我目前正在將我的應用程序轉換爲碎片，並遇到了一些問題。我希望能夠在你的幫助下解決所有問題，並且一旦我解決了轉換的某個部分，我將編輯我的帖子。Android的碎片問題（轉換我的應用程序）
第一個問題： AlertDialogs。當用戶點擊一個按鈕時，可能稍後會出現一個ListView項目，它們會顯示一個AlertDialog以選擇他們想要查看的帳戶。我爲Facebook和Twitter做了這個。然而，雙層結構混淆了我，ListDialog似乎以不同的方式加載其內容。
所以，我的活動代碼：

的錯誤是在：
- .create();第一個對話框，它說
Syntax error on token "create", Identifier expected after this token
Syntax error, insert ";" to complete MethodDeclaration
Syntax error, insert ";" to complete ReturnStatement
Syntax error, insert ")" to complete MethodInvocation
Syntax error, insert "}" to complete ClassBody
- MyAlertDialogFragment第一showDialog();，說MyAlertDialogFragment不能得到解決。
-In第二對話的初始化：
Syntax error on token ".", delete this token
The method setItems(CharSequence[], new DialogInterface.OnClickListener(){}) is undefined for the type External.MyFBAlertDialogFragment.MyAlertDialogFragment
Type mismatch: cannot convert from AlertDialog.Builder to Dialog
然後還對從builder創建第二對話框：builder cannot be resolved。這個顯然是合法的，但我沒有辦法解決。
它也抱怨資源目錄名稱無效。
我剛剛修復的最後一個問題:)。
我正在使用ABS，但這是ABS中的選項卡之一。這意味着它需要是一個片段，但不能顯示ActionBar。
你剛剛得到語法錯誤。 – Blundell 2012-04-20 14:31:31
