Android-全屏视频视图

我正在尝试使此 VideoView 以全屏模式显示：

public class ViewVideo extends Activity {
  private String filename;
  private static final int INSERT_ID = Menu.FIRST;

  @Override
  public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        System.gc();
        Intent i = getIntent();
        Bundle extras = i.getExtras();
        filename = extras.getString("videofilename");
        VideoView vv = new VideoView(getApplicationContext());
        setContentView(vv);
        vv.setVideoPath(filename);
        vv.setMediaController(new MediaController(this));
        vv.requestFocus();
        vv.start();
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      super.onCreateOptionsMenu(menu);
      menu.add(0, INSERT_ID, 0,"FullScreen");

      return true;
  }

  @Override
  public boolean onMenuItemSelected(int featureId, MenuItem item) {
      switch(item.getItemId()) {
      case INSERT_ID:
          createNote();
      }
      return true;
  }

  private void createNote() {
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,   
                             WindowManager.LayoutParams.FLAG_FULLSCREEN);  
  }
}

视频从 SD 卡播放。唯一的问题是，当我单击全屏菜单按钮时，应用程序“意外停止”。

请大家帮帮我，如何让视频全屏播放？提前致谢。

无需代码即可全屏模式播放视频

在包含视频视图的 xml 上应用以下布局格式，它肯定会以全屏模式播放视频。因为它正在运行我的:)希望有帮助

 <?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/myvideoview"
             android:layout_width="fill_parent"
             android:layout_alignParentRight="true"
             android:layout_alignParentLeft="true"
             android:layout_alignParentTop="true"
             android:layout_alignParentBottom="true"
             android:layout_height="fill_parent">
    </VideoView>
 </RelativeLayout>
