在活动的onCreate（）中写下这个。

 Handler handlers = new Handler();
        handlers.postDelayed(new Runnable() {
            @Override
            public void run() {
                ImageView splash=(ImageView)findViewById(R.id.imageViewForAd)
                splash.setVisibility(View.GONE);
            }
        }, 5000);

希望它会对你有所帮助。
