是否共享preferences使用特定的字符集？ [英] Does SharedPreferences use a certain character set?

问题描述

我刚才注意到，共享preferences存储字符串时删除回车（\\ r）的。由于这是相当昂贵的我不知道这一点，我想知道，如果它删除任何其他字符。换句话说，它使用某个字符集。

 共享preferences SP = activity.getShared preferences（preferences，Context.MODE_PRIVATE）;
。sp.edit（）putString（富，\\ r \\ nfoo）提交（）。//后重新启动应用程序
共享preferences SP = activity.getShared preferences（preferences，Context.MODE_PRIVATE）;
字符串sFoo = sp.getString（富，）; //返回\\ nfoo，而不是\\ r \\ nfoo
 

解决方案

早上好

这是更坏：如果您存储字符串为\\ r到共享preF，杀戮和重新启动应用程序后，从共享preF值将变成\\ n

这是我们敬爱的Andr​​oid平台的另一个错误，很讨厌...

干杯

I have just noticed that SharedPreferences removes carriage return (\r) when storing a string. Since it was quite costly for me to not know this, I would like to know if it removes any other characters. In other words, does it use a certain character set.

SharedPreferences sp = activity.getSharedPreferences("preferences", Context.MODE_PRIVATE);
sp.edit().putString("Foo", "\r\nfoo").commit();

//After restarting the app
SharedPreferences sp = activity.getSharedPreferences("preferences", Context.MODE_PRIVATE);
String sFoo= sp.getString("Foo", ""); //returns "\nfoo", not "\r\nfoo"

解决方案

Good morning,

It is even worst: if you store the String "\r" into SharedPref, after killing and restarting application, the value from SharedPref will become "\n".

Another bug from our beloved Android platform, very annoying...
