title: Short sleep till Click function
body: <p>I´ve got a quiz app where the user can answer some questions with radio buttons. Only one answer is correct. </p>
  
  <p>When I click on my button to show the right answer, it is shown in a textView. </p>
  
  <p>Until now I have another button to navigate to the next question. </p>
  
  <pre><code>b.setOnClickListener(new View.OnClickListener() {
  
              @Override
              public void onClick(View v) {
  ...
  
  }
  </code></pre>
  
  <p>Now I want to change that. When the user press the button for showing the right question, I want the app 5 seconds to sleep and then navigate to the next question.
  How can I handle that?</p>
