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);
String getObject = jjsonObject.getString("message");
String getObject1 = jjsonObject.getString("status");
JSONArray getArray = jjsonObject.getJSONArray("favorite_facility_list");
Log.e("message",getObject);
Log.e("status",getObject1);
Log.e("favorite_facility_list",getArray.toString());
for(int i = 0; i < getArray.length(); i++)
{
JSONObject objects = getArray.getJSONObject(i);
String promotion_id = objects.getString("facility_id");
String promotion_image_name = objects.getString("facility_course_name");
String promotion_image_url = objects.getString("icon_image_name");
JSONArray array2=jjsonObject.getJSONArray("open_days");
for(int j=0;j<array2.length();j++)
{
JSONObject obj2=array2.getJSONObject(j);
String openid = obj2.getString("open_days_id");
String openname = obj2.getString("open_days_name");
//
promotionlists promotionlists = new promotionlists();
promotionlists.setFacility_id(promotion_id);
promotionlists.setFacility_course_name(promotion_image_name);
promotionlists.setIcon_image_name(promotion_image_url);
promotionlists.setOpen_days_id(openid);
promotionlists.setOpen_days_name(openname);
promotionArray.add(promotionlists);
adapter= new CustomAdapter(promotionArray,getApplicationContext());
lv.setAdapter(adapter);

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");

This is my array
and
this is how I am calling from API.
This is my Java code. I used for loop inside for loop.
if (response.body().getDescriptionResponseData().getSuccess().equals("200")) {
attributeData = response.body().getDescriptionResponseData().getP_data().getAttributeData();
attribute_array_size = attributeData.size();
if (attributeData.size() == 0){
p_attribute.setVisibility(View.GONE);
} else {
p_attribute.setVisibility(View.VISIBLE);
// Loading attribute options
for (int j=0;j<attributeData.size();j++){
attributeOptions = response.body().getDescriptionResponseData().getP_data().getAttributeData().get(j).getAttributeOptionsData();
//String option = attributeOptions.get(j).getOption_name();
// Log.e("options",option);
dateList.clear();
dateList.add("Select");
for (int k=0;k<attributeOptions.size();k++){
String attribute_id = attributeOptions.get(k).getAttribute_id();
String option_name = attributeOptions.get(k).getOption_name();
String option_price = attributeOptions.get(k).getOption_price();
dateList.add(option_name);
//Log.e("option_id",attribute_id);
//Log.e("option_name",option_name);
// Log.e("option_price",option_price);
}
ArrayAdapter dateArrayAdapter = new ArrayAdapter(getContext(),R.layout.date_dialog, R.id.textDate, dateList);
holder.attribute_option_spinner.setAdapter(dateArrayAdapter);
}
}
}
From the question you asked I assume that your spinner shows last values. There are two problems with your code.
1- dateList.clear(); and dateList.add("Select"); should be outside for loop
2- Set spinner adapter outside for loop after all values are assigned to arrayList
Below you can check how it will go
if (response.body().getDescriptionResponseData().getSuccess().equals("200")) {
attributeData = response.body().getDescriptionResponseData().getP_data().getAttributeData();
attribute_array_size = attributeData.size();
if (attributeData.size() == 0){
p_attribute.setVisibility(View.GONE);
} else {
p_attribute.setVisibility(View.VISIBLE);
// Loading attribute options
dateList.clear();
dateList.add("Select");
for (int j=0;j<attributeData.size();j++){
attributeOptions = response.body().getDescriptionResponseData().getP_data().getAttributeData().get(j).getAttributeOptionsData();
//String option = attributeOptions.get(j).getOption_name();
// Log.e("options",option);
for (int k=0;k<attributeOptions.size();k++){
String attribute_id = attributeOptions.get(k).getAttribute_id();
String option_name = attributeOptions.get(k).getOption_name();
String option_price = attributeOptions.get(k).getOption_price();
dateList.add(option_name);
//Log.e("option_id",attribute_id);
//Log.e("option_name",option_name);
// Log.e("option_price",option_price);
}
}
if (dateList.size() > 0) {
ArrayAdapter dateArrayAdapter = new ArrayAdapter(getContext(), R.layout.date_dialog, R.id.textDate, dateList);
holder.attribute_option_spinner.setAdapter(dateArrayAdapter);
}
}
}
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.

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 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
}
}

I want to put the BattingDetail JSON array in Innings json array in JSON Structure.am not able solve this issue.can any one know help me to solve this issue.
Take your main json data into JSONObject.
JSONObject jsobj=new JSONObject(data);
JSONArray jsarBatting=new JSONArray(battingdetail);
JSONArray jsAr=jsobj.getJSONArray("innings");
JSONObject jsobj= jsAr.getJSONObject(0);
jsobj.put("BattingDetail",jsarBatting);

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");
