Question

我关注此1，2此3。我有RecyclerView CardView。我使用Chronometer添加了一个计时器。应用程序的工作方式如下：

绿色CardView的第一个条件。当用户选择一个时，颜色变为黄色。

如果00:30:00（HH：MM：SS）中的计时器CardView的颜色再次变为蓝色，我想要make。当计时器在01:00:00（HH：MM：SS）时，CardView的颜色再次变为布朗。

我跟随那位导师（上图）但是当我向下滚动RecyclerView时，计时器（Choronometer）再次变为00:00:00。我不知道哪里错了。

任何答案对我都有帮助。先谢谢
