我正在设计一个复杂的ui，它有一个嵌套的ScrollView作为父级，在它里面有一个recyclerview。现在的问题是我无法滚动recyclerview中的项目。
我试过的东西
用nestedscrollview替换scrollview
有可能android:fillviewport=“正确”
禁用recyclerview的nestedscrolling

把里面的所有视图都包起来 NestedScrollView 变成一个 RelativeLayout . 对于前，

<androidx.core.widget.NestedScrollView
        android:id="@+id/studentPreviewNSV"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_marginTop="90dp"
        android:fillViewport="true"
        android:visibility="gone"
        app:layout_constraintTop_toTopOf="parent"
        tools:visibility="visible">

       <RelativeLayout
           android:layout_width="match_parent"
           android:layout_height="wrap_content">

           <androidx.constraintlayout.widget.ConstraintLayout
               android:layout_width="match_parent"
               android:layout_height="wrap_content">

                <!-- your remaining code -->

            </androidx.constraintlayout.widget.ConstraintLayout>
       </RelativeLayout>
   </androidx.core.widget.NestedScrollView>

使用 NestedScrolView 并将此添加到您的recyclerview：

recyclerView.setNestedScrollingEnabled(false);
recyclerView.setHasFixedSize(false);

或将此转换为xml：

android:nestedScrollingEnabled="false"

此外，还可以为recyclerview添加方向：

android:orientation="vertical"

我设法通过添加android:layout_marginbottom=“100dp”我想这是因为我android:layout_margintop=“90dp”到我的nestedscrollview，由于recyclerview假设所有项目都在屏幕上可见，因此不需要滚动(如果我错了，请纠正我）

<androidx.recyclerview.widget.RecyclerView
                    android:id="@+id/reportRV"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    app:layout_constraintBottom_toBottomOf="parent"
                    app:layout_constraintEnd_toEndOf="parent"
                    app:layout_constraintStart_toStartOf="parent"
                    app:layout_constraintTop_toBottomOf="@+id/courseSpinner"
                    tools:listitem="@layout/report_list_layout"
                    android:orientation="vertical"
                    android:layout_marginBottom="100dp"/>
