I want to fetch array values of users by calling API

I want to fetch array values of users by calling API - java

I want to fetch the array list of users. I have three POGO classes i.e Root(Parent class), ContactFamilyDetails(Child class), DataModelFamilyDetails(GrandChild class).
The problem that I have faced all the time that when I run the application at that time I only get the first array value, unfortunately, I didn't get the rest of the values. So I am going to share my whole code so please go through it and help me out of it !! Thank You!!

What am i doing wrong any help will appreciated.

Change your pojo class with this
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Example {
#SerializedName("Message")
#Expose
private List<Message> message = null;
public List<Message> getMessage() {

this.resignDate = resignDate;
}
public Integer getSmsStatus() {
return smsStatus;
}
public void setSmsStatus(Integer smsStatus) {
this.smsStatus = smsStatus;
}
}
than change your code with this
Call<Example> call = service.Bind_Employee_Details_Based_On_Id(emailtoken);
call.enqueue(new Callback<Example>() {
#Override
public void onResponse(Call<Example> call, Response<Result> response) {

String email=listResponse.get(0).getEmpEmail();
String address=listResponse.get(0).getEmpAddress();
String joindt=listResponse.get(0).getJoiningDate();
etfname.setText(fname);
etlname.setText(lname);
etemail.setText(email);
etaddress.setText(address);
etjoindt.setText(joindt);
progressDialog.dismiss();
}

Check your Result class. Message is Array, not a String.
To generate Object from Json, go to http://pojo.sodhanalibrary.com/ and paste your Json.

make this pojo class like ..
public class MessageItem{

#SerializedName("Is_Resign")
private int isResign;
#SerializedName("Emp_Last_Name")
private String empLastName;
#SerializedName("Emp_Photo")
private String empPhoto;
#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){

}
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){

}
public int getIsResign(){
return isResign;
}
public void setEmpLastName(String empLastName){

}
public void setEmpPhoto(String empPhoto){
this.empPhoto = empPhoto;
}
public String getEmpPhoto(){
return empPhoto;
}
public void setResignDate(String resignDate){
this.resignDate = resignDate;
}
public String getResignDate(){
return resignDate;
}
public void setEmpPhoneNo(String empPhoneNo){
this.empPhoneNo = empPhoneNo;
}
public String getEmpPhoneNo(){
return empPhoneNo;
}
public void setEmpPassword(String empPassword){
this.empPassword = empPassword;
}
public String getEmpPassword(){
return empPassword;
}
public void setSmsStatus(int smsStatus){
this.smsStatus = smsStatus;

#SerializedName("Message")
private List<MessageItem> message;
public void setMessage(List<MessageItem> message){
this.message = message;
}
public List<MessageItem> getMessage(){
return message;
}
}
after that ..
Call<ResponseData>
when you getting response like
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();
}
});

You should add to ItemObject :

Data from server is not displaying on screen

So am working with retrofit and rxjava for my application.so am using the #GET annociation to pull my blog details from the server that include blog_title, blog_content, blog_thumbnail etc and all this parameter are within an array called blog_post.
I have my APIClient:
public class ApiClient {
private static final String STAGING_BASE_URL = "https://watchnollywood.ml/api/";
private static ApiClient instance;
private ApiService apiService;
private ApiClient(){
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
// set your desired log level
// TODO: 21/03/2017 when going live change the log level to NONE, to enhance performance
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
// add logging as last interceptor
httpClient.addInterceptor(logging); // <-- this is the important line for logging requests!
final Gson gson = new GsonBuilder().setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES).create();
//final Retrofit retrofit = new Retrofit.Builder().baseUrl(STAGING_BASE_URL).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).addConverterFactory(GsonConverterFactory.create(gson)).client(httpClient.build()).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(STAGING_BASE_URL)
.client(httpClient.build())
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
apiService = retrofit.create(ApiService.class);
}
public static ApiClient getInstance(){
if(instance == null){
instance = new ApiClient();
}
return instance;
}
//API CALL FOR LOGIN
public Observable<UserItem> login(String email, String password){
return apiService.signIn(email,password);
}
//API CALL FOR SIGNUP
public Observable<StatusItem> signup(String email, String password, String full_name, String phone){
return apiService.signUp(email, password,phone,full_name);
}
//API CALL FOR BLOG DETAILS
public Observable<BlogResponse> blog_post(){
return apiService.blog_post();
}
}
ApiService:
public interface ApiService {
#FormUrlEncoded
#POST("signin")
Observable<UserItem> signIn(#Field("email") String email, #Field("password") String password);
#FormUrlEncoded
#POST("signup")
Observable<StatusItem> signUp(#Field("full_name")String full_name, #Field("phone") String phone, #Field("email") String email, #Field("password") String password);
#GET("blog")
Observable<BlogResponse> blog_post();
}
pojo classes:
public class BlogItem {
private int thumbNail;
private String title;
private String summary;
public int getThumbNail() {
return thumbNail;
}
public void setThumbNail(#DrawableRes int thumbNail) {
this.thumbNail = thumbNail;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getSummary() {
return summary;
}
public void setSummary(String summary) {
this.summary = summary;
}
}
public class BlogResponse {
private BlogItem[] blogItems;
public BlogItem[] getBlogItems() {
return blogItems;
}
public void setBlogItems(BlogItem[] blogItems) {
this.blogItems = blogItems;
}
}
I have a recyclerview that will hold all the information that will be coming from the server. But the problem is that when I run it I get a log response in my RUN terminal but nothing is showing on the app screen.
this is my FragmentClass that holds the information from the server:
BlogFragment:

}
public static BlogFragment newInstance(String param1) {
BlogFragment fragment = new BlogFragment();

args.putString(ARG_PARAM1, param1);
fragment.setArguments(args);
return fragment;
}
#Override

}
#Override

super.onActivityCreated(savedInstanceState);
recyclerView = (RecyclerView) view.findViewById(R.id.blog_posts_list);
setUpViews();
}
private void setUpViews() {
blogItems = new ArrayList<>();
adapter = new BlogAdapter(blogItems);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL));
BlogPost();
// populateLists();
}
private void BlogPost() {

}
}
What am I not doing right. Someone Please Help!!!

In the private void BlogPost() { method, you create BlogItems but then don't do anything with it. You probably forgot to add them to the blogItems list.
In addition, the call to adapter.notifyItemRangeChanged in that method happens way before the sequence receives data but you don't call that after each blogItem or when all blog items have arrived - the observer is on a complete different execution path than the outer BlogPost() method.
Edit spelled out:
#Override
public void onNext(BlogResponse value) {
for (BlogItem responseItem : value.getBlogItems()) {
BlogItem blogItem = new BlogItem();
blogItem.setTitle(responseItem.getTitle().toString());
blogItem.setSummary(responseItem.getSummary().toString());
blogItems.add(blogItem);
}
adapter.notifyItemRangeChanged(0, adapter.getItemCount());
}
#Override
public void onError(Throwable e) {
}
#Override
public void onComplete() {
BlogItem blogItem = new BlogItem();
blogItem.setTitle("blog_title");
blogItem.setSummary("blog_content");
blogItems.add(blogItem);
adapter.notifyItemRangeChanged(0, adapter.getItemCount());
}
