這從我以前的問題here繼續。我已經爲數據庫做了代碼，但是當我運行我的應用程序時，它不會創建數據庫。我不知道我錯在哪裏，但在eclipse中，我的代碼不顯示任何錯誤。這裏是我的應用程序中的代碼。數據庫SQLite無法創建？

我應該做些什麼來使應用程序可以解析xml並存儲到SQLite。我的代碼有問題嗎？或者我應該更改我的代碼？
配售代碼這麼多的量不會幫你解決問題。張貼一段代碼是relavent – Pragnani 2013-05-12 16:00:15
你應該添加這樣的代碼，你得到的東西。 – 2013-05-12 16:02:17
對不起，我是編程新手，所以我沒有信心發佈一段代碼，因爲我擔心如果每個人都不明白我想要什麼 – endhare 2013-05-12 17:30:59
