android: how to make a child view overlap the parent?

主宰稳场 提交于 2019-12-05 02:37:15
I need to implement the layout as in the picture. Parent and Sibling are in a vertical LinearLayout. So I need to make a child view to overlap it's parent. Can I do that in android? If: sibling is a sibling of parent parent is a ViewGroup and you really want child to be a child of parent then maybe you could consider using android:clipChildren set to false on parent . I was actually just looking at an example of a FrameLayout that had a TextView overlaid on top of an ImageView. So, there are obviously multiple ways to get it done. Your next question might be which one is best ... to that I

Difference between javascript .childNodes & .children

问题 I have been working with javascript for a week now. I am currently working on making things work/change through nodes. But I have been noticing something strange, well for an unskilled javascripter it is. I have a structure in my site like this: <html> <head> <title>....</title> <link/> <script></script> </head> <body> <div 1> <div 2></div> </div> </body> </html> When I am trying to find a childnode with the next function: var headerBox = document.body.childNodes; var txt = ""; for (var x = 0

WPF: INotifyPropertyChanged And derived properties on different objects

那年仲夏 提交于 2019-12-04 22:43:17
Recently I inherited a pretty big project developed in C# and WPF. It uses bindings along with the INotifyPropertyChanged interface to propagate changes to/from the View. A little preface: In different classes I have properties that depend on other properties in the same class (think for example the property "TaxCode" that depends on properties like "Name" and "Lastname"). With the help of some code I found here on SO (can't find again the answer though) I created the abstract class "ObservableObject" and the attribute "DependsOn". The source is the following: using System; using System

ClearCase, use clearfsimport to perform brute force update

北城余情 提交于 2019-12-04 19:16:51
I've messed up my views a bit (big surprise for CC) and I have a child stream that has most of what I need, but not all. My parent stream needs to be updated, but I can't because of some issues (maybe evil twins I dunno). Is it possible/wise to do the following 1) clear all elements in the parent stream 2) use clearfsimport to perform mass update on child stream 3) deliver child stream to parent This is of course dependent on the fact that child stream elements are not deleted when deleted from parent. Should I just clear out all elements of both views and start over? Any suggestions would be

How to handle saving on child context but the objected is already deleted in parent context?

…衆ロ難τιáo~ 提交于 2019-12-04 17:09:59
I have core data nested contexts setup. Main queue context for UI and saving to SQLite persistent store. Private queue context for syncing data with the web service. My problem is the syncing process can take a long time and there are the chance that the syncing object is deleted in the Main queue context. When the private queue is saved, it will crash with the "Core Data could not fulfill faulted" exception. Do you have any suggestion on how to check this issue or the way to configure the context for handle this case? There is no magic behind nested contexts. They don't solve a lot of

Ruby on Rails: Building a child with default values when its parent is created

元气小坏坏 提交于 2019-12-04 10:36:46
问题 I have a parent and child model relationship. In the child's migration.rb, the child model's columns each have default values (except the parent_id column). When I make a new parent object, how can I make it so that a child object is created and saved into its table with the data from the default values along with the parent_id? I'm thinking that it will have to do with something like an after_create on the parent model, but I'm not sure how to set it up. 回答1: Revised: I revised the answer to

How to link parent and children to each other?

纵然是瞬间 提交于 2019-12-04 08:16:25
Having two simple classes; one with only parent attribute, and one with both parent and children attributes. This means that the one with both parent and children inherits from the one with only parent . Here's the class with only parent attribute. Let's call it Child since it can only be a child, not a parent. I'll use a method set_parent() to make it more clear, but I would use a setter in my actual code. class Child(object): def __init__(self, parent=None): self.__parent = None self.set_parent(parent) def set_parent(self, parent): # Remove self from old parent's children if self.__parent:
