在RecyclerView中加载更多项的一种常见方法是通过分页来实现。但是，如果想要避免使用分页，并且同时在列表末尾动态加载更多项，可以使用以下方法：

1.在RecyclerView的适配器中，添加一个监听器（OnLoadMoreListener），该监听器将在滚动到RecyclerView底部时触发加载更多项的操作。

public class MyAdapter extends RecyclerView.Adapter {

private List items;

private OnLoadMoreListener loadMoreListener;
private boolean isLoading;
private int visibleThreshold = 5;
private int lastVisibleItem, totalItemCount;

public MyAdapter(RecyclerView recyclerView, List items) {
    this.items = items;

    if (recyclerView.getLayoutManager() instanceof LinearLayoutManager) {
        final LinearLayoutManager linearLayoutManager = (LinearLayoutManager) recyclerView
                .getLayoutManager();
        recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);

                totalItemCount = linearLayoutManager.getItemCount();
                lastVisibleItem = linearLayoutManager.findLastVisibleItemPosition();
                if (!isLoading && totalItemCount <= (lastVisibleItem + visibleThreshold)) {
                    if (loadMoreListener != null) {
                        loadMoreListener.onLoadMore();
                    }
                    isLoading = true;
                }
            }
        });
    }
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    //...
}

//...

public void setLoaded() {
    isLoading = false;
}

//...

public void setOnLoadMoreListener(OnLoadMoreListener loadMoreListener) {
    this.loadMoreListener = loadMoreListener;
}

public interface OnLoadMoreListener {
    void onLoadMore();
}

}

2.实现OnLoadMoreListener接口，以便在需要加载更多项时执行操作。

myAdapter.setOnLoadMoreListener(new MyAdapter.OnLoadMoreListener() { @Override public void onLoadMore() { // 从API中获取数据，然
