android - 滚动问题 - 在 NestedScrollView 中使用两个 RecyclerView

Question

我在nestedscrollview 中使用了两个recyclerview 和其他一些视图，我 android:nestedScrollingEnabled="false"在两个recyclerview 中都添加了，但滚动不流畅。

我尝试了以下方法来停止RecyclerView垂直滚动，但问题未解决

RecyclerView.LayoutManager layoutManager = new  LinearLayoutManager(getActivity()) {
        @Override
        public boolean canScrollVertically() {
            return false;
        }
    };
    recyclerView.setLayoutManager(layoutManager);

我也试过这个解决方案

ViewCompat.setNestedScrollingEnabled(recyclerView, false);

没有任何帮助，我的 recyclerview 高度都是包装内容。

在这里，我分享了我的嵌套滚动视图 xml 文件：
