I am new to android, As I am trying to parse the Google's spreadsheet data and it is somewhat complex to me, I have to fetch $t of gsx$tag and $t of gsx$datetime,
This is the link from which we can get the JSON data
https://spreadsheets.google.com/feeds/list/1_AR0zX6Jv0NI_R1HBULbPEIUuJ2mqVbLoHVvLqOwu1I/1/public/values?alt=json
Data look like this
{
"version":"1.0",
"encoding":"UTF-8",
"feed":{
"xmlns":"http://www.w3.org/2005/Atom",
"xmlns$openSearch":"http://a9.com/-/spec/opensearchrss/1.0/",
"xmlns$gsx":"http://schemas.google.com/spreadsheets/2006/extended",
"id":{ },
"updated":{ },
"category":[ ],
"title":{ },
"link":[ ],
"author":[ ],
"openSearch$totalResults":{ },
"openSearch$startIndex":{ },
"entry":[
{
"id":{ },
"updated":{ },
"category":[ ],
"title":{ },
"content":{ },
"link":[ ],
"gsx$id":{
"$t":"1"
},
"gsx$datetime":{
"$t":"3/28/2017"
},
"gsx$tag":{
"$t":"21"
}
},
{ Data here },
{ Data here }
]
}
}
and below is the code I am trying
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(url);
Log.e(TAG, "Response from url: " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONObject mainObj = new JSONObject(jsonStr);
Log.e(TAG,"JSon Data"+mainObj);
if (mainObj != null) {
Log.e(TAG,"JSon before feed"+mainObj.toString());
JSONArray a = mainObj.getJSONArray("feed");
Log.e(TAG,"JSon after feed"+a.toString());
JSONObject entru= new JSONObject((Map) a);
JSONArray list = entru.getJSONArray("entry");
// JSONArray entryarray = list.getJSONArray("entry");
if (list != null) {
for (int i = 0; i < list.length(); i++) {
JSONObject elem = list.getJSONObject(i);
if (elem != null) {
JSONArray prods = elem.getJSONArray("gsx$tag");
if (prods != null) {
for (int j = 0; j < prods.length(); j++) {
JSONObject innerElem = prods.getJSONObject(j);
if (innerElem != null) {
String sku = innerElem.getString("$t");
Log.e(TAG, "$t" + sku);
HashMap<String, String> contact = new HashMap<>();
contact.put("$t Datetime", sku);
// adding contact to contact list
contactList.add(contact);
}
}
}
}
}
}
}
Help Me in this regards, Thank you in advance
JSONArray a = mainObj.getJSONArray("feed");
Log.e(TAG,"JSon after feed"+a.toString());
JSONObject entru= new JSONObject((Map) a);
replace this 3 lines with the below one
JSONObject entru= mainObj.getJSONObject("feed");
also replace this line
JSONArray prods = elem.getJSONArray("gsx$tag");
with this one
JSONObject prods = elem.getJSONObject("gsx$tag");
I think this is the correct code.
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(url);
Log.e(TAG, "Response from url: " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONObject mainObj = new JSONObject(jsonStr);
Log.e(TAG,"JSon Data"+mainObj);
if (mainObj != null) {
Log.e(TAG,"JSon before feed"+mainObj.toString());
JSONObject entru= mainObj.getJSONObject("feed");
JSONArray list = entru.getJSONArray("entry");
//JSONArray entryarray = list.getJSONArray("entry");
if (list != null) {
for (int i = 0; i < list.length(); i++) {
JSONObject elem = list.getJSONObject(i);
if (elem != null) {
JSONObject prods = elem.getJSONObject("gsx$tag");
if (prods != null) {
for (int j = 0; j < prods.length(); j++) {
String sku = prods.getString("$t");
Log.e(TAG, "$t" + sku);
HashMap<String, String> contact = new HashMap<>();
contact.put("$t Datetime", sku);
// adding contact to contact list
contactList.add(contact);
}
}
}
}
}
}
Please try this. If this doesn't work please feel free to ask. will help you
You can try using Gson or Jackson

and my Code to parse the above data is
public class CurriculaParser {
public ArrayList<CurriculaData> getData(String response)
{
ArrayList<CurriculaData> dataList = new ArrayList<>();
try {
JSONObject mainObj = new JSONObject(response);
JSONArray array = mainObj.getJSONArray("results");
CurriculaData data;
for(int i = 0;i<array.length();i++)
{
data = new CurriculaData();
JSONObject resObj = array.getJSONObject(i);
JSONArray reqArray = resObj.getJSONArray("requires");
for( int j =0;j<reqArray.length();j++) {
JSONObject reqObj = reqArray.getJSONObject(j);
JSONObject innerObj = reqObj.getJSONObject("learningEvent");
data.setTitle(innerObj.getString("displayName"));
data.setAssignedOn(reqObj.getString("assignedOn"));
}
JSONArray basicDetailArray = resObj.getJSONArray("basicdetail");
for(int k=0;k<basicDetailArray.length();k++) {
JSONObject basicDetailObj = basicDetailArray.getJSONObject(k);
JSONObject statusObj = basicDetailObj.getJSONObject("status");
data.setStatus(statusObj.getString("displayName"));
data.setAcquiredOn(basicDetailObj.getString("acquiredOn"));

data.setAssignedBy(assignObj.getString("displayName"));
}
dataList.add(data);
}
} catch (Exception e) {
e.printStackTrace();
}
return dataList;
}
and finally i got error like
org.json.JSONException: No value for requires
let me know the error what i made and iam a beginner in dealing with jsonarray inside another jsonarray
org.json.JSONException: No value for requires
JSONException
KEY mismatches on lookups
You should pass requirers instead of requires.
JSONArray reqArray = resObj.getJSONArray("requirers");
fixed the requires TYPO error
public class CurriculaParser {
public ArrayList<CurriculaData> getData(String response)
{
ArrayList<CurriculaData> dataList = new ArrayList<>();
try {
JSONObject mainObj = new JSONObject(response);
JSONArray array = mainObj.getJSONArray("results");
CurriculaData data;
for(int i = 0;i<array.length();i++)
{
data = new CurriculaData();
JSONObject resObj = array.getJSONObject(i);
JSONArray reqArray = resObj.getJSONArray("requirers");
for( int j =0;j<reqArray.length();j++) {
JSONObject reqObj = reqArray.getJSONObject(j);
JSONObject innerObj = reqObj.getJSONObject("learningEvent");
data.setTitle(innerObj.getString("displayName"));
data.setAssignedOn(reqObj.getString("assignedOn"));
}
JSONArray basicDetailArray = resObj.getJSONArray("basicdetail");
for(int k=0;k<basicDetailArray.length();k++) {
JSONObject basicDetailObj = basicDetailArray.getJSONObject(k);
JSONObject statusObj = basicDetailObj.getJSONObject("status");
data.setStatus(statusObj.getString("displayName"));
data.setAcquiredOn(basicDetailObj.getString("acquiredOn"));
JSONObject assignObj = basicDetailObj.getJSONObject("assignee");
data.setAssignedBy(assignObj.getString("displayName"));
}
dataList.add(data);
}
} catch (Exception e) {
e.printStackTrace();
}
When I'm JSONObject jsonObj = new JSONObject(jsonStr);
I enter in catch because my json is not a array.
How can I get this format ?
protected Void doInBackground(Void... arg0) {
HttpHandler sh = new HttpHandler();

String url = "http://10.0.2.2:8080/PFA/crimes";

// Getting JSON Array node
JSONArray data = jsonObj.getJSONArray("crime");
// looping through All Contacts
for (int i = 0; i < data.length(); i++) {
JSONObject c = data.getJSONObject(i);
String day_week = c.getString("day_week");
String naturecode = c.getString("naturecode");
// tmp hash map for single contact
HashMap<String, String> contact = new HashMap<>();
// adding each child node to HashMap key => value
contact.put("day_week", day_week);
contact.put("naturecode", naturecode);
// adding contact to contact list
List.add(contact);
}
} catch (final JSONException e) {

There is no jsonArray in your json value. Give up to get jsonArray.
Try this:
JSONObject jsonObj = new JSONObject(jsonStr);
JSONObject jsonMetaObject = jsonMasterObject.getJSONObject("crime");
instead of
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
JSONArray data = jsonObj.getJSONArray("crime");
Because you get jsonObject in key of crime not JsonArray.
I have an array jArray in the format :
{"users":[
{
"user_id":6,
"user_name":"Ted Vanderploeg",
"email":"test5#test.com",
"additional_info":[["HP","Chief Sales Officer","","",1]]
},
{
"user_id":59,
"user_name":"Lindsay White",
"email":"test12260#test.com",
"additional_info":[["Microsoft","Global Head","","",1]]
}
]
}
Now I need to get the value "Microsoft" from additional_info array. This is what I'm trying :
for(int i=0;i<jArray.length();i++) {
JSONObject jsonObject = new JSONObject(jArray.getString(i));
String workInfo = jsonObject.getString("additional_info");
Log.i("MyActivity", "got work obj as " + workInfo.toString());
}
Now I get workInfo as [["Microsoft","Global Head","","",1]]. Stuck on how to proceed next, to get the value Microsoft.
it looks like a JSONArray inside a JSONArray
for(int i=0;i<jArray.length();i++) {
JSONObject jsonObject = new JSONObject(jArray.getString(i));
JSONArray workinfo = jsonObject.optJSONArray("additional_info");
if (workinfo != null) {
for(int j=0;j<workinfo.length();j++) {
JSONArray values = workinfo.optJSONArray(j);
for(int z=0;z<values.length();z++) {
Log.i("MyActivity", "got work obj as " + values.optString(z));
}
}
}
}
I need to get Particular Object values ( A, B, C, D) and related key values (#"name" ). After getting (A, B, C, D ) object values I need to list out into list view Android. Here below I have posted my sample code and response. Please help me.
#Override
protected Void doInBackground(Void... arg0) {
// Creating service handler class instance
ServiceHandler sh = new ServiceHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(url, ServiceHandler.GET);
Log.d("Response: ", "> " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
contacts = jsonObj.getJSONArray("response");
Log.d("Response: ", "> " + contacts);
// looping through All Contacts
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return null;
}
My JSON Response :
{"response" : [ {
"A" : [ {
"name" : "tango"
},
{
"name" : "ping"
}
],
"B" : [ {
"name" : "tango"
},
{
"name" : "ping"
}
]
} ]}
Use JSONObject keys() to get the key and then iterate each key to get to the dynamic value.
You can get dynamic keys like this
JSONObject responseDataObj = new JSONObject(responseData);
JSONArray responseArray = responseDataObj.getJSONArray("response");
for (int i = 0; i < responseArray.length(); i++) {
nodes = new ArrayList<ArrayList<String>>();//nodes ArrayList<ArrayList<String>> declared globally
nodeSize = new ArrayList<Integer>();//nodeSize ArrayList<Integer> declared globally
JSONObject obj = responseArray.getJSONObject(i);
Iterator keys = obj.keys();
while(keys.hasNext()) {
// loop to get the dynamic key
String currentDynamicKey = (String)keys.next();
//store key in an arraylist which is A,B,...
// get the value of the dynamic key
JSONArray currentDynamicValue = obj.getJSONArray(currentDynamicKey);
int jsonrraySize = currentDynamicValue.length();
int sizeInArrayList = jsonrraySize + 1;
nodeSize.add(sizeInArrayList);
if(jsonrraySize > 0) {
for (int ii = 0; ii < jsonrraySize; ii++) {
nameList = new ArrayList<String>();//nameList ArrayList<String> declared globally
if(ii == 0) {
JSONObject nameObj = currentDynamicValue.getJSONObject(ii);
String name = nameObj.getString("name");
System.out.print("Name = " + name);
//store name in an arraylist
nameList.add(name);
}
}
}
nodes.add(nameList);
}
}
You can use following method to parse your response and handle output as per requirement.
private void parseJson(String res) {
try {
JSONObject mainObject = new JSONObject(res);
JSONArray response = mainObject.getJSONArray("response");
for (int i = 0; i < response.length(); i++) {
JSONObject obj = response.getJSONObject(i);
JSONArray A = obj.getJSONArray("A");
for (int j = 0; j < A.length(); j++) {
JSONObject objA = A.getJSONObject(j);
String name = objA.getString("name");
// use or store name here
}
JSONArray B = obj.getJSONArray("B");
for (int k = 0; k < B.length(); k++) {
JSONObject objB = B.getJSONObject(k);
String name = objB.getString("name");
// use or store name here
}
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
This may work for you :
String jsonStr = sh.makeServiceCall(url, ServiceHandler.GET);
Log.d("Response: ", "> " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONArray contacts;
contacts = jsonObj.getJSONArray("response");
Log.d("Response: ", "> " + contacts);
// looping through All Contacts
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
JSONArray jsonArrayA=new JSONArray();
jsonArrayA=c.getJSONArray("A");
for(int j=0;j<jsonArrayA.length();j++){
String name=jsonArrayA.getJSONObject(j).getString("name");
Log.e("Name","name of jsonarray A "+i+" "+name);
}
JSONArray jsonArrayB=c.getJSONArray("B");
for(int k=0;k<jsonArrayB.length();k++){
String name=jsonArrayB.getJSONObject(k).getString("name");
Log.e("Name","name of jsonarray B "+i+" "+name);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
I have a json response below.
