android – 通过带有重音字符的列排序sqlite的问题(Á)

我有一个sqlite数据库,我需要通过一个有一些以重音字符开头的单词的列来排序.这些物品订购错误,它们出现在结果的最后：

安东尼奥
BONZO
Zeto
安吉拉

当sqlite数据库在该列中有重音时,如何正确订购？

谢谢

解决方法

或

... ORDER BY column COLLATE UNICODE

要么

... ORDER BY column COLLATE LOCALIZED

Reference:

In addition to sqlite’s default BINARY collator,Android supplies two more,LOCALIZED,which changes with the system’s current locale,and UNICODE,which is the Unicode Collation Algorithm and not tailored to the current locale.

例：

db.execsql("CREATE TABLE foo(a TEXT);");
db.execsql("INSERT INTO foo VALUES('Antonio'),('Bonzo'),('Zeto'),('Ángela');");

Cursor c = db.rawQuery("SELECT * FROM foo ORDER BY a COLLATE UNICODE",null);
while (c.movetoNext()) {
   Log.d("foo",c.getString(0));
}

输出：

Ángela
Antonio
Bonzo
Zeto
