<com.scwang.smart.refresh.layout.SmartRefreshLayout
        android:id="@+id/layout_post_list_refresh"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:orientation="vertical"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@id/layout_head">

        <com.scwang.smart.refresh.header.ClassicsHeader
            android:id="@+id/refreshHead"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <androidx.viewpager2.widget.ViewPager2
            android:id="@+id/viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <com.scwang.smart.refresh.footer.ClassicsFooter
            android:id="@+id/refreshFoot"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </com.scwang.smart.refresh.layout.SmartRefreshLayout>

<androidx.constraintlayout.widget.ConstraintLayout 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">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
