我目前正在学习 android 应用程序开发,并且处于起步阶段。我构建了这个游戏,现在我想在我的屏幕上设置商店并将高分显示为 Textview。如果有人可以帮助我,我将不胜感激。谢谢!

基本上这是程序:

  1. 创建 SharedPreferences 和 SharedPreferences.Edit 的实例SharedPreferences sharedPref = .... AND SharedPreferences.Edit editor = .....
  2. 在游戏结束的地方调用它if (sharedPref.getInt("highscore",0) < clicks) { editor.putInt("highscore",clicks).apply() }

上面的代码将首先检查你保存在“highscore”键中的最后一个分数,如果你当前的点击次数更高,它将用它替换它,如果这是第一场比赛,那么默认值将被视为 0,所以第一场比赛的分数将被保存为高分,除非它再次为 0。

我制作了几乎相同的游戏,它的 Taplay 和 PlayStore 顺便说一句。

祝你好运。

您可以使用 SharedPreferences,如果您想跟踪用户游戏统计信息,我建议您使用Sqlite 。
