title: Text blinking in Android, with most concise Kotlin
body: <p>I need to make some text (currently in a <code>TextView</code>) blink for a few seconds. There's several answers on <a href="https://stackoverflow.com/a/11991435/4433326">how to do it in java here</a>, but since Kotlin has some syntax/language features that java doesn't, I'm asking what is the most concise way you found to make text blink on Android using Kotlin.</p>
  
  <p>While I'm aiming at making a fading/smooth blink, I'm open to approaches that would make a non smooth blink too.</p>
  
  <p>Note that I'm also looking at lightweight code performance wise.</p>
  
  <p>Thanks for your answers!</p>
