Strange work delay TimeUnit

Question

It is necessary that immediately after clicking the text appeared, and in a second the execution would continue. In fact, everything goes wrong - the delay is triggered before the appearance of the inscription.

public void onClick(View v) { switch (v.getId()) { case 1: tvOutAns.setTextColor(colorGreen); tvOutAns.setText("правильно: " + answer); try { TimeUnit.MILLISECONDS.sleep(1000); } catch (Exception e) { } createTask(); break; } }

Accordingly, you gave the command to install a new text, it started to move the guem there, and here you are with him!
Run a cycle for him for a little longer and put a delay there?

For example, you can

 Handler handler = new Handler(); handler.postDelayed(new Runnable() { public void run() { // код, который надо запустить через секунду } }, 1000);

Or in fashionable lambdas (I recommend by the way, google retrolambda)

 (new Handler()).postDelayed(()->{/*код*/},1000);
