如何VideoView以横向模式居中？我试过这个:在Manifest文件中我有:

android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"

在我的活动上我有这个代码:

RelativeLayout.LayoutParams lv= new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
                        LayoutParams.WRAP_CONTENT);
    lv.addRule(RelativeLayout.CENTER_HORIZONTAL);
    myVideoView = new VideoView(this);
    myVideoView.setLayoutParams(lv);
    myVideoView.setVideoPath(Environment
                        .getExternalStorageDirectory()
                        + "/BouyguesImages"
                        + "37" + "/" + "89Video");

    myVideoView.requestFocus();

这个VideoView我把它作为View添加到RelativeLayout:

 rr = new RelativeLayout(this);
 rr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                            LayoutParams.FILL_PARENT));
 rr.setBackgroundColor(Color.WHITE);

我的代码的结果是我的视频只在屏幕的顶部播放,在屏幕的底部是白色(relativelayout的颜色).我想在屏幕上安装VideoView,以便在屏幕底部有一小部分白色,并在屏幕顶​​部.这该怎么做？
