To get data from spinner:

String text = spinner.getSelectedItem().toString();


To get data from Radio Button:

radiogroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
@Override
public void onCheckedChanged(RadioGroup group, int checkedId)
int option = radiogroup.getCheckedRadioButtonId();
switch (option)

case R.id.ui_professional_radiobtn:
if (professional_btn.isChecked())
String value = professional_btn.getText();
spinner.setVisibility(View.VISIBLE);


case R.id.ui_visitor_radiobtn:
if (visitor_btn.isChecked())
String value = visitor_btn.getText();
spinner.setVisibility(View.GONE);



);


Pass these values to your retrofit call.

Try this code for retrofit post api..
make pojo class for user ..

public class User


@SerializedName("firstName")
private String firstName;

@SerializedName("password")
private String password;


@SerializedName("email")
private String email;
public void setFirstName(String firstName)
this.firstName = firstName;


public String getFirstName()
return firstName;


public void setPassword(String password)
this.password = password;


public String getPassword()
return password;

public void setEmail(String email)
this.email = email;


public String getEmail()
return email;



make respone class for given by server it make pojo class..

public class ResponseData

@SerializedName("response")
private String response;

@SerializedName("details")
private String details;

public void setResponse(String response)
this.response = response;


public String getResponse()
return response;


public void setDetails(String details)
this.details = details;


public String getDetails()
return details;



after define retrofit ..

public class ApiClient
private final static String BASE_URL = "https://api.github.com"; // define your url..

public static ApiClient apiClient;
private Retrofit retrofit = null;

public static ApiClient getInstance()
if (apiClient == null)
apiClient = new ApiClient();

return apiClient;


//private static Retrofit storeRetrofit = null;

public Retrofit getClient()
return getClient(null);



private Retrofit getClient(final Context context)

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder client = new OkHttpClient.Builder();
client.readTimeout(60, TimeUnit.SECONDS);
client.writeTimeout(60, TimeUnit.SECONDS);
client.connectTimeout(60, TimeUnit.SECONDS);
client.addInterceptor(interceptor);
client.addInterceptor(new Interceptor()
@Override
public okhttp3.Response intercept(Chain chain) throws IOException
Request request = chain.request();

return chain.proceed(request);

);

retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client.build())
.addConverterFactory(GsonConverterFactory.create())
.build();


return retrofit;



make interface for api calling..

public interface ApiInterface
@POST("registrion")
Call<ResponseData> userReg(@Body User user);


api calling into activity or fragmen..

ApiInterface apiInterface = ApiClient.getInstance().getClient().create(ApiInterface.class);
User user=new User();
user.setEmail("abcd@gmail.com");
user.setPassword("123");
user.setFirstName("Vikas");
Call<ResponseData> dataCall=apiInterface.userReg(user);
dataCall.enqueue(new Callback<ResponseData>()
@Override
public void onResponse(Call<ResponseData> call, Response<ResponseData> response)
if (response!=null && response.isSuccessful() && response.body()!=null)
// show message



@Override
public void onFailure(Call<ResponseData> call, Throwable t)
Log.d("Error",t.getMessage());

);


add below dependecy into app level gradle file..

implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'
