我認爲您正在尋找Splash Screen。但是你應該記住，開發者大多使用Splash屏幕來下載背景數據。不必要地使用啓動畫面可能會影響用戶體驗。 – Kunu

寫這篇文章。

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

希望它能幫助你。
