问题 Can you overlay a view on top of everything in android? In iPhone I would get the new view set its frame.origin to (0,0) and its width and height to the width and height of self.view . Adding it to self.view would then cause it to act as an overlay, covering the content behind (or if it had a transparent background then showing the view behind). Is there a similar technique in android? I realise that the views are slightly different (there are three types (or more...) relativelayout,

问题 I have a page for creation of dynamic entities. <%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> ...

问题 In my code, when a view disappears, a specific action occurs. I am doing it through the viewDidDisappear() function. I have a specific button that when is pressed it goes to another view. I was wondering in what I way I could tell ONLY the function caused by a specific button to skip the viewDidDisappear() .

问题 I am using Hibernate by implementing "Open Session in view" pattern?It opens a new connection per request. Is there any way to use the existing connection? Is my understanding correct?

Intended for the "Open Session in View"
