Saving player data and status

问题

I made an android game and I want to know how to save player data such as money, level reached, etc. I think that XML is not a really convenient way to do this. Is there any good way to do this? Does android provide some method to save the data?

回答1:

A database is probably overkill for the type of data you need to track. I would suggest using Android's SharedPreferences APIs. See here for a tutorial.

Here's an official overview of Android data persistence methods including SharedPreferences and SQLite.

Check out the getStringSet API for storage of arrays/collections.

For non-existent vals for the string set:

Returns the preference values if they exist, or defValues. Throws ClassCastException if there is a preference with this name that is not a Set.

For non-existent value data such as string, bool, float etc.:

Returns the preference value if it exists, or defValue. Throws ClassCastException if there is a preference with this name that is not a String.

Use a SQlite database. ( Data storage on developers.android )

Here is a tutorial that shows the functionality:
