android - 在 CardView 中使用 ConstraintLayout

Question

是否可以在 CardView 中使用 ConstraintLayout 以便为 RecyclerView 膨胀它？

当前的布局是这样的，但我想在 CardView 中显示它。

引用XML代码:

<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?android:attr/listPreferredItemHeight"
    android:background="@drawable/touch_selector"
    android:paddingBottom="@dimen/list_item_padding_vertical"
    android:paddingLeft="@dimen/list_item_padding_horizontal"
    android:paddingRight="@dimen/list_item_padding_horizontal"
    android:paddingTop="@dimen/list_item_padding_vertical">

    <ImageView

        app:layout_constraintBottom_toTopOf="@+id/guideline"
        app:layout_constraintRight_toLeftOf="@+id/low_temperature"
        app:layout_constraintTop_toTopOf="@+id/guideline"
        tools:text="19\u00b0"/>

    <TextView
        android:id="@+id/low_temperature"
        android:layout_width="60dp"
        android:layout_height="wrap_content"
        android:fontFamily="sans-serif-light"
        android:gravity="end"
        android:textSize="@dimen/forecast_text_size"
        app:layout_constraintBottom_toBottomOf="@+id/guideline"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline"
        tools:text="10\u00b0"/>

    <android.support.constraint.Guideline
        android:id="@+id/guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.5"/>

</android.support.constraint.ConstraintLayout>
