پخش ویدئو به صورت landscape

چطور ویدئو رو در حالت landscape به صورت full screen نمایش بدم؟

 public class ActivityVideoDetail extends Activity {

    private VideoDetail videoDetail;
    private TextView    txtResult;
    private VideoView   VideoView;


    // -------------------------
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_activity_video_detail);
        ini();
    }

    //----------------------------
    private RelativeLayout.LayoutParams paramsNotFullscreen; //if you're using RelativeLatout           


    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);

        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) //To fullscreen
        {
            paramsNotFullscreen = (RelativeLayout.LayoutParams) VideoView.getLayoutParams();
            RelativeLayout.LayoutParams params = new LayoutParams(paramsNotFullscreen);
            params.setMargins(0, 0, 0, 0);
            params.height = ViewGroup.LayoutParams.MATCH_PARENT;
            params.width = ViewGroup.LayoutParams.MATCH_PARENT;
            params.addRule(RelativeLayout.CENTER_IN_PARENT);
            VideoView.setLayoutParams(params);

        }
        else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
        {
            VideoView.setLayoutParams(paramsNotFullscreen);
        }
    }


    // -------------------------
    private void ini() {
        videoDetail = (VideoDetail) getIntent().getExtras().getSerializable(VideoDetail.VIDEO_DETAIL);
        txtResult = (TextView) findViewById(R.id.txtResult);
        txtResult.setText(videoDetail.getVideoTitle());

        Uri uri = Uri.parse(videoDetail.getVideoPath());
        //   Uri uri = Uri.parse("http://daily3gp.com/vids/747.3gp");

        VideoView videoView = (VideoView) findViewById(R.id.videoPlayer);

        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);
        mediaController.setMediaPlayer(videoView);

        videoView.setMediaController(mediaController);
        videoView.setVideoURI(uri);
        videoView.start();

    }
}

از دو فولدر layput-land , layout-port دارم استفاده میکنم

همچنان سایز کوچک نمایش می ده
