I recently faced similar problem. In my case it was easier to create final array (or collection) and to add variable, that I wanted to change inside anonymous class, to this array, as below.

   array[0] = a;
   new Runnable() {
       @Override
       public void run() {
           array[0] += 3;
       }
   };
