Заполняющие спиннины с использованием модификации 1.9?

Question

Я ищу образец программы, который мог бы динамически заполнять Spinner элемент с сервера с помощью Retrofit 1.9, но все же я не мог найти ни одного образца, который может поделиться с кем-нибудь, если есть образец, касающийся этого требования, или же поделиться этим методом. Как это должно быть сделано, поскольку я новичок в битве Android, пытаясь найти решение заблаговременно!

Вот мой spinneritem класс:

public class MySpinnerItem { 

    public MySpinnerItem(){ 

    } 
    public MySpinnerItem(String text, Integer value) { 
     Text = text; 
     Value = value; 
    } 

    public String getText() { 
     return Text; 
    } 

    public void setText(String text) { 
     Text = text; 
    } 

    public Integer getValue() { 
     return Value; 
    } 

    public void setValue(Integer value) { 
     Value = value; 
    } 

    public String Text; 
    public Integer Value; 

} 

Вот мой кок адаптер:

package first.service.precision.servicefirst; 

import android.content.Context; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.TextView; 

import java.util.List; 

/** 
* Created by 4264 on 25-11-2015. 
*/ 
public class MySpinnerAdapter extends ArrayAdapter<MySpinnerItem> { 

    private Context context; 
    private List<MySpinnerItem> objects; 
    public MySpinnerAdapter(Context context, int resource, List<MySpinnerItem> objects) { 
     super(context, resource, objects); 
     this.context = context; 
     this.objects = objects; 
    } 

    @Override 
    public void add(MySpinnerItem object) { 
     this.objects.add(object); 
    } 


    @Override 
    public int getCount() { 
     return objects.size(); 
    } 

    @Override 
    public MySpinnerItem getItem(int position) { 
     return objects.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     TextView label = new TextView(context); 
     label.setText(objects.get(position).getText()); 
     return label; 
    } 

    @Override 
    public View getDropDownView(int position, View convertView, ViewGroup parent) { 
     TextView label = new TextView(context); 
     label.setText(objects.get(position).getText()); 
     return label; 
    } 
} 

Вот фрагмент, где я установить адаптер для блесен:

} 

Мои сомнения Я сделал это с использованием фиктивных данных, но мне нужно привязать ответ json от сервера к моему счетчику, o это.

Answer 1

Ниже приведен пример для установки кок

Spinner spinner = (Spinner) findViewById(R.id.spinner1); 
ArrayAdapter<String> adapter; 
List<String> data; 

data = new ArrayList<>(); 
for (int i = 0; i < 20; i++) 
     data.add("Data " + (i + 1)); 

adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data); 
spinner.setAdapter(adapter); 

Здесь данные является фиктивные данные, в вашем случае это будет фиктивные данные.

Answer 2

сначала создать theretrofitapi интерфейс

/** 
* reCreated by goodlife on 1/11/2016. 
*/ 
import java.util.List; 


import retrofit.Callback; 
import retrofit.client.Response; 
import retrofit.http.Field; 
import retrofit.http.FormUrlEncoded; 
import retrofit.http.GET; 
import retrofit.http.POST; 

/** 
* Created by Belal on 11/5/2015. 
*/ 
public interface RetrofitInternetApi { 

    //@FormUrlEncoded, we have to write this if we want to send post data to the server. 
    //@POST, because we are using an HTTP Post request we have written this. 
    // Inside it we have the URL of the script that will be receiving the post request. 
    // Note that the URL is excluding the root URL. And we have defined the root URL in our MainActivity. 
    //@Field(“key”) String variable inside key we have to write what we have written inside $_POST[‘key’] in our script. 
    // And we have to specify it for all the values we are going to send. 

    //Callback<Response> callback it is also inside the retrofit library. It will receive the output from the server. 

    //But this is only an interface and the method is abstract. 
    //We will define the method inside fetchDepartmentName() method that is declared inside MainActivity.java. 

    @GET("/getDepartmentName.php") 
    public void getDepartmentName(Callback<List<DepartmentNoRealm>> response); 

} 

затем создать функцию

private void fetchDepartmentName(){ 
//Creating a rest adapter 
     RestAdapter restAdapter = new RestAdapter.Builder() 
       .setEndpoint(ROOT_URL) 
       .build(); 

     //Creating an object of our api interface 
     RetrofitInternetApi retrofitInternetApi = restAdapter.create(RetrofitInternetApi.class); 
      //While the app fetched data we are displaying a progress dialog 
      final ProgressDialog loading = ProgressDialog.show(getActivity(), "Fetching Data", "Please wait...", false, false); 



      //Defining the method 
      retrofitInternetApi.getDepartmentName(new Callback<List<DepartmentNoRealm>>() { 
       @Override 
       public void success(List<DepartmentNoRealm> list, Response response) { 
        //Dismissing the loading progressbar 
        loading.dismiss(); 
        Log.d("JSON LIST",list.toString()); 
        //Storing the data in our list 
        departmentNoRealmList = list; 

        //Calling a method to show the list 
         showListinSpinner();   } 

       @Override 
       public void failure(RetrofitError error) { 
        //you can handle the errors here 
       } 
      }); 
     } 

затем создать класс модели

package myafya.safaricom.co.ke.myafya.model.realm; 

/** 
* Created by 001557 on 1/13/2016. 
*/ 
public class DepartmentNoRealm { 
    public int departmentID; 
    public String departmentName; 
    public String departmentURLimage; 

    public int getDepartmentID() { 
     return departmentID; 
    } 

    public void setDepartmentID(int departmentID) { 
     this.departmentID = departmentID; 
    } 

    public String getDepartmentName() { 
     return departmentName; 
    } 

    public void setDepartmentName(String departmentName) { 
     this.departmentName = departmentName; 
    } 

    public String getDepartmentURLimage() { 
     return departmentURLimage; 
    } 

    public void setDepartmentURLimage(String departmentURLimage) { 
     this.departmentURLimage = departmentURLimage; 
    } 
} 

теперь код showList в Spinner

//Our method to show list 
    private void showListinSpinner(){ 
     //String array to store all the book names 
     String[] items = new String[departmentNoRealmList.size()]; 

     //Traversing through the whole list to get all the names 
     for(int i=0; i<departmentNoRealmList.size(); i++){ 
      //Storing names to string array 
      items[i] = departmentNoRealmList.get(i).getDepartmentName(); 
     } 

     //Spinner spinner = (Spinner) findViewById(R.id.spinner1); 
     ArrayAdapter<String> adapter; 
     adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, items); 
     //setting adapter to spinner 
     spinnerDepartments.setAdapter(adapter); 
     //Creating an array adapter for list view 

    } 

Затем поделиться им и сделать ЛЕГКО

MY JSON БЫЛА

[ 
    { 
    "departmentID": "1", 
    "departmentName": "Enterprise Business Unit (EBU)", 
    "departmentURLimage": "https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcSKOZmGNAA08NbHwRJrloAouWqs6r4x7BGXY4k-ULWiHuPEobHI"
