i have to inflate listview with the Json data with parameters . But it gives error 2.onErrorResponse: MainActivity . I checked multiple times with String Request and Json Request but none of them is working... Please Help!!!
JsonArrayRequest movieReq = new JsonArrayRequest(Request.Method.POST,url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
title_array.add(obj.getString("amount").toString());
notice_array.add(obj.getString("payment_id").toString());
title1_array.add(obj.getString("invoice_id").toString());
notice1_array.add(obj.getString("payment_date").toString());
notice2_array.add(obj.getString("movieName").toString());
notice3_array.add(obj.getString("source").toString());
adapter = new CustomBaseAdapter(Transaction.this, title_array, notice_array,title1_array,notice1_array,notice2_array,notice3_array);
list.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();

Hi I am using volley as JSON Parsing. I am using POST method and sending parameters in post request. I am getting following error when parsing the data, I am getting following error. I want to use volley. I have tried with JsonArrayRequest but it does not allow to send parameters as JSONObject,which I am using in my code.
org.json.JSONArray cannot be converted to JSONObject
Request is like
{
"city":"acd",
"user_id":"82",
"phone_number1":"1232131231",
"my_type":"asf"
}
Response is like
[{
"name":"dfdfd",
}]
Following is my code
private void Search_Refer() {
//initialize the progress dialog and show it
progressDialog = new ProgressDialog(SearchReferNameActivity.this);
progressDialog.setMessage("Please wait....");
progressDialog.show();
try {
JSONObject jsonBody = new JSONObject();
jsonBody.put("city", "acb");
jsonBody.put("user_id", "82");
jsonBody.put("phone_number1", "12332123231");
jsonBody.put("my_type", "asf");
JsonObjectRequest jsonOblect = new JsonObjectRequest(Request.Method.POST, Constants.BASE_URL1+"api/lab/search", jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Toast.makeText(getApplicationContext(), response.toString(), Toast.LENGTH_LONG).show();
Log.e("Search EROOR", response.toString());
try {
JSONArray itemArray=new JSONArray(response);
dataModelArrayList = new ArrayList<>();
for (int i = 0; i < itemArray.length(); i++) {
SearchModel playerModel = new SearchModel();
JSONObject dataobj = itemArray.getJSONObject(i);
//playerModel.setProduct_name(dataobj.getString("name"));
playerModel.setRadiology_store_first_name(dataobj.getString("radiology_store_first_name"));
dataModelArrayList.add(playerModel);
}
} catch (JSONException e) {
e.printStackTrace();
}
progressDialog.dismiss();
/* Intent intent = new Intent(SearchReferNameActivity.this, SearchResult.class);
intent.putExtra("Search_result", dataModelArrayList);
startActivity(intent);*/
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), "Response: " + error.toString(), Toast.LENGTH_SHORT).show();
System.out.println("Search Eroor"+error.toString());
progressDialog.dismiss();
}
}){
#Override
public String getBodyContentType() {
return "application/json";
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Authorization", "Bearer "+deviceToken);
return headers;
}
};
jsonOblect.setRetryPolicy(new DefaultRetryPolicy(
10000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
MyApplication.getInstance().addToRequestQueue(jsonOblect,"postrequest");
} catch (JSONException e) {
e.printStackTrace();
}
// Toast.makeText(getApplicationContext(), "done", Toast.LENGTH_LONG).show();
}
Use JsonArrayRequest or StringRequest in place of JsonObjectRequest
JsonArrayRequest
change the following response parameter to JSONArray
Instead of new Response.Listener<JSONObject> Use new Response.Listener<JSONArray>
// JSONArray insated of JSONObject
public void onResponse(JSONArray response) {
}
Use Below code
StringRequest stringRequest = new StringRequest(Request.Method.POST, "api/lab/search", new Response.Listener<String>() {
#Override
public void onResponse(String response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("city", "abcd");
params.put("user_id", "82");
params.put("phone_number1", "01235467895");
params.put("my_type", "asf");
return params;
}
};
I have a web service which gives data in JSON array format. Right now the data is being fetched just by passing the URL. But now I want to pass a parameter to get the JSON response. This web service has GET & POST methods.
I tried with Volley - Sending a POST request using JSONArrayRequest answer, but I couldn't implement it in my code. It would be really helpful if somebody could explain, how to achieve this in my code.
This is how my code looks like
String HTTP_SERVER_URL = "https://192.168.1.7/STUDENTWS/Default.asmx/StudentDataJson?InFacultyID=string";
public void JSON_WEB_CALL(){
//mSwipeRefreshLayout.setRefreshing(true);
jsonArrayRequest = new JsonArrayRequest(HTTP_SERVER_URL,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
JSON_PARSE_DATA_AFTER_WEBCALL(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue = Volley.newRequestQueue(this);
requestQueue.add(jsonArrayRequest);
}
public void JSON_PARSE_DATA_AFTER_WEBCALL(JSONArray array){
for(int i = 0; i<array.length(); i++) {
DataModel GetDataModel = new DataModel();
JSONObject json = null;
try {
json = array.getJSONObject(i);
GetDataModel.setId(json.getString("STUDENTID"));
GetDataModel.setPlateNo(json.getString("GRADE"));
GetDataModel.setPlateCode(json.getString("HOUSE"));
}
catch (JSONException e)
{
e.printStackTrace();
}
DataAdapterClassList.add(GetDataModel);
mSwipeRefreshLayout.setRefreshing(false);
}
recyclerViewadapter = new NewRecyclerViewAdapter(DataAdapterClassList, this);
recyclerView.setAdapter(recyclerViewadapter);
if (array.length()!=0) {
SHOW_ALERT(array);
sendNotification(recyclerView, array);
}
}
For get with params you should create StringRequest. For example:
RequestQueue queue = Volley.newRequestQueue(context);
StringRequest sr = new StringRequest(Request.Method.GET, "http://headers.jsontest.com/",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.e("HttpClient", "success! response: " + response.toString());
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("HttpClient", "error: " + error.toString());
}
})
{
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("user","YOUR USERNAME");
params.put("pass","YOUR PASSWORD");
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<String, String>();
params.put("Content-Type","application/x-www-form-urlencoded");
return params;
}
};
// for json object
Map<String, String> jsonParams = new HashMap<String, String>();
jsonParams.put("fullname",fullName);
jsonParams.put("email",email);
jsonParams.put("password",password);
// for json array make any list.List will be converted to jsonArray
// example-----
// ArrayList<String> jsonParams =new ArrayList();
// jsonParams.add("Test1")
// jsonParams.add("Test2")
JsonObjectRequest objectRequest=new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "onErrorResponse: ",error );
Toast.makeText(ActivitySignUp.this,error.getMessage(), Toast.LENGTH_LONG).show();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String,String> header=new HashMap<String, String>();
header.put("Content-Type","application/json");
return header;
}
};
If you want to pass a param to your server, then you might wanna do a POST method, else.. if you only wanted to get the data, then GET method is the best way... there's also header that you can use to pass data, but, I wouldn't recommend to use header for sending params... that's a sore eyes
Edit
//Set you method POST or GET
JsonObjectRequest(Request.Method.GET(/*here can set to POST too*/), url, null,
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response) {
// display response
Log.d("Response", response.toString());
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
Log.d("Error.Response", response);
}
}
);
The code which does not work is below. See anything wrong with this code , why it is not sending parameters. I am new to Android.
private void sendParams()
{
JsonArrayRequest movieReq = new JsonArrayRequest(AppConfig.URL_Q_RECIPIES,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Recipie movie = new Recipie();
movie.setRecipieName(obj.getString("recipie_name"));
movie.setId(obj.getInt("id"));
// build the image URL here
String s = AppConfig.URL_IMAGE + obj.getInt("id") + ".jpeg";
movie.setImageURL(s);
movie.setPrimaryIngrediant(obj.getString("prim_ingr"));
movie.setUrl(obj.getString("url"));
// adding movie to movies array movie is nothing but recipie
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Filter error: " + error.getMessage());
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_LONG).show();
hidePDialog();
}
}) {
#Override
protected Map<String, String> getParams () {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("ind_ajwain", Integer.toString(session.isAjwainChecked()));
//params.put("ind_asaftide", Integer.toString(session.isAsaftideChecked()));
params.put("rec_name", "chicken"); /// change this
params.put("ind_ginger", "0");
//params.put("password", password);
return params;
}
};
Log.d(TAG, movieReq.toString());
//movieReq.
AppController.getInstance().addToRequestQueue(movieReq);
}
I followed this link to get coding don : Source: https://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/
I have not made much changes above, only changing parameters.
For sending data to server using Volley refer below code.
Step1 : Use POST method to send data.
Create below method :
private void makeJsonSend() {
StringRequest jsonObjReq = new StringRequest(Request.Method.POST,Const.ServiceType.URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.e("response:forgot", response);
jsonParseResponse(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//show error message here
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("email","email");
//pass parameter here
Log.i("request send data", params.toString());
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<>();
//If you have header parameter then set here
return headers;
}
};
AppController.getInstance().addToRequestQueue(movieReq);
}
Step 2: Response method where you have get response of that operation.
private void jsonParseResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
if (jsonObject.getString("status").equals("200")) {
cc.showToast(jsonObject.getString("message"));
} else {
cc.showToast(jsonObject.getString("message"));
}
} catch (JSONException e) {
e.printStackTrace();
Log.e("Forgot Error",e.toString());
}
}
You didn't pass any request method in new JsonArrayRequest. You have to pass Request.Method.POST or Request.Method.GET
Here is my code :
{
"VisitorDetails":[
{
"Name":"Ramesh",
"Gender":"Male",
"Age":24,
"MobileNo":9502230173,
"LandLine":"040140088",
"EmailId":"rameshkandula24#gmail.com",
"CreatedOn":"08-25-2016",
"Address":"Hyderabad",
"Profession":"Software",
"FamilyMembers":5,
"HomeTown":"Gannavaram",
"MedicalHealing":"Noooooo",
"Isinterestedwithcompanies":1,
"IsBetterlivingStandards":1,
"IsInterestedinConference":1,
"VisitorExcites":[1,2,3]
"jsonkey" : "rUinterested"
}
]
}
try {
JSONArray arry = new JSONArray();
JSONObject iner = new JSONObject();
iner.put("Name", "nmae");
//all detail to iner
arry.put(iner);
JSONObject outer = new JSONObject();
outer.put("VisitorDetails", arry);
}
catch (Exception e){
}
final JSONObject jsonObject=new JSONObject();
try {
JSONArray jsonArray=new JSONArray();
JSONObject innerobject=new JSONObject();
innerobject.put("Name",Name);
innerobject.put("Address",Country);
jsonArray.put(innerobject);
jsonObject.put("VisitorDetails",jsonArray);
}catch (Exception e){
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, URL,jsonObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// do something...
Toast.makeText(MainActivity.this, "your data successfully register", Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// do something...
Toast.makeText(MainActivity.this, "your data not register", Toast.LENGTH_SHORT).show();
}
}) {
/**
* Passing some request headers
*/
#Override
protected Map<String, String> getParams() {
Map<String, String> param = new HashMap<String, String>();
param.put("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
return param;
}
};
Update : add this in your gradle(app level)
compile 'com.android.volley:volley:1.0.0'
developing from Bansal ans .
your json data
JSONArray arry = new JSONArray();
try {
JSONObject jsonobject_one = new JSONObject();
jsonobject_one.put("Name", "Name");
// add all details like this
arry.put(jsonobject_one);
JSONObject jsonobject_TWO = new JSONObject();
jsonobject_TWO.put("VisitorDetails", arry);
}catch (JSONException e) {
e.printStackTrace();
}
Then Your jsonRequest
JsonArrayRequest jsonArryReq = new JsonArrayRequest(
Request.Method.POST,url, arry,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
}) {
/**
* Passing some request headers
* */
#Override
protected Map<String, String> getParams()
{
Map<String, String> param = new HashMap<String, String>();
if (!GetMethod) {
param.put("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
return param;
}
return param;
}
I'm using Volley to interact with an API. I need to send a post request with parameters to a service that returns a JSONArray.
I'm overriding the method protected Map<String, String> getParams() but it is not working:
JsonArrayRequest eventoReq = new JsonArrayRequest(Configuracion.URL_API_PROXIMOS_EVENTOS,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsea json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Evento evento = new Evento();
evento.setCod_evento(obj.getInt("cod_evento"));
evento.setTitulo(obj.getString("titulo"));
evento.setDescripcion(obj.getString("descripcion"));
evento.setDireccion(obj.getString("direccion"));
evento.setImagen(obj.getString("imagen"));
evento.setPuntuacion((float) obj.getDouble("puntuacion"));
// Añade el evento al listado
listaEventos.add(evento);
} catch (JSONException e) {
e.printStackTrace();
}
}
// Actualiza el adaptador
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
}){
#Override
protected Map<String, String> getParams() {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("tag", "eventos_proximos_usuario");
params.put("cod_usuario", cod_usuario);
return params;
}
#Override
public int getMethod() {
return Method.POST;
}
};
// Añade la peticion a la cola
AppController.getInstance().addToRequestQueue(eventoReq);
Try ...
StringRequest instead..
Reference:
https://android.googlesource.com/platform/frameworks/volley/+/master/src/main/java/com/android/volley/toolbox
JsonObjectRequest extends JsonRequest
whereas StringRequest extends Request
StringRequest eventoReq = new StringRequest(Request.Method.POST,Configuracion.URL_API_PROXIMOS_EVENTOS,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d(TAG, response.toString());
hidePDialog();
try{
JSONArray j= new JSONArray(response);
// Parsea json
for (int i = 0; i < j.length(); i++) {
try {
JSONObject obj = j.getJSONObject(i);
Evento evento = new Evento();
evento.setCod_evento(obj.getInt("cod_evento"));
evento.setTitulo(obj.getString("titulo"));
evento.setDescripcion(obj.getString("descripcion"));
evento.setDireccion(obj.getString("direccion"));
evento.setImagen(obj.getString("imagen"));
evento.setPuntuacion((float) obj.getDouble("puntuacion"));
// Añade el evento al listado
listaEventos.add(evento);
} catch (JSONException e) {
e.printStackTrace();
}
}
// Actualiza el adaptador
adapter.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
}){
#Override
protected Map<String, String> getParams() {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("tag", "eventos_proximos_usuario");
params.put("cod_usuario", cod_usuario);
return params;
}
};
// Añade la peticion a la cola
AppController.getInstance().addToRequestQueue(eventoReq);
Me just a beginner hope it helps!!!
try like this,
I think you don't need to override the getMethod() method.
Pass the method type (i.e Method.POST) name with in the JsonObjectRequest or JsonArrayRequest like below.
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
pDialog.hide();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
pDialog.hide();
}
}) {
#Override
protected Map<String, String> getParams() {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("tag", "eventos_proximos_usuario");
params.put("cod_usuario", cod_usuario);
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
I faced the same problem when I started to use Volley in my android project. I solved the problem by using StringRequest instead of JsonArrayRequest.
for example if you want to show a ListView with some server data...
Just use a simple StringRequest instead of JSONArrayRequest and implements the onResponse Methode like this :
public void onResponse(String response){
try{
JSONArray jsonArray=new JSONArray(response);
for(int i=0;i<jsonArray.length();i++) {
try {
JSONObject jsonObject = jsonArray.getJSONObject(i);
// do something
} catch (JSONException e) {
e.printStackTrace();
}
}
}catch (JSONException e2){
e2.printStackTrace();
}
}
}
StringRequest request = new StringRequest(Request.Method.POST, YourUrl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (!response.equals(null)) {
Log.e("Your Array Response", response);
} else {
Log.e("Your Array Response", "Data Null");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("error is ", "" + error);
}
}) {
//This is for Headers If You Needed
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json; charset=UTF-8");
params.put("token", ACCESS_TOKEN);
return params;
}
//Pass Your Parameters here
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("User", UserName);
params.put("Pass", PassWord);
return params;
}
};
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
queue.add(request);
