Fang JsonArray Antwort mit Volley für Android

Question

Ich versuche, Zeichenfolge von JsonArrayRequest sammeln, aber ich war nicht in der Lage, dies zu tun. Ich bekomme Fehler wie folgt

Dies ist der Ausschnitt aus meinem Code ist

JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.POST, ITEM_CUSTOMER_MEASUREMENTS, null, 
        new Response.Listener<JSONArray>() { 
         @Override 
         public void onResponse(JSONArray response) { 

          try { 
           JSONObject jsonobject = new JSONObject(); 

           String shoulder = jsonobject.getString("shoulder"); 
           et_shoulder.setText(shoulder); 
           String arm_hole = jsonobject.getString("arm_hole"); 
           et_arm_hole.setText(arm_hole); 

           String chest_1 = jsonobject.getString("chest_1"); 
           et_chest_1.setText(chest_1);

           et_b_neck.setText(b_neck); 

           String sleeve_length = jsonobject.getString("sleeve_length"); 
           et_sleeve_length.setText(sleeve_length); 

           String sleeve_breadth = jsonobject.getString("sleeve_breadth"); 
           et_sleeve_breadth.setText(sleeve_breadth);

           et_thigh.setText(thigh); 


           Log.d("response", "onResponse: " +shoulder +arm_hole +chest_1 +chest_2 +hip +slit +top_length +f_neck +b_neck +sleeve_length 
             +sleeve_breadth +sleeve_type +hip_size +ankle +bottom_length +knee +bottom_breadth +thigh); 


          } catch (JSONException e) { 
           e.printStackTrace(); 
          } 

         } 
        }, 
        new Response.ErrorListener() { 
         @Override 
         public void onErrorResponse(VolleyError error) { 
         } 
        }){ 
       @Override 
       public Map<String, String> getHeaders() throws AuthFailureError { 
        Map<String,String> headers = new HashMap<>(); 
        headers.put("Authorization", api_token); 
        headers.put("X-Request-ID", cust_id); 
        headers.put("X-Requested-With", item_type); 

        Log.d("heade values", "getHeaders: " +api_token+" "+cust_id+" "+item_type); 
        return headers; 
       } 
      }; 

      //Creating request queue 
      RequestQueue requestQueue = Volley.newRequestQueue(ItemsFragment.this.getActivity()); 

      //Adding request to the queue 
      requestQueue.add(jsonArrayRequest); 

Kann mir jemand sagen, was mit dem Code nicht stimmt.Dies ist, wie die Antwort vom Server sieht wie

[ { "id": 3, "order_id": 3, "employee_id": 1, "item_type": 8, "Schulter" "", "arm_hole:": "", "chest_1": "", "chest_2": "", "Taille": "", "hip": "", "geschlitzt": " ", " top_length ":" ", " f_neck ":" ", " b_neck ":" ", " sleeve_length ":" ", "sleeve_breadth": "", "sleeve_type": "", "hip_size": "38", "Knöchel": "", "bottom_length": "70", "Knie": "", "bottom_breathth": "60", "Oberschenkel": "", "Beschreibung": "Test", "Betrag": 5000, "created_at": "2016-12-22 06:38:01" , "updated_at": "2016.12.22 06.38.01" "customer_id": 1, "item_id": 3 } ]

Answer 1

diesen Teil geändert:

public void onResponse(JSONArray response) { 

     try { 
      JSONArray jsonobect = new JSONArray(); 

zu

JSONObject jsonobject = response.getJSONObject(0);
