. There is no quality stuff on this topic as i have checked many videos. Thank you.

[@RomskieL]

Thanks alot! You have explained so well the sequence on how to use the RecyclerView.

[@SK-fq2yz]

Please do Recycle view clicks in Kotlin

[@Milan-iw2kr]

Did he done it? I can`t find it :(

[@agoldfish9239]

Sorry for the late reply but to add an onClick just add this code right below 22:36 in the video on line 37 init { itemView.setOnClickListener { val position:Int = adapterPosition Toast.makeText(itemView.context,"You clicked on item # ${position + 1}", Toast.LENGTH_SHORT).show() } } Also if u want to add a little animation when you click each tile in your layout_blog_list_item.xml add these three tags to where you want it to glow android:clickable="true" android:focusable="true" android:foreground="?selectableItemBackground"

[@raypaxman9600]

Getting errors from list and ArrayList() both as errors. Edit: so I changed them to MutableList and arrayListOf() for now. Haven't finished the example, so I don't know if it'll mess it up.

[@PhilBrighton4]

This was very well explained, thanks. I want to create a recyclerview that uses two separate lists / types of data where one set of data follows the other on the same screen. I can combine them into a single list containing the two different data types, but I have been struggling to convert them to display in the two different views . A video covering this would be a godsend to me :)

One question, in your DataSource class, why not simply just do object DataSource() as opposed to class DataSource then declare the nested companion object? Thanks!

[@ziasheikh2863]

Hello, i hope you're doing good. Thanks for such kind of great videos!!!. Can we control card elevation behaviour? I mean by using card elevation we got a shadow but it is very sharp shadow... Can we control it's sharpness?

Hola, muy buen video, estoy aprendiendo kotlin y este tutorial ha sido el que mas me ha servidor :),,,, tengo una consulta por cierto,,, estuve haciendo unos cambios en el data source para poder obtener la data desde internet y cuando lo ejecuto no pasa nada,, sin embargo cuando le pongo un delay de 2 segundos carga perfecto con la info de internet,, supongo que el problema va por el tema sincrono y asincrono,, entonces,,,sabes alguna forma de hacerlo asincrono para que cargue en background y luego presente los resultados?,, o por ultimo bloquear la app hasta que espere el resultado del GET.

[@calvinusiri9498]

Hey Mitch, thanks for the video. I know the example above is for beginners, but how would you solve for a situation where you are loading images async with glide and scroll up/down really quickly with your recyclerview. Because the views are being recycled, and Glide is async, you'll have the incorrect image being shown on your Imageview for a moment before glide catches up with correct image. Do you know of a way to handle this without clearing Glide or setImageBitmap(null).

[@codingwithmitch]

No that doesn't happen. Just use it as I showed you

[@DavidNitzscheBell]

I think it would be more descriptive to call your `image` variable, `imageURL`.
