view

问题 I'm trying to make a View that will put a Blur() at the bottom of an iPhone layout, respecting safeareas and that I can easily reuse. Something like this: import SwiftUI struct SafeBottomBlurContainer: View { @Environment(\.colorScheme) var colorScheme var body: some View { GeometryReader { geometry in VStack { Spacer() ZStack { Blur(style: self.colorScheme == .dark ? .systemThinMaterialDark : .systemThinMaterialLight) .frame( width: geometry.size.width, height: geometry.safeAreaInsets.bottom

问题 In my current application I am using invalidate(Rect) to update a portion of my current view but as of API 28 this method is deprecated. So my questions are: 1.Are there any other way to update only a portion of view? 2.What are the consequences of using a deprecated method? 回答1: According to the android documentation, just call the invalidate() method as the redrawing area is calculated internally. From view docs This method was deprecated in API level 28. The switch to hardware accelerated

问题 I want to support language change (manually by user). I'm using react-native-i18n for that. I found how to change the displayed language at run time but I didn't find how to update the current view. My Code Environment Environment: Node: 8.9.4 Yarn: 1.3.2 npm: 4.0.5 Expected Behavior When I use I18n.locale ='en'; not in function.. just as it is, the text will be in English and when I use I18n.locale ='he'; the text will be in Hebrew.

问题 I've created a view to join two tables in Big Query. When I use that view as a data source in Data Studio I get a configuration error. The query used to create the view looks like this: SELECT emp.name, emp.gender, emp.age, pay.salary FROM [project:doug.employees] as emp JOIN [project:doug.payrates] as pay on emp.name = pay.name Within Big Query the view works as expected. I can query it without any problems. If I try to use the view directly as a data source in Data Studio, I get the

问题 We have a View (call it X) that is the base view called by 2 other views(call them Y and Z). Today we made a change to view X, after that view Y and Z started bringing back data that was incorrect. When we were in Management Studio and ran SELECT * FROM Y (which is exactly how the view is called in code) it would get back data that was incorrect. However, when we ran the actual SQL that the view contained it was fine. We tried a number of things until a colleague suggested adding a space to

问题 I am pretty new to MvvmCross and the mvvm pattern in general, so I started a small learning project and immidiatly ran into a wall. I based my application on the idea of having a MainView which contains a standard Menu and a child MvxWpfView . This ChildView should be a simple ReadMeView first, but on user input it should switch to an other View (the one with actual data on it). I already found a few articles about this issue but none of them worked or i wasn't able to follow. My setup : Core

问题 I have a view controller which has scroll view in it, and the scroll view has a view. So, view has a lot of buttons and labels which are being showed depending on data which comes from api. And I have a button after pressing it, I want to reload a views (it's content). 回答1: one of the easy hack and NOT the recommended way is to do self.view.setNeedsLayout() also you can do self.viewDidLoad() OR self.viewWillAppear(true) well the different recommended approaches you can use are the following
