I need to Show Registration Form With Spinner Using Fragments and get the data using Json

This is kind of register form. At the bottom we have change language button which will reset the form and will be shown in arabic / english.

[  

   {  

      "Id":1,

      "TitleEN":"Kuwait",

      "TitleAR":"الكويت",

      "CurrencyId":1,

      "CurrencyEN":"Kuwaiti Dinar",

      "CurrencyAR":"دينار كويتى",

      "CodeEN":"KWD",

      "CodeAR":"د.ك",

      "Code":"965"

   },

   {  

      "Id":2,

      "TitleEN":"Emirates",

      "TitleAR":"الإمارات",

      "CurrencyId":2,

      "CurrencyEN":"Emirati Dirham",

      "CurrencyAR":"درهم إماراتي",

      "CodeEN":"AED",

      "CodeAR":"درهم",

      "Code":"971"

   },

   {  

      "Id":3,

      "TitleEN":"Saudi Arabia",

      "TitleAR":"السعودية",

      "CurrencyId":3,

      "CurrencyEN":"Saudi Riyal",

      "CurrencyAR":"ريال سعودى",

      "CodeEN":"SAR",

      "CodeAR":"ر.س",

      "Code":"966"

   }

]

Note.I assume you have followed the first 3 steps from this [question][1]
and will start from the following
Step 1
Add spinner in xml

 <Spinner

    android:id="@+id/spinner"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:prompt="@string/spinner_title" />

Step 2
In ApiInterface Class add the following code

@GET("/app/app.asmx/GetCountries")

Call<List<Country>> getCountry();

Step 3
Create new model class by name Country

public class Country {



@SerializedName("Id")

@Expose

private Integer id;

@SerializedName("TitleEN")

@Expose

private String titleEN;

@SerializedName("TitleAR")

@Expose

private String titleAR;

@SerializedName("CurrencyId")

@Expose

private Integer currencyId;

@SerializedName("CurrencyEN")

@Expose

private String currencyEN;

@SerializedName("CurrencyAR")

@Expose

private String currencyAR;

@SerializedName("CodeEN")

@Expose

private String codeEN;

@SerializedName("CodeAR")

@Expose

private String codeAR;

@SerializedName("Code")

@Expose

private String code;



public Integer getId() {

    return id;

}



public void setId(Integer id) {

    this.id = id;

}



public String getTitleEN() {

    return titleEN;

}



public void setTitleEN(String titleEN) {

    this.titleEN = titleEN;

}



public String getTitleAR() {

    return titleAR;

}



public void setTitleAR(String titleAR) {

    this.titleAR = titleAR;

}



public Integer getCurrencyId() {

    return currencyId;

}



public void setCurrencyId(Integer currencyId) {

    this.currencyId = currencyId;

}



public String getCurrencyEN() {

    return currencyEN;

}



public void setCurrencyEN(String currencyEN) {

    this.currencyEN = currencyEN;

}



public String getCurrencyAR() {

    return currencyAR;

}



public void setCurrencyAR(String currencyAR) {

    this.currencyAR = currencyAR;

}



public String getCodeEN() {

    return codeEN;

}



public void setCodeEN(String codeEN) {

    this.codeEN = codeEN;

}



public String getCodeAR() {

    return codeAR;

}



public void setCodeAR(String codeAR) {

    this.codeAR = codeAR;

}



public String getCode() {

    return code;

}



public void setCode(String code) {

    this.code = code;

}



}

Step 4
find view in activity or fragment and add call the request and get response and add the response in spinner adapter.Initialize a string list out side the onCreate method

List<String> codes = new ArrayList<String>();

APIInterface apiInterfacePages;

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    Spinner spinner = (Spinner) findViewById(R.id.spinner);

    apiInterfacePages= PageApiClient.getRetrofit().create(APIInterface.class);

    Call<List<Country>> getCountry = apiInterfacePages.getCountry();

    getCountry.enqueue(new Callback<List<Country>>() {

        @Override

        public void onResponse(Call<List<Country>> call, Response<List<Country>> response) {

            countryList = response.body();

            for (int i = 0; i < countryList.size(); i++) {

                codes.add(countryList.get(i).getCode());



            }

            ArrayAdapter<String> adapterTime = new ArrayAdapter<>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item, codes);

            spinner.setAdapter(adapterTime);

            spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

                @Override

                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

                    Toast.makeText(MainActivity.this, "" + countryList.get(i).getTitleEN(), Toast.LENGTH_SHORT).show();

                }



                @Override

                public void onNothingSelected(AdapterView<?> adapterView) {



                }

            });



        }



        @Override

        public void onFailure(Call<List<Country>> call, Throwable t) {



        }

    });

    }
