Android VideoView crop_center

Question

I have a RelativeLayout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_gravity="center"
    android:foregroundGravity="center"
    android:gravity="center"
    android:orientation="horizontal" >

    <VideoView
        android:id="@+id/videoViewPanel"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center" 
        android:layout_centerInParent="true"/>

</RelativeLayout>

And what I need is to show video fullscreen cropped. If I could compare to ImageView, I need to show it as crop_center.

How can I make VideoView not to auto-resize video to fit center, but crop center?

In Android's VideoView, here is a simple and easy way to achieve the same effect as ImageView.ScaleType.CENTER_CROP

xml

<?xml version="1.0" encoding="utf-8"?>
<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">

    <VideoView
        android:id="@+id/videoView"
        android:layout_width="@dimen/dimen_0dp"
        android:layout_height="@dimen/dimen_0dp"
        android:visibility="gone"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

In JAVA:

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
   @Override
   public void onPrepared(MediaPlayer mp) {
         float videoRatio = mp.getVideoWidth() / (float) mp.getVideoHeight();
         float screenRatio = videoView.getWidth() / (float) 
         videoView.getHeight();
         float scaleX = videoRatio / screenRatio;
         if (scaleX >= 1f) {
             videoView.setScaleX(scaleX);
         } else {
             videoView.setScaleY(1f / scaleX);
         }
      }
});

In Kotlin:

videoView.setOnPreparedListener { mediaPlayer ->
    val videoRatio = mediaPlayer.videoWidth / mediaPlayer.videoHeight.toFloat()
    val screenRatio = videoView.width / videoView.height.toFloat()
    val scaleX = videoRatio / screenRatio
    if (scaleX >= 1f) {
        videoView.scaleX = scaleX
    } else {
        videoView.scaleY = 1f / scaleX
    }
}

And this worked for me. Hope this will help someone.
