更改您的create table查询，因为它在所需位置没有空格。再次运行你在应用程序中的插入。

String CREATE_STUDENTS_TABLE = "CREATE TABLE IF NOT EXISTS "
                + TABLE_STUDENTS + "("
                + KEY_ID + " INTEGER PRIMARY KEY, "
                + KEY_NAME +" TEXT, "
                + KEY_CLASS + " TEXT, "
                + KEY_PARENT + " TEXT, "
                + KEY_STATUS + " TEXT, "
                + KEY_ADDRESS + " TEXT, "
                + KEY_SEX + " TEXT, "
                + KEY_PARENT_NO +" TEXT );";

SQLite数据库错误找不到列studentName
