Question

我有一个有问题的申请。在回答完所有问题后，分数将被保存。问题是应用程序添加旧分数。

例如：

第一次参加练习：得到了5分第二次参加练习：我获得了10分（我应该得到5分，但应用程序会增加旧分数）。第三次参加练习：我得到14分（我应该得到4分，但应用程序会增加旧分数）。

所以，在这种情况下，我必须首先退出应用程序，然后再次运行它以获得我想要的内容，如果没有，那么它会不断添加旧分数。

有没有人知道这个问题？我使用包含android库和sqlite的java。

检查变量的初始化。您可能只需要将值设置为0.它与Android无关，我认为

分数不断增加（旧分数+当前分数），android
