How use this lib (with Retrofit)

step1

   private RecyclerView recyclerView;
   private ProgressBar  progressbar;
   private ScrollObject object;

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

step2

private void setup{

    recyclerView = findViewById(R.id.recycler_view);
    progressbar       = findViewById(R.id.progressbar);

    object = new ScrollObject.Builder()
            .setContext(this)
            .setCurrentPage(2)
            .setVisibleThreshold(6)
            .setProgressbar(progressbar)
            .setRecyclerView(recyclerView)
            .build();

    recyclerView.addOnScrollListener(new RecyclerOnScrollListener(object) {
        @Override
        protected void onLoadMore(int currentPage, int totalPages) {
            getData(currentPage);
        }
    });
    
    ....
    recyclerView.setAdapter(...);
}

step3

 private void getData(int page) {
 
   getRetrofitApi().getData(page).enqueue(new Callback<...>() {
        @Override
        public void onResponse(Call<...> call, Response<...> response) {
            if (response.isSuccessful()){
                ...
                ...

                if (isLastPage?)
                    object.loadSuccess(false);
                else
                    object.loadSuccess(true);
            }
        }

        @Override
        public void onFailure(Call<...> call, Throwable t) {
            object.loadFailed();
        }
    });
}
