you use handler postdelayed method. this:

    handler h = new handler();     int count = 0;     runnable r=new runnable()     {         public void run()          {             if(count < 6){                 if(count % 2 == 0){                     count++;                     layout.setbackground(red);                     h.postdelayed(r,500);                 }else{                     count++;                     layout.setbackground(transparent);                     h.postdelayed(r,500);                 }             }          }      };     h.post(r);
