Android recyclerview中的最后一项（嵌套滚动视图内）被剪切，横向剪切viewpager

我在CoordinatorLayout中有一个滚动AppBarLayout，在第一个布局中包括另一个布局，它有嵌套的ScrollView、RecyclerView和一些其他视图

我在这个布局中面临几个问题

活动中没有平滑滚动，在它滚动的RecyclerView内部 顺利

RecyclerView中的最后一项是从底部切下的

当我改变方向时，它会在底部完全剪切ViewPager。因为我不能再滚动了

我还附上了主布局和子布局下面

活动\u detail.xml

movie\u details.xml

在movie_details.xml活动中，“viewPager”是我加载RecyclerView的地方

这是一个简单的RecyclerView，我在下面添加了适配器和RecyclerView的代码

movie\u trails\u fragment.xml

下面是RecyclerView中每个项目的布局

movie\u trail\u item.xml

下面是适配器类的代码

traileAdapter.java

公共类MovieTrailersFragment扩展片段{
公共静态最终字符串电影\u预告片\u KEY=“预告片”；
公共电影片段（）{
}
@凌驾
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
}
@凌驾
CreateView上的公共视图（布局、充气机、视图组容器、捆绑包保存状态）{
视图=充气机。充气（R.layout.movie\u trailes\u fragment，container，false）；
savedInstanceState=this.getArguments（）；
List movieTrailerList=（List）savedInstanceState.getSerializable（MOVIE\u trailes\u KEY）；
RecyclerView RecyclerView=（RecyclerView）view.findViewById（R.id.rv\u movie\u trail\u list）；
traileAdapter traileAdapter=新的traileAdapter（view.getContext（））；
LinearLayoutManager LinearLayoutManager=新的LinearLayoutManager（view.getContext（），LinearLayoutManager.VERTICAL，false）；
recyclerView.setLayoutManager（linearLayoutManager）；
recyclerView.setNestedScrollingEnabled（真）；
recyclerView.setHasFixedSize（true）；
setItemAnimator（新的DefaultItemAnimator（））；
recyclerView.setAdapter（TraileAdapter）；
TraileAdapter.准备电影预告片（电影列表）；
返回视图；
}
}

我必须将TabLayout和ViewPager分离成一个单独的线性布局，然后才能正常工作

以下是修改后的布局，以供参考：

更新

我使用的是片段，因此上面的布局显示在包含NestedScrollView的FrameLayout中，并且仅用于平板电脑大屏幕设备

在大屏幕中显示上述片段的容器：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <FrameLayout
        android:id="@+id/detail_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</android.support.v4.widget.NestedScrollView>

---

在我的案例中，当recyclerView住院时，在布局总管上的布局高度中添加0dp，以防碎片上使用时，此问题得到解决

<androidx.fragment.app.FragmentContainerView
        android:id="@+id/container"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:defaultNavHost="true"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintVertical_bias="0.0"
        app:navGraph="@navigation/navigation" />

您找到解决问题的方法了吗？我遇到了同样的问题。是的，我必须在单独的线性布局中分离出TableLayout和ViewPager，然后它才能正常工作。在RecylearView上添加一个波纹填充。然后它将显示最后一项。希望这能解决您的问题。但是NestedScrollView在哪里？你不再使用它了？我使用的是片段，所以对于平板电脑布局，我不需要NestedScrollView，只用于手机布局。
