B4A Library Clocks library

This small library has three time related views. A DigitalClock, an AnalogClock and a Chronometer that can be used as a stopwatch.

Offset for Clocks

Quick'n sweet question, Andrew, could the Clocks Lib be modified so as to accept a time offset? Currently Clocks reads system time. If it could be offset, say, with zone times (in units of TicksPerHour), then, for instance, a world time clock could be implemented in no time. Please sleep it over.

I'm afraid that is not possible.

Thanks for your prompt response, Andrew.

How to set background image? I tried but not work.

Aclock.SetBackgroundImage(LoadBitmap(File.DirAssets, "clock1.png"))

 

[agraham]

In what way does it not work? I have cut and pasted your line of code into the demo, added a png file to the assets and it works fine for me.

 

[susu]

My bad, I got "Aclock.Color = Colors.Black" also so that it doesn't work, sorry Agraham
Is there a way to change color of the clock hands?

 

[agraham]

Is there a way to change color of the clock hands?

No. AnalogClock inherits from the basic View object and has no additional methods or properties so you can't do some things you might expect, like change the time or the colour of the hands.

stopper

Hi

I am using the stopper (Chrono) from the example
but when I issue Chrono.Stop, the display is stopping, but when I resume it again Chrono.Start, the display is jumping to the future
meaning if I stopped it on 00:10 waited 10 sec, and start it again, it will continue from 00:20 and not 00:10
what is the problem?
and how can I reset the counter again? (start from 0)

thanks
Shay

Look at the code in the demo which starts, stops and resets the chronometer and also maintains its count across Pause and Resume events.

Look at the help, especially for the BaseTime method.

Chron Countdown

Could someone please help with a chrono coundown timer.I have been trying this for some hours .

Hello Andrew,
Just a quick note to thank you very much, indeed, for the clocks library you created.
I am using the analog clock frequently for applications in full screen mode.
Cheers
Robert

Analog Clock Scale

Hello Andrew,

Is there a maximum value for clock width/height?

Panel1.Initialize("")
Activity.AddView(Panel1,10dip,10dip,Activity.Width-20dip,Activity.Width-20dip)
Clock.Initialize("")
Panel1.AddView(Clock,0,0,Panel1.Width,Panel1.Height)

won't draw the analog clock larger than Panel1.Width / 2.

 

[agraham]

There is no limit to the size of the actual view as you can see if you colour the background. However there does seem to be a limit to the size of the dial that seem to maximise at a size of 240 pixels. It looks like the view can scale the dial down for a smaller view but does not scale it up.

 

[alfcen]

Thanks a lot for your quick response. 240 pixels...that ties it.
No problem whatsoever, the clock is a great gadget for multi-purpose use.

Is it possible to hide the "small blocks for the hours"? And also to replace the stock pointer with own graphics?

I wish to display the Hour in the Chronometer and try the following code.

Sub Activity_Create(FirstTime As Boolean)
  ...
  Chrono.Initialize("Chrono")
  Activity.AddView(Chrono, 20dip, 60dip, 200dip, 60dip)
  Chrono.Color = Colors.RGB(255,102,0)
  Chrono.TextSize = 40dip
  Chrono.TextColor = Colors.RGB(250,235,215)
  Chrono.Gravity = Gravity.CENTER
  Chrono.Format = "H:MM:SS"
  ...
End Sub

Before the Chrono Start, it displays 00:00. After the Chrono Start, it displays H:MM:SS as attached images.

It works fine if we remove the line Chrono.Format = "H:MM:SS".

Please helps. Thanks.

 

[agraham]

Read the help. It's a straight copy of the Android help for Chronometer.setFormat. You cannot format the time display itself, merely substitute it for the "%s" in the format string.

Chrono.Format = "#-%s-#" displays "#-12:34-#"

 

[kawawong]

Thanks.

Have further tested and it can show in the format of H:MM:SS when the time elapsed for more than an hour. There is no need to set the format.

Miliseconds?

Maybe I'm missing something but I can't figure out how to get 1/10th of seconds in the chrono. :sign0104:

Is this not possible? I'd prefer to only have MM:SS.X where X is 1/10th fractions of the second value.

Hopefully i'm just missing something here...
