我有一個數據插入到我的sqlite數據庫的問題。我通過互聯網獲取JSON數據，並試圖將該數據放入sqlite數據庫，但它扔我constraint failes error。我知道這意味着我已經插入相同的數據，或者至少使用相同的ID，但是當我從模擬器查看數據庫時，該表是空的，並且沒有數據。下面是我'使用的代碼：Android的Sqlite數據庫 - 約束失敗

UserDbHelper類是我的數據庫幫助class.I'm用它來把數據sqlite.I對其他表沒有任何問題。我可以用類似的代碼將它們的數據放在這裏，但收藏表只是不想工作。
那麼，任何建議/幫助或其他可以幫助我解決我的問題？ 謝謝！
實際上這是問題...謝謝你的幫助/建議 –
