title: Animating LinearLayout background to blink in Android
body: <p>The question is very simple but I can't manage to find a good solution to it. I have a LinearLayout in my activity. Depending on what the user does I need to make the background of my Layout blink 3 times. This means it will change the Background Color from transparent to Red and backwards for 3 times. Let me give you an example:</p>
  
  <ol>
  <li>the user receives a question and 2 buttons with answers</li>
  <li>the user presses the wrong answer. The layout containing the button will change it's background (Transparent - Red, Transparent - Red, Transparent - Red - Transparen) three times.</li>
  </ol>
  
  <p>How can I make this in Android ? Thank you.</p>
