Question

我目前正在学习Android应用程序开发并在最开始阶段。我建立了这个游戏，现在我想在我的屏幕上设置商店并将高分显示为Textview。如果有人能帮助我，我真的很感激。谢谢！

Answer 1

基本上这是程序：

创建SharedPreferences和SharedPreferences.Edit SharedPreferences sharedPref = .... AND SharedPreferences.Edit editor = .....
在游戏结束if (sharedPref.getInt("highscore",0) < clicks) { editor.putInt("highscore",clicks).apply() }

上述代码将首先检查您在＆＃34;高分＆＃34;中保存的最后得分。如果您当前的点击次数较高，它将替换它，如果这是第一个游戏，则默认值将被视为0，因此第一个游戏的得分将被保存为高分，除非它再次为0。

我已经制作了几乎相同的游戏，Taplay和PlayStore btw。

祝你好运。

Answer 2

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

存储最高分并显示它
