Android對話框通過單獨的類存儲和訪問

Question

我遇到了與android對話框有關的堆棧溢出錯誤。我使用showDialog（DIALOG1）在一個語句中包含了大約21個對話框。當對話框和主要活動都包含在同一個類文件中時，顯示對話框效果很好，但是一旦我將對話框移動到另一個類文件並嘗試從主活動訪問它們，就會導致堆棧溢出錯誤。我試過在對話框類中擴展Dialog類以及擴展包含對話框的類（主要活動擴展了classOfDialogs）。我似乎無法讓對話從另一個文件訪問。有什麼建議麼？任何幫助將不勝感激！謝謝！！

它看起來像你遞歸調用該活動的對話框。

AlphaAthensActivity(Activity).<init>() line: 679  
AlphaAthensActivity(Dialogs).<init>() line: 13 
AlphaAthensActivity.<init>() line: 55 
AlphaAthensActivity(Dialogs).<init>() line: 36 
AlphaAthensActivity.<init>() line: 55 
AlphaAthensActivity(Dialogs).<init>() line: 36 
AlphaAthensActivity.<init>() line: 55 

爲了避免運行內存的應用程序，這將引發異常。我認爲你需要重新設計你的代碼。一個更好的主意是將對話框放在一個共同的基類中並且擴展它。
