Great Tutorial man !!!! I am watching your every single video in this series and I AM LOVING IT!!!!
Thanks For Such Valuable Content
MIllions subscribers on your way.
Thanks man!
Thank you very much. This is the best tutorial on this subject
Thank you for a very detailed tutorial.
You can add this implementation guys.
implementation 'com.google.android.material:material:1.2.0-alpha05'
since setOnNavigationItemSelectedListener is deprecated
use setOnItemSelectedListener instead:
bottomNavigationView.setOnItemSelectedListener{
when(it.itemId) {
R.id.messages -> setCurrentFragment(fragSecond)
R.id.profile -> setCurrentFragment(fragThird)
else -> setCurrentFragment(fragFirst)
}
true
}
Is this method still working buddy?
@Emprende Libre 'when' is not a method/function. It is part of Kotlin's conditional statements/expressions you can learn more about it here ruclips.net/video/dSsLy-_pPI8/видео.html
Here I am using when as a statement to check every item id and set my fragments accordingly
Very good , now I am feeling like a developer 😁😁
This right here! nothing less than divine. Thanks Philipp
Thanks!
New channel, yet the quality of this tutorial is gold
Thanks!!
Cool Information, it appreciate for a New Development !!!
Thanks sooooo much. So clear!
İ finished it! great explaining! you are awesome!
Thank you❤️
since setOnNavigationItemSelectedListener is deprecated
use setOnItemSelectedListener instead:
binding.btNav.setOnItemSelectedListener {
when(it.itemId) {
R.id.miHome -> setCurrentFragment(firstFragment)
R.id.miMessage -> setCurrentFragment(secondFragment)
R.id.miProfile -> setCurrentFragment(thirdFragment)
}
true
}
Hope it can help you
Thanks, but do u have any solution for this? wtihout deprecation
thanks man for saving my time
Thanks for the explanation..
Btw i have a question
If i want to get the data from another activity and i want use that data on my fragments (first fragment and second fragmen), should i use intent on each fragments or only use intent on the activity??
16:43 there are nothing to improve, your explanation is perfect
You are my Hero! Thank you so much!
Glad I could help!
Thank you so much mate!! :D
great Tutorial man !!!
these are all very good tutorials, I am watching each one, but these are getting somewhat confusing, could you provide an overview at the beginning so we can see how all these files and built in functions work together? You explain what each function does but if you could further explain what each function in terms of it's relation to the other functions and lists etc. in other files at each step, it would help. Keep up the the great work! and thank you. netninja provides a good level of explanation, he may be a good model to follow?
Speechless !!!
Great video!
Good bonus ! Great Videos so far!
Thank you!
really informative !!!!!
how can we change the title of action bar at top , when clicked on particular icon from the bottom menu?
for e.g on clicking home it should display Home instead of Tutorials, same for others too.
What if I want to set the counter based on the amount of nodes that get added to my firebase Database? Or when I add a layout to my recycler view adapter? Basically making the counter Dynamic.
Wunderbar tutorial meine freund, ich liebe dich
Thank for the video, it helps me a lot! I have one question, i did the same as you but at the time of running the App, each time i touch an item, gets double in the screen. I start in home but when a touch another item, goes to that fragment and the homeFragment stills there. any help?
New subscriber 😎👍
Helpful
Thanks it works perfectly hahaha, i just miss the commit line sorry for that
Hi Philipp, this is such a wonderful video. In the beginning of the video (0:16) you mentioned 'it should have at least 3 fragments.' Is there any particular reason for this?
I've tested using two fragments and it seems to work fine so far. Any comment on this issue if you may?
I think it's a convention of the Material Design Standard, not about a technical reason.
Hey In the fragments we added (addToBackStack) to remember the stack of fragment. I want to also synchronize the bottom navigation items with those stack. When clicking the back button only the fragment's stack is used.
Is there anyway to also remember the stack of bottom navigation synchronized with the fragments while using back button?
If you have answer please comments friends!!
EPIC!
After i create the botton button view can i just create buttons on a created fragment and everything will show or is there another step? Im trying to create a sple menue on one of the fragments with a button
könntest du das nicht auch alles auf deutsch machen :D sehr hilfreiches video danke dafür
How can I add a coloured line below the selected item in bottom nav ?
the code is little bit deprecated i cant reach the change between fragments.
Could you make a video how to save fragments state when switching between them with bottom navigation bar (using xml and navigation component). It would be really helpful for beginners. Thank you!
You are probably gonna want to use a ViewModel for that, I think he has some videos on that.
Great video! I wonder is there any chance you can upload these mini projects on GitHub so that we can copy/paste some parts?
Thank you for the feedback! That's a good point, but sadly I don't have all the projects anymore. I think I will start with this in my next series from the beginning on
@@PhilippLackner that would be great, thank you :)
i Just want to add back stack in every fragments how i can ? i mean addToBackStack(null)
good
How we can add recyclerview in fragment?
Hey!
You forgot to paste the dependency in the description box
This was awesome, but I wonder, can I use three separate activities in place of those three fragments. is that possible ? and is it easy to do so ?
wondering the same
How can I move everything from main activity to Home Fragment ?
I have error on bottomnavigationview.setOnItemSelectedListener in main activity why?
How can we test bottom navigation using espresso
Philipp are you using kotlin x is it still working kotlin x is deprecated now
Really useful tutorial but do you have the same tutorial for Java instead of Kotlin? Thanks
I was faced with this same question and decided to scrap working with Java and move onto Kotlin. I watched is Kotlin playlist and am now here on this playlist. While I took my time to get here I am happy I did and ready to move forward using Kotlin. I would suggest anyone who is at is using Java to do the same.
I wanted this video with java
You have recorded this video in Mar. But by now the dependencies in build.gradle file could have have been updated. From where do i get the latest dependencies. if you use the dependencies you mentioned it is showing error
you can just hit alt+enter and it'll find the latest version
sir how to get the dependencies like for bottom navigation bar you have a dependency where will we get those dependency
you find them by googling
setOnNavigationItemSelectedListener is deprecated, we need to use onNavigationItemSelected
Still can not understand diff between vector and image assets.
Dear sir I got an error when I implemented the dependency
com.google.android.matetial: material:1.2.0-alpha04. The error is that - DSL method not found implementation ()
implementation 'com.google.android.material:material:1.2.0-alpha04'
implementation isnt working. showing error, has it changed since you made the video?
Is anyone having the problem where the XML preview disappears just like in the Fragment video when we dont mention the tools:layout = "@layout/first_fragment" line in the fragment tags? if so does anyone know how to fix this problem?
i fixed by downgrading the material version from 1.5.0 to 1.4.0
u need to click on the ! icon, then again a popup from bottom will appear, then again it will show the ! icon on the bottom pain, click on it, anothe popup will appear to the right with 2 li ks highlighted in blue, click on the second one
I don't know but the bottomNavigationView.setOnNavigationItemSelectedListener() is not working for me. it's not even coming in the auto completion. if anybody could help.
replace with setOnItemSelectedListener
Bro i have downloaded icons but when i am adding them they are not showing up instead empty square is showing up what to do
notice that you have icon_name_foreground and same with background, use the foreground and not the background when selecting the icon to attach
Realy sorry i.m a beginner. And need help. Fragment 1 must be a webview . Must i make this is in mainactivity or in fragment 1 .XML. all the tutrorials begin with a new app. Sorry i want to understand it.
I don't really get you, but if you ask where you should put the webview, then in the fragment XML if you want it to be displayed in the fragment
@@PhilippLackner so if i get it now. i must first make a splash screen . Than the menu with fragments and within the fragments i must made the other stuff.
Surely, there must be a simpler way.

Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException: Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
This is the error I'm getting while doing the projects what can I do to resolve this error i cant find any answer in stack overflow and any other sources, also tell us where can we get solutions if i get errors ?
in my values folder, there is no styles.xml file ..
now its themes>themes.xml
how can we change the name of the toolbar? everytime the bottom navigation is clicked?
You mean the title?
@@PhilippLackner I think it is
Clicked from bottom nav
Maybe using ActionBar..
Set the ActionBar name with the title name (for this example home/ messages/ profile).. cmiiw
where is dependecies?
why don't you use jetpack navigation?
Because it’s cheeks
@@LaBoots i changed my domain lol
sorry i forgot to put the commit lol
how can we add buttons in here?
Where do you want to add them?
@@PhilippLackner in the fragment itself, i have a problem that encounter, the textview do not appear even that i follow your instruction, what could be the problem, i am using the latest android studio
@@PhilippLackner not just button but also something like recyclerviewer,
everything works up until 15:00

@@edenlu1331 Thank you
A comment for promotion.
getorcreatebadge
Doesn't work. Don't bother
I find that addToBackStack can add fragment to the stack. So, is there any listener which can let me know the stack is pop out? Because I want set some status of the fragment.
Or there will be some other functions?
binding!!.btnFragment1.setOnClickListener{
if(state != 0){
supportFragmentManager.beginTransaction().apply {
replace(R.id.flFragment, firstFragment)
addToBackStack("0")
commit()
}
}
state = 0
}
As of Jul 2022 I had to use binding.bottomNavigationView.setOnItemSelectedListener {} to get this to work. Hope this helps!
