大家帮帮忙，admob旋转的问题，急！

[gmfy (c1vm)]

RelativeLayout.LayoutParams adParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);

    adView = new AdView(this);
    adView.setAdSize(AdSize.BANNER);
    adView.setAdUnitId(AD_UNIT_ID_HF);
    adView.setRotation(45);

    adView.loadAd(new AdRequest.Builder().build());
    adView.setBackgroundColor(Color.BLACK);
    adView.setBackgroundColor(0);

    addContentView(adView,adParams);

需要实现的效果如下图（靠右显示横幅广告90度）：
