Am пытается сделать ListView с помощью залпа я не получает ответ от сервера он выдает ошибку JSONException это мой ответ от сервера:Не получать ответ от сервера при использовании volley для listview?
[{"UserName":"XXXX ","TaskID":1,"Subject":"fjsdgfgf","DueDate":"2016-01-06T00:00:00","Priority":0,"Owner":762,"OwnerName":null,"RepeatStatus":false,"TaskStatus":"In Progress","RelatedTo":null},{"UserName":"XXX","TaskID":2,"Subject":"test","DueDate":"2016-01-11T00:00:00","Priority":0,"Owner":762,"OwnerName":null,"RepeatStatus":false,"TaskStatus":"Not Started","RelatedTo":null}]
я не получает ответ он прямо идет к Onerrorresponse он бросает типа Java. lang.String не может быть преобразован в JSONArray, как новичок я действительно путает, где я сделать ошибку до сих пор, что я попробовал это:
Это фрагмент, где я сделать запрос залпа:

@Override

Это моя модель класса:
public class Model_Task_List {
public String UserName;
public String Subject;
public String TaskStatus;
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(){
}
}
Мои Jsonresponse:
[{"UserName":"XXXXXX ","TaskID":1,"Subject":"fjsdgfgf","DueDate":"2016-01-06T00:00:00","Priority":0,"Owner":762,"OwnerName":null,"RepeatStatus":false,"TaskStatus":"In Progress","RelatedTo":null},{"UserName":"XXXXX","TaskID":2,"Subject":"test","DueDate":"2016-01-11T00:00:00","Priority":0,"Owner":762,"OwnerName":null,"RepeatStatus":false,"TaskStatus":"Not Started","RelatedTo":null}]
Я не знаю, где я могу сделать ошибку кто-нибудь helpme !!!

разместить Ваш jsonarray залп metthod –
это в классе фрагмента –
вы получаете ответ от залпа. вы получаете JSONException во время разбора – Pr38y
