Is it possible for me to store and retrieve my ArrayList values using shared preference. Can anyone suggest me with an example.
回答1:
It looks like the closest the SharedPreferences can do is save a Set of Strings. If that doesn't suit you should probably look at the alternatives for persisting data.

You can refer to this : http://androidcodemonkey.blogspot.com/2011/07/store-and-get-object-in-android-shared.html (Thanks to Greg Zimmers that give this tutorial).
The idea is you encapsulate the ArrayList to an Object and then you can refer to link tutorial that I give above and follow the tutorial. If you want to retrieve the ArrayList, you can get the Object and then you retrieve the ArrayList from the Object.
