but I am a bit confused about what my

BaseFragment

should extend, and I'm not 100% sure this is a good idea to begin with. I end up duplicating that code across all fragments and sometimes will forget to write it, so I was thinking having it in one place might be nice

or if there's a cleaner way to abstract out this logic

katien

abstract class BaseFragment : Fragment(), BaseView<BasePresenter<BaseFragment>> {

I don't think this is right though...

I'm still a bit new to these concepts but am thinking maybe I can figure out a way to refactor this to be done with composition instead of inheritance. Not totally sure what that would look like though, since I need access to the fragment lifecycle callbacks

Copy code

interface BasePresenter<T> {
    var view: T?

    fun attachView(view: T) { this.view = view}
    fun detachView()  { this.view = null}
}

so, to represent error responses with a format like this:

Copy code

{
  "errors": {
    "first_name": [
      "first name is required"
    ],
    "last_name": [
      "last name is required"
    ],
    "image": [
      "Invalid image format"
    ]
  },
  "message": "Invalid profile data",
  "status": 400
}

I parse my json into this response model:

Copy code

data class ErrorResponse (
        var errors: Map<String, List<String>> = emptyMap(),
        var status: Int = 0) {
    operator fun get(k: String): List<String>? = errors[k]
}

Context (the Kotlin question comes at the end): I'm building a basic finance tracking app. I have a dialog fragment that is used to enter a transaction for the account. I use a new instance method that takes in the account name and puts it in the bundle and life is good I can reference it in

onCreate()

. Now I want to expand this same dialog fragment to be used for adding or editing a transaction. In my head I see two options: a separate new instance method that takes in the transaction to be edited and I use some flag to determine the state of the dialog. Is there some way to use sealed classes for this, though? I could have like

sealed class TransactionState

with a class for add and edit, but it doesn't look like sealed classes can be parcelable, so idk if what I'm asking is feasible but would love for someone to put my mind at rest about it.

I'm struggling to find out how to listen for collapse/expand events on a collapsing toolbar layout on both the

CollapsingToolbarLayout

docs and stackoverflow. Can anyone point me in the right direction?

I’m not sure if this is a Kotlin question, an Android question, or a Retrofit question but here goes,

Copy code

class GetCoordinatesApiManager: Callback<LocationResult> {

    var completionHandler: (flag:Boolean) -> Unit = {}

    fun getCoordinates(userIds: ArrayList<Int>, handler: (flag: Boolean) -> Unit) {
        completionHandler = handler
        ApiClient.apiInterface.getCoordinates(userIds, UserState.bearerToken!!).enqueue(this)
    }

Android Studio complains that

this

enqueue(this)

Type Mismatch Required: Callback <LocationResult!>! Found: GetCoordinatesApiManager

once you set it to

bubble

you should it use that instead of advancing the iterator again

menegatti

12/27/2017, 10:30 AM

their sequence is based on an iterator… so I’m not sure why it wouldn’t work

menegatti

12/27/2017, 10:43 AM

let me know if it works 😄

Can anyone point me to an official statement about whether KDoc or Dokka is the way to document Kotlin files going forward? My manager doesn’t want us to invest in one, only to have to switch to another.

bradfordholcombe

Dokka has a very different approach to documenting. It prefers references inline with the description using brackets. See for example yole’s answer in https://stackoverflow.com/questions/28527838/kotlin-kdoc-documentation which says that the old “tags are available and supported, but not recommended for use”
