通过单独的类存储和访问的 Android 对话框

Question

我遇到了与 android 对话框相关的堆栈溢出错误。我在使用 showDialog(DIALOG1); 的 which 语句中包含大约 21 个对话框。当对话框和主要活动都包含在同一个类文件中时，显示效果很好的对话框，但是一旦我将对话框移动到另一个类文件并尝试从主要活动中访问它们，就会导致堆栈溢出错误。我尝试在对话框类中扩展 Dialog 类以及扩展包含对话框的类（主要活动扩展 classOfDialogs）。我似乎无法让从另一个文件访问的对话框正常工作。有什么建议么？任何帮助将不胜感激！谢谢！！

看起来您正在递归调用此 Activity 的 Dialog。

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 

为避免应用程序内存不足，抛出此异常。我认为你需要重新设计你的代码。一个更好的主意是将对话框放在一个公共基类中并对其进行扩展。
