BUTTONS - Android Fundamentals 

Worth pointing out that Kotlin Synthetics (Which is the feature [Extension Plugin] that allows you to call your Views (Buttons, Edittexts, etc) with their respective ID directly onto your Kt file/class is deprecated, which in general means it is not recommended to use anymore, instead it is good to use ViewBinding or DataBinding (or both if needed).

I was going through a bunch of videos on RU-vid trying to look on getting into Android Studio with Kotlin since it is the new language going forward by Google on Android. And all of the videos I could find would show you how to do something but not really explain what each part of the video does. For example, the way you broke down the meaning of "R.id.but..." to indicate this comes from resources and ID's, it's something not many do. Thanks for making this fundamental series, it has been super helpful so far for someone looking for a concentration in their CS degree ;)

Anyone please help me in my Android Studio it doesn't work when i type btnApply it shows create local variable also there the import library doesn't work i Tried many places still im stuck . help me

from 2021 and I got problems when I have tried to import views by using "synthetic". But I have fixed it by replacing with 'view binding'. Great tutorial bro keep going on!

to do what he did in this video you need first to learn about view binding in this videos ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z0F2QTAKsWU.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QVIgunA3jcQ.html this will help you to understand how android studio calls view by id now after that you can follow with the setOnClickListener part because after you call the button its the same in both ways

Hi Philipp, How do we import a button nowadays (Oct 2021)? the alt + enter method doesn't work anymore.

I'm following this course so far but when I click alt + enter at 7:30 it doesn't import anything, I've tried manually typing it but kotlinx doesn't even autocomplete it only says kotlin

Followed along through your entire Newbie to Pro series, and per your recommendation, I'm going through this series to learn XML before jumping into Jet Pack Compose. This is my first time committing to learn to program since my Web Design HTML/CSS days over a decade ago. Anyways, THANK YOU. You're videos are not only well thought out and made, but your playlists are well structured and paced. I actually feel confident that I can be good at this because of your tutorials and advice. Figured after having watched 30+ videos of yours, I should stop and express my appreciation. Keep doing your thing!

Thank you Professor God Bless You from Senegal Great Job Enjoy you contribute to the humanity

Just in case if you are following along this tutorial as I am so the import " synthetic " is deprecated but Philipp has made an updated video using View Binding. Just keep coding. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z0F2QTAKsWU.html

Wow holy crap these videos are easily the best coding tutorial videos I have ever seen. I am a complete beginner and self taught (more youtube taught honestly) and you are by far the most helpful.

first of all thank you so much for you very useful curse and then I have a question in the 8 min where you teaching about "importing btnApply" it dosn't work for me I pressed Alt+Enter but it didn't work can you pleas help me to fix it?

Phillipp, your video about buttons is extremely good. Your tip about renaming buttons is very important. I had problem with renaming buttons. However I need button to save data in database - to implement Insert statement. I do not know how to do this in button.onclick. Could you please show this in comment. Because it is important for all Android Studio beginners. Or can you make video " Buttons to save and delete data in database". Thanks a lot

Great video, bro. I finished an Android App Development course on Udemy, and I'm now using your videos for review. These are helping tremendously. Keep up the good up work.

if you add ads, i pleasure to watch it. thank you so much for good explanation

Love your videos. Could you also show how to do this stuff in code besides the design views?

Great Tutorial. You are what is getting me through my Mobile App Class. Thank you!

I love how much this looks like Visual Basic but with OOP

Being a Java Developer at 7:18 i realized (one of the reasons maybe) why u hate java & love KOTLIN

Hello, I'm a newbie here. Many thanks to your video, one of the best explained android tutorials! Some issue occurred when I followed steps in the video Program compiled fine, but my emulator still showed "Hello World" layout, which is really strange because in the previous Linearlayout video the app ran no problem. My first thought is it's maybe android studio had some syntax updates during this time since 2020? I've googled it but most answers were so many years ago. Sorry if the question sounds stupid, would appreciate any help, thanks!

While running Android studio emulator when I increase the volume of the emulator it got crashed and showed blue screen error what could be the possible reason ??

Great series!

couldn't add my view directly in main activity. not showing any import

to solve button problem: - add : apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' to your build gradle (module...) -add : import kotlinx.android.synthetic.main.activity_main.* to your main activity

Perfect explanation :)

How do we import a button , the alt + enter method doesn't work anymore

Nice 👍

First - thanks again and again for the videos. Second - Just a suggestion, you do not have to accpet: Instead of teaching us the shortcut to refactor (and we are familiiar with many other), right click and show us the popup menu - refactor All the best :)

Hey I was following this tutorial and I tried using the Alt enter shortcut and it didnt work I then tried doing the import with kotlinx and it didnt give me that as an option is this something I have missed during the setup? Other than that loving this content just finished your kotlin newbie to pro course and I never knew I could fall in love with a language but I think I have lol

why the placeholder text in the edittext fields stay when i write something

just binge watching

What is the difference between left_to_left_of and start_to_start_of?

Mad respect

Great
