Android,共享偏好还是内部存储？

我想存储一些基本数据,如players_name,levels_completed,faster_speed,faster_time,并在每次玩家开始我正在制作的愚蠢小游戏时启动它……这是执行此操作的常用方法吗？

Sharedprefs还是内部存储？

我现在是http://developer.android.com/guide/topics/data/data-storage.html
并且对于使用哪个看起来既好又容易做就感到困惑.

建议？

谢谢！

解决方法:

这几乎取自其中一个Facebook sdks示例(它允许您保存FB会话,因此用户不必每次都登录)…我会稍微为您修改它

public class SessionStore {

private static final String PLAYER_NAME = "player_name";
private static final String LEVELS_COMPLETED = "levels_completed";
private static final String HIGH_SCORE = "high_score";

private static final String KEY = "player_session";

int highScore;
int levelsCompleted;
String pName;

public static boolean saveSession(Context context, String player_name, int levels_completed, int high_score) {
    Editor editor =
        context.getSharedPreferences(KEY + player_name, Context.MODE_PRIVATE).edit();
    editor.putString(PLAYER_NAME,player_name);
    editor.putInt(LEVELS_COMPLETED, levels_completed);
    editor.putInt(HIGH_SCORE,high_score);

    return editor.commit();
}

public static void restoreSession(Context context, String player_name) {
    SharedPreferences savedSession =
        context.getSharedPreferences(KEY + player_name, Context.MODE_PRIVATE);
    highScore = savedSession.getInt(HIGH_SCORE,0);
    levelsCompleted = savedSession.getInt(LEVELS_COMPLETED,0);
    pName = savedSession.getString(PLAYER_NAME,"NO_NAME!");

}

public String getName()
{
      return pName;
}

}

我想你得到的基本想法……

一些要点：我使用“KEY player_name”以防不同玩家在同一部手机上播放(如果它是静态的,你会用其他数据覆盖一个玩家的数据).

此外,当你执行pName = savedSession.getString(PLAYER_NAME,“NO_NAME！”);如果共享首选项中不存在任何内容,则默认值为“NO_NAME！”同样对于getInts(在这种情况下,我将它们默认为0)

在程序中你会做SessionStore.saveSession(“Alex”,50000,50000);希望这给出了如何使用它的好主意……还要记住我是一个新手 – 这对我来说很有用但我不是专家：D
