Expand card view height to height of contained exoplayer, crop only left and right sides of expoplayer

Question

I have an ex0player in a RecyclerView of CardViews. The height of the exoplayer needs to be changed programmatically based on the height of the video contained. This height value is passed returned from the API call in pixels. Here is the layout of the ViewHolder:

<androidx.cardview.widget.CardView 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"
    app:cardCornerRadius="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">


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


        <com.google.android.exoplayer2.ui.PlayerView
            android:id="@+id/toroPlayerView"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:background="@color/transparent"
            android:visibility="invisible"
            app:controller_layout_id="@layout/v_player_controls"
            app:keep_content_on_player_reset="true"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="@+id/communityPlayableIv"
            app:player_layout_id="@layout/toro_exo_player_view"
            app:resize_mode="zoom"
            app:show_buffering="when_playing"
            app:shutter_background_color="@android:color/transparent"
            app:surface_type="texture_view"
            app:use_controller="false" />

        <androidx.appcompat.widget.AppCompatImageView
            android:id="@+id/communityPlayableIv"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:adjustViewBounds="true"
            android:background="@color/black"
            android:scaleType="centerCrop"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            tools:layout_editor_absoluteY="0dp"
            tools:src="@color/alpha_grey" />

        <androidx.appcompat.widget.AppCompatImageView
            android:id="@+id/volumeIv"
            android:layout_width="64dp"
            android:layout_height="64dp"
            android:layout_gravity="bottom|end"
            android:padding="15dp"
            android:src="@drawable/ic_volume_off"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent" />


    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.cardview.widget.CardView>

Here is how I am adjusting the height and aspect ratio:

   if (model.mediaHeight != 0 && model.mediaHeight != null ) {
            communityPlayableCl.requestLayout()
            communityPlayableCl.layoutParams.height = model.mediaHeight

        }



    val constraintSet = ConstraintSet()
    constraintSet.clone(communityPlayableCl)
    constraintSet.setDimensionRatio(itemView.id,model.mediaAspectRatio)
    constraintSet.applyTo(communityPlayableCl)

This crops the top and bottom of a 640x640 video

Answer 1

I ended up setting the dimensions of the view manually using the passed aspect ratio
