You need to deserialize JSON to object, for deserialization you can use
com.google.gson add to gradle:
dependencies {
implementation 'com.google.code.gson:gson:2.9.1'
}
create your data class
data class Order(
val id:String,
val name:String,
val image: String,
#SerializedName("subcategory_id")
val subcategoryId: String,
#SerializedName("is_favorite")
val isFavorite: Boolean
)
and finally deserialize your incoming data from network
val responseFromNetwork = getDataFromNetwork() //here you get your json from network
val gson = Gson()
val ordersType = object : TypeToken<List<Order>>() {}.type
val itemList = gson.fromJson<List<Order>>(responseFromNetwork , ordersType)// will be deserialized only field what are in data class another one will be ignored
and finally add to DB your data

How to fetch data from a nested array?

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");

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:

for (int i = 0; i < menuArrayList.size(); i++) {
result1111 = new ArrayList<ExpanTitelandTotal>();

My question is: how do I access the next question of "questions" when i click next for the next question since "58242", "58245", etc are all dynamic values?
the answer on this post was very helpfull but now i want to now how loop through the questions How to parse a dynamic JSON key in a Nested JSON result
it helped me get the currentdynamic value but does not give me the next question when i click on next
private View.OnClickListener nextListener = new View.OnClickListener() {
public void onClick(View v) {
setAnswer();
try {
if (quesIndex != searchResult.getJSONObject("questions").length() - 1) {
quesIndex++;
progress.setProgress(0);
progress.setMax(100);
} else {
Intent myIntent = new Intent(TestActivity.this, Assesment.class);
myIntent.putExtra("intVariableName", score);
startActivity(myIntent);
}
} catch (JSONException e) {
e.printStackTrace();
}
try {
if (quesIndex == searchResult.getJSONObject("questions").length() - 1) {
next.setText("Finish");
Intent myIntent = new Intent(TestActivity.this, Assesment.class);
myIntent.putExtra("intVariableName", score);
startActivity(myIntent);
// close this activity
finish();
}
} catch (JSONException e) {
e.printStackTrace();
}
showQuestion(quesIndex, review);
}
};
will appreciate the help thanks :)

Not sure what you problem is. Seems like the solution is in the link you gave above.
JSONObject questions = result.getJSONObject("questions");
Iterator keys = questions.keys();
//go through every question
while (keys.hasNext()) {
String currentDynamicKey = (String)keys.next();
JSONObject currentQuestion = questions.getJSONObject(currentDynamicKey);
}

JSONObject jsonResult = new JSONObject(jsonUser);
JSONArray data = jsonResult.getJSONArray("education");
if(data != null)
{
for(int i = 0 ; i < data.length() ; i++)
{
JSONObject c = data.getJSONObject(i);
String type = c.getString("type");
if(type.equalsIgnoreCase("college"))
{
JSONObject school = c.getJSONObject("school");

String name2 = school.getString("name");
JSONObject year = c.getJSONObject("year");
String id_y = school.getString("id");
String name_y = school.getString("name");
}
}
}

Supposing that you've this json into a jsonObject that you retrieve as response, this is the way:
// Get jsonArray 'education' from main jsonObject
JSONArray jsonArrayEducation = jsonObject.getJSONArray("education");
JSONObject jsonSchool = jsonArrayEducation.getJSONObject("school");
Note that if you are interested only at the name, you can group the two lines above into
JSONObject jsonSchool = jsonObject.getJSONArray("education").getJSONObject("school");
// get school name
String schoolName = jsonSchool.getString("name");
