这是我的xml我想在滚动时隐藏浮动动作按钮，但它们只是粘在顶部而不是隐藏我试图以不同的方式，我也看到this示例

请告诉我我做错了什么

Answer 1

您正在使用RecycleView，因此请以FloatingActionButton方式隐藏RecycleView以这种方式滚动。

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener(){
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy){
            if (dy > 0)
                fabAddNew.hide();
            else if (dy < 0)
                fabAddNew.show();
        }
    });

dy为parallel。

浮动操作按钮不会隐藏在视差效果中
