I am attempting to transform the JSON below into a list data object:
[
{
"type": "PHOTO",
"id": "pic1",
"title": "Photo 1",
"dataMap": {}
},
{
"type": "SINGLE_CHOICE",
"id": "choice1",
"title": "Photo 1 choice",
"dataMap": {
"options": [
"Good",
"OK",
"Bad"
]
}
},
---
---
]
code:
data class User(val type: String, val id: String, val title: String, val options: List<Options>)
data class Options(val dataMap: String)
fun getUserListFromAssert(context: Context, fileName: String) : List<User>{
val gson = Gson()
val listPersonType = object : TypeToken<List<User>>() {}.type
var users: List<User> = gson.fromJson(getJsonDataFromAsset(context, fileName), listPersonType)
return users;
}
Now call getUserListFromAssert:
var users: List<User> = TemporaryData.getUserListFromAssert(this, "users.json")
users.forEach { s -> Log.d(TAG, "onCreate: $s") }
Output:
User(type=PHOTO, id=pic1, title=Photo 1, options=null)

I am struggling to fetch a list of options from the JSON.
I attempted the code below and successfully retrieved options, but they are nested inside dataMap. Is it feasible to retrieve a list of options directly in the user class?
data class User(val type: String, val id: String, val title: String, @SerializedName("dataMap") val options: dataMap)
data class dataMap(val options: List<String>)
Output:
User(type=PHOTO, id=pic1, title=Photo 1, options=dataMap(options=null))
User(type=SINGLE_CHOICE, id=choice1, title=Photo 1 choice, options=dataMap(options=[Good, OK, Bad]))
