Just looking for the shortest way of implementing Parcelable

Question

Just looking for the shortest way of implementing Parcelable and I found Parcelize so I need help in converting my data class into parcelable data classes `data class SiteResponse SerializedName result val result String SerializedName freason val freason String SerializedName site val siteList ArrayList lt SiteObject gt inner class SiteObject SerializedName name val name String SerializedName short name val shortName String SerializedName id val id Int SerializedName country id val countryId Int SerializedName region id val regionId Int SerializedName province id val provinceId Int SerializedName city id val cityId Int SerializedName latitude val latitude String SerializedName longitude val longitude String `

gildor · Answer

use backticks for your `code snippets`

gildor · Answer

``` triple ones in this case ```

gildor · Answer

As I understand Parcelaize requires to implement Parcelable in both of those classes Also you don t need `inner` here and you can make nested class data as well

gildor · Answer

So what is you problem to use Parcelize here

sqia09 · Answer

because my own implementation is not working

gildor · Answer

please show your implementation and error that you have

sqia09 · Answer

parcelize is the shortest way but I want to know if it has been successfully used as it s in experimental phase

gildor · Answer

Parcelize works but yeah it s experimental so up to you

sqia09 · Answer

I need to fix these then I ll move onto the SiteResponse and SiteObject

sqia09 · Answer

will it work for this kind of model in harmony with Gson SerializedName annotation

gildor · Answer

annotations will be just ignored

gildor · Answer

Really I want to help but you should figure out what kind help do you need

sqia09 · Answer

I need to get rid of that illegalstateexception source readString must not be null

budioktaviyan · Answer

If you are updating to the latest kotlin version 1 1 4 3 Parcelize already works even if you have the `annotationProcessor` inside your code But lint checking are still annoying ^^

gildor · Answer

< sqia09> I already pointed you in ahother thread that probably you use deserialization of List in wrong way Your Parcelable looks good so it s not a problem in implementation of Parcelable itself

sqia09 · Answer

ok then I m retrieving the array the wrong way

sqia09 · Answer

i ll try something else

gildor · Answer

You can sure that your parcelable is correct of you send only one object instead of list

gildor · Answer

Also you showed my example of another class that has two list inside if you want to send RouteSite list it s easy just create an Intent and put your list `Intent putParcelableArrayListExtra ArrayList listOfRouteSite ` then use getParcelableArrayListExtra

gildor · Answer

but if you have more complex example it s just hard to me figureout what s going on there

sqia09 · Answer

ok thanks

sqia09 · Answer

thanks solved it i had to give default values for Ints and added in string fields

sqia09 · Answer

It looks like I was getting null for some fields from the webservice

sqia09 · Answer

and used the above mentioned code for passing the array

sqia09 · Answer

thanks again
