推荐答案

要保存你的分数，你可以做这样的事情：

To save your scores you can do something like this:

// prepare the data: put the String values of the scores of the first 3 users
// in one String array for each level
String[] firstLevelHighscores = new String[] { 
    firstUserLevel1Score, secondUserLevel1Score, thirdUserLevel1Score 
};
String[] secondLevelHighscores = new String[] { 
    firstUserLevel2Score, secondUserLevel2Score, thirdUserLevel2Score 
};
String[] thirdLevelHighscores = new String[] { 
    firstUserLevel3Score, secondUserLevel3Score, thirdUserLevel3Score 
};

// now save them in SharedPreferences
SharedPreferences sharedPref = getSharedPreferences("LevelScores", 
        Context.MODE_PRIVATE);
Editor editor = sharedPref.edit();
editor.putStringSet("level1", firstLevelHighscores);
editor.putStringSet("level2", secondLevelHighscores);
editor.putStringSet("level3", thirdLevelHighscores);

请注意，你可以把更多的用户的恩怨到字符串数组。如果您需要保存的分数多层次，您只需创建多个阵列。

Note that you can put even more user's scores into the String array. And if you need to save scores for more levels, you simply create more arrays.

要从共享preferences检索保存的数据，你这样做是这样的：

To retrieve the saved data from SharedPreferences, you do it like this:

SharedPreferences sharedPref = getSharedPreferences("LevelScores", 
        Context.MODE_PRIVATE);
String[] firstLevelHighscores = sharedPref.getStringSet("level1", null);
String[] secondLevelHighscores = sharedPref.getStringSet("level2", null);
String[] thirdLevelHighscores = sharedPref.getStringSet("level3", null);

我假设你能够 INT 转换为字符串，反之亦然。希望它为你这样的。

I assume you're able to convert int to String and vice versa. Hope it works for you this way.
