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

[Colton Idle]

I've had some problems seemingly after adding viewBinding, but typically a clean would do the trick. Also assuming you used <FragmentContainerView as the host?

[Andy Gibel]

ahh is that related? I was just using Fragment

[Andy Gibel]

which did work but gave me compiler warnings

[Colton Idle]

Oooh! According to Ian you have to use FragmentContainerView

[Colton Idle]

Because <fragment isn't really a view and so it messes a bunch of things up.

[Andy Gibel]

lol OK. /shrug Android amirite?

[Andy Gibel]

thanks!

I recently enabled VB because FCV is now finally a thing.

[Colton Idle]

I tried VB when it was brand new and it just wouldn't work with <fragment

[Andy Gibel]

ah ok. I was blaming that on the gradle plugin

[Colton Idle]

Once I moved over to FragmentContainerView the only issue that was kind of a bummer was https://issuetracker.google.com/issues/142847973… but thankfully it's starting to appear towards the top of google searches.

[Andy Gibel]

but yeah even in 3.6.2 was seeing issues with <fragment>

[Colton Idle]

Hm. @Ian Lake ^? The issuetracker is showing private?

[Colton Idle]

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]

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 https://issuetracker.google.com/issues/152333892

[Andy Gibel]

ah! You might check this out https://github.com/Zhuinden/ViewBindingExample/blob/master/app/src/main/java/com/zhuinden/viewbindingexample/FragmentViewBindingDelegate.kt

[Andy Gibel]

using a delegate makes it quite nice at the call-site

[Colton Idle]

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.

FWIW, it is the ... that is throwing off your link to the issue, it works when you go to https://issuetracker.google.com/issues/142847973

[Colton Idle]

Thanks Ian. That's what I get for copy pasting from twitter.
