Video view is not full screen in landscape mode

I am using a video view designed with xml. This video is full screen in Portrait mode but when it turns to the landscape mode, it is left aligned and both width and height are wrapped instead of full screen.

I referred these, but still no solution for this.

Fullscreen VideoView isn't Centered

Android-Video View in Fullscreen

Any one knows the answer for this?

Update: Here is my xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">


<VideoView android:id="@+id/youtubewebView"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:layout_alignParentLeft="true" android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentBottom="true" android:layout_gravity="fill" />

</RelativeLayout>

Update 2:

public class VideoStreamingActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    final VideoView videoView = (VideoView)findViewById(R.id.your_video_view);
    String videoUrl = "http://www.pocketjourney.com/downloads/pj/video/famous.3gp";
    try {
    Uri uri = Uri.parse(videoUrl);
    videoView.setVideoURI(uri);
    videoView.setMediaController(new MediaController(this));
    videoView.requestFocus();
    //videoView.start();
    videoView.setOnErrorListener(new OnErrorListener() {

        @Override
        public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
            Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show();
            return true;
        }
    });

    }catch (Exception e) {
        e.printStackTrace();
    }

    videoView.setOnPreparedListener(new OnPreparedListener() {

        public void onPrepared(MediaPlayer mp) {
            videoView.start();
        }
    });

}

@Override
protected void onPause() {
    Toast.makeText(getApplicationContext(), "pause", Toast.LENGTH_SHORT).show();
    super.onPause();
}

@Override
protected void onRestart() {
    Toast.makeText(getApplicationContext(), "restart", Toast.LENGTH_SHORT).show();
    super.onRestart();
}

@Override
protected void onResume() {
    Toast.makeText(getApplicationContext(), "resume", Toast.LENGTH_SHORT).show();
    super.onResume();
}

}

Are you sure that it is not filling up the screen. it works fine for me. Here is the xml file,

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <VideoView android:id="@+id/video"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
       android:layout_alignParentRight="true"
       android:layout_alignParentBottom="true"
       android:layout_alignParentTop="true"
        />
</RelativeLayout>

onCreate()

VideoView video=null;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    video=(VideoView)findViewById(R.id.video);
    video.setVideoURI(Uri.parse("http://www.pocketjourney.com/downloads/pj/video/famous.3gp"));
    video.start();
}
