Android 在特定位置将水平回收视图转换为垂直回收视图

我想将水平回收视图插入/显示到特定位置（在此示例位置：1）

垂直循环视图-显示文本视图+形状（rectange） 水平循环视图-显示图像视图（彼此相邻）

.XML的

horizontal_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.RecyclerView
    android:id="@+id/horizontal_recyclerview"
    android:layout_width="368dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="60dp"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginTop="2dp"
    android:padding="0dp"/>

<android.support.v7.widget.RecyclerView
    android:id="@+id/vertical_recyclerview"
    android:layout_width="368dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="60dp"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginTop="2dp"
    android:padding="0dp"/>

</android.support.constraint.ConstraintLayout>

垂直适应级

我是安卓新手，所以我希望人们能对什么是错误以及如何修复给出一些好的解释。每一个建议都会被欣然接受。如果有人真的对此进行调查并加以解释，我将不胜感激，因为我现在感觉很失落

我理解我丢失的部分-onCreateView方法返回需要某种布局类型的特定视图。例如，hor_布局-仅容纳RecycleView。hor_布局_项-仅保存图像视图。据我所知，我只能将一个布局传递给ViewHolder，因此，例如，如果我传递hor_布局，我将可以访问RV，但不能访问ImageView。显然，可以将两个元素放在一个布局中，但这会产生不必要的空间（ImageView下的RV），可能还有其他更简单的解决方案。有什么想法吗？谢谢。我理解我丢失的部分-onCreateView方法返回需要某种布局类型的特定视图。例如，hor_布局-仅容纳RecycleView。hor_布局_项-仅保存图像视图。据我所知，我只能将一个布局传递给ViewHolder，因此，例如，如果我传递hor_布局，我将可以访问RV，但不能访问ImageView。显然，可以将两个元素放在一个布局中，但这会产生不必要的空间（ImageView下的RV），可能还有其他更简单的解决方案。有什么想法吗？谢谢
