Thanks!!

You can add this implementation guys. implementation 'com.google.android.material:material:1.2.0-alpha05'

[@ste1516]

16:43 there are nothing to improve, your explanation is perfect

[@yadude101]

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?

[@MCA_HimanshuSeth]

Very good , now I am feeling like a developer 😁😁

[@riteshgeddam3619]

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.

[@MMB3245]

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?

[@alejandroflorez9409]

I think it's a convention of the Material Design Standard, not about a technical reason.

[@chris_rb84]

You are my Hero! Thank you so much!

[@PhilippLackner]

Glad I could help!

[@wowovanmbothen]

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??

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

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

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.

Thank you!

[@LaurinusPonpon]

Thanks sooooo much. So clear!

[@josephgellida]

the code is little bit deprecated i cant reach the change between fragments.

[@Somerandomnessvvv]

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 }

[@tushankdutt8954]

Is this method still working buddy?

[@Somerandomnessvvv]

@Emprende Libre 'when' is not a method/function. It is part of Kotlin's conditional statements/expressions you can learn more about it here kzbin.info/www/bejne/moTWfaxjlNWDf5o Here I am using when as a statement to check every item id and set my fragments accordingly

[@srini01]

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

[@thekralj9600]

you can just hit alt+enter and it'll find the latest version

[@tomasyedid3140]

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?

[@sasidharan1937]

Speechless !!!

[@TheImaginativeSachin]

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!!

[@Anshu_nisha]

I have error on bottomnavigationview.setOnItemSelectedListener in main activity why?

[@android-dev]

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!

[@knflux9840]

You are probably gonna want to use a ViewModel for that, I think he has some videos on that.

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?

[@un7sh226]

i fixed by downgrading the material version from 1.5.0 to 1.4.0

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 }
