如果您想要展示广告，请阅读android中的AdMob文档。 –

我认为您正在寻找Splash Screen。但是你应该记住，开发者大多使用Splash屏幕来下载背景数据。不必要地使用启动画面可能会影响用户体验。 – Kunu

写这篇文章。

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

希望它能帮助你。
