How to create a Bottom Navigation Bar in Android Studio (Kotlin 2020) 

Agreed! I'll try to kee everything up to date on my channel!

findViewById(R.id.bottom_navigation).setOnNavigationItemSelectedListener { when(it.itemId){ R.id.ic_home -> makeCurrentFragment(homeFragment) R.id.ic_favorite -> makeCurrentFragment(favoriteFragment) R.id.ic_setting -> makeCurrentFragment(settingFragment) } true } this works for me

@@swethaaresetty3105 It's working. Thank you so much :)

try findviewbyid

@@Indently would i put this in the main activity?

Check if you surely used the "setOnNavigationItemSelectedListener" and not the "Reselected" one.

Hey Rifqi, no problem at all, I'm happy I could help!

you ever got this resolved?

I'll work on it! Thanks for the support!

Hey, I wouldn't be able to answer that without doing some research on Google. Have you already tried writing the same question on Google?

@@Indently yo, just figured it out tho, i could just add {} in the navigations and it actually worked

I recommend searching the navigation component which is part of the new Android recommended architecture components. It makes life easy

@@Indently ok thanks

yes

use findviewbyid

TRY THIS val bottom_Navigation = findViewById(R.id.bottom_navigation) as com.google.android.material.bottomnavigation.BottomNavigationView bottom_Navigation.setOnNavigationItemReselectedListener { } }

Hey Sebastian! I can't help with the amount of information provided, but I definitely recommend asking on Stack Overflow. Either you missed a very small detail, or it could be something else. Thanks for commenting :)

I haven't tried, but it should work the same unless they explicitly updated something in the documentation. But just try it out!

@@Indently hi, thx and imma try it out btw quick response :) nice!

@@Indently hey code palace, i have a problem, so in one of my fragments i created a logout textview but how do i make it so it makes me go to another activity from an onclicklistener?

did you find a solution?

@@jevitamariasaldanha1618 nope but its too late anyways

did you find a fix?

I would have to do some research, but can't you just use layout_above or something in the XML so everything gets placed above the navigation bar?

@@Indently i never thought of that i have to try it out thanks

@@theguywithatimemachine436 Did it work?

@@muminoloruntola2146 yes i managed to archive this but i did it using java

@@theguywithatimemachine436 Oops I don't know java.

Type it in google

Maybe you chased wrong Layout type?

We’re sorry to hear that you’re facing trouble with this tutorial. We have some suggestions for you: - First, try watching the tutorial again to check if you missed something (remember that programming languages are strict, and that uppercase & lowercase characters are completely different.) - Second, if you’re facing an error, try copying and pasting it into the Google search engine, it’s the fastest way to find the best response for the issue you are facing. - Third, if it’s still too confusing for you, try taking a step back and working on an easier project to try to improve your programming skills before tackling the project in this video. We wish you the best of luck with your project!

Kotlin automatically converts this into Java already, try Kotlin.
