How to iterate over a JSONObject?

Question

I use a JSON library called JSONObject (I don\'t mind switching if I need to).

I know how to iterate over JSONArrays, but when I parse JSO

Answer 1

I made my small method to log JsonObject fields, and get some stings. See if it can be usefull.

object JsonParser {

val TAG = "JsonParser"
 /**
 * parse json object
 * @param objJson
 * @return  Map
 * @throws JSONException
 */
@Throws(JSONException::class)
fun parseJson(objJson: Any?): Map {
    val map = HashMap()

    // If obj is a json array
    if (objJson is JSONArray) {
        for (i in 0 until objJson.length()) {
            parseJson(objJson[i])
        }
    } else if (objJson is JSONObject) {
        val it: Iterator<*> = objJson.keys()
        while (it.hasNext()) {
            val key = it.next().toString()
            // If you get an array
            when (val jobject = objJson[key]) {
                is JSONArray -> {
                    Log.e(TAG, " JSONArray: $jobject")
                    parseJson(jobject)
                }
                is JSONObject -> {
                    Log.e(TAG, " JSONObject: $jobject")
                    parseJson(jobject)
                }
                else -> {
                    Log.e(TAG, " adding to map: $key $jobject")
                    map[key] = jobject.toString()
                }
            }
        }
    }
    return map
}
}
