这里我的解决方案使用AsyncListUtil，在网络上说: 注意，这个类使用一个线程来加载数据，所以它适合从二级存储(如磁盘)加载数据，但不适合从网络加载数据。 但是我使用odata来读取数据并工作良好。 我在示例中遗漏了数据实体和网络方法。 我只包括示例适配器。

public class AsyncPlatoAdapter extends RecyclerView.Adapter {

    private final AsyncPlatoListUtil mAsyncListUtil;
    private final MainActivity mActivity;
    private final RecyclerView mRecyclerView;
    private final String mFilter;
    private final String mOrderby;
    private final String mExpand;

    public AsyncPlatoAdapter(String filter, String orderby, String expand, RecyclerView recyclerView, MainActivity activity) {
        mFilter = filter;
        mOrderby = orderby;
        mExpand = expand;
        mRecyclerView = recyclerView;
        mActivity = activity;
        mAsyncListUtil = new AsyncPlatoListUtil();

    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).
                inflate(R.layout.plato_cardview, parent, false);

        // Create a ViewHolder to find and hold these view references, and
        // register OnClick with the view holder:
        return new PlatoViewHolderAsync(itemView, this);
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        final Plato item = mAsyncListUtil.getItem(position);
        PlatoViewHolderAsync vh = (PlatoViewHolderAsync) holder;
        if (item != null) {
            Integer imagen_id = item.Imagen_Id.get();
            vh.getBinding().setVariable(BR.plato, item);
            vh.getBinding().executePendingBindings();
            vh.getImage().setVisibility(View.VISIBLE);
            vh.getProgress().setVisibility(View.GONE);
            String cacheName = null;
            String urlString = null;
            if (imagen_id != null) {
                cacheName = String.format("imagenes/imagen/%d", imagen_id);
                urlString = String.format("%s/menusapi/%s", MainActivity.ROOTPATH, cacheName);
            }
            ImageHelper.downloadBitmap(mActivity, vh.getImage(), vh.getProgress(), urlString, cacheName, position);
        } else {
            vh.getBinding().setVariable(BR.plato, item);
            vh.getBinding().executePendingBindings();
            //show progress while loading.
            vh.getImage().setVisibility(View.GONE);
            vh.getProgress().setVisibility(View.VISIBLE);
        }
    }

    @Override
    public int getItemCount() {
        return mAsyncListUtil.getItemCount();
    }

    public class AsyncPlatoListUtil extends AsyncListUtil<Plato> {
        /**
         * Creates an AsyncListUtil.
         */
        public AsyncPlatoListUtil() {
            super(Plato.class, //my data class
                    10, //page size
                    new DataCallback<Plato>() {
                        @Override
                        public int refreshData() {
                            //get count calling ../$count ... odata endpoint
                            return countPlatos(mFilter, mOrderby, mExpand, mActivity);
                        }

                        @Override
                        public void fillData(Plato[] data, int startPosition, int itemCount) {
                            //get items from odata endpoint using $skip and $top
                            Platos p = loadPlatos(mFilter, mOrderby, mExpand, startPosition, itemCount, mActivity);
                            for (int i = 0; i < Math.min(itemCount, p.value.size()); i++) {
                                data[i] = p.value.get(i);
                            }

                        }
                    }, new ViewCallback() {
                        @Override
                        public void getItemRangeInto(int[] outRange) {
                            //i use LinearLayoutManager in the RecyclerView
                            LinearLayoutManager layoutManager = (LinearLayoutManager) mRecyclerView.getLayoutManager();
                            outRange[0] = layoutManager.findFirstVisibleItemPosition();
                            outRange[1] = layoutManager.findLastVisibleItemPosition();
                        }

                        @Override
                        public void onDataRefresh() {
                            mRecyclerView.getAdapter().notifyDataSetChanged();
                        }

                        @Override
                        public void onItemLoaded(int position) {
                            mRecyclerView.getAdapter().notifyItemChanged(position);
                        }
                    });
            mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
                @Override
                public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                    onRangeChanged();
                }
            });
        }
    }
}

检查的每一件事都有详细的解释: 使用RecyclerView从A到Z分页

    mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrollStateChanged(RecyclerView recyclerView,
                                     int newState) {
        super.onScrollStateChanged(recyclerView, newState);
    }

    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);
        int visibleItemCount = mLayoutManager.getChildCount();
        int totalItemCount = mLayoutManager.getItemCount();
        int firstVisibleItemPosition = mLayoutManager.findFirstVisibleItemPosition();

        if (!mIsLoading && !mIsLastPage) {
            if ((visibleItemCount + firstVisibleItemPosition) >= totalItemCount
                    && firstVisibleItemPosition >= 0) {
                loadMoreItems();
            }
        }
    }
})

loadMoreItems ():

private void loadMoreItems() {
    mAdapter.removeLoading();
    //load data here from the server

    // in case of success
    mAdapter.addData(data);
    // if there might be more data
    mAdapter.addLoading();
}

在MyAdapter中:

private boolean mIsLoadingFooterAdded = false;

public void addLoading() {
    if (!mIsLoadingFooterAdded) {
        mIsLoadingFooterAdded = true;
        mLineItemList.add(new LineItem());
        notifyItemInserted(mLineItemList.size() - 1);
    }
}

public void removeLoading() {
    if (mIsLoadingFooterAdded) {
        mIsLoadingFooterAdded = false;
        int position = mLineItemList.size() - 1;
        LineItem item = mLineItemList.get(position);

        if (item != null) {
            mLineItemList.remove(position);
            notifyItemRemoved(position);
        }
    }
}

public void addData(List<YourDataClass> data) {

    for (int i = 0; i < data.size(); i++) {
        YourDataClass yourDataObject = data.get(i);
        mLineItemList.add(new LineItem(yourDataObject));
        notifyItemInserted(mLineItemList.size() - 1);
    }
}

这是另一种方法。它将与任何布局管理器工作。

使Adapter类抽象 然后在适配器类中创建一个抽象方法。load ()) 在onBindViewHolder中检查位置，如果最后调用load() 在活动或片段中创建适配器对象时重写load()函数。 在重载加载函数实现你的loadmore调用

为了详细了解，我写了一篇博客文章和示例项目 http://sab99r.com/blog/recyclerview-endless-load-more/

MyAdapter.java

public abstract class MyAdapter extends RecyclerView.Adapter<ViewHolder>{

        @Override
        public void onBindViewHolder(ViewHolder holder, int position) {
            //check for last item
            if ((position >= getItemCount() - 1))
                load();
        }

        public abstract void load();
}

MyActivity.java

public class MainActivity extends AppCompatActivity {
    List<Items> items;
    MyAdapter adapter;

   @Override
    protected void onCreate(Bundle savedInstanceState) {
    ...
    adapter=new MyAdapter(items){
            @Override
            public void load() {
                //implement your load more here
                Item lastItem=items.get(items.size()-1);
                loadMore();
            }
        };
   }
}

我检测加载事件的方法不是检测滚动，而是监听最后一个视图是否附加。如果附加了最后一个视图，我认为这是加载更多内容的时机。

class MyListener implements RecyclerView.OnChildAttachStateChangeListener {
    RecyclerView mRecyclerView;

    MyListener(RecyclerView view) {
        mRecyclerView = view;
    }

    @Override
    public void onChildViewAttachedToWindow(View view) {

    RecyclerView.Adapter adapter = mRecyclerView.getAdapter();
    RecyclerView.LayoutManager mgr = mRecyclerView.getLayoutManager();
    int adapterPosition = mgr.getPosition(view);

    if (adapterPosition == adapter.getItemCount() - 1) {
        // last view was attached
        loadMoreContent();
    }

    @Override
    public void onChildViewDetachedFromWindow(View view) {}
}

我让你接近我。对我来说没问题。

我希望这对你有所帮助。

/**

public abstract class BaseScrollListener extends RecyclerView.OnScrollListener {

    protected RecyclerView.LayoutManager layoutManager;

    public BaseScrollListener(RecyclerView.LayoutManager layoutManager) {

        this.layoutManager = layoutManager;

        this.init();
    }

    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

        super.onScrolled(recyclerView, dx, dy);

        this.onScroll(recyclerView, this.getFirstVisibleItem(), this.layoutManager.getChildCount(), this.layoutManager.getItemCount(), dx, dy);
    }

    private int getFirstVisibleItem(){

        if(this.layoutManager instanceof LinearLayoutManager){

            return ((LinearLayoutManager) this.layoutManager).findFirstVisibleItemPosition();
        } else if (this.layoutManager instanceof StaggeredGridLayoutManager){

            int[] spanPositions = null; //Should be null -> StaggeredGridLayoutManager.findFirstVisibleItemPositions makes the work.

            try{

                return ((StaggeredGridLayoutManager) this.layoutManager).findFirstVisibleItemPositions(spanPositions)[0];
            }catch (Exception ex){

                // Do stuff...
            }
        }

        return 0;
    }

    public abstract void init();

    protected abstract void onScroll(RecyclerView recyclerView, int firstVisibleItem, int visibleItemCount, int totalItemCount, int dx, int dy);

}

下面是一个简单实现无尽滚动RecyclerView的例子，使用一个从各种来源编译的简单库。

在build.gradle中添加这一行

implementation 'com.hereshem.lib:awesomelib:2.0.1'

在活动中创建RecyclerView布局

<com.hereshem.lib.recycler.MyRecyclerView
        android:id="@+id/recycler"
        app:layoutManager="LinearLayoutManager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

通过传递ViewHolder支持的类来创建一个ViewHolder

public static class EVHolder extends MyViewHolder<Events> {
    TextView date, title, summary;
    public EVHolder(View v) {
        super(v);
        date = v.findViewById(R.id.date);
        title = v.findViewById(R.id.title);
        summary = v.findViewById(R.id.summary);
    }
    @Override
    public void bindView(Events c) {
        date.setText(c.date);
        title.setText(c.title);
        summary.setText(c.summary);
    }
}

通过在适配器中传递项目、类和布局来创建项目列表变量和很少行的适配器

List<Events> items = new ArrayList<>();
MyRecyclerView recycler = findViewById(R.id.recycler);
RecyclerViewAdapter adapter = new RecyclerViewAdapter(this, items, EVHolder.class, R.layout.row_event);
recycler.setAdapter(adapter);

ClickListener和LoadMore Listener可以通过以下几行添加

recycler.setOnItemClickListener(new MyRecyclerView.OnItemClickListener() {
    @Override
    public void onItemClick(int position) {
        Toast.makeText(MainActivity.this, "Recycler Item Clicked " + position, Toast.LENGTH_SHORT).show();
    }
});

recycler.setOnLoadMoreListener(new MyRecyclerView.OnLoadMoreListener() {
    @Override
    public void onLoadMore() {
        loadData();
    }
});
loadData();

数据加载后必须调用此函数

recycler.loadComplete();

当不需要LoadMore时，可以通过调用LoadMore来隐藏布局

recycler.hideLoadMore();

更多的例子可以在这里找到

希望这对你有所帮助。
