B4A Library PercentProgressBar

It wraps this Github project. Nothing spectacular but maybe someone will find a use for it.

1. B4A project
2. B4A library files
3. Java code
4. Zip file containing 2 x *.ttf files. Copy them to the /Files folder of the B4A project


Sample Code:
#Region  Project Attributes
    #ApplicationLabel: b4aPercentProgressBar
    #VersionCode: 1
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: landscape
    #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.
    Dim t As Timer

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 ppb1 As PercentCircularProgress
    Dim cnt As Int = 0
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    t.Initialize("t", 500)
    ppb1.BackgroundColor = Colors.Red
    ppb1.TextColor = Colors.Green
    ppb1.TextSize = 35
    ppb1.ProgressColor = Colors.Blue
    ppb1.BackgroundStrokeWidth = 12
    ppb1.ProgressStrokeWidth = 6
    ppb1.RoundEdge = True
    ppb1.Typeface = "Roboto-Regular.ttf"
    ppb1.Progress = cnt
End Sub

Sub Activity_Resume
    t.Enabled = True

End Sub

Sub Activity_Pause (UserClosed As Boolean)
    t.Enabled = False

End Sub

Sub t_tick()
    cnt = cnt + 1
    ppb1.Progress = cnt 
End Sub

Sub ppb1_progress_completed
    t.Enabled = False
End Sub

Sub ppb1_progress_changed(progress As Int)
    Log("progress = " & progress)
End Sub
