共享首选项中的前5个整数

Question

我想在共享首选项文件中获取前5个整数。我所拥有的只是将35个数字与密钥放在共享首选项文件中，我想要前5个。我需要将它们放在另一个活动中，这就是我使用共享首选项的原因。前5个数字可能会改变，我希望数据永久保存。数字更改的方式是复选框，如果用户点击复选框，则该键的编号会增加。如果有更好的方法来编写代码或者您有解决方案，请在下面写下来吗？

如果您需要在其他活动中发送数据，我建议您使用Intent系统。 Here's a link to help you on that

意图系统比读取和写入用户设备上的文件要快得多。您也可以将整个对象传递给它，并且比使用上面使用的共享首选项方法容易得多。

从intent /中得到所有整数之后，你会将所有整数拉出到一个数组中并使用辅助方法返回一个包含5个数字的int数组，找到前面提到的前5个数字{ {3}}，然后无论何时需要获取数组中的前5个数字，请在您喜欢的任何数组上调用辅助方法。
