表沒有列名爲-Sqlite - android - 我的第一個應用程序

Question

是的，我已經閱讀了許多許多答案，並嘗試了所有，但沒有爲我工作。我不知道什麼是錯的，因爲根據我的看法，一切都很好。

很多時候我改變了DB版本。即使我重命名數據庫和表名稱，但沒有任何作品。我可以打印顯示正確結果的日誌，但爲什麼它沒有插入到數據庫中。

也當我從表中刪除所有複選框字段然後數據插入工作。

一個不起眼的request..please不從詢問的問題，因爲這問題是別人問了很多次，我嘗試了所有的解決方案，但沒有奏效阻止我。

請指導我，因爲我對Java和Android Studio完全陌生。

有時，錯誤的是：

table tblCinFormNew has no column named chkbox_other 

有時，錯誤的是：

table tblCinFormNew has no column named chkbox_cosmo 

這裏是我的數據庫處理器類：

Answer 1

你缺少逗號（，）在CREATE_CONTACTS_TABLE查詢

KEY_ZIP 「TEXT」 後+ 「TEXT」 + KEY_SALOON + 「TEXT」 + KEY_COSMO + 「TEXT」 + KEY_STUDENT + 「TEXT」 + KEY_OTHER + 「TEXT」 + KEY_ADD_INFO + 「TEXT」

做此更改後嘗試。它應該能夠工作，如果您仍然遇到此錯誤，請使用Android設備監視器檢查您的表格結構，如果您正在使用仿真器並調試您的代碼。
