Kotter Knife

Butter Knife-esque view binding for Kotlin.

public class PersonView(context: Context, attrs: AttributeSet?) : LinearLayout(context, attrs) {

val firstName: TextView by bindView(R.id.first_name)
val lastName: TextView by bindView(R.id.last_name)
 // Optional binding.
val details: TextView? by bindOptionalView(R.id.details)
 // List binding.
val nameViews: List<TextView> by bindViews(R.id.first_name, R.id.last_name)
 // List binding with optional items being omitted.
val nameViews: List<TextView> by bindOptionalViews(R.id.first_name, R.id.middle_name, R.id.last_name) 
}

These methods are available on subclasses of Activity, Dialog, ViewGroup, Fragment, the support library Fragment, and recycler view's ViewHolder.
