Kotlin

private lateinit var runnable: Runnable
override fun onCreate(savedInstanceState: Bundle?) {
    val handler = Handler()
    runnable = Runnable {

        handler.postDelayed(runnable, 2000)
    }
    handler.postDelayed(runnable, 2000)
}

Java

Runnable runnable;
Handler handler;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    handler = new Handler();
    runnable = new Runnable() {
        @Override
        public void run() {
            // do your work
            handler.postDelayed(this, 1000);
        }
    };
    handler.postDelayed(runnable, 1000);
}
