android - Kotlin by Lazy in Custom Views -


currently, using by lazy in custom view break visualisation in android studio. using iseditmode can't used because available inside method , not @ variable initialisation scope. workaround using lateinit , or delegates.notnull().

is there workaround this?

example:

class imageviewcirclebg : imageview {      private var circlebgcolor = r.color.colorprimary     private val paint lazy {         paint().apply {             style = paint.style.fill             isantialias = true         }     }      constructor(context: context) : this(context, null)     constructor(context: context, attrs: attributeset?) : this(context, attrs, 0)     constructor(context: context, attrs: attributeset?, defstyleattr: int) : super(context, attrs, defstyleattr) {          val ta = context.theme.obtainstyledattributes(attrs, r.styleable.imageviewcirclebg, 0, 0)         circlebgcolor = ta.getcolor(r.styleable.imageviewcirclebg_roundbgcolor, circlebgcolor)         ta.recycle()          this.paint.color = circlebgcolor     }

produces following error in android studio design window:

the following classes not instantiated: - ....imageviewcirclebg (open class, show exception, clear cache)  tip: use view.isineditmode() in custom views skip code or show sample data when shown in ide  exception details java.lang.incompatibleclasschangeerror: found class kotlin.lazy, interface expected   at ...imageviewcirclebg.getpaint(imageviewcirclebg.kt:-1)

replacing lazy this:

private val paint: paint      init {         paint = paint().apply {             style = paint.style.fill             isantialias = true         }     }

solves problem.

error:

java.lang.incompatibleclasschangeerror: found class kotlin.lazy, interface expected
