在代码中添加广告到底部

ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this.findViewById(android.R.id.content)).getChildAt(0);

FrameLayout.LayoutParams params3 = new FrameLayout.LayoutParams
        (FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
//设置底部
params3.gravity = Gravity.BOTTOM;
viewGroup.addView(xplayBanner ,params3);
