Answer 1

用逗号分隔值，例如

 " (id INTEGER PRIMARY KEY AUTOINCREMENT, "
    + "user_name TEXT NOT NULL, "

还在每个逗号后面设置一个空格。

Answer 2

您需要使用逗号分隔列声明。

public static final String CREATE_USER_DETAILS_TABLE = " CREATE TABLE "
    + "user_details_table (" 
    + "id INTEGER PRIMARY KEY AUTOINCREMENT, "
    + "user_name TEXT NOT NULL, " 
    + "password TEXT NOT NULL, "
    + "sex TEXT NOT NULL, " 
    + "email TEXT NOT NULL, "
    + "remember_me TEXT ); ";

P.S。：为了避免下次发生反击，您可能想要问一个问题。这比仅仅转储代码和日志更友好。
