Question

this is my code:

  setContentView(R.layout.activity_video);
        SimpleExoPlayerView exoPlayerView;
        //SimpleExoPlayer exoPlayer;
        Intent intent = getIntent();

        String url_video_passato = intent.getStringExtra("URL_VIDEO");
        System.out.println("PASSATO?"+url_video_passato);
       // String videoURL = "http://vod06.msf.ticdn.it/farmunica/2017/11/124899_15fc565cd8f965/15fc565cd8f965-11_0.mp4";

Try change the resize mode of SimpleExoPlayerView like below

app:resize_mode="fill"

You may also set it from java

simpleExoPlayerView.setResizeMode(AspectRatioFrameLayout.RESIZE_MODE_FILL);
