第五版 11-11
" 打開 『res/layout/activity_main.xml』 ... 這裡, 是不是寫錯檔案名了 ???
從 11-6 道這裡的描述有點紊亂, 還望有機會下版修改一下
Widget不能用?
您好，我看了您的書，覺得獲益良多
但是在倒數第二章的地方 (製作widget)
理論上應該是"把widget拖到桌面→按下widget圖示→顯示出BMI_calc的畫面"
然而我照您的方法做
按下widget圖示之後就毫無反應
直接使用您的code也是一樣結果
不曉得您有無這樣情況呢?
謝謝
第五版的錯誤
您好,
想反應一下關於書中的錯誤,
尤其28章以後資料庫部分, 常有書中程式碼參數，與書中文字描述，或是附帶code不同的狀況. EX:
30章: DATABASE_NAME 與DATABASE_TABLE的程式碼定義錯誤, 導致前後文不一
31-3-1: 結尾的position參數修正, 於後面章節並未詳述, 而是於程式碼直接將position改為id
34章: 範例程式碼未包含34-3內容, (僅包含至34-2)
第五版感覺被刪改的有點紊亂，流暢度受影響有點可惜了, 希望能於後續版本修正
能持續翻修本書內容著實不容易, 再次感謝提供台灣讀者一本好書
