In Android\'s VideoView, is there any way to achieve the same effect as ImageView.ScaleType.CENTER_CROP?

That is, I want my VideoView to play the video such that it

    Although it is too late, but it might help someone else looking for the same problem. The following answer maintains the aspect ratio(videoProportion). The extra part of the videoview is cropped by the Phone's view.

    private void setDimension() {
         // Adjust the size of the video
         // so it fits on the screen
         float videoProportion = getVideoProportion();
         int screenWidth = getResources().getDisplayMetrics().widthPixels;
         int screenHeight = getResources().getDisplayMetrics().heightPixels;
         float screenProportion = (float) screenHeight / (float) screenWidth;
         android.view.ViewGroup.LayoutParams lp = videoView.getLayoutParams();
    
         if (videoProportion < screenProportion) {
             lp.height= screenHeight;
             lp.width = (int) ((float) screenHeight / videoProportion);
         } else {
             lp.width = screenWidth;
             lp.height = (int) ((float) screenWidth * videoProportion);
         }
         videoView.setLayoutParams(lp);
     }
    
    // This method gets the proportion of the video that you want to display.
    // I already know this ratio since my video is hardcoded, you can get the  
    // height and width of your video and appropriately generate  the proportion  
    //    as :height/width 
    private float getVideoProportion(){
      return 1.5f;
    }
