樣本只是有一個按鈕「創建數據庫」。但是當我點擊按鈕，它brokedown.I不知道什麼是錯的，我從來沒有學過SQL，以上這些代碼都是來自book。我想念什麼？或者我的代碼有什麼問題？謝謝。

Answer 1

除非它是一個錯字，當你在這裏輸入它 - 你拼寫爲「創建」錯誤

Answer 2

請寫出創建像

public static final String CREATE_BOOK = "create table book (" 
     + "id integer primary key autoincrement, " 
     + "author text, " 
     + "price real, " 
     + "pages integer, " 
     + "name text)";
