Lists - Android Jetpack Compose - Part 8

[@bytegraftkids]

Thank God! The old days of recyclerview are gone. Very well explained.

[@hadjsaidaoumer3058]

Thanks Philipp 🥰 , You are the best teacher 🙏

A new era has just begun in Android Development.

[@nilanjanmukhopadhyay8369]

Not only in Android. I hope all other front-end frameworks would follow this trend. Front-end has never been something that is brain intensive. Still, its messiness has always freaked out developers. It's a new era.

[@AleXoTroN]

As a long since flutter developer, i just love how lists are created in compose. Its soooo much easier

[@TiagoDvl]

I truly think your content should reach a higher audience. Thank you so much for this.

[@thyagonevessilvestre1248]

I agree, at least here in Brazil Phillip is well known as a reference in Android development.

[@durrium]

Following your tutorial series and I gotta say, you are doing agreat job! Many poeple dont zoom in on the variables and functions like you do :) Keep it up!

[@PhilippLackner]

Awesome, thank you!

[@animecontent232]

oh my gosh, bro, how simple it is, I was straggling in xml to create a list with fuc*ken adapter and many functions. I love you bro.

[@alexwhb122]

Fantastic video! I actually can't believe how much better JetPack Compose is than old school Android view programing. I literally can write what would have taken me days in hours or less. I'm so excited about the possibilities this allows us.

[@dawidtyburek]

As per todays Reddit: Compose is when you're tired of needing to create 7 files to display a list of items without a header 🤠

[@halahmilksheikh]

Someone needs to start a gofundme to get this man a transparent mic. Kidding, I love your stuff! Very thorough.

[@tonnie7079]

My takeaway - If you only have a count then use items (100) { i -> }. If you have a list and you need an Index then use itemIndexed(listOf("s1", "s2")) { i, s -> }

[@mrpi230]

I liked LazyColumn and your great teaching style . Thank You. 🙏

Thanks Phillipp, with you I am learning a lot, I understand you while with the other people I haven't been able to do it.

[@omargaccetta6579]

My God, I can't even believe this can replace recyclerview, so simple and succinct.

[@faysaldeve385]

Your explanation is very wonderful and you are a beautiful person and artist. Thank you for this excellent course

[@Laithabujbara]

Keep up the good work 💥

[@LiranBarsisa]

I have some questions: 1. Is Compose more efficient than XML and/or direct creation of Views? It seems like it could get many instantiations, no? 2. How does Compose work exactly? 3. Here you show a replacement for RecyclerView, but what about how you load data dynamically and need to set it? You will need to set an ID per item , too, no?

[@resulakn688]

i have same issue

[@nayls1987]

In case anyone gets stuck like I did, it looks like you have to actually have more items than will fit on screen, or the items won't actually scroll. i.e. - the last example shown won't scroll because everything already fits on screen.

[@twojaStara698]

Thanks for amazing course. I love this so much

[@kravets_coding]

Looks much better then recyclerView. Great tutorial to get familiar with the concept. Thank you. Still I have questions I have to find answers for before I can trust the lazy column thing: does it recycle old elements as we scroll, how to implement scroll bar, what about pagination.

[@tomsaju1970]

Thanks for the tutorials Philip

[@JohanMosqueraYT]

Thank you Phillip, the best Android Tutor 🔥

[@xavierrispal9605]

Thanks Philipp for this quite interesting video. Have you tested LazyColumn with a more sophisticated usecase ? I agree, recycler views are way too complex but when you master them, you can display in the same list quite different items according to their types and that's quite powerful. The dependency from Hannes Dorfmann is very useful to reduce boiler plate.

[@PhilippLackner]

The same is possible in compose, just use an if-statement to determine which composable to show for an item. You can also use multiple items blocks to display multiple different items together. No more XML layout, no more viewholders, no more adapters

[@xavierrispal9605]

@@PhilippLackner Thanks, I will give it a try :)

[@hpmusicbytes]

@@PhilippLackner I tried loading different composable in lazy column.but it affects the smoothness in scrolling of lazy colmun. I tried including lazy row as item in lazy column. Any work around on this

[@colinf6266]

you are a legend! thank you

[@sarahmohamed2973]

it is really super easy than the old recycler view approach

[@saharas7635]

Great, thank you philipp

[@erickramones2167]

please consider using a gist. maybe doing commits for each example.

[@abhas_kr]

Lazy column is similar to something I used to dreamt of when using Recycler View in XML.

[@OmarHawari]

For real Recycler View is such a pain in the ass

[@haoqian1465]

Nice video. Can you make a video on using LazyColumn with Pagination?

[@amineayachi335]

oh god finaly i dont have to create adapters for lists thanks

[@swiftyassistant1225]

Hi Philippe, thank you for this very good tutorial! Only I have a problem, when I launch my app on my physical phone, under android 12, when I scroll it's really not fluid and I don't understand why!

[@Rafael-hk9pg]

Hi Philipp, thanks again for your amazing content. I was wondering if you could push me into the right direction: I am trying to create a list where the span size is different regarding the listitem position. (if (position % 3 > 0) 1 else 2). How to achieve this?

[@nipunkumarit2168]

Lazy column is made for relaxed our finger , because recycler view is just too lengthy to implement and also so may files for this....

[@cinnybun739]

Lazy column is godly.

[@andriibibik39]

Thats nice. LazyColumn is easy.

[@JujareVinayak]

Pls do a tutorial when there are different types of viewHolder(item types)

[@elijahonduso]

Man you're a god

[@akthamahmed2171]

Nice 🧡 Finally No More Adapter And ViewHolder 😅

[@dmytromarchuk3023]

Just wandering if there is out of the box implementation for paging in Jetpack Compose

[@bismeetsingh352]

Can you explain those scopes?

[@HaiderAli-gi1fn]

this was very nice i lovw it

[@tommy9x]

Get lost from item index, why there is no int parameter in the function?

[@MuhammadYousaf-tp9mi]

how are you using $it for indexing where did it come from??

[@cc_1enjoyer487]

brother you should replace item with items, I made the same mistake, LazyColumn{ items(5000){

[@AAKASHPanchal-s2f]

Thanks Dude 😊

[@SahilGargjava]

I tried the same approach but for me, LazyColumn stuck on first scroll and then after that it scrolls smoothly.

[@valizeth4073]

Using jebrains compose but it's an excellent feature

[@TLTthatsME]

Can u use groupby?

[@aliziyad6473]

I'd suggest you use contentPadding and Arrangement to apply padding on LazyColumn. contentPadding is used to add the padding before the first item and after the last item. Arrangement is used to add spacing between each item.

[@omdeep4137]

Can this work as a table

[@a-zlearning6259]

Why am I thinking that XML is much simpler and easier? 😔 I mean it is so complicated and even when creating an Edit text you should change the state and take care of it, we cannot even just set an on click listener for a button to change a textview easily, it is so complicated and much code to do in jetpack compose. 😔

[@l201012]

Because this compose thing is so not good. XML was better. Also I don't understand why the collegue said you have to create a lot of files with XML. Only two files. And only 2 files from Recyclerview. I think you now got the same coding things like in flutter. Why? If I want to create this ugly one on file shot codes and states I just go to flutter/dart. Android was the nice XML + code style.

[@l201012]

Also if u create components outside from the main file, you have to create a lot of other components too. It is like a flutter dev don't want to use android and kotlin anymore, so a flutter dev wrote an ugly wrapper for android native :)

[@thyagonevessilvestre1248]

Looks like a dream...

[@DanielLuche]

Very good

[@sudarshansingh1072]

Thanks to jetpack, life is easier now. (Isn't is inspired by Flutter)

[@newbiegameplayy]

So we dont need recycler again?

[@matt-g-recovers]

I love it!!

[@itmeocon25]

If use Scaffold nested column or lazycolumn, it won't scroll

[@zepra2133]

easier from recycle view 👏

[@soma7891]

For this singley Jetpack Compose is better than XML

Lazy column is very simple than recylerview.

[@bboydarknesz]

Why you keep look your keyboard XD

[@Khdkss]

where is the so called adaaaapter😂😂

[@nightfury1390]

WTH so simple

[@anudeepananth]

This is great... but the performance is beyond horrible... Recycler views run buttery smooth even on android phones which are 5-6yrs old... Just waiting for LazyColumn to get there performance-wise... LazyColumns stutter even on modern flagship phones...

[@RodrigoAbreuOliveira]

show!!!

[@karentechnologies3990]

Great and short video. but why you didn't mention how to implement onItemClickListener()?

[@PhilippLackner]

because that's not related to lists, you just attach a clickable modifier for that

[@str2254]

I've created a list with 1000 items and scrolling feels really lag for the first seconds or 100 items, the it gets smoother. Do you have any idea why? LazyColumn { itemsIndexed((999 downTo 1).toList()) { index, item -> Text( textAlign = TextAlign.Center, modifier = Modifier .fillMaxWidth() .padding(16.dp), text = "$index: $item" ) } }
