当我尝试向 sqlite 数据库添加多行时发生错误。单排没有问题。此外，该应用程序因此在三星 Galaxy s2 上崩溃，但不是在 nexus 上。

下面是创建表的代码：

 private static final String DATABASE_CREATE = "create table "
        + TABLE_AWARDS + "(" + COLUMN_ID
        + " integer primary key autoincrement, " + COLUMN_TITLE
        + " text not null, " + COLUMN_DESCRIPTION + " text not null, "
        + COLUMN_TYPE + " integer not null, " + COLUMN_ACHIEVED
        + " integer not null " + ");";

以及将行插入表中的代码：

 private static final String DATABASE_INSERT = "INSERT into  awards (title, description, type, achieved) VALUES "
        + "('Speed maximum', 'Stay', 1 , 0),"
        + "('Speed maximum', 'under 130 km/h', 2 , 0);";

根据你给我的stackoverflow问题的答案，语法应该是：

private static final String DATABASE_INSERT = "INSERT into  'awards' "+
        "SELECT 'Speed maximum' AS 'title', 'under 150 km/h' AS 'description', 1 AS 'type', 0 AS 'achieved'"
            +" UNION SELECT 'Speed maximum', 'under 130 km/h', 2 , 0"
            +" UNION SELECT 'Speed maximum', 'under 100 km/h', 3 , 0";

但这也不起作用。

在 Eclipse 中进入调试模式，在查询后放置一个断点，并在运行时查看 DATABASE_INSERT 之类的字符串的值，将其发布到此处，或者您可以在此处查看错误本身。
