QUESTION
Background
I have an Android app that displays the time as a string in a textview in the main activity. I update the text as each minute passes. When the power button is hit on my phone, the phone is locked and the app pauses (it is not destroyed). When the phone is unlocked, the app resumes, and things continue as normal.
Problem
After unlocking the phone, the app pops up and resumes, but initially, the time displayed in the textview is the time from when the app was locked. About a second later the time updates from me explicitly setting the time on resume.
...ANSWER
Answered 2021-Jun-03 at 09:14Why don't you try overriding the onStart, if Im not mistaken it is called before onResume and by then the app will not be shown to the user just yet.
QUESTION
I tried to create a clock in Android Studio using Kotlin. I created a View with clock you can see code down.
...ANSWER
Answered 2021-Mar-28 at 18:51The stack trace says that you use androidx.constraintlayout.Dwidget.ConstraintLayout (notice the D between the . and the widget) in some layout file. Presumably, that is your activity's layout file, given how the stack trace is set up.
Regardless, find the layout with this extra D, and remove the D.

ANSWER
Answered 2020-Oct-13 at 18:37Several things ... you dispatch on the main queue but you are already on the main queue so you are swamping the main queue. Also, you dispatch async so the queue gets clogged pretty soon I think. Still I would think the hardware should be able to handle it actually so I am not entirely sure why it freezes, but I think you need to do it a bit better.
Also, importantly, if you build a stopwatch you should not count yourself. Sure, use a timer to regularly update the stopwatch, but in stead of counting yourself you should use the wall clock for the time. The way you do it now will be very inaccurate and the inaccuracies will accumulate over time.
At present you fire every 10 millis. Maybe fire every 100 and then update your stopwatch but read from the device's internal clock. This in itself is problematic, see How can I get the Correct Current Time in iOS? for some ideas on how to do that.
When the stopwatch starts note the time e.g.
QUESTION
I was able to change the color setting for the clock view (That was helpful https://www.tutorialsbuzz.com/2019/09/android-timepicker-dialog-styling.html)
But I wasn't so successful at the second view (press the keyboard icon at the bottom left of the first image). How to change the color of SubTitle, InputField and description (center of the image that looks pure black)? Has anyone an idea?
Is there a documentation that I overlook? Would be great to have a list with all keys like "android:numbersTextColor" etc. for the color pallet of the second view.
I appreciate your time and effort. Thanks :-)
Edit
"Leon Lu - MSFT" thanks for your answer. That made it possible to style the view under "Keyboard". Is it possible to set different colors for the text above and below the input field, the "AM"/"PM" text and "cancel"/"ok"?
Unfortunately the clock view changed into this after applying the provided style.

I have a rudimentary ClockView build with SwiftUI. :) My question is if applying drop shadows to the clock-hands is easily possible with this approach or if i need a different layout and grouping of the elements? I've tried to find a way to add shadows to Path, but got stuck. Thank you.

QUESTION
(Xcode 11.4 · Swift 5 · iOS Target 13.4)
The stripped down SwiftUI iOS code below creates a View that contains a clock's smoothly rotating secondhand. It works fine except that the animation runs anticlockwise when the seconds value changes from 59 to 0. How can I force the secondhand to rotate clockwise only?
...ANSWER
Answered 2020-Mar-26 at 12:22Try the code below. The strategy here is to turn off the animating of the moving hand once a minute. When the animation is off the angle can be adjusted without getting un-wanted wrap-around rotation. There might be an easier way to do this, but this definitely does the job.
QUESTION
I'm trying to draw an oval on a JFrame using Graphics2D, I want it to resize with the window which technically it does, it just not drawing about a 3rd of the oval. It's definitely something I'm doing wrong, I'm new to the Graphics2D part of Java.
I wasn't sure if it was my computer so I have tried running my code on a different PC to have it happen again so I'm not sure where I've gone wrong.
...ANSWER
Answered 2019-Oct-06 at 08:38I am not getting the error you get. However, this is not the right way to do custom painting in Swing. I suggest you to take a look on how to perform custom painting. Long story short though, this thing you are trying with the while condition will not work. Instead, let the component to be painted according to its parent size and coordinates without having to set them explicit :
QUESTION
I'm trying to reference App.xaml's ResourceDictionary from a separate WPF window. I want to use resources from there in different windows, and this seems like the recommended way to do it. Unfortunately, I don't seem to be able to effectively reference App.xaml from the other window. Here is my App.xaml:
...ANSWER
Answered 2019-Jun-06 at 07:31You can't load App.xaml like you're trying to do because it's not actually a ResourceDictionary. You can only specify ResourceDictionary files as the target of Source.
However, if you declare a resource in App.xaml, you can reference it anywhere without needing to load the file it's in. That's done for you automatically. Therefore, you can reference your converter at any time with {StaticResource PriorityToIconConverter}.
Note that if you moved it from the default starting location (the base project folder) you may have to update its location. Right click your project, then Properties. Navigate to the "Application" tab (should be the uppermost element on the left-hand sidebar) and look for the "Startup object" field. Set that to [ProjectName].[Namespace?].[Namespace?].App. When I tested it, mine worked without needing to manually change the location, but your setup may be different.

I'm writing an app to show a simple digital clock in Android and I need to scale the font size of the TextView so that it fills the screen as much as possible. I found a quite simple way to scale text size using displayMetrics but it doesn't work correctly on some devices. What I want to achieve looks like this:
I would work only in landscape mode, and I would like it to run on my old smartphones and tablets lying around as well as on newer devices. So I have a variety of screen types to cater to.
To scale the font I do the following

Answered 2018-Jul-13 at 13:40Sizes haven't been determined when createPartControl is called.
There will be a Resize event when the size is set.
