Highlight buttons one at a time
<p>I am making an Android game modeled after the old Simon game. It is a little different in the layout as it is using a 3x3 layout of buttons. I am trying to get the buttons to light up one at a time inside the loop that randomly selects a button. The trouble I have is that all of the buttons light up at once and only the last (or first, not sure) changes back to the original color. I have tried very thoroughly to find an appropriate answer to my situation but have had no luck here or elsewhere. The button id(s) are in the butts[]. butts[0] is button 1, butts[2] ... Below is my attempt.</p>

<pre><code>public void play()
{
  for(int x = 0; x &lt;= numButtons; ++x)
  {
      spot = randomGenerator.nextInt(9);
      playMe[x] = spot;
      //butts[spot].setBackgroundColor(Color.parseColor("#540115"));
      handler.postDelayed(new Runna(spot), (x+1)*1000); 
  }
}
class Runna implements Runnable 
{ 
  public Runna(int j2) 
  {
      butts[j2].setBackgroundColor(Color.parseColor("#540115"));
  }
  public void run() 
  {  
    butts[spot].setBackgroundColor(Color.LTGRAY);
  }
}
</code></pre>
