I am new to Retrofit and built a simple app using it. But when I tried to run the app, it didn't display the data fetched from the web. However, the api hits are increasing each time. Kindly help me solve this out. Thanks in advance.
Main Activity:
package com.vyshnav.trainname;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
// API KEY: iqccq8931
// TODO - insert your themoviedb.org API KEY here
private final static String API_KEY = "iqccq8931";
private final static String TRAIN_NAME = "BHOPAL EXPRESS";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (API_KEY.isEmpty()) {
Toast.makeText(getApplicationContext(), "Please obtain your API KEY first from themoviedb.org", Toast.LENGTH_LONG).show();
return;
}
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
Call<TrainNameResponse> call = apiService.getTrainNameResponse(TRAIN_NAME,API_KEY);
call.enqueue(new Callback<TrainNameResponse>() {
@Override
public void onResponse(Call<TrainNameResponse>call, Response<TrainNameResponse> response) {
// Class<Train> trainObj = response.body().getTrain();
String tv1 = response.body().getTrain().getName();
TextView textView = (TextView) findViewById(R.id.tv1);
textView.setText(tv1);
int tv2 = response.body().getResponse_code();
TextView textView2 = (TextView) findViewById(R.id.tv2);
textView2.setText(tv2);
}
@Override
public void onFailure(Call<TrainNameResponse>call, Throwable t) {
// Log error here since request failed
}
});
}
}
ApiClient.java
package com.vyshnav.trainname.rest;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class ApiClient {
public static final String BASE_URL = "http://api.railwayapi.com/name_number/";
private static Retrofit retrofit = null;
public static Retrofit getClient() {
if (retrofit==null) {
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)

return retrofit;

public interface ApiInterface {
@GET("train/{name}/apikey/{apikey}/")
Call<TrainNameResponse> getTrainNameResponse(@Path("name") String name, @Path("apikey") String apiKey);
}
TrainNameResponse.java
package com.vyshnav.trainname.model;

public class TrainNameResponse {
@SerializedName("train")
Class<Train> train;
@SerializedName("response_code")

this.train = train;
}
public int getResponse_code() {
return response_code;
}
public void setResponse_code(int response_code) {
this.response_code = response_code;
}
}
Train.java
package com.vyshnav.trainname.model;
import com.google.gson.annotations.SerializedName;
import java.util.List;
public class Train {
@SerializedName("days")

Days.java
package com.vyshnav.trainname.model;
import com.google.gson.annotations.SerializedName;
public class Days {
@SerializedName("runs")

@SerializedName("day-code")
private String daycode;
public Days (String runs,String daycode) {
this.runs = runs;
this.daycode = daycode;
}
public String getRuns() {
return runs;
}
public void setRuns(String runs) {
this.runs = runs;
}
public String getDaycode() {

}
public void setDaycode(String daycode) {

}
}
Why are only some getters and setters coloured in orange while some others are not?
Also I found 2 issues in logcat though the app is not crashing. Logcat:
