I've been trying to parse the objects from this object that is inside an array inside another array. I made two loops because there are multiple objects that i'm trying to make a list from.
This is what the json looks like

I just need the place, magnitude and time from both arrays but i can't seem to pick the right array to get the object from. ex:(features.properties.place)
List<String> allPlaces = new ArrayList<>();
JSONArray JA = new JSONArray(data);
JSONArray features = JA.getJSONArray(2);
// JSONArray properties = features.getJSONArray(1);
for (int i = 0; i < features.length(); i++){
JSONArray properties = (JSONArray) features.get(i);
for (int j = 0; j < properties.length(); j++){
JSONObject JO = (JSONObject) features.get(i);
String place = JO.getString("place");
singlePlace = "place: " + place;
dataPlace = "" + singlePlace;
allPlaces.add(place);
}
edit1: to be clear, i am able to get information from the first array, so the value of type, but not anything inside of features,
A problem is that you are parsing the properties as a JSONArray but in fact it's a JSONObject. So, you should try this loop to parse needed data:
JSONObject root = new JSONObject(data); //Where `data` is your raw json string
JSONArray features = root.getJSONArray("features");
for (int i = 0; i < features.length(); i++) {
JSONObject properties = features.getJSONObject(i).getJSONObject("properties");
double mag = properties.getDouble("mag");
String place = properties.getString("place");
long time = properties.getLong("time");
}

I am really new to JSON Parsing and learning everyday.
I have a specific JSON response I have to parse but I am finding no luck doing it.
I am using Volley for Parsing Request.
Here is my response:
{
"error": false,
"message": "Favourties fetched successfully",
"code": 200,
"data": [
{
"id": "5f1980f8c42e1f60854c57e4",
"type": 1,
"status": 1,
"favourite": {
"_id": "5f118057f44ebd1cead089db",
"firstName": "Bilal",
"lastName": "Khan",
"businessName": "Master Paint",
"image": "https://welist-assets.s3.us-west-2.amazonaws.com/profile_images/1592383845941-default_avatar.png"
},
"createdAt": "2020-07-23T12:22:16.731Z",
"updatedAt": "2020-07-23T12:22:16.731Z"
},
{
"id": "5f198084c42e1f60854c57e2",
"type": 3,
"status": 1,
"favourite": {
"images": [],
"_id": "5f12d5345478a53584eca98b",
"name": "Water Paint7"
},
"createdAt": "2020-07-23T12:20:20.680Z",
"updatedAt": "2020-07-23T12:20:20.680Z"
}
]
}
I am able to get the Array which contains 2 object, but I am unable to get the data inside the nested favorites.
try {
Log.d("Onresponse", response);
//converting the string to json array object
JSONObject obj = new JSONObject(response);
JSONArray array = obj.getJSONArray("data");
//traversing through all the object
for (int i = 0; i < array.length(); i++) {
//getting product object from json array
JSONObject favorites = array.getJSONObject(i);
Log.d("lenght", favorites.getString("status"));
//adding the product to product list
favoriteList.add(new FavoriteVendorsModel(
favorites.getString("firstName"),
favorites.getString("lastName"),
favorites.getString("businessName"),
favorites.getString("image")
));
}
Here is my method.
You have skipped one level of nesting. By calling array.getJSONObject(i) you get:
{
"id": "5f1980f8c42e1f60854c57e4",
"type": 1,
"status": 1,
"favourite": {
"_id": "5f118057f44ebd1cead089db",
"firstName": "Bilal",
"lastName": "Khan",
"businessName": "Master Paint",
"image": "https://welist-assets.s3.us-west-2.amazonaws.com/profile_images/1592383845941-default_avatar.png"
},
"createdAt": "2020-07-23T12:22:16.731Z",
"updatedAt": "2020-07-23T12:22:16.731Z"
}
And you are trying to call directly on that object next getString methods:
favorites.getString("firstName");
favorites.getString("lastName");
favorites.getString("businessName");
favorites.getString("image");
When actually you must first get JSONObject named favourite and then call these getString method on it:
JSONObject favorite = favorites.getJSONObject("favourite");
favorite.getString("firstName");
favorite.getString("lastName");
favorite.getString("businessName");
favorite.getString("image");
I'm new to android. I have a JSON file with multiple arrays and I'm able to fetch data from the first array and display it in listview (check the first for loop). But i tried to fetch the next array and i didn't get any results(blank screen). I need to display values from "open_days" array. Posted my JSON file and for loop portion.Please check and help me
MainActivity. java
try {
JSONObject jjsonObject =new JSONObject(result);

Your Logcat throws JSONException.
Don't
JSONArray array2=jjsonObject.getJSONArray("open_days");
Do
JSONArray array2=objects.getJSONArray("open_days");
You are using the wrong object to fetch open_days
Change
JSONArray array2 = jjsonObject.getJSONArray("open_days");
to
JSONArray array2 = objects.getJSONArray("open_days");
I have a nested JSON array which I want to decode. I have already found a way to decode a specified info in the object but it's not working so good.
This is the code I used to decode (name, cover and street) from the JSON object:
JSONArray jsonArray = response.getJSONArray("data");
for (int i=0; i < jsonArray.length();i++){
JSONObject events = jsonArray.getJSONObject(i);
String name = events.getString("name");
JSONObject cover = events.getJSONObject("cover");
String imgurl = cover.getString("source");
JSONObject place = events.getJSONObject("place");
JSONObject loc = place.getJSONObject("location");
String street = loc.getString("street");
ItemListView item = new ItemListView(name,street,imgurl);
listItems.add(item);
adapter = new ItemListAdapter(listItems, getActivity());
recyclerView.setAdapter(adapter);
}
I want to decode more info like description, end_time and start_time.
The JSON data structure looks like this:
{
"data": [
{
"description": "",
"end_time": "",
"name": "",
"place": {
"name": "",
"location": {
"city": "",
"country": "",
"latitude": 0000000,
"longitude": 000000,
"street": ""
},
"id": ""
},
"start_time": "",
"id": ""
},
{
"description": "",
"end_time": "",
"name": "",
"place": {
"name": "",
"location": {
"city": "",
"country": "",
"latitude": 0000000,
"longitude": 000000,
"street": ""
},
"id": ""
},
"start_time": "",
"id": ""
}
]
}
I put the decoded info in a ListView in my Android app and that is why I have an adapter and ListView in the code.
Any help is greatly appreciated :)
Thanks in advance.
This is simple you can get other string like this -:
JSONArray jsonArray = response.getJSONArray("data");
for (int i=0; i < jsonArray.length();i++){
JSONObject events = jsonArray.getJSONObject(i);
String description= events.getString("description");
String end_time= events.getString("end_time");
String start_time= events.getString("start_time");
}

How do I parse JSON in Android? [duplicate]

Closed 5 years ago.
I am developing a map application on Android which is about finding best roads.
The problem is not all roads name are on Google API so i have it on one JSon file.
Which is the best way to get coordinates from JSon file and show it to Android App
with lines from position A to B.

Try this
private List<LatLng> getLocationList(String JSON_String)
{
List<LatLng> locationList = new ArrayList<>();
try {
JSONObject object = new JSONObject(JSON_String);
JSONArray mArray = object.getJSONArray("features");
for(int i=0;i<mArray.length();i++){
JSONObject obj=mArray.getJSONObject(i);
JSONObject geometryObject=obj.getJSONObject("geometry");
JSONArray locationJSON_Array=geometryObject.getJSONArray("coordinates");
LatLng location=new LatLng(locationJSON_Array.getDouble(0),locationJSON_Array.getDouble(1));
locationList.add(location);
}
}catch (JSONException ex){
ex.printStackTrace();
//handle Exception
}
return locationList;
}
Use it like this
List<LatLng> LocationList =getLocationList(Your_JSON_String);//The String posted in question
LatLng firstLocation=locationList.get(0);
LatLng secondLocation=locationList.get(1);
Let me Know if anything goes wrong
Just try to parse like this:
JSONArray lat_long_jsonArray = jsonObject.getJSONArray("coordinates");
if (lat_long_jsonArray.length() != 0)
{
String Longitude(lat_long_jsonArray.get(0).toString());
String Latitude(lat_long_jsonArray.get(1).toString());
}
I need to get the images array data how to put into the adapter and not required adapter code? Only loop and how to add that's important for me
and then after second I can access option_value array.
First all images can be accessed then after a option_value array.

You should really look into How to parse JsonObject / JsonArray in android.
Please put your code of also what you have tried because people are here to help solve error/problem not to do coding.
Here is code from which you can Parse your json
JSONObject jsonObject = new JSONObject();
JSONObject dataObject = jsonObject.getJSONObject("data");
JSONArray imagesArray = dataObject.getJSONArray("images");
ArrayList<String> listOfImagesUrl = new ArrayList<>();
for(int i = 0; i < imagesArray.length(); i++)
{
listOfImagesUrl.add(imagesArray.getString(i)); // listOfImages
}
// code for option value
JSONArray optionsArray = dataObject.getJSONArray("options");
for(int i = 0; i < optionsArray.length(); i++)
{
JSONObject option = optionsArray.getJSONObject(i);
JSONArray optionsValueArray = option.getJSONArray("option_value");
for(int j = 0 ; j < optionsValueArray.length(); j++)
{
JSONObject optionValueObject = optionsValueArray.getJSONObject(j);
String image = optionValueObject.getString("image");
String price = optionValueObject.getString("price");
String price_prefix = optionValueObject.getString("price_prefix");
//same like this
}
}
