Suppose I have a kotlin interface with var background: Drawable and I want to create a Kotlin class implementing this interface and extending a java class that already defines setBackground(Drawable) and Drawable getBackground(). In Java, I don't need to do anything because the new subclass automatically implements these interface methods. In Kotlin, I get a compile error that the new subclass does not implement those interface methods. How to achieve this?

Unfortunately right now you will not be able to both extend the Java class and directly implement the interface from Kotlin.

As a work-around, you could move the interface to Java, maybe.

But I have not tried that.

Thanks, I'm also looking at this: https://stackoverflow.com/a/44035461/444761

You could maybe use @JvmName on the interface, but I am not sure if that works.

For the moment, I'll just refactor the interface vars to getDrawable/setDrawable funs

I think that works...

It should, but you loose the nice property syntax.
