Sqlite Fehlercode 1, msg Syntax Fehler

Question

Von dem, was ich sagen kann, scheint es wie es die addTask contentvalues ​​in der falschen Reihenfolge übergeben, aber ich sehe nicht warum. Die addUser-Methode wird auf die gleiche Weise implementiert und funktioniert einwandfrei.

Der Fehler, den ich bekomme und alle relevanten Code ist hier. Jede Hilfe wird geschätzt.

Answer 1

Der Fehler erscheint in Ihrem TASK_KEY_USERID zu sein, wie Sie einen Raum im Wert haben. Sollte es vielleicht ein Unterstrich sein? Eine weitere Anmerkung, die hinzugefügt werden soll, ist, dass Android Ihren primären Schlüsselspaltennamen mag, um in "_id" zu enden, welches Ihr nur "Identifikation" ist.
