Does anyone else have near constant problems with Viewbindin

Question

Does anyone else have near constant problems with Viewbinding navigation components and Android Studio not recognizing the generated Kotlin code

Colton Idle · Answer

I ve had some problems seemingly after adding viewBinding but typically a clean would do the trick Also assuming you used ` lt FragmentContainerView` as the host

Andy Gibel · Answer

ahh is that related I was just using Fragment

Andy Gibel · Answer

which did work but gave me compiler warnings

Colton Idle · Answer

Oooh According to Ian you have to use FragmentContainerView

Colton Idle · Answer

Because lt fragment isn t really a view and so it messes a bunch of things up

Andy Gibel · Answer

lol OK shrug Android amirite

I recently enabled VB because FCV is now finally a thing

Colton Idle · Answer

I tried VB when it was brand new and it just wouldn t work with ` lt fragment`

Andy Gibel · Answer

ah ok I was blaming that on the gradle plugin

Colton Idle · Answer

Once I moved over to FragmentContainerView the only issue that was kind of a bummer was but thankfully it s starting to appear towards the top of google searches

Andy Gibel · Answer

Anyway the issue I was getting was at runtime it didn t like that in my activity I think I was calling getNavController or one of those convenience methods and it didn t work If you search for that runtime crash you should get an SO link to point you in the right direction But yeah that was my only real issue with getting VB started That and I had a couple of include and merge tag issues that weren t exactly clear but now that I have VB It s amazing

Colton Idle · Answer

Also you probably saw it but doing the whole VB dance in a fragment kinda sucks Its ugly < evant> got a nice shoutout in this issue I filed

Colton Idle · Answer

I did see like 5 different solutions so far I also saw one interesting one that jw seemed to like where you use the views tag But I do like evans article I think trying to limit view interactions to onCreateView and not holding onto the field is where I d ultimately love to go
