How does multiple assignment work is Kotlin?

int mBaseSystemUiVisibility = SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | SYSTEM_UI_FLAG_LAYOUT_STABLE;

UserModel.Creator(
_, foo, bar, cat, moo, _ -> User(foo, bar, cat, moo)
)

works fine, but

UserModel.Creator(
_, foo, bar, cat, moo, _ -> {
Log.d("")
User(foo, bar, cat, moo)
}
)

doesn’t work.

How do I "enable multiplatform projects explicitly"? I get the error message "Kotlin: The feature "multi platform projects" is experimental and should be enabled explicitly" on every expected/actual declaration in my project. The project works perfectly fine on my other computer, where I created the project with the IntelliJ wizard. On my new computer I get this error message when I build in IntelliJ, however gradle over CLI builds without errors

how can I turn two arrays into a map whose keys are from one array and values are from the other?

No, the property could change, because it is mutable. Store it in a local variable, then do the nullcheck and access with that local variable.

you can't recursively call an inline function. How would it inline the recursive calls?

Oh I see, thanks for the input, it just needs a level of un-inlining, right?

so use

x as? y != null

ah ok, thanks, was confused because

job.isCompleted

returns true after

cancel()

It's a prepend list which is more idiomatic for functional programming, e.g. separating head and tail in recursive functions: https://alvinalexander.com/scala/how-to-use-lists-nil-cons-scala-match-case-expressions

I'm getting a type mismatch error trying to spread an array of Ints. Am I'm doing something wrong, or is this a type inference limitation or bug?

fun main(args: Array<String>) {
	val ints = arrayOf(1, 2, 3)
	// Type mismatch: inferred type is Array<Int> but IntArray was expected?
	spreadTest(*ints)
}

fun spreadTest(vararg ints: Int) {
	for (int in ints) {
		println(int)
	}
}

I need to try a change in the local copy of Kotlin compiler source code. So I need to debug the new change. But I see it is not reflected as it is still using the installed version of compiler not the changed version. Can you please advice how to achieve that?

what’s the error message if you don’t change to

Any

?

What’s the filter doing? There might be a faster way to do it.

not sure what kind of api you’re working with, but if you can’t expect a given object to be shaped the same way each time you request it, I feel like you have bigger problems

what part are you stuck on specifically?

You can also create an array directly:

Array((2018 - 1960 + 1), { i -> (i + 1960).toString() })

I’m new to this community, I wanted to learn Kotlin, especially focusing on Android Development. Where can I start?

anyone's got an android project in kotlin with mutli activities? like switching them on click or something and has a source on github?

It's clear as hell in Java 🙂 - This is a porting excercise - rethinking the code is out-of-scope. Let me hack on this a bit more

@adam-mcneilly that’s odd, I just pasted that into my editor and it’s not complaining

hey, why is this happening? http://snpy.in/2eRFRN

ok here we go, link works now, why is this happening? http://snpy.in/GzpxU4 it’s when I launch my first command in the kotlin interpreter

Hi, I'm writting my first annotation processor in Kotlin. I need to check the type of a annotated property in order to know if is optional or not. I have something like @MyAnnotation var property: String? But I don't know if it can be done. I have an instance of Element class from javax.lang.model.element packpage in my annotation processor. I can do element.asType() to get the type of my property, but I don't know how to check if this property is optional or not.

even simple lang like Go can do it ^^

enum valueOf method Am I able to modify the behavior of an enum’s

valueOf

? Or will it only ever consider the

name

property on the specified enum?

From what I read the .then(...) there is an extension function, right? What is the reason it was put there as such instead of inside the Filter interface as a member with implementation?
