B4A Library Digital Clock

A simple wrap for this Github project

Sure you will figure it out. Posting:
1. B4A sample project
2. B4A library files (jar and xml - copy them to your additional library folder
3. The java code (amended project and wrapper) - change it to your licking.

Touch the clock to change the colors

Sample B4A Code:

#Region  Project Attributes
    #ApplicationLabel: DigitalClock
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

    Private dc1 As DigitalClock
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("main")
    Dim clkclr() As Int = Array As Int (Colors.Yellow, Colors.Green, Colors.Magenta, Colors.Cyan, Colors.Red)
    dc1.ClockColors = clkclr
    dc1.SelectedColorIndex = 0
    dc1.ClockTextColor = Colors.White

End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub dc1_clock_touched(newcolor As Int)
    Log("newcolor = " & newcolor)
End Sub

I have problems with the integrated digital.ttf font - i get a java runtime exception: Font asset not found digital.ttf
I see the font in the files folder, i get warning #15 - file digital.ttf is not used.
i tried to load the font before it is used in loadlayout, but i find no way to help digital clock to use this font.
Second question: is any kind of localisation integrated or to i have to change the java source for it?
Thanks!

Have added a method so that you can set the TypeFace from within B4A
Lib should show as V1.01. Download and copy attached jar and xml to your additional libs folder

    Dim myfont As Typeface = Typeface.LoadFromAssets("digital.ttf")
   
dc1.ClockTypeFace = myfont

For second question - this is some of the code in the original project:

    private int[] getDateTime(){

        //get date & time
        Calendar calendar = Calendar.getInstance(Locale.getDefault());
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH);
        int day = calendar.get(Calendar.DAY_OF_MONTH);
        int day_of_week = calendar.get(Calendar.DAY_OF_WEEK);
        int ss = calendar.get(Calendar.SECOND);
        int mm = calendar.get(Calendar.MINUTE);
        int hh = calendar.get(Calendar.HOUR_OF_DAY);

        int[] values = {year,month,day,day_of_week, hh, mm, ss };
        return values;

    }

    private String getDayOfWeek(int day_of_week){
        switch(day_of_week){
            case Calendar.MONDAY:
                return "MON";
            case Calendar.TUESDAY:
                return "TUE";
            case Calendar.WEDNESDAY:
                return "WED";
            case Calendar.THURSDAY:
                return "THU";
            case Calendar.FRIDAY:
                return "FRI";
            case Calendar.SATURDAY:
                return "SAT";
            case Calendar.SUNDAY:
                return "SUN";
        }

        return null;

    }

Thanks for your work; i think my problems raised from the fact, that i wanted to implement this clock element in an kiosk mode app. Your demo is working now; when in try to use exactly the same code inside my kiosk mode tryout i get:

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.example.damian.digitalclock.MyView.setClockTypeFace(android.graphics.Typeface)' on a null object reference

So i think i have to remove the changes, that i made for kiosk mode on my mobile and try it further. If i find the source of the problem i will inform you further.
Thanks!
