Not getting the proper response from retrofit api call-CodePudding

I'm using retrofit API to get data, and for that, I've created the POJO classes as required.

Here are my POJO classes, 1. Report

@SerializedName("success")
@Expose
private Boolean success;
@SerializedName("data")
@Expose
private List<Datum> data = null;

public Boolean getSuccess() {
    return success;
}

public void setSuccess(Boolean success) {
    this.success = success;
}

public List<Datum> getData() {
    return data;
}

public void setData(List<Datum> data) {
    this.data = data;
}

Datum

Here is how I tried to fetch the data in form of a Datum list using the Report class.

Here is the activity code...

Call<Report> call = RetrofitClient
                    .getInstance()
                    .getApi()
                    .getAlltheReports(reportModel);


            call.enqueue(new Callback<Report>() {
                @Override
                public void onResponse(Call<Report> call, Response<Report> response) {

                    Log.d("responseBodyyyyyyyyy", String.valueOf(response.body()));

                    Report example = response.body();

                    if (example != null) {
                        Log.d("gettingNull", "DATA");

                        List<Datum> data = response.body().getData();
                        Log.d("dataaaaaaaaaaaaaaaa", String.valueOf(data));


                    } else {
                        Log.d("gettingNull", "Null");
                    }
                }

                @Override
                public void onFailure(Call<Report> call, Throwable t) {
                    Log.d("error", String.valueOf(t));
                }
            });

In, the retrofit call reportModel is nothing but JSON data.

For reference,

ReportModel:

ReportModelJson reportModel = new ReportModelJson("353081090133664", "Asia/Kolkata", "02-06-2022", "02-10-2022");

And I'm posting the API call like this:-

@POST("getonlyselect")
Call<Report> getAlltheReports(
        @Body ReportModelJson ReportModelJson
);

This is I tried to fetch the data, but instead of getting the proper response, I'm getting the packagename@xxxx.

For reference:

com.example.abcd.Screens.Models.Datum@42df5e8

The response that I'm getting is like this:-

{
"success": true,
"data": [
    {
        "_id": "61fed1d527824e063e318124",
        "seq": 21,
        "imei": "353081090133664",
        "lat": "22.472927",
        "lon": "70.080795",
        "etype": "stop",
        "nos": "5",
        "rssi": "-51",
        "hac": "1.5",
        "spd": "2",
        "btv": "12.34",
        "address": "abcd",
        "dt": "1644089809000",
        "erpm": "N",
        "thpos": "N",
        "erntm": "N",
        "fgrl": "N",
        "dtml": "N",
        "flvl": "N",
        "ftype": "N",
        "eot": "N",
        "ect": "N",
        "odm": "N",
        "date": "2022-02-05T19:36:53.087Z",
        "__v": 0
    }
]

}

Please help me to find out the solution.

CodePudding user response：

As I understand your code, there is not any error in the retrofit API call, There is an error in the printing value that you got from API.

As I can see in your code you have used the below code to print data that you got from API.

List<Datum> data = response.body().getData();
 Log.d("dataaaaaaaaaaaaaaaa", String.valueOf(data));

Also, Data is an array that you are trying to print using Log.d. So if you want to print your data so you can set for loop to print every object data like below.

List<Datum> data = response.body().getData();
for(int l=0; l<data.size(); l  )
{
  Log.d("dataaaaaaaaaaaaaaaa", data.get(l)._id())
 }

I hope, this will help you to solve your issue.
