I googled a lot today for this subject. But I can't find it, How can I add a JSONArray to a JSONObject?
Because everytime I do this I get this error: Stackoverflow
JSONObject fillBadkamerFormaatFromContentlet(Structure structure, String formaat) {
JSONObject jsonObject = new JSONObject();
JSONArray arr = new JSONArray();
BadkamerFormaat badkamerFormaat = new BadkamerFormaat();
BadkamerTegel badkamerTegel;
List<Contentlet> contentlets = getContentletsByStructure(structure);
badkamerFormaat.formaat = formaat;
badkamerFormaat.tegels = new ArrayList<BadkamerTegel>();
try {
jsonObject.put("formaat", formaat);
} catch (JSONException e1) {
throw new RuntimeException(e1);
}
for(Contentlet contentlet : contentlets) {
badkamerTegel = new BadkamerTegel();
badkamerTegel.naam = contentlet.getStringProperty(ParameterNames.toolBetegelVeldNaam);
try {
badkamerTegel.afbeeldingTegel = contentlet.getBinary(ParameterNames.toolBetegelVeldTegelAfbeelding).getPath();
badkamerTegel.afbeeldingBadkamer = contentlet.getBinary(ParameterNames.toolBetegelVeldBadkamerAfbeelding).getCanonicalPath();
arr.put(badkamerTegel.toJSON());
} catch (IOException e) {
throw new RuntimeException(e);
}
}
try {
jsonObject.put("aoColumnDefs",arr);
} catch (JSONException e) {
throw new RuntimeException(e);
}
return jsonObject;
}
I get this error:

The JSON I want: Only the last JsonArray is going wrong:
{
"wand": [
{
formaat: 'vierkant15x15'
tegels: [
{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
]
}
,
{
formaat: 'vierkant17x15'
tegels: [
{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
]
}
]
, "vloer": [ { formaat: 'vierkant10x15' tegels: [ {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'} ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'} ] } ,
{
formaat: 'vierkant45x15'
tegels: [
{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
]
}
]
}
I'm starting to learn about this myself, being very new to android development and I found this video very helpful.
https://www.youtube.com/watch?v=qcotbMLjlA4
It specifically covers to to get JSONArray to JSONObject at 19:30 in the video.
Code from the video for JSONArray to JSONObject:
JSONArray queryArray = quoteJSONObject.names();
ArrayList<String> list = new ArrayList<String>();
for(int i = 0; i < queryArray.length(); i++){
list.add(queryArray.getString(i));
}
for(String item : list){
Log.v("JSON ARRAY ITEMS ", item);
}
Your list:
List<MyCustomObject> myCustomObjectList;
Your JSONArray:
// Don't need to loop through it. JSONArray constructor do it for you.
new JSONArray(myCustomObjectList)
Your response:
return new JSONObject().put("yourCustomKey", new JSONArray(myCustomObjectList));
Your post/put http body request would be like this:
{
"yourCustomKey: [
{
"myCustomObjectProperty": 1
},
{
"myCustomObjectProperty": 2
}
]
}
Just try below a simple solution:
JsonObject body=new JsonObject();
body.add("orders", (JsonElement) orders);
whenever my JSON request is like:
{
"role": "RT",
"orders": [
{
"order_id": "ORDER201908aPq9Gs",
"cart_id": 164444,
"affiliate_id": 0,
"orm_order_status": 9,
"status_comments": "IC DUE - Auto moved to Instruction Call Due after 48hrs",
"status_date": "2020-04-15",
}
]
}
here is simple code
List <String> list = new ArrayList <String>();
list.add("a");
list.add("b");
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
array.put(list.get(i));
}
JSONObject obj = new JSONObject();
try {
obj.put("result", array);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
pw.write(obj.toString());
