Kotlin Android View Binding: Kotlin Android Extension Problem

Question

I'm trying to do View Binding in Kotlin and fragments.

val button: Button = view.findViewById(R.id.Rutton)
button.setOnClickListener{
    //do something here.
}

but when it has many objects. I need to define that. So I had to look at:

Kotlin Android View Binding: findViewById vs Butterknife vs Kotlin Android Extension

and

Android developers documentation DataStore Overview: View Binding

but I can't find ResultProfileBinding in my Android Studio

What can I do in my program?

What is your *layout file* name you have keep ? Also check if you have added *dataBinding* enabled in *build.gradle* file or not. — Jay Rathod, Dec 23 '20 at 11:55
It's ```fragment_fast_login_page.xml```, and I put ```buildFeatures { viewBinding true }``` in my build.gradle — 張聖坤, Dec 23 '20 at 12:00
Then try to right *FragmentFastLoginBinding* like *private lateinit var binding: FragmentFastLoginBinding* it's basically depends on your layout file name. — Jay Rathod, Dec 23 '20 at 12:04
Error message: ```Unresolved reference: FragmentFastLoginBinding``` — 張聖坤, Dec 23 '20 at 12:06
I checked the suggestions, but I didn't find one about a similar layout file name. — 張聖坤, Dec 23 '20 at 12:09

If you followed every instruction of the link you just posted, Specially the setup instructions, you should be able to import ResultProfileBinding.

Keep in mind that this ********Binding class will have the same name of the layout file. Per example, if your layout file is my_own_layout.xml the binding class will be MyOwnLayoutBinding. In this particular case they called their layout file result_profile.xml

@jortas_mr.json My Android Version is 4.1.1. I had already added ```buildFeatures { viewBinding true }```in my build grade(app), but I think it was not changed at my project settings. – 張聖坤 Dec 24 '20 at 01:52
