如何通过API URL索引使用Recyclerview实现分页

问题描述

我知道标题看起来很奇怪，但是基本上我想要的是将分页应用于列表，并使用url api端点作为参数来控制它！!

I know the title seems weird, but basically what I want is to apply pagination to my list and control it using the url api endpoint as a parameter.!

因此端点看起来像这样，例如> www.someapi.com/josn/list?pageIndex=1

so the endpoint looks like this for example > www.someapi.com/josn/list?pageIndex=1

它将给出一个包含10个项目的数组的响应，如果我想要更多，我必须将参数的索引更改为2，依此类推.！

and it will give a response with array of 10 items, and if I want more I have to change the index of the parameter to 2 and so on.!

响应

{
    "Succeeded": true,
    "AvailableChallenge": true,
    "DebugError": "",
    "NextPage": 2,
    "AllPages": 2,
    "Challenges": [
        {
            "ID": 114,
            "Title": "Amet sit id ratione dolorem numquam"
        },
        {
            "ID": 114,
            "Title": "Amet sit id ratione dolorem numquam"
        }
        ...
        ..
        .
        ]
 }

我捆绑了所有内容，但无法正确完成，我已经尝试了 ，没有任何运气.我还尝试使用这两个库 分页 & recyclerview-paginated 甚至是这个 SuperRecyclerView .但这没用.！

I tied everything, but couldn't get it done correctly, I have tried most of the solutions in here and no luck.I've also tried to use these two library Paginate & recyclerview-paginated and even this SuperRecyclerView. but it didn't work.!

任何具有最佳控制逻辑的帮助都将大有帮助.

Any help with the best logic for controlling this will help a lot.

SuperRecyclerView

Code for SuperRecyclerView

public class ChallengesListFragment extends BaseFragment {

  private int pageNumber = 1;
  private SuperRecyclerView recyclerview;
  private ArrayList<ChallengeActive> data;
  private ChallengesAdapter adapter;

public View onCreateView(LayoutInflater inflater, ViewGroup container,
      Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_challenges_list, container, false);
    initView(rootView);
    initRecycler();
    getData(1);
    return rootView;
  }

 private void initRecycler() {
    data = new ArrayList<>();

    final RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity());
    recyclerview.setLayoutManager(mLayoutManager);
    adapter = new ChallengesAdapter(data, getActivity(), this);
    recyclerview.setAdapter(adapter);

    recyclerview.setupMoreListener(new OnMoreListener() {
      @Override
      public void onMoreAsked(int overallItemsCount, int itemsBeforeMore, int maxLastVisiblePosition) {

        pageNumber++;
        getData(maxLastVisiblePosition);
      }
    }, 10);

    recyclerview.setRefreshListener(new OnRefreshListener() {
      @Override
      public void onRefresh() {
        pageNumber = 1;
        getData(pageNumber);
      }
    });

  }

  private void getData(final int pageNumber) {

      WebRequests.GetActiveChallenges(pageNumber, new onResult() {
      @Override
      public void onSuccess(Object object) {
        ArrayList<ChallengeActive> list = (ArrayList<ChallengeActive>) object;
        data.clear();
        data.addAll(list);
        adapter.notifyDataSetChanged();
      }

      @Override
      public void onFail(Object object) {
        Toast.makeText(getActivity(), "Something went wrong, try again later",
            Toast.LENGTH_SHORT).show();
      }
    });
  }
}

一段时间后，我使用 分页库

After some time, I did it using Paginate Library

代码

public class ChallengesListFragment extends BaseFragment implements OnRefreshListener, Paginate.Callbacks {

// other variables..
  private int currentPage = 1;
  private boolean hasMore;
  private boolean loadingInProgress;


  @RequiresApi(api = VERSION_CODES.LOLLIPOP)
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
      Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_challenges_list, container, false);
    initView(rootView);
    initToolbar();
    initRecycler();
    getData();

    return rootView;
  }

  private void initRecycler() {
    data = new ArrayList<>();
    mLayoutManager = new LinearLayoutManager(getActivity());
    recyclerview.setLayoutManager(mLayoutManager);
    adapter = new ChallengesAdapter(data, getActivity(), this);
    recyclerview.setAdapter(adapter);

    Paginate.with(recyclerview, this)
        .setLoadingTriggerThreshold(3)
        .addLoadingListItem(false)
        .build();
  }

  private void getData() {

     swipeRefresh.setRefreshing(true);
    WebRequests.GetActiveChallenges(currentPage, new onResult() {
      @Override
      public void onSuccess(Object object) {

        ArrayList<Challenge> list = (ArrayList<Challenge>) object;
        data.addAll(list);
        adapter.notifyDataSetChanged();

        if (list.size() == 10) {
          currentPage++;
          hasMore = true;
        } else {
          hasMore = false;
        }
        loadingInProgress = false;
        swipeRefresh.setRefreshing(false);


      }

      @Override
      public void onFail(Object object) {
        Toast.makeText(getActivity(), "Something went wrong, try again later",
            Toast.LENGTH_SHORT).show();
        swipeRefresh.setRefreshing(false);

      }
    });

  }

  public ChallengesListFragment() {
   }

  @Override
  public void onRefresh() {
    currentPage = 1;
    loadingInProgress = true;
    getData();
   }

  @Override
  public void onLoadMore() {
    loadingInProgress = true;
     Handler mHandler = new Handler();
    final Runnable hintRunnable = new Runnable() {
      @Override
      public void run() {
        getData();
      }
    };
    mHandler.postDelayed(hintRunnable, 1500);

  }

  @Override
  public boolean isLoading() {
    return loadingInProgress;
  }

  @Override
  public boolean hasLoadedAllItems() {
    return !hasMore;
  }

}
