這篇文章主要為大家詳細(xì)介紹了Android實現(xiàn)京東秒殺界面，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了Android實現(xiàn)京東秒殺界面展示的具體代碼，供大家參考，具體內(nèi)容如下

效果圖：

京東秒殺是兩個小時一個場次，判斷本機的時間進(jìn)行場次定時，然后在這兩個小時里面進(jìn)行倒計時。

      } else {
        miaosha_second.setText("0" + second + "");
      }


    } catch (ParseException e) {
      e.printStackTrace();
