How to disable smart cast highlight Kotlin?

Question

IDE : Android Studio 3.3

I am doing kotlin smart casting in RecyclerView adapter on ViewHolder.

override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
        holder as ViewHolder

Now every mention of viewholder is being highlighted, with text on hover saying "Smart Cast to ..." This is not a problem but really annoying. How can I disable this highlight feature?

Answer 1

In the IDE prefererences, see:

Editor → Color scheme → Kotlin → Smart-casts → Smart-cast value

If you want to disable value smart-cast highlighting, just uncheck Background.

You may want to configure the other kinds of smart-casts, too.

Answer 2

go to File -> Settings -> Editor -> Color Scheme -> Java/Kotlin -> Classes and Interfaces

You should be able to find color scheme for classes here. Hope it helps.
