QUESTION
so I have tried 2 different ways to display the timer count down on the screen.
the code will print to the console but not to the UITextView (in both loop cases) in the repeat the UITextView ends with a 0 and that is the only thing it displays other than original txt "time count".... in the case where the commented loop is implemented the UITextView only displays the 1 (end of count down)... why is it printing to the console though these commands are in the same brackets as UITextView and they repeat
the image is after running code and clicking Soft (this is spin off of app brewery egg timer)
...ANSWER
Answered 2021-Apr-26 at 17:27You never (well, almost never) want to use sleep().
The reason your text is not updating is because you are running closed-loops that never allow UIKit to update the view.
What you want to do instead is to use a repeating Timer with a one-second interval. Each time the timer fires, decrement your counter and update the UI. When the counter reaches Zero, stop the timer.
Here's a simple example:
QUESTION
I was learning foreground services and I created a notification channel to make sure that it keeps the service active. The thing is, the app doesn't stop even when I invoke the stopService method. The notification sure does disappear, but the app is still shown to be running in the Running Apps page of my phone.
In this particular app, I have created a Service that Toasts out Random numbers until the Service is running. The thing is when I press the button to stop, it removes the notification. But the Toasts continue on and on and the app is shown to be in progress in the Running Apps page. Here's the code.
MainActivity.class

Answered 2020-Apr-21 at 15:49You are stopping the service, but the thread is still executing, you need to stop CountDownTimer, maybe this will work. I suggest that you assign a global variable CountDownTimer timer and in the destroy call timer.cancel();
• Try calling stopSelf();

i've seen some answers suggest that i should change to this line of code
...ANSWER
Answered 2020-Mar-22 at 19:56From the crash log is says there is a class cast exception. You used the GridLayout from the androidx library in the xml whereas, you are trying to cast it to the GridLayout from the android library modules in your java class. Hence you are getting this exception. You need to use the same version for both of your layout xml and the java class.
You need to import the following in your Java class.
QUESTION
I have an Activity with WebView and my own AppBarLayout. I want to implement hiding/showing the AppBarLayout with animation when scrolling the WebView, like in the Google Chrome app.
I tried different ways.
ObservableWebView, but it doesn't work correctly, it doesn't always show AppBar, especially if the page is short.
ConstraintLayout with animations. Something similar, but still not the same as in Google Chrome.
Coordinator layout. This is the best variant, I think. But it have some bugs.
I have wrote the code of layout like this:

QUESTION
I have a TextView i want to hide, quite easy I thought. But this is giving me a headache. The www did as well not have an answer.
I "fixed" the problem by calling timer.setText("");, to the user it looks like it dissapred. I have many Views, so I have this int visibility = warmup ? View.GONE : View.VISIBLE; all the other controls hide perfect, except this one. I hard coded it as well to View.GONE, with the same result.
ANSWER
Answered 2019-Jun-19 at 13:36timer.setVisibility(View.INVISIBLE) // This will hold the position and space but just hide the view.
timer.setVisibility(View.GONE) // This will not hold the position and space. It will disapear.
QUESTION
I wrote the code for a timer like below, but if I wrote it in a separate method, not in pre-created method like onCreate(), it doesn't work as I expected. But if I put the body part of the method in 'onCreate()', it works just as fine.
Are there some rules or differences between writing a method in 'onCreate()' method or independently?
...ANSWER
Answered 2019-Jan-31 at 02:19onCreate() is automatically called "under the hood" by the Activity's class. It is automatically called when the activity is first created. See the Android documentation on Activity Lifecycles.
Without knowing much of your Activity's implementation, I would say putting that timer's code in the onCreate method or have the onCreate method call that method.
QUESTION
I am new to android and currently working with timers.
From https://developer.android.com/reference/android/os/CountDownTimer I can understand that CountDownTimer is an abstract class.
From my understanding of abstract class we cannot create an object of an abstract class and generally if we try to create an object of an abstract class the IDE will show an error.
But the below code which I tried did not show any error.
I checked on stackoverflow and other sites to see I was able to create an object of CountDownTimer but could not find any explanation.
Below is excerpts from my code which is working.
...ANSWER
Answered 2019-Jan-20 at 12:00What your code is actually doing is creating an inner anonymous class that extends CountDownTimer, implements it and creates an object of that "new" class.
CountDownTimer is abstract, so yes, you can't just do 'new CountDownTimer(30000, 1000)' alone.
But your code opens it up and implements both 'onTick' and 'onFinish' functions (which are the only abstract functions in the CountDownTimer class.

I am developing a brain trainer application for Android users. Problem is that sometimes I got the wrong result when I try to add two numbers together (as an example: question is 2 + 2 and when I press the button and displaying the result is wrong.) but it occurs randomly. Appreciate if someone could assist me to correct way. Thanks.
This is MainActivity.java

Answered 2018-Jul-25 at 02:25You have set the wrong tags for the buttons. The tags should be 0 to 3 for button1 to button4.
QUESTION
i need a countDownTimer keep running when i swap between activities.. i have more than one activity, i put the countDownTimer in the main activity but when i swap to another activity and back to the main activity it turns back to count again from the start, i believe because the method countDownTimer is onCreate method.
So, how should I go about doing this?
...ANSWER
Answered 2018-Jul-10 at 19:46Maybe this is a little far fetched, but the way that I think to solve this issue and not worrying for the Activities is using an IntentService.
Even if you store some sort of value in the Bundle of the onSaveInstance() hook method this can lead to some pretty messy results if you enable the "Don't keep activities" flag in the device's settings.
What I would do is create an IntentService that when It's triggered starts the countdown, then It broadcast the changes of that countdown through EventBus/Otto/BroadcastReceiver back to the UI.
Another way of doing it is having the countdown instance in your Application class, and check it from there.
I would go with the IntentService solution because having a countdown instance running in the Application class sounds a little off.
Let me know if you want any specifics on how to implement the IntentService but a little bit of Googling should show you how to do it.
