如何在全高度的回收站中编写viewPager

Question

我有一个带有ViewPager的RecyclerView，而后者又有另一个recyclerView。 ViewPager中的recyclerView不会加载全部项目，而只会加载其中的一个，并且不会滚动以显示其余项目

我试图用wrap_content设置两个回收站视图的layout_height，并且也将其嵌套在nestedSCrollView内，但是没有成功。

// First outside recyclerview
<androidx.recyclerview.widget.RecyclerView        
    android:id="@+id/recyclerView"        
    android:layout_width="match_parent"        
    android:layout_height="wrap_content" />

// cell item with viewPager
<com.google.android.material.tabs.TabLayout
    android:id="@+id/tabLayout"
    android:layout_width="match_parent"
    android:layout_height="50dp" />

<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

// recyclerView inside viewPager
<androidx.recyclerview.widget.RecyclerView         
    android:id="@+id/recyclerView"        
    android:layout_width="match_parent"        
    android:layout_height="wrap_content" />

我希望外部的recyclerView可以填充整个项目的高度，而不是内部的recyclerview接缝不会加载整个项目，而是屏幕上唯一可见的没有滚动的接缝。
