Say I was making a fitness app where you can make your out workout. When you have configured the workout you would want to save it. How do I add this function so that when he exits the app and opens it again, he can view his workouts?

我专门在Android上工作.

推荐答案

我相信Kivy具有处理此问题的模块.尽管它仍(在撰写本文时)仍处于实验阶段.在这里查看: http://kivy.org/docs/api- kivy.storage.html#module-kivy.storage

I believe Kivy has a module that deals with this. Though it is still(at the time of writing) experimental. Look here: http://kivy.org/docs/api-kivy.storage.html#module-kivy.storage

根据此，他们似乎正在使用Pickle来存储数据.

如果由于某种原因该方法不起作用， 自己使用Pickle/cPickle怎么办?如果您不知道这些是什么，请立即将其搜索. 然后，您可以将用户设置或锻炼内容存储在字典中，然后对该字典进行腌制，保存 sdcard中的信息作为一个简单的文本文件，根本就不会占用太多空间.

If that doesn't work for some reason, what about using Pickle/cPickle yourself? If you don't know what those are, Google them now. Then you could store user settings or workouts in a dict and pickle that dict, saving the info to the sdcard as a simple text file, which shouldn't take up much space at all.

据我所知，由于使用C或可能的Cython编写，因此cPickle是Pickle的更快实现，我不确定.希望对您有所帮助.

As far as I know, cPickle is a faster implementation of Pickle due to being written in C or possibly Cython, I am not sure. Hope any of this helps.

值得注意的是，可以将文本文件保存到Android设备.最近，我在Kivy上做了一个游戏，就是以纯文本格式存储高分.

It's worth noting that it's possible to save text files to the Android device. I recently made a game with Kivy where I was doing just that, storing high scores in plain text.
