Making JSON in android

Question

I need to make JSON like this on android -

{
 "Warp":[
 {
 "Type":"Cotton",
 "Property":"Carded",
 "Count":"10"
 },
 {
 "Type":"Cotton",
 "Property":"Carded",
 "Count":"10"
 }
 ]
}

I tried

j = new JSONObject();
j2.put("Type", "Cotton");
j2.put("Property", "Carded");
j2.put("Count", "10");
a = new JSONArray();
a.put("Warp", j2);

But looks like I cannot directly put an JSONArray inside a JSONObject like this.

Any help is appreciated.

Answer 1

Do Something like this :

try {
 JSONObject mainObject = new JSONObject();
 JSONArray array = new JSONArray();
 JSONObject object1 = new JSONObject();
 JSONObject object2 = new JSONObject();
 object1.put("Type", "Cotton");
 object1.put("Property", "Carded");
 object1.put("Count", "10");
 object2.put("Type", "Cotton");
 object2.put("Property", "Carded");
 object2.put("Count", "10");
 array.put(object1);
 array.put(object2);
 mainObject.put("Warp", array);
 } catch (JSONException e){
 e.printStackTrace();
 }

Answer 2

Do it like this:

// Create object
JSONObject objectInArray = new JSONObject();
objectInArray.put("Type", "Cotton");
objectInArray.put("Property", "Carded");
objectInArray.put("Count", "10");
// Create array and add the object
JSONArray array = new JSONArray();
array.put(objectInArray);
// Create the object and add the array on "wrap"
JSONObject wrapObject = new JSONObject();
wrapObject.put("wrap", array);

Answer 3

try this

j = new JSONObject();
 j2.put("Type", "Cotton");
 j2.put("Property", "Carded");
 j2.put("Count", "10");
 a = new JSONArray();
 a.put(j2);
 j.put(a);

Answer 4

you cannot put JsonObject with key inside JsonArray, JsonArray will hold all JsonObject without key.

JSONArray warpArray=new JSONArray();
JSONObject inner=new JSONObject();
inner.put("Type", "Cotton");
inner.put("Property", "Carded");
inner.put("Count", "10");
warpArray.put(inner);
JSONObject mainJson=new JSONObject();
mainJson.put("Warp",warpArray);

Answer 5

 public JSONObject createGroupInServer() throws JSONException {
 JSONObject jResult = new JSONObject();
 JSONArray jArray = new JSONArray();
 for (int i = 0; i < ArrayList.size(); i++) {
 JSONObject jGroup = new JSONObject();
 jGroup .put("Type", "Cotton");
 jGroup .put("Property", "Carded");
 jGroup .put("Count", "10");
 jArray.put(jGroup);
 }
 jResult.put("Warp", jArray);
 return jResult;
}

Answer 6

You can use easily like this

try {
 JSONObject root = new JSONObject();
 JSONArray wrap = new JSONArray();
 for (int i = 0; i < 2; i++) {
 JSONObject wrapObj = new JSONObject();
 wrapObj.put("Count", "10");
 wrapObj.put("Property", "Carded");
 wrapObj.put("Type", "Cotton");
 wrap.put(wrapObj);
 }
 root.put("Warp", wrap);
 } catch (JSONException e) {
 e.printStackTrace();
 }

Don't forgot to put your code in try-catch block.
