我试图删除一对夫妇行的SQLite数据库编程Android和想知道什么whereArgs是指本文档中：

I'm trying to remove a couple of rows in a sqlite database programmatically for android and am wondering what the whereArgs are referring to in this documentation:

http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html#delete(java.lang.String,%20java.lang.String,%20java.lang.String[])

有人可以给我一个例子吗？

Can someone give me an example?
