master-detail

问题 So I am new to Android development, and trying to wrap my head around the Master/Detail flow design. As such, I'm using the default classes Eclipse creates for you - so ScreenDetailActivity , ScreenDetailFragment , ScreenListActivity , and ScreenListFragment . One of my Detail fragments uses a layout that contains a series of checks and fields for entering data, and a button that is supposed to make the Activity class using the fragment pass that data to a calculator class, which then

问题 Newbie question here ... I've created a Master-Detail Application project in Xcode 4.2 using ARC and Storyboard. I've modified the template to be: MasterViewController.h #import <UIKit/UIKit.h> @class DetailViewController; @interface MasterViewController : UITableViewController { NSMutableArray *items; } @property (strong, nonatomic) DetailViewController *detailViewController; @property (strong, nonatomic) NSMutableArray *items; @end MasterViewController.m (snipits) .... @synthesize items; ..

问题 I am having the bellow described problem with getting UISplitViewController to work on xCode 7.1.1, iOS 9.1. I have implemented the Split VC with both master and detail being a navigation controller. I have a list of tasks and then a detail task view, also a 'add new task' VC. Everything works fine on iPhone, however when I try to run on iPad (any version) or iPhone 6+/6S+, I get the following issue. Initially when I select a task from Master VC, it will load in the same Master VC with a

问题 I have a master detail view that navigates a series of sequential lists using totally vanilla SwiftUI and I'm noticing two things. The list rows width jitters when you access one via navigation link? The .navigationBarTitle isn't visible until the new view is completely on screen? Seems like neither of these things are suppose to happen? Wonder if anyone has any ideas (video and code attached).

问题 I am creating a master detail page in Xamarin Forms. I want to have Menu icon on top left, searcher on the right and another label on the menu bar. Can some help help me with how I can be done? I added the menu icon. I want help with adding other controls on the toolbar/Menubar/Navigation bar what ever it is called. Its the bar on top of the master detail page.

问题 In Oracle APEX 5.1, I have an Interactive Grid Master-Detail page. The following series of steps (which users sometimes take) creates an unhandled exception (ORA-01403: no data found). User creates an invalid record in the master section and a corresponding record in the detail section. User attempts to save (row processing) and receives error due to invalid master record. Without deleting the invalid master record, user activates filters which remove invalid master record. User makes (valid)

问题 I've noticed that in a Master-Detail UISplitView iPhone app, I dont have one single instance of my DetailController and getting that reused by setting new content, instead it seems that on each segue/everytime I navigate to the Detail View, a new instance of DetailController gets created by the segue and has to be filled with content? Why is that? Through debugging I can see that there is at least one DetailController instance staying alive all the time but not used on iPhone, and everytime I

问题 (Xcode6-beta3, Swift, iOS8, iPad) In an iPad split-view controller, how do I link the Master View Controller to the Detail View Controller? In other words, when the user taps on an item on the left, how do I change the view on the right? I know that in didSelectRowAtIndexPath, I need to call a method... but how do I call a method in the Detail View Controller from the Master View Controller? Example Imagine an app to display information on different types of cheeses. We begin by dragging a

问题 I program a RSS reader with Master Detail flow with a list view on the left, and a detail view on the right. When the screen is created the right side is empty and no item on the left is selected. How can I load the first item by default? I found this post which is similar to my problem: Select the first item by default in a Master Detail flow The code in my ListFragment looks like this: @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated

问题 I had made a class in C# Windows form to represent my database.
