Only the original thread that created a view hierarchy can touch its views的解决方案

 要想控制主线程改变view，必须得以主线程的身份。而如何让主线程知道我要改变它呢，就要用到Handler类了。。

private static Handler mHandler = new Handler(){ 
    @Override
    public void handleMessage(Message msg)
    {
        if(msg.what == 0 || msg.what == 1)
        {
            HandlerSetAdVisibility(msg.what);
        }
        else if(msg.what == 48 || msg.what == 80)
        {
            HandlerSetAdLocation(msg.what);
        }
    }
};

当需要让主线程view作出改变时，只需调用

mHandler.sendEmptyMessageDelayed(args, 0);
