如何在同一个片段中创建多个Retrofit回调 – android

我已经为一个按钮创建了改装回调.现在我在创建另一个按钮以从另一个api获取数据时遇到了一些麻烦.

这是我的界面：

public interface APIService {

        @GET("/api/partners.json")
        Call<List<Partner>> getPartners();

        @GET("/api/drivers.json")
        Call<List<Driver>> getDrivers();

        @GET("/api/warehouses.json")
        Call<List<Warehouse>> getWarehuses();
}

这是我的api助手类：

public class APIHelper {

    public static final String BASE_URL = "https://part-of-url.herokuapp.com/";

    public static APIService apiService;

    public static APIService getApiService() {
        if (apiService == null) {
            Retrofit retrofit = new Retrofit.Builder().baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create()).build();
            apiService = retrofit.create(APIService.class);
        }
        return apiService;
    }
}

这是我的驱动程序pojo模型(所有pojo模型几乎相同)

public class Driver {

    @Expose
    private List<String> driver_name = new ArrayList<String>();

    public List<String> getDriver_name() { return driver_name; }

    public void setDriver_name(List<String> driver_name) { this.driver_name = driver_name; }
}

这是我的片段,我得到了合作伙伴的回调,需要实现另一个按钮来获取驱动程序和第三个按钮来获取一些存储空间.

public class DownloadMain extends Fragment implements Callback<Partner> {

    private static final String TAG = DownloadMain.class.getSimpleName();

    private Button dloadPartners,takeDrivers,takeWarehouses,takeUsers,takeLogs;
    private Call callPartners;

    public DownloadMain() {}

    public DownloadMain newInstance() { return new DownloadMain(); }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.download_main,container,false);

        dloadPartners = (Button) view.findViewById(R.id.downloadPartners);
        takeDrivers = (Button) view.findViewById(R.id.btnDrivers);
        dloadPartners.setonClickListener(btnListener);
        takeDrivers.setonClickListener(btnDrivers);

        callPartners = APIHelper.getApiService().getPartners();

        return view;
    }

    Button.OnClickListener btnListener = (new Button.OnClickListener() {
        @Override
        public void onClick(View v) {
            callPartners.clone().enqueue(DownloadMain.this);
            checkIfDataIsInTable();
        }
    });
 @Override
    public void onResponse(Call call,Response response) {

        if(response.body() == null) {
            try {
                response.errorBody().string();
            } catch (IOException e) {
                e.printstacktrace();
            }
            Toast.makeText(getActivity(),"No Partners!",Toast.LENGTH_SHORT).show();
        } else {
            ArrayList<String> partners = (ArrayList<String>) response.body();

            ActiveAndroid.beginTransaction();
            try {
                for (int i = 0; i < partners.size() ; i++) {
                    Partners partner = new  Partners();
                    partner.name = String.valueOf(partners);
                    partner.save();
                    Log.d("partner_ ",String.valueOf(response.body()));
                }
                ActiveAndroid.setTransactionSuccessful();
            } finally {
                ActiveAndroid.endTransaction();
            }

            Log.d(TAG,"Number of partners received: " + partners.size());
            Toast.makeText(getActivity(),"Partners downloaded!",Toast.LENGTH_SHORT).show();
        }

    }

    @Override
    public void onFailure(Call call,Throwable t) {

    }
}

现在我无法实现第二个按钮来从api获取数据.

如果有人可以帮我实现第二个按钮来从api获取驱动程序,我将不胜感激？！
