I have a jsonArray object like the "Input" below. I would like the "Output". Could you help me ?
Input :
"["a", "b", "c", "d"]"
Output :
["a", "b", "c", "d"]
//i need a simple list of string
I have found a solution but it's too complex for a simple conversion....
val errorFields = jsonResponse.getJSONArray("my_array")
.join(",")
.replace("\"", "")
.split(",")
By manual parsing you can get a list of string from jsonArray by -
val list = ArrayList<String>()
repeat(jsonArray.length){
list.add(jsonArray.getString(it))
}
If you are using parsing library gson than you can get a list of strings by -
val list = gson.fromJson(jsonArray.toString(), Array<String>::class.java)?.toList()
You could do it like so:
val stringList : MutableList<String> = arrayListOf()
jsonArray?.let {
for (i in 0 until it.length()) {
stringList.add(jsonArray.getString(i))
}
You can do this way in Koltin
var str = "[\"a\", \"b\", \"c\", \"d\"]"
var items = Arrays.asList(str?.split("\\s*,\\s*")).flatten()
flatten is needed as it returns a list of lists.
