Я хочу получить список массивов пользователей. У меня есть три класса POGO, т.е. Root(родительский класс), ContactFamilyDetails(дочерний класс), DataModelFamilyDetails (класс внуков).

Проблема, с которой я сталкивался все время, заключается в том, что при запуске приложения в то время я получаю только первое значение массива, к сожалению, я не получил остальные значения. Итак, я собираюсь поделиться всем своим кодом, поэтому, пожалуйста, просмотрите его и помогите мне в этом!! Спасибо!!

AddUserActivity (действует как MainActivity)

 public class AddUserActivity extends AppCompatActivity {

    SharedPreferences prefs;
    String FirstName;
    String ContactNo,Authentication,ID;
    FloatingActionButton FAB;
    private DataModelFamilyDetails dataModelFamDetails;
    ArrayList<DataModelFamilyDetails> dataModelFamilyDetails;
    RecyclerViewAdapter adapter;
    RecyclerView myrv;
    Context context;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_user);

       // Initialize FloatingAction button
        FAB=findViewById(R.id.fab_id);

        //SharedPreference Login details
        prefs = this.getSharedPreferences("logindata", MODE_PRIVATE);
        FirstName = prefs.getString("fname", "");
        ContactNo = prefs.getString("contact_no1", "");
        Authentication=prefs.getString("Authentication","");
        ID=prefs.getString("id","");


        //Setting RecyclerView
        myrv = findViewById(R.id.recyclerview_id);
        LinearLayoutManager mLayoutManager = new LinearLayoutManager(AddUserActivity.this);
        myrv.setLayoutManager(mLayoutManager);

        dataModelFamilyDetails=new ArrayList<DataModelFamilyDetails>();

        //Set Click listener on Floating Action Button
        FAB.setOnClickListener(new View.OnClickListener()

                }
