如何在Android Studio中變量發生變化時進行設置？

Question

a1.setClickable(false); 
       a2.setClickable(false); 
       a3.setClickable(false); 
       b1.setClickable(false); 
       b2.setClickable(false); 
       b3.setClickable(false); 
       c1.setClickable(false); 
       c2.setClickable(false); 
       c3.setClickable(false); 
       new Handler().postDelayed(new Runnable() { 
        @Override 
        public void run() { 
         a1.setClickable(true); 
         a2.setClickable(true); 
         a3.setClickable(true); 
         b1.setClickable(true); 
         b2.setClickable(true); 
         b3.setClickable(true); 
         c1.setClickable(true); 
         c2.setClickable(true); 
         c3.setClickable(true); 
        } 
       }, 5000); 

在上面的代碼中，我想刪除時間5000，並希望它在每次變量值變化時設置爲可點擊。

       b2.setClickable(false); 
       b3.setClickable(false); 
       c1.setClickable(false); 
       c2.setClickable(false); 
       c3.setClickable(false); 
       new Handler().postDelayed(new Runnable() { 
        @Override 
        public void run() { 
         a1.setClickable(true); 
         a2.setClickable(true); 
         a3.setClickable(true); 
         b1.setClickable(true); 
         b2.setClickable(true); 
         b3.setClickable(true); 
         c1.setClickable(true); 
         c2.setClickable(true); 
         c3.setClickable(true); 
         change = true ; 

        } 
       }, 5000);
