I've added core-ktx to my gradle but toast extension function is unresolved what am I missing?

hello i was wondering is it in the Kotlin plan to do something abut creating UI in android and replacing XML base UI with something sweeter and more flexible for example if you have played with flutter in android you will notice it is a amazing language for creating awesome UI ?

guys, can you help me? this is my first trying this in Kotlin. I have a function where i need to use the result from the function in this screenshot, why its gonna jump to line 201 after line 189? Why its not run what inside result.failure or result.success first? edit : because of that what i got is empty string when call this function from other function.

I have my class

data class (var name:String, surname:String)

how can i know prop name and value ? I don't want use reflection and "java" Fields

Does anyone know how to set kotlin compiler args in gradle?

Are dashes no longer allowed in Intellij module names? I am getting an error trying to add a new one with a dash, although all my previous modules have dashes in the name

Does anyone know if there is a an Intellij inspection or a lint rule that can mark dependencies as unused?

class SomeActivity @Inject constructor() {
    @Inject
    lateinit var notUsed: UnusedClass
}

Over the years, classes have built up with unused dagger classes

@Inject

properties . It’s hard to clean this up manually over an entire codebase.

Quick quesiton, so

findViewById

is no longer necessary,

val btnSaveClick= findViewById<Button>(R.id.btnSave)
      btnSaveClick?.setOnClickListener {
          Toast.makeText(this@ArticleAdapter, "Article saved.", Toast.LENGTH_LONG).show()
      }

What should be used instead. I have this in my activity.xml:

<Button
            android:id="@+id/btnSave"
            android:layout_width="70dp"
            android:layout_height="40dp"
            android:onClick="btnSave"
            android:text="@string/save"
            android:textAlignment="center" />

Is it safe to change from

Is there an adapter for Retrofit that can generate sealed classes from error codes?

if I use Parcelize annotation, I get an error while compiling, saying I am not implementing the abstract methods, is this supposed to be like that or a bug?

Any tricks that you maybe use to hide this long ass styleable ids in your custom classes?

a private field with a map of short aliases for this attrs?

I’m getting an unresolved reference error on

setOnClickListener

within an adapter class I have, can’t seem to figure out why

val formatter = SimpleDateFormat("yyyy-MM-dd HH:mm:ssZ", Locale.getDefault())
formatter.timeZone = TimeZone.getTimeZone("UTC")
val result = formatter.parse(dateTv.text)

Would this work?

Hello please help.How do I fix it ? Thanks ?/AS 3.4,Gradle 5,JAVA 11/

Hi guys, if you have any issues when you are migrating to AndroidX, (remember that XMLs crash in runtime), you could use this linux command:

grep -rnw '.' -e 'android.support'

It returns each ocurrency, with the file and the line

./layout/activity_new_incident.xml:33:    <android.support.design.widget.FloatingActionButton

(edited) I don't know if we can improve the command, moving into a script (in order to add it to CI or whatever) If anyone have any suggestions, feel free to post any updates -> https://gist.github.com/sergiocasero/fab62dfbeb303b49c1991b909cb3cf19 PD: I know this is an easy command, it just for sharing 🙂

I have a problem with Kotlin enums and Moshi. It seems like when I annotate an enum member with

@Json(name = "xx")

, the serialized string has the name of the enum member itself instead of the value passed into the annotation. Has anyone run into this problem before?

I sometimes get null from "Kotlin android extensions synthetic binding" although the view is created and in resumed state. Weird thing is if I access the binding in

onViewCreated

with an empty

apply

the binding works properly. Here is a question I asked on stackoverflow when I first encountered the issue https://stackoverflow.com/questions/48971322/kotlin-android-extension-fragment-view-null Has anyone else experieced this issue?

Here is the project I'm currently working on and has this issue. https://github.com/saied89/FilmCompass
