我得到的錯誤close（）從來沒有明確地調用一次又一次啓動應用程序。我不明白我在哪裏錯了數據庫。close（）從來沒有顯式調用數據庫'/ data

你爲什麼要評論'db.close（）;'？ – pgiitu

它的工作原理！但運行2到3次後又得到同樣的問題。 – androidTag

它位於相同的地方還是不同的功能？ – pgiitu

看到你的代碼，我於是後我會建議一種不同的方法，第一種方法是在每次打電話後我都說你應該close()。

我看到一個數字的代碼中的問題，以下是一些建議：

  • 爲什麼ü做dbhelper = new MyDbHelper(this);多次？您應該只在onCreate
  • 中執行一次此外，您還可以創建成員變量SQLiteDatabase db，然後在onCreate中執行db= dbhelper.getWritableDatabase();。
  • 從onDestroy()方法中刪除除db.close()之外的所有其他呼叫。
  • 刪除對dbhelper.getReadableDatabase();和dbhelper.getWritableDatabase();所有來電，因爲你已經從onCreate方法，你可以從任何地方在您的活動使用有一個實例db

所以基本上我想說的是，你剛纔得到的writable數據庫實例在onCreate中一次，然後在onDestroy中關閉它。

感謝它的作品現在!!!! – androidTag

再一次，我得到相同的錯誤= IllegalStateException：嘗試重新打開已關閉的對象：SQLiteDatabase：/data/data/com.example.tazeen.classnkk/databases/ClassNKK – androidTag

你是否在任何地方調用close（）別的呢？ – pgiitu

什麼是您的logcat拋出：

android.database.sqlite.DatabaseObjectNotClosedException：應用 沒有關閉在 android.database.sqlite.SQLiteDatabase這裏打開遊標或數據庫對象。

無需註釋db.close()。啓用此：
Android error - close() was never explicitly called on database
