[@eduardoreyes5203]

Nice video, awesome explanation, it works perfect on my app!

What if you need to have multiple activities? Do you just copy the bottom menu to that new activity?

[@AnimateMJ]

yes 100%

[@nguyendcb]

No, you need to use fragments

[@FilipeeX]

@@nguyendcb figured it out by now but thx lol

Everything went well, until the ActivityMainBinding. Good tutorial though.

[@castero465]

change it to name of the class next to name of xml activity Binding
for example if the xml file name is avtivity_editable the binding name will be ActivityEditableBinding not ActivityMainBinding

[@Mirtguitar]

@@castero465 Thank you mate, i had a typo in the binding name, now it works.

[@leychelle]

If your activity name is MainActivity then it will be ActivityMainBinding but for example if your activity name is LoginActivity it will be ActivityLoginBinding.
You have to call binding according to the activity with it's respective layout file

[@azlanahmed2811]

Set on click listener nhi call karna hai set on selected item method call hoga
