Execute function after 5 seconds in Android

You can use the Handler to add some delay.Call the method displayData() as below so that it will be executed after 5 seconds.

new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
          displayData();
        }
    }, 5000);

Note : Do not use the threads like Thread.sleep(5000); because it will block your UI and and makes it irresponsive.
