Android: Kotlin with Butterknife

Question

I\'m trying to use Kotlin with Butterknife for my Android Application.

Here is my build.gradle

dependencies {
    ...
    compile \'com.jakewharton:b         


        

Answer 1

In your app level build.gradle

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-kapt'

kapt {
    generateStubs = true
}

dependencies {
    compile 'com.jakewharton:butterknife:10.2.0'
    kapt 'com.jakewharton:butterknife-compiler:10.2.0'
}

In your Top Level build.gradle

buildscript {
    ext.kotlin_version = '1.3.30'
    repositories {
        jcenter()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

Activity

@BindView(R.id.toolbar)  @JvmField var toolbar: Toolbar? = null

or

@BindView(R.id.toolbar) lateinit var toolbar: Toolbar

Inside OnCreate

ButterKnife.bind(this)
