Hello try with below code:

private void setVideoSize() {

            // // Get the dimensions of the video
            int videoWidth = mediaPlayer.getVideoWidth();
            int videoHeight = mediaPlayer.getVideoHeight();
            float videoProportion = (float) videoWidth / (float) videoHeight;

            // Get the width of the screen
            int screenWidth = getWindowManager().getDefaultDisplay().getWidth();
            int screenHeight = getWindowManager().getDefaultDisplay().getHeight();
            float screenProportion = (float) screenWidth / (float) screenHeight;

            // Get the SurfaceView layout parameters
            android.view.ViewGroup.LayoutParams lp = surfaceView.getLayoutParams();
            if (videoProportion > screenProportion) {
                lp.width = screenWidth;
                lp.height = (int) ((float) screenWidth / videoProportion);
            } else {
                lp.width = (int) (videoProportion * (float) screenHeight);
                lp.height = screenHeight;
            }
            // Commit the layout parameters
            surfaceView.setLayoutParams(lp);
        }
