switch case 忘记 break

昨天纠结了很久的问题,一直找不到原因,早上发现是一个低级错误:

 private void selectButton(int id) {
         switch (id) {
         case 0:
             recommend_button.setEnabled(false);
             recommend_button.performClick();
             break;
         case 1:
             hotspot_button.setEnabled(false);
             hotspot_button.performClick();
             break;
         case 2:
             tieba_button.setEnabled(false);
             tieba_button.performClick();
             break;
         case 3:
             bottom_tv.setEnabled(false);
             bottom_tv.performClick();
             break;
         case 4:
             bottom_social_friends.setEnabled(false);
             bottom_social_friends.performClick();
             break;
         case 5:

             if(isFromWaterFallActivity){
                 bottom_publish.setEnabled(false);
                 bottom_publish.performClick();
                 isFromWaterFallActivity = false;
             }else{
                 recommend_button.setEnabled(false);
                 recommend_button.performClick();
                 isFromWaterFallActivity = true;
             }
             break;
         default:
             break;
         }

由于switch  中间的某几个 case 忘记加上 break;引发的问题,在此明示!
