保存玩家数据和状态 [英] Saving player data and status

问题描述

我制作了一个Android游戏，我想知道如何保存玩家的数据，例如金钱，达到的等级等.我认为XML并不是实现此目的的真正方便的方法.有什么好办法吗? android是否提供某种保存数据的方法?

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?

推荐答案

对于您需要跟踪的数据类型，数据库可能是过大的.我建议使用Android的SharedPreferences API. 请参阅此处以获取教程.

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.

这是 Android数据持久性方法的官方概述，其中包括SharedPreferences和SQLite.

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

检出

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

对于字符串集不存在的val:

For non-existent vals for the string set:

返回首选项值，如果它们 存在或defValues.投掷 ClassCastException如果存在 这个名字不是 一组.

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

对于不存在的值数据，例如字符串，布尔值，浮点数等:

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

返回首选项值(如果有) 存在或defValue.投掷 ClassCastException如果存在 这个名字不是 字符串.

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