Convert normal Java Array or ArrayList to Json Array in android

Question

Is there any way to convert a normal Java array or ArrayList to a Json Array in Android to pass the JSON object to a webservice?

Answer 1

Convert ArrayList to JsonArray : Like these [{"title":"value1"}, {"title":"value2"}]

Example below :

Model class having one param title and override toString method

class Model(
    var title: String,
    var id: Int = -1
){
    
    override fun toString(): String {
        return "{\"title\":\"$title\"}"
    }
}

create List of model class and print toString

var list: ArrayList()
list.add("value1")
list.add("value2")
Log.d(TAG, list.toString())

and Here is your output

[{"title":"value1"}, {"title":"value2"}]
