用AlertDialog / Dialog模拟子菜单

2 个解决方案

How about this - when you create AlertDialog 2, pass in the context of AlertDialog 1, using dialog.getContext() (instead of, say, passing in the original Activity ).. and so on? 怎么样-当您创建AlertDialog 2时，使用dialog.getContext()传递AlertDialog 1的上下文（而不是传递原始的Activity ）。等等？ I believe that would make AlertDialog 2 "appear over" AlertDialog 1. Cancelling dialog 2 or pressing back button should take you back to dialog 1. 我相信这会使AlertDialog 2“出现”在AlertDialog 1上。取消对话框2或按返回按钮应该使您返回到对话框1。

You could extend the same notion to dialog 3 (ie, pass in the context of dialog 2 while creating dialog 3) .. and so on. 您可以将相同的概念扩展到对话框3（即，在创建对话框3时传入对话框2的上下文）等等。

why dialogs? 为什么要对话？

i think, it is possible to call multiple dialogs. 我认为，可以调用多个对话框。

but i would suggest (though unconventional) you can have PreferenceActivity which can nest menus. 但我建议（尽管是非常规的）您可以拥有可以嵌套菜单的PreferenceActivity 。 remember setting pages. 记住设置页面。

and for blocking the main UI (if you want) you can invoke the activity with a dialog theme . 为了阻止主用户界面（如果需要），您可以使用对话框主题调用活动。

this will be easier to code and maintain. 这将更易于编码和维护。 and you can have your back button as well. 您也可以使用后退按钮。

you can call activity for result and get the result in the main activity. 您可以为结果调用活动，并在主活动中获取结果。
