GSON. How to convert json object to json array?

Question

Now I am getting this JSON from API:

{\"supplyPrice\": {
        \"CAD\": 78,
        \"CHF\": 54600.78,
        \"USD\": 20735.52
      }}

But

Answer 1

You need to iterate all keys of supplyPrice object, and create New JSONArray using that key value then assign new array to supplyPrice key

JSONObject changeSupplyPrice(JSONObject JSONObj){
    try {
        JSONObject supplyPrice =JSONObj.getJSONObject("supplyPrice");
        JSONArray supplyPriceArray = new JSONArray();
        Iterator keys = supplyPrice.keys();

        while( keys.hasNext() ) {
            String key = (String)keys.next();
            Log.e("JSON Array key",key);
            supplyPriceArray.put(new JSONObject("{"+key+":"+supplyPrice.getString(key)+"}"));

        }
        JSONObj.put("supplyPrice", supplyPriceArray);
        return JSONObj;
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return null;
}

then call the function where you want

try {
        JSONObject JSONObj = new JSONObject("{'taxes': [],'name': 'Laboriosam iusto eum','requiresShipping': false,  'taxable': true,  'sku': 'QBA84J18832',  'product': 12, 'supplyPrice': {    'CAD': 78,   'CHF': 54600.78,    'USD': 20735.52  }}");
        JSONObj = changeSupplyPrice(JSONObj);
        Log.e("Return JSON Object",JSONObj.toString());
    } catch (JSONException e) {
        e.printStackTrace();
    }
