这是我的JSON输出：

{
"Message": [
    {
        "Emp_Id": 7,
        "Emp_First_Name": "Mohammad",
        "Emp_Last_Name": "Malek",
        "Emp_Email": "malek@cloudester.com",
        "Emp_Address": "A-82/2,Ahmed nagar Society, Manubar Road, Bharuch-392001",
        "Emp_Phone_No": "8140717602",
        "Emp_Password": "3f645aeff486fd9bda7ded484a43f701",
        "Emp_Photo": "/Images/2018_07_02_05_30_24.jpg",
        "Is_Resign": 0,
        "Joining_Date": "2017-12-12T00:00:00.000Z",

        "sms_status": 0
    }

这是我的pojo课：

    this.empLastName=empLastName;
    this.empEmail=empEmail;

public String getMessage() {
    return message;

public User getUser() {

当调用oncreateview时，它将变为onfailure，并且如上所示烘烤消息。 我做错了任何帮助，我们将不胜感激。

使此pojo类像.. 

public class MessageItem{

@SerializedName("Emp_Id")
private int empId;

@SerializedName("Emp_Email")
private String empEmail;

@SerializedName("Emp_First_Name")
private String empFirstName;

@SerializedName("Emp_Address")

@SerializedName("Resign_Date")
private String resignDate;

@SerializedName("Emp_Phone_No")
private String empPhoneNo;

@SerializedName("Emp_Password")
private String empPassword;

@SerializedName("sms_status")
private int smsStatus;

public void setEmpId(int empId){
    this.empId = empId;
}

public int getEmpId(){
    return empId;
}

public void setEmpEmail(String empEmail){
    this.empEmail = empEmail;
}

public String getEmpEmail(){
    return empEmail;
}

public void setEmpFirstName(String empFirstName){
    this.empFirstName = empFirstName;
}

public String getEmpFirstName(){
    return empFirstName;
}

public void setEmpAddress(String empAddress){
    this.empAddress = empAddress;
}

public String getEmpAddress(){
    return empAddress;
}

public void setJoiningDate(String joiningDate){
    this.joiningDate = joiningDate;
}

public String getJoiningDate(){
    return joiningDate;
}

public void setIsResign(int isResign){
    this.isResign = isResign;
}

public int getIsResign(){
    return isResign;
}

public void setEmpLastName(String empLastName){
    this.empLastName = empLastName;
}

public String getEmpLastName(){
    return empLastName;
}

public void setEmpPhoto(String empPhoto){
    this.empPhoto = empPhoto;
}

public String getEmpPhoto(){
    return empPhoto;

public void setResignDate(String resignDate){
    this.resignDate = resignDate;

} 

public class ResponseData {

@SerializedName("Message")
private List<MessageItem> message;

public void setMessage(List<MessageItem> message){
    this.message = message;
}

public List<MessageItem> getMessage(){
    return message;
}

}

在那之后.. 

 Call<ResponseData>

收到类似

的回复时 
        call.enqueue(new Callback<ResponseData>() {
        @Override
        public void onResponse(Call<ResponseData> call, Response<ResponseData> response) {
            //.getMessage is POJO method to listen for final json output

            if (response.isSuccessful() && response!=null && response.body()!=null){
                List<MessageItem> message=response.body().getMessage();
                if (message!=null && !message.isEmpty()){
                    for(MessageItem messageItem:message){
                        etfname.setText(messageItem.getEmpFirstName());
                        etlname.setText(messageItem.getEmpLastName());
                        //same for others

                    }
                }
            }
        }

        @Override
        public void onFailure(Call<Result> call, Throwable t) {
            progressDialog.dismiss();
            Toast.makeText(getActivity(), t.getMessage(), Toast.LENGTH_LONG).show();
        }
    });

检查您的Result类。 Message是数组，而不是String。 要从Json生成对象，请转到http://pojo.sodhanalibrary.com/并粘贴您的Json。
