问题 The problem : I have one class and one activity: The class do the logic and use a complex algorithms that manipulate Textview and ImageView from the activity What I'm doing : In activity : static TextView txt1, txt2, txt3, txt4; so I can use in the class : Activity.txt1 Is it something bad in Android programming ? I wanted to learn best practise. So if you have a better method I would take it. Thanks 回答1: I can't see any reason you'd ever want to do that. Static variables are shared between

问题 I'm developing an application with the user default authentication provided by Django (and django-registration-redux ). Also in docs, they recommend to link the user profile with a OneToOneField in a different model,as explain here: https://docs.djangoproject.com/en/1.10/topics/auth/customizing/ The problem is: How to build a registration view that includes the profile form? Note that it's only creating a user account with the basic data without profile info. I already have worked in other

问题 I am attempting to create a dynamic table in my view that will be dynamically generated depending on the type of model I send to the view. So, I basically have two actions: public IActionResult People() { List<Person> lst = new List<Person>(); // Add data... return View("Table", lst); } public IActionResult Teams() { List<Team> lst = new List<Team>(); // Add data... return View("Table", lst); } Now I would like to have the same view that will show a list of people / teams, so that I don't

问题 (forgive me - I'm new to both StackOverflow & SQL) Tl;dr - When using @@identity (or any other option such as scope_identity or output variable), is it possible to also use a view? Here is an example of a stored procedure using @@identity : --SNIP-- DECLARE @AID INT DECLARE @BID INT INSERT INTO dbo.A (oct1) VALUES (@oct1) SELECT @AID = @@IDENTITY; INSERT INTO dbo.B (duo1) VALUES (@duo2) SELECT @BID = @@IDENTITY INSERT INTO dbo.tblAB (AID, BID) VALUES (@AID, @BID) GO Longer: When inserting

问题 My goal is to create a view in SwiftUI that starts with 0. When you press the view, a timer should start counting upwards, and tapping again stops the timer. Finally, when you tap again to start the timer, the timer should begin at 0. Here is my current code: import SwiftUI struct TimerView: View { @State var isTimerRunning = false @State private var endTime = Date() @State private var startTime = Date() let timer = Timer.publish(every: 0.001, on: .main, in: .common).autoconnect() var tap:

问题 For the past year and a half, I've maintained a monolithic buffer in Org Mode for my engineering notes with my current employer. Despite containing mostly pointers to other documents, this file has become quite large by human standards (48,290 lines of text), while remaining trivially searchable and editable through programmatic means (read: grep and Org Mode tag search). One thing bothers me, though. When I perform a tag search using Org Mode 6.33x, Org's sparse tree view retains the folded
