Butterknife: Don't work in kotlin

[hippyk]

I added the @JvmField annotation to the view, but it is still null after ButterKnife.bind(this).

@hippyk there's a kotlin implementation of Butterknife wirriten by Jake called kotterknife.

Please, check it out.

There's not enough information to make this report actionable. If you're having a problem the easiest way to get it resolved is by creating a standalone sample that demonstrates it in isolation. Otherwise it's impossible to know what you're doing.

@piotrek1543 Thank u! But My situation is special. There are too many codes to change if I use kotterknife instead.

@JakeWharton I found the "_ViewBinding" class for the kt class was not generated.

[JakeWharton]

Are you using kapt?

@JakeWharton No, but I'm using “kotlin-android-extensions”

[JakeWharton]

Without kapt Butter Knife will not work with Kotlin.

@JakeWharton Thank you very much！

I found another solution. Before converting the java file to kt, copy the method “xxxActivity_ViewBinding” that is generated and then add it to the kt file directly.

@hippyk That kind of defeats the purpose of this library as you now have to maintain the stuff yourself. Just use kapt, that's what it's meant for.
