推荐答案

根据数据，你需要救世主，你可以在传递数据（如果它的基本类型）到活动的套件，覆盖的的的onPause方法活动。每当活动关闭的onPause方法将被调用。

Depending on the data you need to savior you could pass in the data (if it's primitive types) into the Bundle of the Activity and override the onPause method of the activity. The onPause method will be called whenever the Activity closes.

请参阅参考 http://developer.android.com/活动的生命周期参考/安卓/应用/ Activity.html

有其他的方式来保存数据 - 你可以直接把它写在SD卡上的文件，然后在的onPause方法关闭流如果该活动是由操作系统关闭没有完成数据

There are other ways to save the data - you could write it directly to a file on the SD card and then close the stream in the onPause method if the Activity is closed by the OS without finishing the data.

那么活动开启时再次调用活动的onResume方法和读取保存的捆绑或写入到SD卡里面的文件中的数据。

Then when the Activity is opened again you call the onResume method of the Activity and read the data saved inside the Bundle or the file written to the SD card.
