recyclerList.setOnScrollListener(new RecyclerView.OnScrollListener() 
            {
                @Override
                public void onScrolled(RecyclerView recyclerView, int dx,int dy)
                {
                    super.onScrolled(recyclerView, dx, dy); 
                }

                @Override
                public void onScrollStateChanged(RecyclerView recyclerView,int newState) 
                {
                    int totalItemCount = layoutManager.getItemCount();
                    int lastVisibleItem = layoutManager.findLastVisibleItemPosition();

                    if (totalItemCount> 1) 
                    {
                        if (lastVisibleItem >= totalItemCount - 1) 
                        {
                            // End has been reached
                            // do something 
                        }
                    }          
                }
            });  

有一个方法public void setOnScrollListener (RecyclerView。OnScrollListener监听器)在https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html#setOnScrollListener%28android.support.v7.widget.RecyclerView.OnScrollListener%29。使用这个

编辑:

在onScrollListener中重写onScrollStateChanged方法并执行此操作

            boolean loadMore = firstVisibleItem + visibleItemCount >= totalItemCount;

            //loading is used to see if its already loading, you have to manually manipulate this boolean variable
            if (loadMore && !loading) {
                 //end of list reached
            }

@erdna请参考我下面的代码。也许它会对你有帮助。

     int firstVisibleItem, visibleItemCount, totalItemCount;
   recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {

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

            visibleItemCount = layoutManager.getChildCount();
            totalItemCount = layoutManager.getItemCount();
            firstVisibleItem = layoutManager.findFirstVisibleItemPosition();
            Log.e("firstVisibleItem", firstVisibleItem + "");
            Log.e("visibleItemCount", visibleItemCount + "");
            Log.e("totalItemCount", totalItemCount + "");

            if (page != total_page_index) {
                if (loading) {
                    if ((visibleItemCount + firstVisibleItem) >= totalItemCount) {
                        Log.e("page", String.valueOf(page));
                        page=page+1;
                        new GetSummary().execute(String.valueOf(page), "");
                        loading = false;
                    }
                }
            }

        }


    });

正如约翰·T所建议的。只需使用下面的代码块，真的很简短，美观简单:D

public void loadMoreOnRecyclerView() {
    mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(@NonNull @NotNull RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            if (!recyclerView.canScrollVertically(1) && dy != 0) {
                //Load more items here
            }
        }
    });
}

你可以跟随我的回购来了解它的工作方式。

关于应用程序的描述信息如下:https://github.com/skydoves/Pokedex#readme

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.
    }
}
