从服务器接收对象而不是字符串？

Question

我试图用凌空连接服务，并绑定该值微调器，但是当我试图设置适配器显示没有得到字符串对象的值不知道在哪里我会犯错，这是我的代码：

final Spinner spinner=(MaterialSpinner)findViewById(R.id.spinner); 
     String Url = "http://xxx.xx.xx.xxx/xxx/CRM/AcoountCreatePageLoad.svc/Account/AccountPageLoad"; 
     JsonObjectRequest jsonObjRequest = new JsonObjectRequest(Request.Method.GET, Url, new JSONObject(), 
       new Response.Listener<JSONObject>() { 

        @Override 
        public void onResponse(JSONObject response) { 
         String server_response = response.toString(); 
         try { 
          JSONObject json_object = new JSONObject(server_response); 
          JSONArray json_array = new JSONArray(json_object.getString("AccountPageLoadResult")); 
          for (int i = 0; i < json_array.length(); i++) { 
           Model_Spinner_yog model_spinner_yog = new Model_Spinner_yog(); 
           JSONObject json_arrayJSONObject = json_array.getJSONObject(i); 
           model_spinner_yog.setName(json_arrayJSONObject.getString("Name")); 
           yog.add(model_spinner_yog); 



          } 

          ArrayAdapter<Model_Spinner_yog> yogs=new ArrayAdapter<Model_Spinner_yog>(Create_Account.this, android.R.layout.simple_spinner_dropdown_item,yog); 
          spinner.setAdapter(yogs); 
         } catch (JSONException e) { 
          e.printStackTrace(); 
         } 

我模型类：

public class Model_Task_List implements Serializable { 


    public int getId() { 
     return id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    public Model_Task_List(int id, String subject, String userid, String taskStatus, int taskID, String userName) { 
     this.id = id; 
     Subject = subject; 
     TaskID = taskID; 
     TaskStatus = taskStatus; 
     this.userid = userid; 
     UserName = userName; 
    } 

    public int id; 
    public String UserName; 
    public String Subject; 
    public String TaskStatus; 

    public int getTaskID() { 
     return TaskID; 
    } 

    public void setTaskID(int taskID) { 
     TaskID = taskID; 
    } 

    public int TaskID; 
    public static String KEY_table="task"; 
    public static String KEY_id="id"; 
    public static String KEY_username="name"; 
    public static String KEY_subject="subject"; 
    public static String KEY_task="status"; 
    public static String KEY_taskid="taskid"; 
    public static String KEY_owner="owner"; 

    public String getUserid() { 
     return userid; 
    } 

    public void setUserid(String userid) { 
     this.userid = userid; 
    } 

    public String userid; 

    public String getSubject() { 
     return Subject; 
    } 

    public void setSubject(String subject) { 
     Subject = subject; 
    } 

    public String getTaskStatus() { 
     return TaskStatus; 
    } 

    public void setTaskStatus(String taskStatus) { 
     TaskStatus = taskStatus; 
    } 

    public String getUserName() { 
     return UserName; 
    } 

    public void setUserName(String userName) { 
     UserName = userName; 
    } 

    public Model_Task_List(String subject, String taskStatus, String userName) { 
     Subject = subject; 
     TaskStatus = taskStatus; 
     UserName = userName; 
    } 
    public Model_Task_List(){ 

    } 
} 

响应：

根据你的回应，你应该不会再次转换成字符串，则T o JSONObject。使用下面的代码作为参考，然后重新编写代码。

@Override 
    public void onResponse(JSONObject response) { 
     if(response != null){ 
     JSONArray array = response.optJSONArray("AccountPageLoadResult"); 
     for(int i = 0; i<array.length();i++){ 
      JSONObject object = array.optJSONObject(i); 
      // get Other data from object using optString("name") or getString("name") 
     } 
     } 
    }
