RecyclerView 滚动到底部监听

据个人尝试 以下这种方案能准确监听到是否滚动到底部，可以做上拉加载更多

    protected boolean isSlideToBottom(RecyclerView recyclerView) {
        if (recyclerView == null) return false;
        if (recyclerView.computeVerticalScrollExtent() + recyclerView.computeVerticalScrollOffset() >= recyclerView.computeVerticalScrollRange())
            return true;
        return false;
    }

 recyclerview.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);
                LogUtils.d("------->isSlideToBottom:" + isSlideToBottom(recyclerView));
                if (isSlideToBottom(recyclerView)) {
                    srlLayout.setEnabled(true);
                }
            }
        });

还有一种方式调用系统的ViewCompat类：

!(ViewCompat.canScrollVertically(recyclerView, -1)  顶部是否可以滚动

!ViewCompat.canScrollVertically(recyclerView, 1)  底部是否可以滚动
