我正在使用CoordinatorLayout和NestedScrollView创建一个看起来像这样的活动界面:
我的布局结构如下:
当我将RecyclerView添加到布局中时,NestedScrollView会出现在AppBarLayout下面,如下图所示: 我测试了一些修复这个问题的方法,比如将NestedScrollView放入FrameLayout中或给NestedScrollView添加

当我将RecyclerView添加到布局中时,NestedScrollView会出现在AppBarLayout下面,如下图所示: 我测试了一些修复这个问题的方法,比如将NestedScrollView放入FrameLayout中或给NestedScrollView添加
android:layout_gravity="fill_vertical"
和android:fillViewport="true"
属性,但这些方法都无法解决这个问题。
