Answer 1

要从微调框获取数据：

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

要从单选按钮获取数据，请执行以下操作：

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);
                    }
            }
        }
    });

将这些值传递给您的改造电话。

请尝试使用此代码来改装api。为用户创建pojo类。

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;
}

}

使服务器提供给它的respone类成为make pojo类。

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;
}

}

在定义改造后..

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;
}

}

用于api调用的make接口。

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

}

api调用活动或香料。

    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());
        }
    });

将以下依赖项添加到应用程序级别的gradle文件中。

   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'
