Java 对listview使用截击时未从服务器获得响应？

我正在尝试使用截图创建listview我没有从服务器得到响应它抛出错误JSONException这是我从服务器得到的响应：

[{“用户名”：“XXXX”，“任务ID”：1，“主题”：“fjsdgfgf”，“DueDate”：“2016-01-06T00:00:00”，“优先级”：0，“所有者”：762，“所有者姓名”：null，“重复状态”：false，“任务状态”：“进行中”，“相关到”：null}，{“用户名”：“XXX”，“任务ID”：2，“主题”：“测试”，“DueDate”：“2016-01-11T00:00:00”，“优先级”：0，“所有者”：762，“所有者姓名”：null，“重复状态”：false，“任务状态”：“未启动”，“相关到”：null}]

我没有得到响应，它直接转到它抛出的类型为java.lang.String的Onerrorresponse，无法转换为JSONArray，因为初学者我真的很困惑，我犯了什么错误，到目前为止，我尝试的是：

这是我发出截击请求的片段：

我的回答：

我认为您从string得到的响应是string。请在服务器端进行交叉验证

发布你的jsonarray截击会议它在片段类中你从截击中得到响应。当我调试我的应用程序时，它直接进入错误部分发布你的日志输出这不是jsonarray？那么我可以继续吗？或者需要看一下它吗？汉克斯，让我先检查一下，但如果你看到t我在上面发布的回复看起来像jsonarray，那么为什么我会变成这样呢

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(){

    }
}
