Kotlin으로 Custom View 만들기

class InitView @JvmOverloads constructor(
        context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : LinearLayout(context, attrs, defStyleAttr){
    init {
        val inflater: LayoutInflater = getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        val view = inflater.inflate(R.layout.view_main, this, false)
        addView(view)
        
        // 로직
    }
}
