Accessing Local Variable In Lambda In Kotlin

I want to save data acquired from Volley, But lambda used in VolleyRequest function(which gets json data from server) blocks it. How should I change local variable that is in outsi

Solution 1:

Here the the code from were you are calling this method

getConData(this, "id") { condata ->

}

Now, your method look like this,

fun getConData(context: Context, idx : String, returnConData : (condata : ConDataforReturn) -> Unit){
        val params = HashMap<String,String>()
        var cd = arrayListOf<ConImgData>()
        var title =""
        params.put("package_idx",idx)
        Log.e("idx size",idx.length.toString())
        VolleyRequest(context,params,"https://dccon.dcinside.com/index/package_detail") { response ->
            val answer = JSONObject(response)
            var json = answer.getJSONArray("detail")

            title = answer.getJSONObject("info").getString("title")
            Log.d("title",title)//Prints right data
            for (i in 0..(json.length() - 1)) {
                val v = json.getJSONObject(i)
                cd.add(ConImgData(v.getString("title"), v.getString("ext"), v.getString("path")))
            }
            returnConData(ConDataforReturn(title,cd)) //returns ConDataforReturn("",arrayListOf<ConImgData>())
        }
    }
