Retrieve data to ListView from API in android

I need to retrieve data to listview from this link http://www.autotrack.rs/android_juzna_backa/get_voznja.php?. I need to send key, with value-POST method, to get something like this: http://www.autotrack.rs/android_juzna_backa/get_voznja.php?voznja_id=42. My code is bellow: Thanks.

Your api response is JSONObject.
{"data":{"id":"42","vozilo_id":"777777003561","vozac_id":"2","pocetna_kilometraza":"50000","pocetno_vreme":"2020-12-25 07:15:00","projekat":null,"razlog":"Sastanak","zavrsna_kilometraza":"50150","zavrsno_vreme":"2020-12-25 10:45:00","moto_sati":"3","insert_time":"2021-01-08 10:47:33.683885","id_projekat_jb":"330"}}
So you should use JSONObject instead JSONArray
try {
JSONObject object = new JSONObject(rezultat);
JSONObject jsonObject = object.getJSONObject("data");
String id = jsonObject.getString("id");
String vozilo_id = jsonObject.getString("vozilo_id");
String vozac_id = jsonObject.getString("vozac_id");
String pocetna_kilometraza = jsonObject.getString("pocetna_kilometraza");
String pocetno_vreme = jsonObject.getString("pocetno_vreme");
String razlog = jsonObject.getString("razlog");
String zavrsna_kilometraza = jsonObject.getString("zavrsna_kilometraza");
String zavrsno_vreme = jsonObject.getString("zavrsno_vreme");
String moto_sati = jsonObject.getString("moto_sati");
String id_projekat_jb = jsonObject.getString("id_projekat_jb");
ItemModel model = new ItemModel();
model.setVoznja_id(id);
model.setVoziloId(vozilo_id);
model.setVozac_id(vozac_id);
model.setPocetnaKilometraza(pocetna_kilometraza);
model.setPocetnoVreme(pocetno_vreme);
model.setRazlog(razlog);
model.setZavrsnaKilometraza(zavrsna_kilometraza);
model.setZavrsnoVreme(zavrsno_vreme);
model.setMotoSati(moto_sati);
model.setProjekatId(id_projekat_jb);
arrayList.add(model);
} catch (JSONException e) {

How to print the json to listview included two data?

I want to display two data on listview through the json input. All the code are alter from internet which I got error. I have not clear logic to understand the meaning of the code. Please give me advice and alter my code.
private void displayArrayList(String jsonStr){
String[] from = {"eventName", "date"};
int[] to = {R.id.eventName, R.id.date};
SimpleAdapter simpleAdapter = new SimpleAdapter (
getActivity(),convertToＷordArrayList(jsonStr), R.layout.listview_layout,from,to);
simpleAdapter.notifyDataSetChanged();
listView.setAdapter(simpleAdapter);
}
private ArrayList<HashMap<String, ActivityInfo>> convertToＷordArrayList(String jsonStr){
JSONObject jsonObject ;
ArrayList<HashMap<String, ActivityInfo>> arrayList = new ArrayList<HashMap<String, ActivityInfo>>();
try{
jsonObject = new JSONObject(jsonStr);
JSONArray jsonArray=jsonObject.getJSONArray("article");
for (int i=0;i<jsonArray.length();i++){
JSONObject jsonObjRow=jsonArray.getJSONObject(i);
ActivityInfo activityInfo =new ActivityInfo();
activityInfo.eventName = jsonObjRow.getString("eventName");
activityInfo.date = jsonObjRow.getString("date");
HashMap<String, String> map= new HashMap<String, ActivityInfo>();
map.put("eventName", activityInfo.eventName );
map.put("date", activityInfo.date);
JSONArray jsonArray2=jsonObjRow.getJSONArray("content");
for (int j=0;j<jsonArray2.length();j++) {
JSONObject jsonObjRow2 = jsonArray2.getJSONObject(j);
activityInfo.review = jsonObjRow2.getString("review");
}
arrayList.add(activityInfo);
}
}catch (JSONException e){
e.printStackTrace();
}
return arrayList;
}
ActivityInfo class (using the serializable to got the result )
public class ActivityInfo implements Serializable {
String eventName;
String date ;
public void setEventName(String eventName){
this.eventName =eventName ;
}
public String toString(){
return this.eventName;
}
}
Json Response is no problem
{
"article":[
{
"activityId":"5c5d8addd404c",
"eventName":"running",
"date":"2019-02-08",
"content":[
{
"review":"you there"
},
{
"review":"please go away"
},
]
},
{
"activityId":"5c5d8b318df62",
"eventName":"basketball",
"date":"2019-02-13",
"content":[
{
"review":"confirm again"
}
]
},
{
"activityId":"5c5d8b9308018",
"eventName":"playing",
"date":"2019-02-16",
"content":[
{
"review":"provid of you"
}
]
}
]
}

I totally do it like this:
public class menuCreation()
{
public string Category { get; set; }
public string ItemName { get; set; }
public string Price { get; set; }
public string FileName { get; set; }
public menuCreation[] Arr { get; set; }
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
string json = (reader.ReadToEnd());
List<menuCreation> items = JsonConvert.DeserializeObject<List<menuCreation>>(json);
Arr = items.ToArray();
}
menuCreation mc = new menuCreation();
foreach (var item in mc.Arr)
{
PictureBox pb = new PictureBox();
pb.Tag = item.ItemName;
pb.Name = item.Price;
}
You can see, I reach itemName with class object.So, you can add listview with this method.

This is your Model Class..
ActivityInfo.java
public class ActivityInfo implements Serializable {
String eventName;
String date;
public void setEventName(String eventName){
this.eventName = eventName ;
}
public String getEventName(){
return this.eventName;
}
public void setDate(String date){
this.date = date;
}
public String getDate(){
return date;
}
}
This will be your final errorfree code..
private void displayArrayList(String jsonStr){
String[] from = {"eventName", "date"};
int[] to = {R.id.eventName, R.id.date};
SimpleAdapter simpleAdapter = new SimpleAdapter (
getActivity(),convertToＷordArrayList(jsonStr), R.layout.listview_layout,from,to);
simpleAdapter.notifyDataSetChanged();
listView.setAdapter(simpleAdapter);
}
private ArrayList<HashMap<String,String>> convertToＷordArrayList(String jsonStr){
JSONObject jsonObject;
ArrayList<HashMap<String,String>> arrayList = new ArrayList();
try{
jsonObject = new JSONObject(jsonStr);
JSONArray jsonArray=jsonObject.getJSONArray("article");
for (int i=0;i<jsonArray.length();i++){
JSONObject jsonObjRow=jsonArray.getJSONObject(i);
HashMap<String,String> hashMap=new HashMap<>();//create a hashmap to store the data in key value pair
hashMap.put("eventName",jsonObjRow.getString("eventName"));
hashMap.put("date",jsonObjRow.getString("date"));
JSONArray jsonArray2=jsonObjRow.getJSONArray("content");
/*If you want to get Content Reviews from Json, you need to make another attributes like Content in ActivityInfo Class*/
arrayList.add(hashmap);
}
}catch (JSONException e){
e.printStackTrace();
}
return arrayList;
}

org.json.JSONException: Value OR-12345 at order_no of type java.lang.String cannot be converted to int

I am trying to populate the recycler view using json data from dummy api but it is not working. I have tried almost several solutions given in stack overflow.
Here is my code below:
public class loadOrdersList extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
ordersList = new ArrayList<>();
rvor = findViewById(R.id.recycler_view_orders);
rvor.setHasFixedSize(true);
rvor.setLayoutManager(new LinearLayoutManager(OrdersActivity.this));
}
#Override
protected void onPostExecute(Void aVoid) {
if (new CheckNetworkUtil(OrdersActivity.this).isNetworkAvailable()) {
Log.d("TEST", "------------------ordersList: " + ordersList.size());
OrdersAdapter adapter = new OrdersAdapter(getApplicationContext(), ordersList);
rvor.setAdapter(adapter);
srl.setRefreshing(false);
} else
Toast.makeText(OrdersActivity.this, "No Internet Connection!", Toast.LENGTH_SHORT).show();
}
#Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
}
#Override
protected Void doInBackground(Void... voids) {
try {
OkHttpClient client = new OkHttpClient();
final Request request = new Request.Builder()
.url("https://api.myjson.com/bins/la2gh")
.build();
Response responses = client.newCall(request).execute();
JSONArray orders = new JSONArray(responses.body().string());
ordersList = new ArrayList<>();
for (int i = 0; i < orders.length(); i++) {
JSONObject name = orders.getJSONObject(i);
String customerName = name.getString("customer_name");
String agentAssigned = name.getString("agent_assigned");
String orderId = name.getString("order_id");
Integer totalQuantity = name.getInt("total_quantity");
String orderDate = name.getString("order_date");
Integer orderNo = name.getInt("order_no");
String schoolYear = name.getString("school_year");
String company = name.getString("company");
String deliveryDate = name.getString("delivery_date");
String orderStatus = name.getString("order_status");
Integer grossRevenue = name.getInt("gross_revenue");
Integer netRevenue = name.getInt("net_revenue");
Integer totalOrdered = name.getInt("total");
Integer grandTotalOrdered = name.getInt("grand_total");
OrderModel orderModel = new OrderModel(customerName
,agentAssigned
,orderId
,totalQuantity
,orderDate
,orderNo
,schoolYear
,company
,deliveryDate
,orderStatus
,grossRevenue
,netRevenue
,totalOrdered
,grandTotalOrdered);
ordersList.add(orderModel);
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
}
I suspected that integer is not supported by the string during execution.

You are expecting order_no to be an Integer and thus written this
Integer orderNo = name.getInt("order_no");
But you are receiving an alphanumeric value for orderNo in recycler view.
So either you have to change the type of orderNo property of OrderModel from Integer to String or restrict values to Integer type only.

How do I combine two separate parsed jsonObjects into a single arraylist?

I would like to combine two separate parsed jsonObjects into a single arraylist, then display the results as Strings?
I would like to store summaryJsonObject & segment in storylineData. When I step through the code using the debugger summaryJsonObject & segment both hold the raw json. The raw json data also shows in the logcat but storylineData remains null & unavailable throughout.
Here is the parsing code.
public class StorylineData {
private static String date;
private ArrayList<SummaryData> summary;
private ArrayList<SegmentData> segments;
private String caloriesIdle;
private String lastUpdate;
public String getDate() {
return date;
}
public ArrayList<SummaryData> getSummary() {
return summary;
}
public ArrayList<SegmentData> getSegments() {
return segments;
}
public String getCaloriesIdle() {
return caloriesIdle;
}
public String getLastUpdate() {
return lastUpdate;
}
public void setDate(String date) {
this.date = date;
}
public void setSummary(ArrayList<SummaryData> summary) {
this.summary = summary;
}
public void setSegments(ArrayList<SegmentData> segments) {
this.segments = segments;
}
public void setCaloriesIdle(String caloriesIdle) {
this.caloriesIdle = caloriesIdle;
}
public void setLastUpdate(String lastUpdate) {
this.lastUpdate = lastUpdate;
}
public static StorylineData parse(JSONObject jsonObject) {
if (jsonObject != null) {
StorylineData storylineData = new StorylineData();
storylineData.date = jsonObject.optString("date");
storylineData.caloriesIdle = jsonObject.optString("caloriesIdle");
storylineData.lastUpdate = jsonObject.optString("lastUpdate");
storylineData.summary = new ArrayList<SummaryData>();
storylineData.segments = new ArrayList<SegmentData>();
JSONArray summariesJsonArray= jsonObject.optJSONArray("summary");
if (summariesJsonArray != null) {
for (int i = 0; i < summariesJsonArray.length(); i++) {
JSONObject summaryJsonObject = summariesJsonArray.optJSONObject(i);
if (summaryJsonObject != null) {
storylineData.summary.add(SummaryData.parse(summaryJsonObject));
Log.d("storylineHandler", summaryJsonObject.toString());
}
}
}
JSONArray segmentsJsonArray = jsonObject.optJSONArray("segments");
if (segmentsJsonArray != null) {
for (int i = 0; i < segmentsJsonArray.length(); i++) {
JSONObject segment = segmentsJsonArray.optJSONObject(i);
if (segment != null) {
storylineData.segments.add(SegmentData.parse(segment));
Log.d("storylineHandler", segment.toString());
}
}
}
return storylineData;
}
return null;

If you wanted to have one ArrayList to store both SummaryData and SegmentData, you could just created an ArrayList of Objects, ArrayList<Object>. This would be the more general solution.
The alternative would be having SummaryData and SegmentData inherit the same class or implement the same interface.
Using an extended class, you could have:
class Data {
}
class SegmentData extends Data {
}
class SummaryData extends Data {
}
You could then have an ArrayList that would be able to add both SegmentData and SummaryData objects.
If you wanted to show each item as a String you would need to loop through the list and call the toString() function of each item
ArrayList<Data> dataList;
for (Data d : dataList) {
Log.d("data", d.toString())
}
Just make sure to overwrite the toString() function in SegmentData and SummaryData
EDIT: Showing how to print JsonArray
If you wanted to just print for JsonArrays, you could:
public class StorylineData {
private static String date;
private JSONArray summary;
private JSONArray segments;
private String caloriesIdle;
private String lastUpdate;
public String getDate() {
return date;
}
public JSONArray getSummary() {
return summary;
}
public JSONArray getSegments() {
return segments;
}
public String getCaloriesIdle() {
return caloriesIdle;
}
public String getLastUpdate() {
return lastUpdate;
}
public void setDate(String date) {
this.date = date;
}
public void setSummary(JSONArray summary) {
this.summary = summary;
}
public void setSegments(JSONArray segments) {
this.segments = segments;
}
public void setCaloriesIdle(String caloriesIdle) {
this.caloriesIdle = caloriesIdle;
}
public void setLastUpdate(String lastUpdate) {
this.lastUpdate = lastUpdate;
}
public static StorylineData parse(JSONObject jsonObject) {
if (jsonObject != null) {
StorylineData storylineData = new StorylineData();
storylineData.date = jsonObject.optString("date");
storylineData.caloriesIdle = jsonObject.optString("caloriesIdle");
storylineData.lastUpdate = jsonObject.optString("lastUpdate");
storylineData.summary = jsonObject.optJSONArray("summary");
storylineData.segments = jsonObject.optJSONArray("segments");
return storylineData;
}
return null;
}
#Override
public String toString() {
JSONArray combined = new JSONArray(summary);
combined.put(segment);
return combined.toString();
}
}
In your MainActivity
private StorylineData storylineData;
private MovesHandler<JSONArray> storylineHandler = new MovesHandler<JSONArray>() {
#Override
public void onSuccess(JSONArray result) {
toggleProgress(false);
storylineData = StorylineData.parse(summaryJsonObject);
updateResponse(storylineData.toString()) //displays true to layout view
result.add(storylineData.getSummary());
Log.d("call result", result.toString());
Log.d("Log.d storylineHandler", storylineHandler.toString());
}
};

Array and Object JSON from URL Parsing

I was a novice at the json parsing from url. yesterday I've tried parsing json simple data. Now I am confused to form a json parsing the data as below. I still can not how to parse arrays and objects in json. Please help me guys ..
here my MainActivity.java

JSONObject jObject_Main= new JSONObject(jsonstring);
//get json simple string
String id = jObject_Main.getString("id");
String page = jObject_Main.getString("page");
//get json Array and parse it.

.getJSONArray("results");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String backdrop_path=jsonObject.getString("backdrop_path");
}
i hope its useful to you.

please change this in your code:
JSONObject json = parser.getJSONFromUrl(URL);
try {
id = json.getString("id");
page = json.getString("page");
tot_result = json.getJSONArray(results);
i hope you understand it.

Try this..
In your Global:
JSONArray results = null;
String id = null;
String page = null;
String pages = null;
String tot_result = null;
Inside Try Catch:
JSONObject json = parser.getJSONFromUrl(URL);
try {
id = json.getString(TAG_ID); // Changes here
page = json.getString(TAG_page); // Changes here
pages = json.getString(TAG_total_pages); // Changes here
tot_result = json.getString(TAG_total_results); // Changes here
results = json.getJSONArray(TAG_results); // Add this line
for (int i = 0; i < results.length(); i++) {
// Remaining all correct
}
EDIT:
new DownloadImageTask()
.execute("your image url");
}
and DownloadImageTask.class
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
protected Bitmap doInBackground(String... urls) {
String urldisplay = urls[0];
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return mIcon11;
}
protected void onPostExecute(Bitmap result) {
imageview.setImageBitmap(result);
}
}

Your JSON is JSONObject and it contains JSONArray
Parse Object
Parse Array
Example:
JSONObject jsonObj = new JSONObject(your_json_string);
String id = jsonObj.getString("id");
String page = jsonObj.getString("page"); // or getInt("page");
JSONArray results = jsonObj.getJSONArray("results");
int len = results.length(); // length or size, I don't remember, you can check it
for (int i = 0; i < len; i++) {
JSONObject obj = results.getJSONObject(i);
String backdropPath = obj.getString("backdrop_path");
// ...
}

you need add " results= json.getJSONArray(TAG_results);" below
"tot_result = json.getJSONArray(TAG_total_results);"
