Comment poster JSON en volley en utilisant android?

Question

Je travaille sur Volley mais je suis assez nouveau pour ce framework je n'ai aucune idée de comment publier des données JSON en utilisant volley, j'ai un exemple JSON s'il vous plaît dites-moi comment publier ces données JSON.

JSONObject jsonObject = new JSONObject(); 
jsonObject.put("email", "abcd@g.com"); 
jsonObject.put("password", "abcd123"); 
jsonObject.put("device", "jdghfdhgdhi"); 
jsonObject.put("latitude", 1.2456); 
jsonObject.put("longitude", 1.3466);

essayez ceci:

StringRequest stringRequest = new StringRequest(Request.Method.POST, your url, 
        new Response.Listener<String>() { 
         @Override 
         public void onResponse(String response) { 
          try { 

          } catch (JSONException e) { 
           e.printStackTrace(); 
          } 
         } 
        }, 
        new Response.ErrorListener() { 
         @Override 
         public void onErrorResponse(VolleyError error) { 
          Toast.makeText(NoolReaderDashboard.this, error.toString(), Toast.LENGTH_LONG).show(); 
         } 
        }) { 
       @Override 
       protected Map<String, String> getParams() { 
        Map<String, String> params = new HashMap<String, String>(); 
      params .put("email", "abcd@g.com"); 
     params .put("password", "abcd123"); 
     params .put("device", "jdghfdhgdhi"); 
     params .put("latitude", 1.2456); 
     params .put("longitude", 1.3466); 
        return params; 
       } 
      }; 
      RequestQueue requestQueue = Volley.newRequestQueue(this); 
      requestQueue.add(stringRequest);

privé vide Postdata() {

String url = "http://www.example.com";        //url where you want to post data 
    StringRequest postRequest = new StringRequest(Request.Method.POST, url, 
      new Response.Listener<String>() { 
       @Override 
       public void onResponse(String response) { 
        try { 
         Log.i("response is","==>"+response); 

        } catch (JSONException e) {

     protected Map<String, String> getParams() { 
      Map<String, String> params = new HashMap<>();

     final JsonObjectRequest postRequest = new JsonObjectRequest(Request.Method.POST, url, jsonObject, new Response.Listener<JSONObject>() { 
       @Override 
       public void onResponse(JSONObject response) { 


// here parse your response json data 

        try {

        // Handle your error types accordingly.For Timeout & No connection error, you can show 'retry' button. 
        // For AuthFailure, you can re login with user credentials. 
        // In this case you can check how client is forming the api and debug accordingly. 
        // For ServerError 5xx, you can do retry or handle accordingly. 
        if (error instanceof NetworkError) {
