如何在Android上保存临时数据？ [英] How do I save temporary data on android?

问题描述

如何保存一些临时数据，以便在关闭应用程序时所有数据都消失了？我尝试了sharedPreferences，但是当我再次打开应用程序时，数据似乎仍然存在。

How can I save some temporary data so that when I close the application all the data is gone? I've tried sharedPreferences but it seems that the data is still there when I open up the application once again.

我听说您可以将数据保存到某些缓存中内存，但我真的不希望在应用程序仍在启动和运行时如果内存已满，数据就不会丢失。也许我应该使用一些全局变量？

I've heard that you can save data to some cache memory, but I really don't want the data to be gone if the memory gets "filled" when the app is still up and running. Maybe I should go with some global variables? Not that I know how I could get that to work.

我的简单应用程序是一个游戏，当您更进一步时，它会打开并关闭活动。这基本上是一个充满愚蠢图片^^的游戏。在一个活动中完成的工作应该保存在某个地方，因此，如果我回去，我可以加载数据并使它看起来像活动结束前一样。我希望你能理解我的意思。

My simple app, which is a "game", opens up and closes activities when you go one step further. It's basically a game filled with stupid pictures ^^. Stuff that has been done in one activity should be saved somewhere, So if i go back I can load the data and make it look like it was before the activity was closed. I hope you understand what I'm saying..

任何想法我如何存储一些在您需要时也易于访问的信息。

Any ideas how I could store some information that is also easy accessible when you need it.

推荐答案

使用全局变量。

在 onCreate 定义变量，例如：

int i;
或
String s = myString

然后，您可以在任何函数中访问/更改它们。

Then you can access/change them in any function.

希望我帮助了：）
