Android SQLite數據庫安裝錯誤？

我已經建立了一個SQLite數據庫。似乎當我運行需要訪問它的類時，應用程序崩潰。最初有人向我指出，表格創建聲明是問題，但在解決錯誤之後，它仍然無法工作。數據庫設置爲： -Android SQLite數據庫安裝錯誤？

，但我不不到哪它指的是每次調用字段bmi時似乎都沒有問題。有什麼我失蹤？

沒有這樣的列：在你的數據庫中的BMI？ – 2012-04-06 17:24:23

是的，它指出了，但我已經在聲明中定義了dmi 'public static final String KEY_BMI =「bmi」; '，它用於創建語句'private static final String DATABASE_CREATE = 「create table goals（_id integer primary key autoincrement，」 +「code text not null，days text not null，」 +「bmi text not null ）;「; ' – 2012-04-06 17:29:16

您正試圖訪問數據庫中名爲「bmi」的列，但它不存在。

您最有可能在創建數據庫之後添加了列，並且未修改openHelper以正確升級數據庫。

添加「bmi」字段，錯誤將被解決。更改Create語句是不夠的，因爲數據庫已經存在，所以Create語句不會運行。您應該重寫「onUpgrade」以從一個數據庫版本更改爲另一個數據庫版本。

或者刪除當前的數據庫並從頭開始重新創建它。

但列bmi在那裏它是在這個創建語句'私有靜態最終字符串DATABASE_CREATE = 「創建表目標（_id整數主鍵自動增量，」 +「代碼文本非空，天文本不爲空，「 +」bmi text not null）;「;' – 2012-04-06 17:31:06

答覆已更新。往上看。「創建」語句僅在數據庫第一次創建時才運行。 – Kuffs 2012-04-06 17:33:29

好吧，它現在告訴我，'日期'列現在不存在。但是bmi和date從一開始就已經在數據庫中了 – 2012-04-06 17:40:14

您必須先取消靜置然後重新安裝應用程序，因爲如果您未實現onUpgrade，則android不會更改數據庫。

或轉到設置和您的應用程序，並清除您的應用程序的數據，然後運行您的應用程序。
