QUESTION
I'm new in Android dev. And I was faced with the fact that I need to redo my class into Parcelable class. And the main problem with it is that i have 3 nested classes into my class.
It is my code:
...ANSWER
Answered 2020-Mar-23 at 10:20No need to do all that. Just use @Parcelize
from Kotlin.
Annotate all theses classes with @Parcelize
and make them extend Parcelable
. You can remove all your Parcelable
related code in the Test
class.
Also I'll recommend modifications for a few things wrong that I see in your code :
- Turn all your
var
properties toval
. It will enforce immutability, one of Kotlin's basic features. The same goes for yourArrayList
s, useList
instead to disallow modifications of the list. If you really can't have a read-onlyList
then useMutableList
. It's more easy to understand that it's a read/write list than when you useArrayList
. - Make your
Test
class adata class
. I don't see why not benefit from it in your case. - All classes name must begin with an uppercase.
multipleChoiceAnswers
->MultipleChoiceAnswers
. It's a convention we follow in many languages, not just Kotlin.
QUESTION
I made html template for my app. Basically it's a radio/checkboxes with text inputs which contain answers to questions. It worked just fine until I've decided to add ngModel to them. The thing is that when I add 2 or more answers and click on a label to set the correct one(/s) only the last one selects, moreover the answertext disappears whenever I click on label.
html text:

having multiple input with the same name is definitive wrong here. Try name="customCheckbox{{i}}"
. When using ngModel you need a name that identifies the form control. It has to be unique

To start with, my state is set up in the App component as follow:
...ANSWER
Answered 2019-Apr-20 at 13:11You should not keep the components inside the state (cause that breaks the components lifecycle and it is hard to compare them). Instead, just keep the keys:
