你好朋友我想在我的recycleview中集成分页所以下面是我的代码

在 onCreateVIew 中

  LinearLayoutManager  mLayoutManager = new LinearLayoutManager(getActivity());
    mRecyclerView = (RecyclerView) rootView.findViewById(R.id.task_recycle);
    mRecyclerView.setHasFixedSize(true);
    mRecyclerView.setLayoutManager(mLayoutManager);
 mRecyclerView.setOnScrollListener(new EndlessRecyclerOnScrollListener(mLayoutManager) {
            @Override
            public void onLoadMore(int current_page) {
                if (OnzupApplication.mPendingDatas.size() < total) {
                    page++;
                    new getPendingTask(false,true).execute();

                }
            }

        });

if (mAllMethods.check_Internet() == true) {
        new getPendingTask(true,false).execute();
    } else {
        mAllMethods.ShowDialog(getActivity(), "", getString(R.string.net_not_available), "OK");
    }

调用 AsyncTask

    public class getPendingTask extends AsyncTask<Void, Void, Void> {

    private boolean showLoading;
    boolean pagination;

    public getPendingTask(boolean showLoading,boolean page) {
        this.showLoading = showLoading;
        this.pagination=page;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        if (showLoading == true) {
            mProgressDialog = ProgressDialog.show(getActivity(), "", getString(R.string.loading));

        }
    }

    @Override
    protected Void doInBackground(Void... voids) {
        mGetPendigTask = (GetAllPendigTask) mPostParseGet.getPendingTask(mGetPendigTask, token, page);
        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        super.onPostExecute(aVoid);
        if (showLoading == true) {
            if (mProgressDialog != null) {
                mProgressDialog.dismiss();
            }
        }

        try {
            if (mPostParseGet.isNetError) {
                mAllMethods.ShowNoConnectionDialog(mActivity, mContext, "", getString(R.string.net_not_available), getString(R.string.setting), getString(R.string.cancel));
            } else if (mPostParseGet.isOtherError) {
                if (!mPostParseGet.isRequestTimeOutError) {
                    new ActivityHelper(mActivity).sendMail(token);
                }
                mAllMethods.ShowDialog(mActivity, "", getString(R.string.data_not_found), "OK");
            } else {
                if (mGetPendigTask.isSuccess() == true) {
                    mPendingDatas = getData();


                    total = Integer.parseInt(mGetPendigTask.getTotalitems());

                    if (mGetPendigTask.getTasks().size() > 0) {
                        mTextViewNoData.setVisibility(View.GONE);
                        mRecyclerView.setVisibility(View.VISIBLE);
                        mAllPendingRecyclerAdapter = new AllPendingRecyclerAdapter(getActivity(), OnzupApplication.mPendingDatas);
                        if (pagination==false)
                        {
                            mRecyclerView.setAdapter(mAllPendingRecyclerAdapter);
                        }
                        mAllPendingRecyclerAdapter.notifyDataSetChanged();
                    } else {
                        mTextViewNoData.setVisibility(View.VISIBLE);
                        mRecyclerView.setVisibility(View.GONE);
                    }

                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

当我调用上面的代码时，加载了 1 页，但是当我滚动第二页数据时没有加载任何想法我该如何解决这个问题？

【解决方案1】：

因为这条线

 mAllPendingRecyclerAdapter = new AllPendingRecyclerAdapter(getActivity(), OnzupApplication.mPendingDatas);

当您在 recyclerview 中使用加载更多功能时，您确实创建了适配器。您应该在自己的适配器中添加数据，而不是创建新的
