How to get data from multiple API Retrofit 2?-CodePudding

I created an app where data is loaded from server with the help of an API using Retrofit 2 . How can I fetch data from different API with the help of single API interface method?

If I request data from first URL then i should get data from first API, And if i request data from second URL then i should get data from second URL only. how can i do this with the help of a single API interface class.

This is my Retrofit

public class RetrofitInstance {
static {
    System.loadLibrary("keys");
}
public static native String getUrl();


private static Retrofit retrofit;
public static Retrofit getRetrofit() {
    if (retrofit == null) {
        retrofit = new Retrofit.Builder().baseUrl(getUrl()).addConverterFactory(GsonConverterFactory.create()).build();
    }
    return retrofit;
}

}

and This is my API interface class where my api url is stored.

public interface APIInterfaces {

@GET("first.php")
Call<List<VideoModels>> getFirstVid();

@GET("second.php")
Call<List<VideoModels>> getSecondVid();


@GET("third.php")
Call<List<VideoModels>> getThirdVid();


@GET("fourth.php")
Call<List<VideoModels>> getFourthVid();

@GET("fifth.php")
Call<List<VideoModels>> getFifthVid();
}

This is my Activity and API interface method. Where I have to show details from API.

public class TestFragment extends Fragment {
TestFragmentBinding binding;

ArrayList<VideoModels> list = new ArrayList<>();
APIInterfaces interfaces;
@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    
    binding = TestFragmentBinding.inflate(inflater, container, false);

    ThumbnailViewer adapter = new ThumbnailViewer(list,getContext());
    binding.mRecyclerView.setAdapter(adapter);
    
    GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(),2);
    binding.mRecyclerView.setLayoutManager(gridLayoutManager);

    //Setup Data from API to ArrayList.

    interfaces = RetrofitInstance.getRetrofit().create(APIInterfaces.class);

    // I want to Change url as request and show data from "getSecondVid()","getThirdVid()" with singple interface method. Is it possible? 
    interfaces.getFirstVid().enqueue(new Callback<List<VideoModels>>() {
        @SuppressLint("NotifyDataSetChanged")
        @Override
        public void onResponse(Call<List<VideoModels>> call, Response<List<VideoModels>> response) {
            list.clear();
            if (response.isSuccessful() && response !=null) {
                list.addAll(response.body());
                adapter.notifyDataSetChanged();
            }
            else {
                Toast.makeText(getContext(), "No Data Found", Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<List<VideoModels>> call, Throwable t) {
            Toast.makeText(getContext(), "Unable to Connect", Toast.LENGTH_SHORT).show();
        }
    });


    return binding.getRoot();
}

}

Your answer is very helpful for me.

CodePudding user response：

You can do something like this

public interface APIInterfaces {
    @GET
    Call<List<VideoModels>> getVid(@Url String URL);
}

For every call, you just have to pass the URL to the same method.

you implementation will change to this

// you can pass the URL for the first.php, second.php video etc.
    interfaces.getVid("your_url").enqueue(new Callback<List<VideoModels>>() {
            @SuppressLint("NotifyDataSetChanged")
            @Override
            public void onResponse(Call<List<VideoModels>> call, Response<List<VideoModels>> response) {
                list.clear();
                if (response.isSuccessful() && response !=null) {
                    list.addAll(response.body());
                    adapter.notifyDataSetChanged();
                }
                else {
                    Toast.makeText(getContext(), "No Data Found", Toast.LENGTH_SHORT).show();
                }
            }
    
            @Override
            public void onFailure(Call<List<VideoModels>> call, Throwable t) {
                Toast.makeText(getContext(), "Unable to Connect", Toast.LENGTH_SHORT).show();
            }
        });
