Read the JSON response in Android - android

I am getting below JSON response and I have to store both the data in spinner but when I select Alabama the "AL" in toast message should be used. How can I do this?
{
"status" : "success",
"data" : {
"AL" : "Alabama",
"AK" : "Alaska"
}
}

Try
JSONObject jsonObject = new JSONObject(jsonString);
String status = jsonObject.getString("status");
List<String> data = new ArrayList<String>();
JSONArray array = jsonObject.getJSONArray("data");
Iterator<String> keys = jsonObject.keys();
while (keys.hasNext()) {
String key = keys.next();
String value = jsonObject.getString(key);
}

Try this my friend
JSONObject jsonObject = new JSONObject(response);
Iterator<String> keys = jsonObject.keys();
while (keys.hasNext()) {
String key = keys.next();
String value = jsonObject.getString(key);
Log.v("**********", "**********");
Log.v("category key", key);
Log.v("category value", value);
String firstChar = String.valueOf(value.charAt(0));
if (firstChar.equalsIgnoreCase("{")) {
JSONObject innerJObject = jsonObject.getJSONObject(key);
Iterator<String> innerkeys = innerJObject.keys();
String innerkey = innerkeys.next();
String innervalue = innerJObject.getString(innerkey);
Log.v("**********", "**********");
Log.v("inner key", innerkey);
Log.v("inner value", innervalue);
}
}

Hello Try this if it helps
public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
List<City>cityList= new ArrayList<>();
List<String> cityListName= new ArrayList<>();
Spinner spnCity;
#Override
protected void onCreate(Bundle savedInstanceState) {

String response="{\"status\":\"success\",\"data\":{\"AL\":\"Alabama\",\"AK\":\"Alaska\"}}";
try {
JSONObject iObject=new JSONObject(response);
JSONObject data=iObject.getJSONObject("data");
Iterator<String> iter = data.keys();
while (iter.hasNext()) {
String key = iter.next();
try {
Object value = data.get(key);
cityListName.add(value.toString());
cityList.add(new City(key,value.toString()));
} catch (JSONException e) {
}
}

// Drop down layout style - list view with radio button
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
spnCity.setAdapter(dataAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String item = adapterView.getItemAtPosition(i).toString();
for (int j = 0; j < cityList.size(); j++) {
if(cityList.get(j).getCityName().equals(item)){
Toast.makeText(adapterView.getContext(), "Selected: " + item +" "+cityList.get(j).getCityName(), Toast.LENGTH_LONG).show();
}
}
// Showing selected spinner item
}
#Override

Retrieving all values of json object into array list

I have a json object as below
{
"Book1":{"Title1":"Cost1","Title2":"Cost2"},
"Book2":{"Title3 ":"Cost3"},
"Book3":{"Title4 ":"Cost4","Title5 ":"Cost5"},
"Book4":{"Title6":"Cost6","Title7”:”Cost7","Title8”:”Cost8"}
}
I want to retrieve all the values of "Titles" without any keywords i.e I would like to have {Title1,Title2,Title3,Title4,...} in an array.
Below is my code to retrieve based on Book name but now I need to retrieve all the values
List<String> books=new ArrayList<String >();
try {
JSONObject obj = new JSONObject(loadJSONFromAssetArea());
JSONObject bookJson = obj.getJSONObject("Book1");
Iterator<String> keys= bookJson.keys();
do
{
String keyValue = (String)keys.next();
JSONArray specTitle = obj.getJSONArray(keyValue);
for (int i = 0; i < specTitle.length(); i++) {
books.add(specTitle.get(i).toString());
}
}while(keys.hasNext());
} catch (JSONException e) {
e.printStackTrace();
}
I am not getting how to get with out passing key values to json object .
Kindly help.
Thanks in advance
Try This is Working
JSONObject jsonObject = new JSONObject(loadJSONFromAssetArea());
List<String> books=new ArrayList<String >();
try {
Iterator iteratorObj = jsonObject.keys();
while (iteratorObj.hasNext())
{
String getJsonObj = (String)iteratorObj.next();
System.out.println("Book No.: " + "------>" + getJsonObj);
JSONObject jo_inside = jsonObject.getJSONObject(getJsonObj);
//JSONObject jo_inside = new JSONObject((String) iteratorObj.next());
Iterator<String> keys = jo_inside.keys();
while (keys.hasNext())
{
String key = keys.next();
String value = jo_inside.getString(key);
Log.v("Book Title key", key);
Log.v("Book Name value", value);
books.add(jo_inside.getString(key));
}
}
} catch (JSONException e) {
e.printStackTrace();
}
NOTE
Your GIVEN Json is not Valid.
Book1,Book2.. are DYNAMIC/UNKNOWN.
Use Iterator in this way.
Try this way,
JSONObject jOBJ= new JSONObject(loadJSONFromAssetArea());
Iterator iteratorObj = jOBJ.keys();
while (iteratorObj.hasNext())
{
String getJsonObj = (String)iteratorObj.next();
System.out.println("Key: " + Key + "------>" + getJsonObj); // print Book1,Book2..
// Now your work
}
If you want to parse this
{
"Book1":{"Title1":"Cost1","Title2":"Cost2"},
"Book2":{"Title3 ":"Cost3"},
"Book3":{"Title4 ":"Cost4","Title5 ":"Cost5"},
"Book4":{"Title6":"Cost6","Title7”:”Cost7","Title8”:”Cost8"}
}
you can use this code to parse the json object,
List<String> books = new ArrayList<String>();
try {
JSONObject obj = new JSONObject(loadJSONFromAssetArea());
JSONObject bookJson, innerObject;
Iterator<String> keys = obj.keys();
do {
String keyValue = (String) keys.next();
if (obj.get(keyValue) instanceof JSONObject) {
bookJson = obj.getJSONObject(keyValue);
Iterator<?> innerKeys = bookJson.keys();
while (innerKeys.hasNext()) {
String innerKey = (String) innerKeys.next();
innerObject = bookJson.getJSONObject(innerKey);
books.add(innerObject.getString(innerKey));
}
}
} while (keys.hasNext());
} catch (JSONException e) {
e.printStackTrace();
}

You had done everything correct uptil now. Just make my suggestion and you are good to go with long list of JSON data.
First make the JSON Response of file accessible to whole activity/fragment by declaring at top.
Added following function to retrieve cityList of particular country:
private ArrayList<String> getCityList(String countryName){
ArrayList<String> cityList = new ArrayList<>();
//Here jsonObj is the your JSON response from the file.
try {
JSONArray jArray =jsonObj.getJSONArray(countryName);
for(int i=0;i<jArray.length();i++){
cityList.add(jArray.getString(i));
}
} catch (JSONException e) {
e.printStackTrace();
}
return cityList;
}
Then add on spinnerItemSelected call the below function:
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String selected = ((SpinnerModel) parent.getSelectedItem()).getCountryName();
//For sake of your answer I had used String Array and ArrayAdapter. You can modify as you want.
ArrayAdapter<String> cityAdapter = new ArrayAdapter<String>(YourActivity.this, R.layout.single_textview,getCityList(selected));
spinnerCity.setAdapter(cityAdapter);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Json array parsing always has null result in Android

How I can parse this json array?
{"1":
{"0":"3","id_disc":"3","1":"Дослідження і проектування компютерних систем","name":"Дослідження і проектування компютерних систем","2":"ДПКМС ","s_name":"ДПКМС "}
,"2":
{"0":"5","id_disc":"5","1":"Цивільний захист і охорона праці в галузі","name":"Цивільний захист і охорона праці в галузі","2":"ЦЗ і ОП","s_name":"ЦЗ і ОП"}
,"3":
{"0":"1","id_disc":"1","1":"Дослідження і проектування інтелектуальних систем (Лекція)","name":"Дослідження і проектування інтелектуальних систем (Лекція)","2":"ДіПІС","s_name":"ДіПІС"}
}
I was trying this method, but I always have null result.
String[] sA = new String[100];
try {
JSONArray cast = getDisc(paraaams).getJSONArray(" ");
for (int i=0; i<cast.length(); i++) {
JSONObject disc = cast.getJSONObject(i);
sA[i-1] = disc.getString("name");
}
}catch (JSONException e){}
// sA[0]=getDisc(paraaams).toString();
ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(),
android.R.layout.simple_list_item_1, sA);
listView.setAdapter(adapter);
public JSONArray getDisc(Object params[]){
HTTPWorker httpWorker=new HTTPWorker();
JSONArray mjson =new JSONArray();
String s = httpWorker.doInBackground(params);
try {
mjson = new JSONArray(s);
Log.e("JSONinClass ",mjson.toString());
}catch (JSONException e){}
return mjson;
I think i try to parse it like json object, but i don't know how correct work with json arrays.
Thanks for help:)

I cut it a bit, removed it is not important for the question :)
Try this for your Response to Parse
May Help you
try{
JSONObject jsonObject = new JSONObject(response);
List<String> keyList = getAllKeys(jsonObject);
for(String key : keyList){
JSONObject innerObject = jsonObject.getJSONObject(key);
List<String> innerKeyList = getAllKeys(innerObject);
for(String innerKey: innerKeyList){
System.out.println(innerObject.getString(innerKey));
}
}
}catch(Exception e){
e.printStackTrace();
}
This method will return keys
private List<String> getAllKeys(JSONObject jsonObject) throws JSONException{
List<String> keys = new ArrayList<String>();
Iterator<?> iterator = jsonObject.keys();
while( iterator.hasNext() ) {
String key = (String)iterator.next();
keys.add(key);
}
return keys;
}
try this:
please check below changes replace array to arraylist
public class MyFilesActivity extends android.app.Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_myfiles, null);
ListView listView = (ListView) rootView.findViewById(R.id.listView);
ArrayList<String> sA = new ArrayList<>();
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(getDisc(paraaams).toString());
} catch (JSONException e) {
e.printStackTrace();
}
Iterator<String> iterator = jsonObject.keys();
while (iterator.hasNext()) {
String key = iterator.next();
try {
if (jsonObject.has(key)) {
JSONObject value = jsonObject.getJSONObject(key);
// value is another JSONObject where you can get the "name" from
String name = value.getString("name");
sA.add(name);
Log.e("value= ", name);
}
} catch (JSONException e) {
// Something went wrong!
e.printStackTrace();
}
}
// sA[0]=getDisc(paraaams).toString();
ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(),
android.R.layout.simple_list_item_1, sA);
listView.setAdapter(adapter);
return rootView;
}
Here is a tested code to parse json.
try {
JSONObject json = new JSONObject(json);
int jsonLength = json.length();
for(int i=1; i<=jsonLength; i++){
JSONObject jObject = json.getJSONObject(""+i);
String data = jObject.getString("0");
}
} catch (JSONException e) {
e.printStackTrace();
}
It is just a plain JSONObject not an JSONArray, so you have to cast it to a JSONObject first
JSONObject json = new JSONObject(jsonString);
To loop through it
for (Iterator<String> iter = json.keys(); iter.hasNext();) {
String key = iter.next();
JSONObject value = (JSONObject) json.getJSONObject(key);
String name = value.getString("name");
}

how to access an element of an JSON array

Given below is my JSON and I want to access "trips" JSON array and want to place it in an array list so that I can use it in a spinner. How can I access trips JSON array directly and use as a ArrayList for spinner?
My JSON:
{
"trips": [
77
],
"status": {
"message": "Successfully fetched the Open trips ",
"code": 200
}
}
My Activity class:
public class MainActivity extends AppCompatActivity implements Spinner.OnItemSelectedListener {
private Spinner spinner;
private ArrayList<String> trips;
private JSONArray result;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
trips= new ArrayList<String>();
this.spinner = (Spinner) findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(this);
loadtrip();
}
public void loadtrip() {
HashMap<String,String> params=new HashMap<String,String>();
{
params.put("systemId", "12");
params.put("customerId", "3513");
params.put("userId", "124");
params.put("tripType", "Open");
}
JsonObjectRequest stringRequest = new JsonObjectRequest(Request.Method.POST,config.DATA_URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
public void onResponse(JSONObject response) {
try {
result = response.getJSONArray(config.JSON_ARRAY);
} catch (JSONException e) {
e.printStackTrace();
}
spinner.setAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item,trips));
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) ;
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String item = parent.getItemAtPosition(position).toString();
Toast.makeText(parent.getContext(), "Selected: " + item, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
}
You can get value from json array directly from its index.
JSONArray array = yourJsonObject.getJSONArray("trips");
for (int i=0; i<array.length(); i++) {
int value = array.getInt(i);
}
JSONArray array = yourJsonObject.getJSONArray("trips");
for (int i=0; i<array.length(); i++)
{
int value = array.getInt(i);
}
JSONObject objStates = yourJsonObject.getJSONObject(“status”);
String msg= objStates.getString(“message”)
Int code= objStates.getInt(“code”)
Try something like
try {
result = response.getJSONArray("trips");
for(int i = 0; i < result.length(); i++){
trips.add(String.valueOf(result.getInt(i)));
}
} catch (JSONException e) {
e.printStackTrace();
}
Declare int value; and parse JSON:
new Response.Listener<JSONObject>() {
public void onResponse(JSONObject response) {
try {
result = response.getJSONArray("trips");
for (int i=0; i<result.length(); i++) {
value = result.getInt(i);
trips.add(String.valueOf(value));
}
} catch (JSONException e) {
e.printStackTrace();
}
spinner.setAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item,trips));
As you are using config.JSON_ARRAY key to parse in your code, what is the value for config.JSON_ARRAY. If config.JSON_ARRAY="trips" then fine and replace static "trips" key with yours config.JSON_ARRAY else follow mine static key to parse.
Just update your code with this one: In this I parsed the trips JSON array and added all the items to the trips ArrayList.
public class MainActivity extends AppCompatActivity implements Spinner.OnItemSelectedListener {
private Spinner spinner;
private ArrayList<String> trips;
private JSONArray result;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
trips= new ArrayList<String>();
this.spinner = (Spinner) findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(this);
loadtrip();
}
public void loadtrip() {
trips = new ArrayList<>();
HashMap<String,String> params=new HashMap<String,String>();
{
params.put("systemId", "12");
params.put("customerId", "3513");
params.put("userId", "124");
params.put("tripType", "Open");
}
JsonObjectRequest stringRequest = new JsonObjectRequest(Request.Method.POST,config.DATA_URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
public void onResponse(JSONObject response) {
try {
result = response.optJSONArray("trips");
for(int i = 0; i < result.length(); i++){
trips.add(String.valueOf(result.getInt(i)));
}
} catch (JSONException e) {
e.printStackTrace();
}
spinner.setAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item,trips));
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) ;
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String item = parent.getItemAtPosition(position).toString();
Toast.makeText(parent.getContext(), "Selected: " + item, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
}
Try this it works for me.
JSONObject object = jObj.getJSONObject(result);
Iterator<?> iterator = object.keys();
while (iterator.hasNext()) {
String key = (String) iterator.next();
ArrayList<JSONObject> value = new ArrayList<>();
JSONArray jsonArray = object.getJSONArray(key);
for (int i = 0; i < jsonArray.length(); i++) {
value.add(jsonArray.getJSONObject(i));
}
System.out.println("key : " + key + " " + "value : " + value);
hm.put(key, value);
}

How to sort a jsonarray data by Date & Time and put in list view adapter

here my jsonArray data like:
[{"LeadId":4,
"CoreLeadId":0,
"CompanyId":7,
"AccountNo":"5675",
"ScheduleOn":"2015-05-11T00:00:00"},
{"LeadId":7,
"CoreLeadId":2,
"CompanyId":8,
"AccountNo":"sample string 4",
"ScheduleOn":"2015-12-01T15:04:23.217"}]
i want to sort by dateandtime(ScheduleOn) and put into listview. below i side i send snnipt of my code where i set adapter. can we sort into listItemService. Please help me.
JSONArray jsonArray = dpsFunctionFlow.getAllServiceDetail("1");
listItemService = new Gson().fromJson(jsonArray.toString(),
new TypeToken<List<AppointmentInfoDto>>() {
}.getType());
mAdapter = new AdapterAppointment(getActivity(), listItemService);
listView.setAdapter(mAdapter);
You should be able to use Collections.sort(...) passing in a Comparator that will compare 2 AppointmentInfoDto objects.
Collections.sort(listItemService, new Comparator<AppointmentInfoDto>() {
#Override public int compare(AppointmentInfoDto l, AppointmentInfoDto r) {
// Compare l.ScheduleOn and r.ScheduleOn
}
}
/// Sort JSON By any Key for date
public static JSONArray sortJsonArray(JSONArray array,final String key, final boolean isCase) {
List<JSONObject> jsonsList = new ArrayList<JSONObject>();
try {
for (int i = 0; i < array.length(); i++) {
jsonsList.add(array.getJSONObject(i));
}
Collections.sort(jsonsList, new Comparator<JSONObject>() {
#Override
public int compare(JSONObject v_1, JSONObject v_2) {
String CompareString1 = "", CompareString2 = "";
try {
CompareString1 = v_1.getString(key); //Key must be present in JSON
CompareString2 = v_2.getString(key); //Key must be present in JSON
} catch (JSONException ex) {
// Json Excpetion handling
}
return CompareString1.compareTo(CompareString2);
}
});
} catch (JSONException ex) {
// Json Excpetion handling
}
return new JSONArray(jsonsList);
}
// _Sort JSON for any String Key value.........
public static JSONArray sortJsonArray(JSONArray array,final String key, final boolean isCase) {
List<JSONObject> jsonsList = new ArrayList<JSONObject>();
try {
for (int i = 0; i < array.length(); i++) {
jsonsList.add(array.getJSONObject(i));
}
Collections.sort(jsonsList, new Comparator<JSONObject>() {
#Override
public int compare(JSONObject v_1, JSONObject v_2) {
String CompareString1 = "", CompareString2 = "";
try {
CompareString1 = v_1.getString(key); //Key must be present in JSON
CompareString2 = v_2.getString(key); //Key must be present in JSON
} catch (JSONException ex) {
// Json Excpetion handling
}
return isCase ? CompareString1.compareTo(CompareString2) : CompareString1.compareToIgnoreCase(CompareString2);
}
});
} catch (JSONException ex) {
// Json Excpetion handling
}
return new JSONArray(jsonsList);
}
