title: Change ImageView for a few seconds and pause UI
body: <p>Sorry, I keep on trying to adapt the tokens, but somehow I can't manage this one.</p>
  
  <p>I have the following code:</p>
  
  <pre><code>  timer.schedule(new TimerTask(){
  
       runOnUiThread(new Runnable() {
  
        public void run(){
        SplashImage.setImageDrawable(aktieknop);}
  
        });
  
    },SplashTime);
    }
  </code></pre>
  
  <p>Like this the code 'works':</p>
  
  <pre><code>  timer.schedule(new TimerTask(){
  
      // runOnUiThread(new Runnable() {
  
        public void run(){
        SplashImage.setImageDrawable(aktieknop);}
  
      //  });
  
    },SplashTime);
    }
  </code></pre>
  
  <p>Can you please help me solving this silly issue? Thanks a lot!</p>
