I have following JSON String.
{
"data": [
{
"city_id": "1",
"city_name_eng": "Multan",
"0": {
"category_id": "1",
"city_id": "1",
"category_name_eng": "Mango",
"0": {
"product_id": "1",
"category_id": "1",
"product_name_eng": "Mango1"
},
"1": {
"product_id": "2",
"category_id": "1",
"product_name_eng": "Mango2"
},
"2": {
"product_id": "3",
"category_id": "1",
"product_name_eng": "Mango3"
},
"3": {
"product_id": "4",
"category_id": "1",
"product_name_eng": "Mango1"
}
},
"1": {
"category_id": "2",
"city_id": "1",
"category_name_eng": "Shoes"
},
"2": {
"category_id": "3",
"city_id": "1",
"category_name_eng": "Bank"
}
},
{
"city_id": "2",
"city_name_eng": "Lahore",
"3": {
"category_id": "4",
"city_id": "2",
"category_name_eng": "Food"
},
"4": {
"category_id": "5",
"city_id": "2",
"category_name_eng": "Computer"
},
"5": {
"category_id": "6",
"city_id": "2",
"category_name_eng": "Mobile"
}
}
]
}
I want to have length of JSONObject. Basically, the first object having "city_id": "1" has 4 nested JSONObjects and 2 values, i.e. city_id and city_name_eng.
When i use objJSON.length() , it gives me length of 6. But on the contrary I want to have 4 nested JSONObjects, how can i get it on run-time? (whether the nested jsonobjects are 3 or 4 or any number)
How to differentiate between nested JSONObjects and key values?
If the website is your own, then I suggest reworking the code to return JSONArrays where appropriate.
Otherwise, jsonObj.keys() will return an Iterator which you an use to iterate over the keys and parse out your objects.

Please give me any solution to parse this and show like this below image example recycler tree structure. This is purely dynamic adding folders and response also changed every time.
I have to fetch the value from an array nested inside another array. I can fetch values from the first array but not able to fetch values from the second array.
I am able to read the values from the main array but I am unable to read the values from the array which is nested inside it.
JSONObject jsono = new JSONObject(res);
JSONArray jarray = jsono.getJSONArray("data");
for (int i = 0; i < jarray.length(); i++)
{
JSONObject object = jarray.getJSONObject(i);
JSONArray jarray1 = object.getJSONArray("comments_data");
for (int j = 0; j < jarray1.length(); j++)
{
JSONObject object1 = jarray1.getJSONObject(j);
String Namee = object1.getString("username");
String Ratingg = object1.getString("rating");
String Commentt = object1.getString("comment");
Comments comments1 = new Comments();
comments1.setUsername(Namee);
comments1.setRating(Ratingg);
comments1.setComments(Commentt);
comments1.setProfileimage(R.drawable.fav);
commentsList.add(comments1);
}
}
And this is my json.

Note carefully how you JSON is built.
First, you have to query for "data". You get JSON-Array. So you traverse it by the indices.
Hence, you query for the specific index in "data" (you can use a loop, of course).
For each iteration, you get a JSONObject, and in it you query for "comments_data".
String json = "{ \"status\": \"success\", \"msg\": \" Menu Details\", \"data\": [ { \"id\": \"1\", \"rest_id\": \"1\", \"menu_rate\": \"100\", \"collection_time\": \"2:22pm\", \"quantity_left\": \"3\", \"food_type\": \"veg\", ...
JSONObject object = new JSONObject(json);
JSONObject jarray1 = jarray_data.getJSONObject(0);
JSONArray comments = jarray1.getJSONArray("comments_data");
I want to know how to filter data. I got data with category name but cannot filter category wise.Here is my data:
{
"TITLE": "tea",
"PRICE": "17",
"QTY": "1",
"CAT_ID": "33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg"
},
{
"TITLE": "Coffee",
"PRICE": "102",
"QTY": "1 ",
"CAT_ID": "8",
"CAT_NAME": "MORNING SPECIAL",
"TYPE": "veg"
},
{
"TITLE": "Jeera chachh",
"PRICE": "42",
"QTY": "1",
"CAT_ID": "33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg"
},
{
"TITLE": "Roti Ghee Wali",
"PRICE": "21",
"QTY": "1",
"CAT_ID": "33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg"
},
{
"TITLE": "Paneer paratha",
"PRICE": "102",
"QTY": "1 ",
"CAT_ID": "8",
"CAT_NAME": "MORNING SPECIAL",
"TYPE": "veg"
},
{
"TITLE": "Mix paratha",
"PRICE": "102",
"QTY": "1",
"CAT_ID": "8",
"CAT_NAME": "MORNING SPECIAL",
"TYPE": "veg"
},
I already parse the data but not able to set in fragment according to category.Can anyone solve my issue.
Step 1: Store the data in database.
Step 2: Search
select * from table where CAT_NAME = 'your_filter_category'.
or better ....CAT_NAME like %your_filter_category%.
In Case of no database;
Store the Data in list.
HashMap<String, ArrayList<Item>> map = new HashMap<>();
ArrayList<Item> itemList = new ArrayList<>();
Loop on List{
Item item = fromLoop index;
if(map.contains(item.getCat())){
itemList = map.get(item.getCat());
itemList.put(item);
map.put(item.getCat(),itemList);
}else{
itemList.clear();
itemList.put(item);
map.put(item.getCat(),itemList);
}
}
//after loop you will get HashMap with keys as categories and Values as the list of selected key category.
Step 3: Publish the results.
Note: No one will do your homework here. the only thing we can do for you, we can assist you how to do.
enter your code to: JSON Formatter and you will see that something is invalid in your JSON, it has multiple root elements. Maybe you should store whole code in JSONArray like this: `
{
"features":
[{
"TITLE": "tea",
"PRICE": "17",
"QTY": "1",
"CAT_ID":"33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg" },
{
"TITLE":"Coffee",
"PRICE": "102",
"QTY": "1 ",
"CAT_ID": "8",
"CAT_NAME":"MORNING SPECIAL",
"TYPE": "veg"
}]
}

above is my code and when i run this i get following output
In expandable list view two different category data store in all main category data ? any idea how can i solve this ?
Create a new List object inside the first for loop sentence:
List<ExpanTitelandTotal> result1111;
for (int i = 0; i < menuArrayList.size(); i++) {
result1111 = new ArrayList<ExpanTitelandTotal>();
/////YOUR CODE
