这个解决方案对我来说非常有效。

//Listener    

public abstract class InfiniteScrollListener     extendsRecyclerView.OnScrollListener {

public static String TAG = InfiniteScrollListener.class.getSimpleName();
int firstVisibleItem, visibleItemCount, totalItemCount;
private int previousTotal = 0;
private boolean loading = true;
private int visibleThreshold = 1;
private int current_page = 1;

private LinearLayoutManager mLinearLayoutManager;

public InfiniteScrollListener(LinearLayoutManager linearLayoutManager) {
    this.mLinearLayoutManager = linearLayoutManager;
}

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

    visibleItemCount = recyclerView.getChildCount();
    totalItemCount = mLinearLayoutManager.getItemCount();
    firstVisibleItem = mLinearLayoutManager.findFirstVisibleItemPosition();

    if (loading) {
        if (totalItemCount > previousTotal) {
            loading = false;
            previousTotal = totalItemCount;
        }
    }
    if (!loading && (totalItemCount - visibleItemCount - firstVisibleItem <= visibleThreshold)) {

        current_page++;

        onLoadMore(current_page);

        loading = true;
    }
}

public void resetState() {
    loading = true;
    previousTotal = 0;
    current_page = 1;
}

public abstract void onLoadMore(int current_page);
}

//Implementation into fragment 
 private InfiniteScrollListener scrollListener;

scrollListener = new InfiniteScrollListener(manager) {
        @Override
        public void onLoadMore(int current_page) {
            //Load data
        }
    };
    rv.setLayoutManager(manager);
    rv.addOnScrollListener(scrollListener);

Create an abstract class and extends RecyclerView.OnScrollListener public abstract class EndlessRecyclerOnScrollListener extends RecyclerView.OnScrollListener { private int previousTotal = 0; private boolean loading = true; private int visibleThreshold; private int firstVisibleItem, visibleItemCount, totalItemCount; private RecyclerView.LayoutManager layoutManager; public EndlessRecyclerOnScrollListener(RecyclerView.LayoutManager layoutManager, int visibleThreshold) { this.layoutManager = layoutManager; this.visibleThreshold = visibleThreshold; } @Override public void onScrolled(RecyclerView recyclerView, int dx, int dy) { super.onScrolled(recyclerView, dx, dy); visibleItemCount = recyclerView.getChildCount(); totalItemCount = layoutManager.getItemCount(); firstVisibleItem = ((LinearLayoutManager)layoutManager).findFirstVisibleItemPosition(); if (loading) { if (totalItemCount > previousTotal) { loading = false; previousTotal = totalItemCount; } } if (!loading && (totalItemCount - visibleItemCount) <= (firstVisibleItem + visibleThreshold)) { onLoadMore(); loading = true; } } public abstract void onLoadMore();} in activity (or fragment) add addOnScrollListener to recyclerView LinearLayoutManager mLayoutManager = new LinearLayoutManager(this); recyclerView.setLayoutManager(mLayoutManager); recyclerView.addOnScrollListener(new EndlessRecyclerOnScrollListener(mLayoutManager, 3) { @Override public void onLoadMore() { //TODO ... } });

试试下面:

import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.RecyclerView.LayoutManager;

/**
 * Abstract Endless ScrollListener
 * 
 */
public abstract class EndlessScrollListener extends
        RecyclerView.OnScrollListener {
    // The minimum amount of items to have below your current scroll position
    // before loading more.
    private int visibleThreshold = 10;
    // The current offset index of data you have loaded
    private int currentPage = 1;
    // True if we are still waiting for the last set of data to load.
    private boolean loading = true;
    // The total number of items in the data set after the last load
    private int previousTotal = 0;
    private int firstVisibleItem;
    private int visibleItemCount;
    private int totalItemCount;
    private LayoutManager layoutManager;

    public EndlessScrollListener(LayoutManager layoutManager) {
        validateLayoutManager(layoutManager);
        this.layoutManager = layoutManager;
    }

    public EndlessScrollListener(int visibleThreshold,
            LayoutManager layoutManager, int startPage) {
        validateLayoutManager(layoutManager);
        this.visibleThreshold = visibleThreshold;
        this.layoutManager = layoutManager;
        this.currentPage = startPage;
    }

    private void validateLayoutManager(LayoutManager layoutManager)
            throws IllegalArgumentException {
        if (null == layoutManager
                || !(layoutManager instanceof GridLayoutManager)
                || !(layoutManager instanceof LinearLayoutManager)) {
            throw new IllegalArgumentException(
                    "LayoutManager must be of type GridLayoutManager or LinearLayoutManager.");
        }
    }

    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);
        visibleItemCount = recyclerView.getChildCount();
        totalItemCount = layoutManager.getItemCount();
        if (layoutManager instanceof GridLayoutManager) {
            firstVisibleItem = ((GridLayoutManager) layoutManager)
                    .findFirstVisibleItemPosition();
        } else if (layoutManager instanceof LinearLayoutManager) {
            firstVisibleItem = ((LinearLayoutManager) layoutManager)
                    .findFirstVisibleItemPosition();
        }
        if (loading) {
            if (totalItemCount > previousTotal) {
                loading = false;
                previousTotal = totalItemCount;
            }
        }
        if (!loading
                && (totalItemCount - visibleItemCount) <= (firstVisibleItem + visibleThreshold)) {
            // End has been reached do something
            currentPage++;
            onLoadMore(currentPage);
            loading = true;
        }
    }

    // Defines the process for actually loading more data based on page
    public abstract void onLoadMore(int page);

}

感谢@Kushal，这是我实现它的方式

private boolean loading = true;
int pastVisiblesItems, visibleItemCount, totalItemCount;

mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        if (dy > 0) { //check for scroll down
            visibleItemCount = mLayoutManager.getChildCount();
            totalItemCount = mLayoutManager.getItemCount();
            pastVisiblesItems = mLayoutManager.findFirstVisibleItemPosition();

            if (loading) {
                if ((visibleItemCount + pastVisiblesItems) >= totalItemCount) {
                    loading = false;
                    Log.v("...", "Last Item Wow !");
                    // Do pagination.. i.e. fetch new data

                    loading = true;
                }
            }
        }
    }
});

别忘了加上

LinearLayoutManager mLayoutManager;
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);

大多数答案是假设RecyclerView使用LinearLayoutManager，或GridLayoutManager，甚至StaggeredGridLayoutManager，或假设滚动是垂直或水平的，但没有人张贴一个完全通用的答案。

使用ViewHolder的适配器显然不是一个好的解决方案。一个适配器可能有超过1个RecyclerView在使用它。它“改编”了它们的内容。它应该是RecyclerView(它是一个负责当前显示给用户的类，而不是适配器，它只负责向RecyclerView提供内容)，它必须通知您的系统需要更多的项(加载)。

下面是我的解决方案，只使用了RecyclerView (RecycerView. view)的抽象类。LayoutManager和RecycerView.Adapter):

/**
 * Listener to callback when the last item of the adpater is visible to the user.
 * It should then be the time to load more items.
 **/
public abstract class LastItemListener extends RecyclerView.OnScrollListener {

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

      // init
      RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();
      RecyclerView.Adapter adapter = recyclerView.getAdapter();

      if (layoutManager.getChildCount() > 0) {
        // Calculations..
        int indexOfLastItemViewVisible = layoutManager.getChildCount() -1;
        View lastItemViewVisible = layoutManager.getChildAt(indexOfLastItemViewVisible);
        int adapterPosition = layoutManager.getPosition(lastItemViewVisible);
        boolean isLastItemVisible = (adapterPosition == adapter.getItemCount() -1);

        // check
        if (isLastItemVisible)
          onLastItemVisible(); // callback
     }
   }

   /**
    * Here you should load more items because user is seeing the last item of the list.
    * Advice: you should add a bollean value to the class
    * so that the method {@link #onLastItemVisible()} will be triggered only once
    * and not every time the user touch the screen ;)
    **/
   public abstract void onLastItemVisible();

}


// --- Exemple of use ---

myRecyclerView.setOnScrollListener(new LastItemListener() {
    public void onLastItemVisible() {
         // start to load more items here.
    }
}

对于那些只想在最后一项完全显示时得到通知的人，可以使用view . canscrollvertical()。

这是我的实现:

public abstract class OnVerticalScrollListener
        extends RecyclerView.OnScrollListener {

    @Override
    public final void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        if (!recyclerView.canScrollVertically(-1)) {
            onScrolledToTop();
        } else if (!recyclerView.canScrollVertically(1)) {
            onScrolledToBottom();
        } else if (dy < 0) {
            onScrolledUp();
        } else if (dy > 0) {
            onScrolledDown();
        }
    }

    public void onScrolledUp() {}

    public void onScrolledDown() {}

    public void onScrolledToTop() {}

    public void onScrolledToBottom() {}
}

注意:如果你想支持API < 14，你可以使用recyclerView.getLayoutManager(). canscrollvertical()。
